TDIV First Trust VI First Trust Nasdaq Technology Dividend Index Fund

Investment Objective

The First Trust Dorsey Wright DALI 1 ETF (the “Fund”) seeks investment results that correspond generally to the price and yield (before the Fund’s fees and expenses) of an index called the Nasdaq Dorsey Wright DALI 1 Index (the “Index”).

Fees and Expenses of the Fund

The following table describes the fees and expenses you may pay if you buy and hold shares of the Fund. Investors purchasing and selling shares may be subject to costs (including customary brokerage commissions) charged by their broker, which are not reflected in the table below.

Shareholder Fees

Maximum Sales Charge (Load) Imposed on Purchases (as a percentage of offering price)

None

    

Example

The example below is intended to help you compare the cost of investing in the Fund with the cost of investing in other funds. This example does not take into account customary brokerage commissions that you pay when purchasing or selling shares of the Fund in the secondary market.

The example assumes that you invest $10,000 in the Fund for the time periods indicated. The example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain at current levels. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

1 Year	3 Years	5 Years	10 Years
$93	$290	$504	$1,120

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 31% of the average value of its portfolio.

Principal Investment Strategies

Under normal conditions, the Fund will invest at least 90% of its net assets (including investment borrowings) in the equity securities that comprise the Index. The Fund, using an indexing investment approach, attempts to replicate, before fees and expenses, the performance of the Index. The Fund’s investment advisor seeks a correlation of 0.95 or better (before fees and expenses) between the Fund’s performance and the performance of the Index; a figure of 1.00 would represent perfect correlation. The Index is owned and was developed by Nasdaq, Inc. (the “Index Provider”). The Index Provider may, from time to time, exercise reasonable discretion as it deems appropriate in order to ensure Index integrity. The Index consists exclusively of U.S.-listed exchange-traded funds (“ETFs”). Certain ETFs in which the Fund invests may be advised by First Trust Advisors L.P., the Fund’s investment advisor.

The Index evaluates four broad asset classes (U.S. equity securities, international equity securities, fixed income securities and commodities) and seeks to determine which of the four is most likely to experience the best investment performance until the next Index evaluation date (generally the second and fourth Friday of each month). The Index has been designed based upon the principle that the asset class exhibiting the highest levels of “relative strength,” based on current prices, will be the asset class with the best performance over the near term. A relative strength calculation is an objective method of comparing two investment options to determine which of the two is exhibiting greater forward price momentum.

For the purpose of comparing the asset classes, each asset class is represented by a roster of indices and/or one or more ETFs that principally track or invest in the securities that comprise each asset class, and collectively provide diversified exposure to each asset class. To determine which of the four asset classes is exhibiting the greatest price momentum, the Index compares the relative strength of each component (ETF or index) of each asset class against each component of each of the other three asset classes. To make this

comparison, the closing price of the two ETFs/indices being compared are divided against each other and then multiplied by 100. This number is then charted. When the same calculation is run the next day, if the number increases for a given asset class, it is charted as an “X.” If it decreases, it is charted as an “O.” This is known as “point and figure” charting. The Index utilizes this technique by comparing each component of each asset class against the components of each of the other three asset classes and aggregating the information. The asset class with the greatest number of “Xs” is the asset class exhibiting the greatest relative strength and is therefore the asset class chosen for inclusion in the Index. The Index provides exposure to a single asset class at a time.

The point and figure relative strength comparison is generally used to determine the highest scoring asset class on a twice-monthly basis. The Index, and thus the Fund, will reconstitute and rebalance to reflect the asset class exhibiting the highest levels of relative strength. Once the asset class exhibiting the highest relative strength is determined, the Index is constituted and weighted pursuant to the individual methodology of the selected asset class, each of which is set forth below. Each ETF that is currently eligible for inclusion in the Index is set forth on Appendix A. The ETFs eligible for inclusion in the Index pursuant to the U.S. equity securities, international equity securities and commodities asset allocation are advised by First Trust Advisors L.P., the investment advisor to the Fund. The ETFs eligible for inclusion in the Index pursuant to the fixed income asset allocation are not advised by First Trust Advisors L.P. The list of ETFs eligible for inclusion in the Index may change from time to time pursuant to the methodology of the Index.

U.S. Equity Securities

•	65% of the Fund’s assets will be equally weighted among the constituents of the Dorsey Wright Focus Five Index (an index of ETFs designed to select the five sector/industry-based First Trust ETFs exhibiting the greatest relative strength).
•	35% of the Fund’s assets will be equally weighted among the First Trust Large Cap Growth AlphaDEX® Fund (an ETF that provides exposure to large capitalization U.S. issuers that have exhibited higher levels of growth potential) and First Trust Small Cap Growth AlphaDEX® Fund (an ETF that provides exposure to small capitalization U.S. issuers that have exhibited higher levels of growth potential).
•	The Index will re-balance back to the 65% and 35% target weights quarterly. The Index may re-constitute periodically in response to changes in the composition of the Dorsey Wright Focus Five Index.

International Equity Securities

•	65% of the Fund’s assets will be equally weighted among the constituents of the Dorsey Wright International Focus Five Index (an index of ETFs designed to select the five country/region-based First Trust ETFs exhibiting the greatest relative strength).
•	35% of the Fund’s assets will be equally weighted among the First Trust Emerging Markets AlphaDEX® Fund (an ETF that provides exposure to equity securities issued by companies operating in emerging markets) and First Trust Developed Markets ex-US AlphaDEX® Fund (an ETF that provides exposure to equity securities issued by companies operating in non-U.S. developed markets).
•	The Index will re-balance back to the 65% and 35% target weights quarterly. The Index may re-constitute periodically in response to changes in the composition of the Dorsey Wright International Focus Five Index.

Fixed Income Securities

•	65% of the Fund’s assets will be equally weighted among three ETFs that seek broad exposure to the U.S. investment grade fixed income securities market.
•	35% of the Fund’s assets will be equally weighted among the constituents of the Dorsey Wright Fixed Income Model (a model that seeks to select four ETFs that invest principally in fixed income securities exhibiting the greatest relative strength).
•	The Index will re-balance back to the 65% and 35% target weights quarterly. The Index may re-constitute periodically in response to changes in the composition of the Dorsey Wright Fixed Income Model.

Commodities

•

First Trust Global Tactical Commodity Strategy Fund (an ETF that invests in a combination of exchange-listed commodity futures contracts and commodity-linked instruments through a wholly-owned Cayman subsidiary with the objective of providing investors with commodity exposure) is included in the Index and given a weight of 100%.

The Index is rebalanced quarterly and reconstituted periodically and the Fund will make corresponding changes to its portfolio shortly after the Index changes are made public. The Index’s quarterly rebalance and periodic reconstitution schedule may cause the Fund to experience a higher rate of portfolio turnover. The Fund will be concentrated in an industry or a group of industries to the extent that the Index is so concentrated. To the extent the Fund invests a significant portion of its assets in a given jurisdiction or investment sector, the Fund may be exposed to the risks associated with that jurisdiction or investment sector.

As of March 31, 2020, the Index was allocated to the Fixed Income Securities asset class and was composed of the ETFs set forth below.

1.	iShares Core U.S. Aggregate Bond ETF
2.	Vanguard Total Bond Market ETF

3.	Schwab U.S. Aggregate Bond ETF
4.	iShares iBoxx $ Investment Grade Corporate Bond ETF
5	iShares 20+ Year Treasury Bond ETF
6.	iShares 7-10 Year Treasury Bond ETF
7.	iShares MBS ETF

The Fund is classified as “non-diversified” under the Investment Company Act of 1940, as amended (the “1940 Act”).

Principal Risks

You could lose money by investing in the Fund. An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other governmental agency. There can be no assurance that the Fund’s investment objective will be achieved. The order of the below risk factors does not indicate the significance of any particular risk factor.

ASSET CONCENTRATION RISK. Since the Index, and therefore the Fund, may be composed of a very small number of ETFs (including a single ETF), the Fund’s performance may be hurt disproportionately and significantly by the poor performance of those ETFs to which it has significant exposure. Asset concentration makes the Fund more susceptible to any single occurrence affecting the underlying ETFs and may subject the Fund to greater market risk than more diversified funds.

AUTHORIZED PARTICIPANT CONCENTRATION RISK. Only an authorized participant may engage in creation or redemption transactions directly with the Fund. A limited number of institutions act as authorized participants for the Fund. To the extent that these institutions exit the business or are unable to proceed with creation and/or redemption orders and no other authorized participant steps forward to create or redeem, the Fund’s shares may trade at a premium or discount to the Fund’s net asset value and possibly face delisting.

CALL RISK. Certain ETFs in which the Fund may invest hold debt securities that subject them to call risk. Some debt securities may be redeemed, or “called,” at the option of the issuer before their stated maturity date. In general, an issuer will call its debt securities if they can be refinanced by issuing new debt securities which bear a lower interest rate. An underlying ETF is subject to the possibility that during periods of falling interest rates an issuer will call its high yielding debt securities. An underlying ETF would then be forced to invest the proceeds at lower interest rates, likely resulting in a decline in the underlying ETF’s income.

CLEARING BROKER RISK. To the extent the Fund invests in ETFs which invest in commodity futures contracts through a clearing broker, the failure or bankruptcy of such a clearing broker could result in a substantial loss of Fund assets. Under current Commodity Futures Trading Commission (“CFTC”) regulations, a clearing broker maintains customers’ assets in a bulk segregated account. If a clearing broker fails to do so, or is unable to satisfy a substantial deficit in a customer account, its other customers may be subject to risk of loss of their funds in the event of that clearing broker’s bankruptcy. In that event, the clearing broker’s customers, such as an underlying ETF, are entitled to recover, even in respect of property specifically traceable to them, only a proportional share of all property available for distribution to all of that clearing broker’s customers.

COMMODITIES RISK. Certain ETFs in which the Fund may invest have exposure to commodities. Commodity prices can have significant volatility, and exposure to commodities can cause the value of an underlying ETF’s shares to decline or fluctuate in a rapid and unpredictable manner. The values of physical commodities may be affected by changes in overall market movements, real or perceived inflationary trends, commodity index volatility, changes in interest rates or currency exchange rates, population growth and changing demographics, international economic, political and regulatory developments, and factors affecting a particular region, industry or commodity, such as drought, floods, or other weather conditions, livestock disease, changes in storage costs, trade embargoes, competition from substitute products, transportation bottlenecks or shortages, fluctuations in supply and demand, and tariffs. The commodity markets are subject to temporary distortions or other disruptions due to, among other factors, lack of liquidity, the participation of speculators, and government regulation and other actions.

COMMODITY REGULATORY RISK. Certain ETFs in which the Fund may invest hold commodity-linked derivative instruments that subject them to commodity regulatory risk. The investment decisions of such underlying ETFs may have to be liquidated at disadvantageous times or prices, to avoid exceeding any applicable position limits established by the CFTC, potentially subjecting an underlying ETF to substantial losses. The regulation of commodity transactions in the United States is subject to ongoing modification by government, self-regulatory and judicial action. The effect of any future regulatory change with respect to any aspect of an underlying ETF is impossible to predict, but could be substantial and adverse to an underlying ETF.

COMMODITY-LINKED DERIVATIVES RISK. Certain ETFs in which the Fund may invest hold commodity-linked derivatives. Investments linked to the prices of commodities may be considered speculative. Significant investment exposure to commodities may subject the Fund to greater volatility than investments in traditional securities. Therefore, the value of such instruments may be volatile and fluctuate widely based on a variety of macroeconomic factors or commodity-specific factors. At times, price fluctuations may be quick and significant and may not correlate to price movements in other asset classes. A liquid secondary market may not exist for certain commodity-linked derivatives, which may make it difficult for the Fund to sell them at a desirable price or at the price at which it is carrying them.

CONVERTIBLE SECURITIES RISK. Certain ETFs in which the Fund may invest hold convertible securities. A convertible security has characteristics of both equity and debt securities and, as a result, is exposed to risks that are typically associated with both types of securities. The value of convertible securities may rise and fall with the market value of the underlying stock or, like a debt security, vary with changes in interest rates and the credit quality of the issuer. A convertible security tends to perform more like a stock when the underlying stock price is high relative to the conversion price and more like a debt security when the underlying stock price is low relative to the conversion price.

COUNTERPARTY RISK. Certain ETFs in which the Fund may invest hold securities that subject them to counterparty risk. Underlying ETF transactions involving a counterparty are subject to the risk that the counterparty will not fulfill its obligation to the underlying ETF. Counterparty risk may arise because of the counterparty’s financial condition (i.e., financial difficulties, bankruptcy, or insolvency), market activities and developments, or other reasons, whether foreseen or not. A counterparty’s inability to fulfill its obligation may result in significant financial loss to an underlying ETF. An underlying ETF may be unable to recover its investment from the counterparty or may obtain a limited recovery, and/or recovery may be delayed.

COVENANT-LITE LOAN RISK. Certain ETFs in which the Fund may invest hold covenant-lite loans. Covenant-lite loans contain fewer maintenance covenants, or no maintenance covenants at all, than traditional loans and may not include terms that allow the lender to monitor the financial performance of the borrower and declare a default if certain criteria are breached. This may hinder an underlying ETF’s ability to reprice credit risk associated with the borrower and reduce the underlying ETF’s ability to restructure a problematic loan and mitigate potential loss. As a result, an underlying ETF’s exposure to losses on such investments is increased, especially during a downturn in the credit cycle.

CREDIT RISK. Certain ETFs in which the Fund may invest hold securities that subject them to credit risk. An issuer or other obligated party of a debt security held by an underlying ETF may be unable or unwilling to make dividend, interest and/or principal payments when due. In addition, the value of a debt security may decline because of concerns about the issuer’s ability or unwillingness to make such payments.

CURRENCY RISK. Certain ETFs in which the Fund may invest hold investments that are denominated in non-U.S. currencies, or in securities that provide exposure to such currencies, currency exchange rates or interest rates denominated in such currencies. Changes in currency exchange rates affect the value of investments denominated in a foreign currency, and therefore the value of such investments in an underlying ETF’s portfolio. An underlying ETF’s net asset value could decline if a currency to which an underlying ETF has exposure depreciates against the U.S. dollar or if there are delays or limits on repatriation of such currency. Currency exchange rates can be very volatile and can change quickly and unpredictably. As a result, the value of an investment in such an underlying ETF may change quickly and without warning.

CYBER SECURITY RISK. The Fund is susceptible to operational risks through breaches in cyber security. A breach in cyber security refers to both intentional and unintentional events that may cause the Fund to lose proprietary information, suffer data corruption or lose operational capacity. Such events could cause the Fund to incur regulatory penalties, reputational damage, additional compliance costs associated with corrective measures and/or financial loss. Cyber security breaches may involve unauthorized access to the Fund’s digital information systems through “hacking” or malicious software coding but may also result from outside attacks such as denial-of-service attacks through efforts to make network services unavailable to intended users. In addition, cyber security breaches of the issuers of securities in which the Fund invests or the Fund’s third-party service providers, such as its administrator, transfer agent, custodian, or sub-advisor, as applicable, can also subject the Fund to many of the same risks associated with direct cyber security breaches. Although the Fund has established risk management systems designed to reduce the risks associated with cyber security, there is no guarantee that such efforts will succeed, especially because the Fund does not directly control the cyber security systems of issuers or third-party service providers.

DEBT SECURITIES RISK. Certain ETFs in which the Fund may invest hold debt securities. Investments in debt securities subject the holder to the credit risk of the issuer. Credit risk refers to the possibility that the issuer or other obligor of a security will not be able or willing to make payments of interest and principal when due. Generally, the value of debt securities will change inversely with changes in interest rates. To the extent that interest rates rise, certain underlying obligations may be paid off substantially slower than originally anticipated and the value of those securities may fall sharply. During periods of falling interest rates, the income received by an underlying ETF may decline. If the principal on a debt security is prepaid before expected, the prepayments of principal may have to be reinvested in obligations paying interest at lower rates. Debt securities generally do not trade on a securities exchange making them generally less liquid and more difficult to value than common stock.

DEPOSITARY RECEIPTS RISK. Certain ETFs in which the Fund may invest hold depositary receipts. Depositary receipts may be less liquid than the underlying shares in their primary trading market. Any distributions paid to the holders of depositary receipts are usually subject to a fee charged by the depositary. Holders of depositary receipts may have limited voting rights, and investment restrictions in certain countries may adversely impact the value of depositary receipts because such restrictions may limit the ability to convert the equity shares into depositary receipts and vice versa. Such restrictions may cause the equity shares of the underlying issuer to trade at a discount or premium to the market price of the depositary receipts.

DERIVATIVES RISK. Certain ETFs in which the Fund may invest utilize derivatives. The use of derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments.

These risks include: (i) the risk that the counterparty to a derivative transaction may not fulfill its contractual obligations; (ii) risk of mispricing or improper valuation; and (iii) the risk that changes in the value of the derivative may not correlate perfectly with the underlying asset. Derivative prices are highly volatile and may fluctuate substantially during a short period of time. Such prices are influenced by numerous factors that affect the markets, including, but not limited to: changing supply and demand relationships; government programs and policies; national and international political and economic events, changes in interest rates, inflation and deflation and changes in supply and demand relationships. Trading derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities. Derivative contracts ordinarily have leverage inherent in their terms. The low margin deposits normally required in trading derivatives, including futures contracts, permit a high degree of leverage. Accordingly, a relatively small price movement may result in an immediate and substantial loss. The use of leverage may also cause an underlying ETF to liquidate portfolio positions when it would not be advantageous to do so in order to satisfy its obligations or to meet collateral segregation requirements. The use of leveraged derivatives can magnify potential for gain or loss and, therefore, amplify the effects of market volatility on share price.

EMERGING MARKETS RISK. Certain ETFs in which the Fund may invest hold securities of issuers located in emerging market countries. Investments in securities issued by companies operating in emerging market countries involve additional risks relating to political, economic, or regulatory conditions not associated with investments in securities and instruments issued by U.S. companies or by companies operating in other developed market countries. Investments in emerging markets securities are generally considered speculative in nature and are subject to the following heightened risks: smaller market capitalization of securities markets which may suffer periods of relative illiquidity; significant price volatility; restrictions on foreign investment; possible repatriation of investment income and capital; rapid inflation; and currency convertibility issues. Emerging market countries also often have less uniformity in accounting and reporting requirements, unsettled securities laws, unreliable securities valuation and greater risk associated with custody of securities. Financial and other reporting by companies and government entities also may be less reliable in emerging market countries. Shareholder claims that are available in the U.S., as well as regulatory oversight and authority that is common in the U.S., including for claims based on fraud, may be difficult or impossible for shareholders of securities in emerging market countries or for U.S. authorities to pursue. For funds that track an index, the index may not weight the securities in emerging market countries on the basis of investor protection limitations, financial reporting quality or available oversight mechanisms. Furthermore, investors may be required to register the proceeds of sales and future economic or political crises could lead to price controls, forced mergers, expropriation or confiscatory taxation, seizure, nationalization or creation of government monopolies.

EQUITY SECURITIES RISK. Certain ETFs in which the Fund may invest hold equity securities. The value of an underlying ETF’s shares will fluctuate with changes in the value of the equity securities in which it invests. Equity securities prices fluctuate for several reasons, including changes in investors’ perceptions of the financial condition of an issuer or the general condition of the relevant equity market, such as market volatility, or when political or economic events affecting an issuer occur. Common stock prices may be particularly sensitive to rising interest rates, as the cost of capital rises and borrowing costs increase. Equity securities may decline significantly in price over short or extended periods of time, and such declines may occur in the equity market as a whole, or they may occur in only a particular country, company, industry or sector of the market.

ETF RISK. The Fund’s investment in shares of ETFs subjects it to the risks of owning the securities underlying the ETF, as well as the same structural risks faced by an investor purchasing shares of the Fund, including authorized participant concentration risk, market maker risk, premium/discount risk and trading issues risk. As a shareholder in another ETF, the Fund bears its proportionate share of the ETF’s expenses, subjecting Fund shareholders to duplicative expenses.

EXTENSION RISK. Certain ETFs in which the Fund may invest hold debt securities that subject them to extension risk. Extension risk is the risk that, when interest rates rise, certain obligations will be paid off by the issuer (or other obligated party) more slowly than anticipated, causing the value of these debt securities to fall. Rising interest rates tend to extend the duration of debt securities, making their market value more sensitive to changes in interest rates. The value of longer-term debt securities generally changes more in response to changes in interest rates than shorter-term debt securities. As a result, in a period of rising interest rates, securities may exhibit additional volatility and may lose value.

FIXED-TO-FLOATING RATE SECURITIES RISK. Certain ETFs in which the Fund may invest hold fixed-to-floating rate securities. Fixed-to-floating rate securities are securities that have a fixed dividend rate for an initial term that converts to a floating dividend rate upon the expiration of the initial term. Securities with a floating or variable interest rate component can be less sensitive to interest rate changes than securities with fixed interest rates but may decline in value if their interest rates do not rise as much, or as quickly, as interest rates in general. While fixed-to-floating rate securities can be less sensitive to interest rate risk than fixed-rate securities they generally carry lower yields than similar fixed-rate securities.

FLOATING RATE SECURITIES RISK. Certain ETFs in which the Fund may invest hold floating rate securities. Floating rate securities are structured so that the security’s coupon rate fluctuates based upon the level of a reference rate. As a result, the coupon on floating rate securities will generally decline in a falling interest rate environment, causing an underlying ETF to experience a reduction in the income it receives from the security. A floating rate security’s coupon rate resets periodically according to the terms of the security. Consequently, in a rising interest rate environment, floating rate securities with coupon rates that reset infrequently may lag behind the changes in market interest rates. Floating rate securities may also contain terms that impose a maximum coupon rate the issuer will pay, regardless of the level of the reference rate which would decrease the value of the security.

FUTURES CONTRACTS RISK. Certain ETFs in which the Fund may invest hold futures contracts. Futures contracts are typically exchange-traded contracts that call for the future delivery of an asset by one party to another at a certain price and date, or cash settlement of the terms of the contract. The risk of a position in a futures contract may be very large compared to the relatively low level of margin an underlying ETF is required to deposit. In many cases, a relatively small price movement in a futures contract may result in immediate and substantial loss or gain to the investor relative to the size of a required margin deposit. In the event no secondary market exists for a particular contract, it might not be possible to effect closing transactions, and an underlying ETF will be unable to terminate the derivative. If an underlying ETF uses futures contracts for hedging purposes, there is a risk of imperfect correlation between movements in the prices of the derivatives and movements in the securities or index underlying the derivatives or movements in the prices of an underlying ETF's investments that are the subject of such hedge. The prices of futures contracts may not correlate perfectly with movements in the securities or index underlying them.

GAP RISK. Certain ETFs in which the Fund may invest are subject to gap risk which is the risk that a commodity price will change from one level to another between periods of trading. Usually such movements occur when there are adverse news announcements, which can cause a commodity price to drop substantially from the previous day’s closing price.

HIGH YIELD SECURITIES RISK. Certain ETFs in which the Fund may invest hold high yield securities. High yield securities, or “junk” bonds, are subject to greater market fluctuations, are less liquid and provide a greater risk of loss than investment grade securities, and therefore, are considered to be highly speculative. In general, high yield securities may have a greater risk of default than other types of securities and could cause income and principal losses for an underlying ETF.

HYBRID CAPITAL SECURITIES RISK. Certain ETFs in which the Fund may invest hold hybrid capital securities. Hybrid capital securities are subject to the risks of equity securities and debt securities. The claims of holders of hybrid capital securities of an issuer are generally subordinated to those of holders of traditional debt securities in bankruptcy, and thus hybrid capital securities may be more volatile and subject to greater risk than traditional debt securities, and may in certain circumstances be even more volatile than traditional equity securities. At the same time, hybrid capital securities may not fully participate in gains of their issuer and thus potential returns of such securities are generally more limited than traditional equity securities, which would participate in such gains. The terms of hybrid capital securities may vary substantially and the risks of a particular hybrid capital security will depend upon the terms of the instrument, but may include the credit risk of the issuer, as well as liquidity risk, since they often are customized to meet the needs of an issuer or a particular investor, and therefore the number of investors that buy such instruments in the secondary market may be small.

INCOME RISK. Certain ETFs in which the Fund may invest hold securities that subject them to income risk. An underlying ETF’s income may decline when interest rates fall or if there are defaults in its portfolio. This decline can occur because an underlying ETF may subsequently invest in lower-yielding securities as debt securities in its portfolio mature, are near maturity or are called, or the underlying ETF otherwise needs to purchase additional debt securities.

INDEX PROVIDER RISK. There is no assurance that the Index Provider, or any agents that act on its behalf, will compile the Index accurately, or that the Index will be determined, maintained, constructed, reconstituted, rebalanced, composed, calculated or disseminated accurately. The Index Provider and its agents do not provide any representation or warranty in relation to the quality, accuracy or completeness of data in the Index, and do not guarantee that the Index will be calculated in accordance with its stated methodology. The Advisor’s mandate as described in this prospectus is to manage the Fund consistently with the Index provided by the Index Provider. The Advisor relies upon the Index provider and its agents to accurately compile, maintain, construct, reconstitute, rebalance, compose, calculate and disseminate the Index accurately. Therefore, losses or costs associated with any Index Provider or agent errors generally will be borne by the Fund and its shareholders. To correct any such error, the Index Provider or its agents may carry out an unscheduled rebalance of the Index or other modification of Index constituents or weightings. When the Fund in turn rebalances its portfolio, any transaction costs and market exposure arising from such portfolio rebalancing will be borne by the Fund and its shareholders. Unscheduled rebalances also expose the Fund to additional tracking error risk. Errors in respect of the quality, accuracy and completeness of the data used to compile the Index may occur from time to time and may not be identified and corrected by the Index Provider for a period of time or at all, particularly where the Index is less commonly used as a benchmark by funds or advisors. For example, during a period where the Index contains incorrect constituents, the Fund tracking the Index would have market exposure to such constituents and would be underexposed to the Index’s other constituents. Such errors may negatively impact the Fund and its shareholders. The Index Provider and its agents rely on various sources of information to assess the criteria of issuers included in the Index, including information that may be based on assumptions and estimates. Neither the Fund nor the Advisor can offer assurances that the Index’s calculation methodology or sources of information will provide an accurate assessment of included issuers.

INDEX REBALANCE RISK. Pursuant to the methodology that the Index Provider uses to calculate and maintain the Index, the Fund may own a significant number of the outstanding shares of underlying ETFs included in the Fund. Any such underlying ETF may be removed from the Index in the event that it does not comply with the eligibility requirements of the Index. As a result, the Fund may be forced to sell shares of certain underlying ETFs at inopportune times or for prices other than at current market values or may elect not to sell such shares on the day that they are removed from the Index, due to market conditions or otherwise. Due to these factors, the variation between the Fund’s annual return and the return of the Index may increase significantly. Apart from scheduled rebalances, the Index Provider may carry out additional ad hoc rebalances to the Index to, for example, correct an error in the selection of

constituents. When the Fund in turn rebalances its portfolio, any transaction costs and market exposure arising from such portfolio rebalancing will be borne by the Fund and its shareholders. Unscheduled rebalances may also expose the Fund to additional tracking error risk. Therefore, errors and additional ad hoc rebalances carried out by the Index Provider may increase the Fund’s costs and market exposure.

INFLATION RISK. Certain ETFs in which the Fund may invest hold securities that subject them to inflation risk. Inflation risk is the risk that the value of assets or income from investments will be less in the future as inflation decreases the value of money. As inflation increases, the present value of an underlying ETF’s assets and distributions may decline.

INTEREST RATE RISK. Certain ETFs in which the Fund may invest hold securities that subject them to interest rate risk. Interest rate risk is the risk that the value of the debt securities in an underlying ETF’s portfolio will decline because of rising market interest rates. Interest rate risk is generally lower for shorter term debt securities and higher for longer-term debt securities. An underlying ETF may be subject to a greater risk of rising interest rates than would normally be the case due to the current period of historically low rates and the effect of potential government fiscal policy initiatives and resulting market reaction to those initiatives. Duration is a reasonably accurate measure of a debt security’s price sensitivity to changes in interest rates and a common measure of interest rate risk. Duration measures a debt security’s expected life on a present value basis, taking into account the debt security’s yield, interest payments and final maturity. In general, duration represents the expected percentage change in the value of a security for an immediate 1% change in interest rates. For example, the price of a debt security with a three-year duration would be expected to drop by approximately 3% in response to a 1% increase in interest rates. Therefore, prices of debt securities with shorter durations tend to be less sensitive to interest rate changes than debt securities with longer durations. As the value of a debt security changes over time, so will its duration.

LEVERAGE RISK. Certain ETFs in which the Fund may invest utilize leverage. Leverage may result in losses that exceed the amount originally invested and may accelerate the rates of losses. Leverage tends to magnify, sometimes significantly, the effect of any increase or decrease in an underlying ETF’s exposure to an asset or class of assets and may cause the value of the underlying ETF’s shares to be volatile and sensitive to market swings.

LIBOR RISK. Certain ETFs in which the Fund may invest hold floating or variable rate obligations that use the London Interbank Offered Rate ("LIBOR") as a reference interest rate. In 2017, the United Kingdom’s Financial Conduct Authority announced that LIBOR will cease to be available for use after 2021. The unavailability or replacement of LIBOR may affect the value, liquidity or return on certain underlying ETF investments and may result in costs incurred in connection with closing out positions and entering into new trades. Any potential effects of the transition away from LIBOR on an underlying ETF or on certain instruments in which an underlying ETF invests can be difficult to ascertain, and they may vary depending on a variety of factors. Any such effects of the transition away from LIBOR, as well as other unforeseen effects, could result in losses to an underlying ETF.

LIQUIDITY RISK. The Fund, and certain underlying ETFs, may hold certain investments that may be subject to restrictions on resale, trade over-the-counter or in limited volume, or lack an active trading market. Accordingly, the Fund, and certain underlying ETFs, may not be able to sell or close out of such investments at favorable times or prices (or at all), or at the prices approximating those at which the Fund currently values them. Illiquid securities may trade at a discount from comparable, more liquid investments and may be subject to wide fluctuations in market value.

MARKET MAKER RISK. The Fund faces numerous market trading risks, including the potential lack of an active market for Fund shares due to a limited number of market markers. Decisions by market makers or authorized participants to reduce their role or step away from these activities in times of market stress could inhibit the effectiveness of the arbitrage process in maintaining the relationship between the underlying values of the Fund’s portfolio securities and the Fund’s market price. The Fund may rely on a small number of third-party market makers to provide a market for the purchase and sale of shares. Any trading halt or other problem relating to the trading activity of these market makers could result in a dramatic change in the spread between the Fund’s net asset value and the price at which the Fund’s shares are trading on the Exchange, which could result in a decrease in value of the Fund’s shares. This reduced effectiveness could result in Fund shares trading at a discount to net asset value and also in greater than normal intraday bid-ask spreads for Fund shares.

MARKET RISK. Market risk is the risk that a particular security, or shares of the Fund in general, may fall in value. Securities are subject to market fluctuations caused by such factors as economic, political, regulatory or market developments, changes in interest rates and perceived trends in securities prices. Shares of the Fund could decline in value or underperform other investments. In addition, local, regional or global events such as war, acts of terrorism, spread of infectious diseases or other public health issues, recessions, or other events could have a significant negative impact on the Fund and its investments. Such events may affect certain geographic regions, countries, sectors and industries more significantly than others. Such events could adversely affect the prices and liquidity of the Fund’s portfolio securities or other instruments and could result in disruptions in the trading markets. Any of such circumstances could have a materially negative impact on the value of the Fund’s shares and result in increased market volatility. During any such events, the Fund’s shares may trade at increased premiums or discounts to their net asset value.

MOMENTUM INVESTING RISK. The Fund employs a “momentum” style of investing that emphasizes selecting stocks that have had higher recent price performance compared to other stocks. Momentum can change quickly and stocks that previously exhibited high

momentum characteristics may not experience positive momentum or may experience more volatility than the market as a whole. In addition, there may be periods when the momentum style of investing is out of favor and the investment performance of the Fund may suffer.

MORTGAGE-RELATED SECURITIES RISK. Certain ETFs in which the Fund may invest hold mortgage-related securities. Mortgage-related securities are subject to the same risks as investments in other types of debt securities, including credit risk, interest rate risk, liquidity risk and valuation risk. However, these investments make an underlying ETF more susceptible to adverse economic, political or regulatory events that affect the value of real estate. Mortgage-related securities are also significantly affected by the rate of prepayments and modifications of the mortgage loans underlying those securities, as well as by other factors such as borrower defaults, delinquencies, realized or liquidation losses and other shortfalls. Mortgage-related securities are particularly sensitive to prepayment risk, given that the term to maturity for mortgage loans is generally substantially longer than the expected lives of those securities. As the timing and amount of prepayments cannot be accurately predicted, the timing of changes in the rate of prepayments of the mortgage loans may significantly affect an underlying ETF's actual yield to maturity on any mortgage-related securities. Along with prepayment risk, mortgage-related securities are significantly affected by interest rate risk.

MUNICIPAL SECURITIES RISK. Certain ETFs in which the Fund may invest hold municipal securities. Issuers, including governmental issuers, may be unable to pay their obligations as they come due. The values of municipal securities that depend on a specific revenue source to fund their payment obligations may fluctuate as a result of actual or anticipated changes in the cash flows generated by the revenue source or changes in the priority of the municipal obligation to receive the cash flows generated by the revenue source. The values of municipal securities held by an underlying ETF may be adversely affected by local political and economic conditions and developments. Adverse conditions in an industry significant to a local economy could have a correspondingly adverse effect on the financial condition of local issuers. In addition, income from municipal securities held by an underlying ETF could be declared taxable because of, among other things, unfavorable changes in tax laws, adverse interpretations by the Internal Revenue Service or state tax authorities, or noncompliant conduct of an issuer or other obligated party. Loss of tax-exempt status may cause interest received and distributed to shareholders by an underlying ETF to be taxable and may result in a significant decline in the values of such municipal securities.

NON-CORRELATION RISK. The Fund’s return may not match the return of the Index for a number of reasons. The Fund incurs operating expenses not applicable to the Index, and may incur costs in buying and selling securities, especially when rebalancing the Fund’s portfolio holdings to reflect changes in the composition of the Index. In addition, the Fund’s portfolio holdings may not exactly replicate the securities included in the Index or the ratios between the securities included in the Index.

NON-DIVERSIFICATION RISK. The Fund is classified as “non-diversified” under the 1940 Act. As a result, the Fund is only limited as to the percentage of its assets which may be invested in the securities of any one issuer by the diversification requirements imposed by the Internal Revenue Code of 1986, as amended. The Fund may invest a relatively high percentage of its assets in a limited number of issuers. As a result, the Fund may be more susceptible to a single adverse economic or regulatory occurrence affecting one or more of these issuers, experience increased volatility and be highly invested in certain issuers.

NON-U.S. SECURITIES RISK. Certain ETFs in which the Fund may invest hold non-U.S. securities. Non-U.S. securities are subject to higher volatility than securities of domestic issuers due to possible adverse political, social or economic developments, restrictions on foreign investment or exchange of securities, capital controls, lack of liquidity, currency exchange rates, excessive taxation, government seizure of assets, the imposition of sanctions by foreign governments, different legal or accounting standards, and less government supervision and regulation of securities exchanges in foreign countries.

PASSIVE INVESTMENT RISK. The Fund is not actively managed. The Fund invests in securities included in or representative of the Index regardless of investment merit. The Fund generally will not attempt to take defensive positions in declining markets. In the event that the Index is no longer calculated, the Index license is terminated or the identity or character of the Index is materially changed, the Fund will seek to engage a replacement index.

PORTFOLIO TURNOVER RISK. High portfolio turnover may result in the Fund paying higher levels of transaction costs and may generate greater tax liabilities for shareholders. Portfolio turnover risk may cause the Fund’s performance to be less than expected.

PREFERRED SECURITIES RISK. Certain ETFs in which the Fund may invest hold preferred securities. Preferred securities combine some of the characteristics of both common stocks and bonds. Preferred securities are typically subordinated to bonds and other debt securities in a company’s capital structure in terms of priority to corporate income, subjecting them to greater credit risk than those debt securities. Generally, holders of preferred securities have no voting rights with respect to the issuing company unless preferred dividends have been in arrears for a specified number of periods, at which time the preferred security holders may obtain limited rights. In certain circumstances, an issuer of preferred securities may defer payment on the securities and, in some cases, redeem the securities prior to a specified date. Preferred securities may also be substantially less liquid than other securities, including common stock.

PREMIUM/DISCOUNT RISK. The market price of the Fund’s shares will generally fluctuate in accordance with changes in the Fund’s net asset value as well as the relative supply of and demand for shares on the Exchange. The Fund’s investment advisor cannot predict whether shares will trade below, at or above their net asset value because the shares trade on the Exchange at market prices and not at net asset value. Price differences may be due, in large part, to the fact that supply and demand forces at work in the secondary

trading market for shares will be closely related, but not identical, to the same forces influencing the prices of the holdings of the Fund trading individually or in the aggregate at any point in time. However, given that shares can only be purchased and redeemed in Creation Units, and only to and from broker-dealers and large institutional investors that have entered into participation agreements (unlike shares of closed-end funds, which frequently trade at appreciable discounts from, and sometimes at premiums to, their net asset value), the Fund’s investment advisor believes that large discounts or premiums to the net asset value of shares should not be sustained. During stressed market conditions, the market for the Fund’s shares may become less liquid in response to deteriorating liquidity in the market for the Fund’s underlying portfolio holdings, which could in turn lead to differences between the market price of the Fund’s shares and their net asset value.

PREPAYMENT RISK. Certain ETFs in which the Fund may invest hold debt securities that subject them to prepayment risk. Prepayment risk is the risk that the issuer of a debt security will repay principal prior to the scheduled maturity date. Debt securities allowing prepayment may offer less potential for gains during a period of declining interest rates, as an underlying ETF may be required to reinvest the proceeds of any prepayment at lower interest rates. These factors may cause the value of an investment in an underlying ETF to change.

SENIOR LOAN RISK. Certain ETFs in which the Fund may invest hold senior loans. Senior loans represent debt obligations of sub-investment grade corporate borrowers, similar to high yield bonds; however, senior loans are different from traditional high yield bonds in that senior loans are typically senior to other obligations of the borrower and generally secured by a lien on all or some portion of the assets of the borrower. The senior loan market has seen a significant increase in loans with weaker lender protections including, but not limited to, limited financial maintenance covenants or, in some cases, no financial maintenance covenants (i.e., “covenant-lite loans”) that would typically be included in a traditional loan agreement and general weakening of other restrictive covenants applicable to the borrower such as limitations on incurrence of additional debt, restrictions on payments of junior debt or restrictions on dividends and distributions. Weaker lender protections such as the absence of financial maintenance covenants in a loan agreement and the inclusion of “borrower-favorable” terms may impact recovery values and/or trading levels of senior loans in the future. The absence of financial maintenance covenants in a loan agreement generally means that the lender may not be able to declare a default if financial performance deteriorates. This may hinder an underlying ETF’s ability to reprice credit risk associated with a particular borrower and reduce an underlying ETF’s ability to restructure a problematic loan and mitigate potential loss. As a result, an underlying ETF’s exposure to losses on investments in senior loans may be increased, especially during a downturn in the credit cycle or changes in market or economic conditions.

Senior loans are also subject to the same risks as investments in other types of debt securities, including credit risk, interest rate risk, liquidity risk and valuation risk that may be heightened because of the limited public information available regarding senior loans. If an underlying ETF holds a senior loan through another financial institution or relies on a financial institution to administer the loan, its receipt of principal and interest on the loan may be subject to the credit risk of that financial institution. Although senior loans are generally secured by specific collateral, there can be no assurance that liquidation of such collateral would satisfy the borrower’s obligation in the event of non-payment of scheduled interest or principal or that such collateral could be readily liquidated.

No active trading market may exist for certain senior loans, which may impair the ability of an underlying ETF to realize full value in the event of the need to sell its position in a senior loan and which may make it difficult to accurately value senior loans. Lastly, senior loans may not be considered “securities,” and an underlying ETF may not be entitled to rely on the anti-fraud protections of the federal securities laws.

SIGNIFICANT EXPOSURE RISK. To the extent that the Fund invests a large percentage of its assets in a single asset class or the securities of issuers within the same country, state, region, industry or sector, an adverse economic, business or political development may affect the value of the Fund’s investments more than if the Fund were more broadly diversified. A significant exposure makes the Fund more susceptible to any single occurrence and may subject the Fund to greater market risk than a fund that is more broadly diversified.

SMALLER COMPANIES RISK. Certain ETFs in which the Fund may invest hold the securities of small and/or mid capitalization companies. Small and/or mid capitalization companies may be more vulnerable to adverse general market or economic developments, and their securities may be less liquid and may experience greater price volatility than larger, more established companies as a result of several factors, including limited trading volumes, fewer products or financial resources, management inexperience and less publicly available information. Accordingly, such companies are generally subject to greater market risk than larger, more established companies.

TRADING ISSUES RISK. Although the shares of the Fund are listed for trading on the Exchange, there can be no assurance that an active trading market for such shares will develop or be maintained. Further, secondary markets may be subject to irregular trading activity and wide bid-ask spreads (which may be especially pronounced for smaller funds). Trading in shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in shares inadvisable. In addition, trading in shares on the Exchange is subject to trading halts caused by extraordinary market volatility pursuant to the Exchange’s “circuit breaker” rules. Market makers are under no obligation to make a market in the Fund’s shares, and authorized participants are not obligated to submit purchase or redemption orders for Creation Units. In the event market makers cease making a market in the Fund's shares or authorized participants stop submitting purchase or redemption orders for Creation Units, Fund shares may trade at a larger premium or discount to their net asset value. There can be no assurance that the requirements of the Exchange necessary to maintain the listing

of the Fund will continue to be met or will remain unchanged. The Fund may have difficulty maintaining its listing on the Exchange in the event the Fund’s assets are small or the Fund does not have enough shareholders.

U.S. GOVERNMENT SECURITIES RISK. Certain ETFs in which the Fund may invest hold U.S. government securities. U.S. government securities are subject to interest rate risk but generally do not involve the credit risks associated with investments in other types of debt securities. As a result, the yields available from U.S. government securities are generally lower than the yields available from other debt securities. U.S. government securities are guaranteed only as to the timely payment of interest and the payment of principal when held to maturity. While securities issued or guaranteed by U.S. federal government agencies (such as Ginnie Mae) are backed by the full faith and credit of the U.S. Department of the Treasury, securities issued by government sponsored entities (such as Fannie Mae and Freddie Mac) are solely the obligation of the issuer and generally do not carry any guarantee from the U.S. government.

VALUATION RISK. Certain ETFs in which the Fund may invest hold debt securities that subject them to valuation risk. Unlike publicly traded securities that trade on national securities exchanges, there is no central place or exchange for trading most debt securities. Debt securities generally trade on an “over-the-counter” market. Due to the lack of centralized information and trading, and variations in lot sizes of certain debt securities, the valuation of debt securities may carry more uncertainty and risk than that of publicly traded securities. Accordingly, determinations of the fair value of debt securities may be based on infrequent and dated information. Also, because the available information is less reliable and more subjective, elements of judgment may play a greater role in valuation of debt securities than for other types of securities.

VOLATILITY RISK. Certain ETFs in which the Fund may invest hold securities that subject them to volatility risk. Volatility is the characteristic of a security, an index or a market to fluctuate significantly in price within a short time period. An underlying ETF may invest in securities or financial instruments that exhibit more volatility than the market as a whole. Such exposures could cause an underlying ETF’s net asset value to experience significant increases or declines in value over short periods of time.

The Fund’s past performance (before and after taxes) is not necessarily an indication of how the Fund will perform in the future.

Returns before taxes do not reflect the effects of any income or capital gains taxes. All after-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of any state or local tax. Returns after taxes on distributions reflect the taxed return on the payment of dividends and capital gains. Returns after taxes on distributions and sale of shares assume you sold your shares at period end, and, therefore, are also adjusted for any capital gains or losses incurred. Returns for the market indices do not include expenses, which are deducted from Fund returns, or taxes.

Your own actual after-tax returns will depend on your specific tax situation and may differ from what is shown here. After-tax returns are not relevant to investors who hold Fund shares in tax-deferred accounts such as individual retirement accounts (IRAs) or employee-sponsored retirement plans.

Portfolio Managers

The Fund’s portfolio is managed by a team (the “Investment Committee”) consisting of:

•	Daniel J. Lindquist, Chairman of the Investment Committee and Managing Director of First Trust
•	Jon C. Erickson, Senior Vice President of First Trust
•	David G. McGarel, Chief Investment Officer, Chief Operating Officer and Managing Director of First Trust
•	Roger F. Testin, Senior Vice President of First Trust
•	Stan Ueland, Senior Vice President of First Trust

The Investment Committee members are primarily and jointly responsible for the day-to-day management of the Fund. Each Investment Committee member has served as a part of the portfolio management team of the Fund since 2018.

Purchase and Sale of Fund Shares

The Fund issues and redeems shares on a continuous basis, at net asset value, only in Creation Units consisting of 50,000 shares. The Fund’s Creation Units are generally issued and redeemed in-kind for securities in which the Fund invests and, in certain circumstances, for cash and only to and from broker-dealers and large institutional investors that have entered into participation agreements. Individual shares of the Fund may only be purchased and sold on Nasdaq and other eligible securities exchanges through a broker-dealer. Shares of the Fund trade on Nasdaq at market prices rather than net asset value, which may cause the shares to trade at a price greater than net asset value (premium) or less than net asset value (discount).

Tax Information

The Fund’s distributions are taxable and will generally be taxed as ordinary income or capital gains. Distributions on shares held in a tax-deferred account, while not immediately taxable, will be subject to tax when the shares are no longer held in a tax-deferred account.

Payments to Broker-Dealers and Other Financial Intermediaries

If you purchase shares of the Fund through a broker-dealer or other financial intermediary (such as a bank), First Trust and First Trust Portfolios L.P., the Fund’s distributor, may pay the intermediary for the sale of Fund shares and related services. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson to recommend the Fund over another investment. Ask your salesperson or visit your financial intermediary’s website for more information.
