PGIM QMA Strategic Alpha Large-Cap Core ETF

SUMMARY: PGIM QMA STRATEGIC ALPHA LARGE-CAP CORE ETF

<b>INVESTMENT OBJECTIVE</b>

The investment objective of the Fund is to seek long-term growth of capital.

<b>FUND FEES AND EXPENSES</b>

The table below describes the fees and expenses that you may pay if you buy and hold shares of the Fund. Investors purchasing shares of the Fund in the secondary market also may be subject to additional costs (including customary brokerage commissions) charged by their broker, which are not reflected in the tables below. The management agreement between PGIM ETF Trust (the Trust) and PGIM Investments LLC (PGIM Investments) (the Management Agreement) provides that PGIM Investments will pay all operating expenses of the Fund, except for certain expenses, including but not limited to, interest expenses, taxes, brokerage expenses, future Rule 12b-1 fees (if any), acquired fund fees and expenses, and the management fee payable to PGIM Investments under the Management Agreement.

<b>Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)</b>

Annual Fund Operating Expenses	PGIM QMA Strategic Alpha Large-Cap Core ETF PGIM QMA Strategic Alpha Large-Cap Core ETF
Management fees	0.17%
Distribution or distribution and service (12b-1) fees	none
Other expenses	none
Total annual Fund operating expenses	0.17%

<b>Example.</b>

The following hypothetical example is intended to help you compare the cost of investing in the Fund with the cost of investing in other exchange traded funds. It assumes that you invest $10,000 in the Fund for the time periods indicated. It assumes a 5% return on your investment each year and that the Fund's operating expenses remain the same. Investors may pay brokerage commissions on their purchases and sales of Fund shares, which are not reflected in the Example. Your actual costs may be higher or lower.

Expense Example	1 Year	3 Years
PGIM QMA Strategic Alpha Large-Cap Core ETF | PGIM QMA Strategic Alpha Large-Cap Core ETF | USD ($)	17	55

Expense Example, No Redemption	1 Year	3 Years
PGIM QMA Strategic Alpha Large-Cap Core ETF | PGIM QMA Strategic Alpha Large-Cap Core ETF | USD ($)	17	55

<b>Portfolio Turnover.</b>

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. The Fund is newly offered; therefore, it does not have a turnover rate for the most recent fiscal year.

<b>INVESTMENTS, RISKS AND PERFORMANCE</b><br/><br/><b>Principal Investment Strategies.</b>

The Fund seeks investments that will appreciate over time. The Fund’s goal is to outperform the returns of the S&P 500 Index over the long term. The Fund normally invests at least 80% of its investable assets in equity and equity-related securities of US large-capitalization companies. The term “investable assets” refers to the Fund’s net assets plus any borrowings for investment purposes. The Fund’s investable assets will be less than its total assets to the extent that it has borrowed money for non-investment purposes, such as to meet anticipated redemptions. The Fund is an actively managed ETF and, thus, does not seek to replicate the performance of a specified index.

QMA employs a proprietary multi-factor quantitatively driven investment process for the Fund. The stock selection process utilizes systematic tools that evaluate stocks based on various signals, such as value, quality and volatility, to differentiate between attractive and unattractive stocks, subject to risk constraints. The investment management team exercises judgment when evaluating underlying data and positions recommended by its quantitative tools.

<b>Principal Risks.</b>

All investments have risks to some degree. An investment in the Fund is not guaranteed to achieve its investment objective; is not a deposit with a bank; is not insured, endorsed or guaranteed by the Federal Deposit Insurance Corporation or any other government agency; and is subject to investment risks, including possible loss of your original investment.

New/Small Fund Risk. The Fund recently commenced operations and has a limited operating history. As a new and relatively small fund, the Fund's performance may not represent how the Fund is expected to or may perform in the long term if and when it becomes larger and has fully implemented its investment strategies. Investment positions may have a disproportionate impact (negative or positive) on performance in new and smaller funds. New and smaller funds may also require a period of time before they are invested in securities that meet their investment objectives and policies and achieve a representative portfolio composition. Since the Fund is new, an active secondary market for the shares of the Fund may not develop or may not continue once developed.

Equity and Equity-Related Securities Risks. The value of a particular security could go down and you could lose money. In addition to an individual security losing value, the value of the equity markets or a sector in which a Fund invests could go down. A Fund's holdings can vary significantly from broad market indexes and the performance of the Fund can deviate from the performance of these indexes. Different parts of a market can react differently to adverse issuer, market, regulatory, political and economic developments.

Large Capitalization Company Risk. Companies with large market capitalizations go in and out of favor based on market and economic conditions. Larger companies tend to be less volatile than companies with smaller market capitalizations. In exchange for this potentially lower risk, the Fund's value may not rise or fall as much as the value of funds that emphasize companies with smaller market capitalizations.

ETF Shares Trading Risk. Once Fund shares are listed for trading on NYSE Arca, Inc. (the Exchange), the shares will be bought and sold in the secondary market at market prices. The market prices of the shares of a Fund are expected to fluctuate in response to changes in a Fund’s NAV, the intraday value of a Fund’s holdings and supply and demand for shares of a Fund. We cannot predict whether shares of a Fund will trade above, below or at their NAV. Trading on the Exchange, including trading of Fund shares, may be halted in certain circumstances and shareholders may not be able to sell Fund shares at the time or price desired. During periods of stressed market conditions, the market for the shares of a Fund may become less liquid in response to deteriorating liquidity in the markets for a Fund’s portfolio investments. This adverse effect on the liquidity of a Fund’s shares could lead to differences between the market price of a Fund's shares and the NAV of those shares. There can be no assurance that the requirements of the Exchange to maintain the listing of shares of a Fund will continue to be met. At times, trading in the securities of ETFs has become volatile and unpredictable and the price of ETF shares has diverged from market driven fundamentals.

Disruptions to creations and redemptions, the existence of significant market volatility or potential lack of an active trading market for the shares of a Fund (including through a trading halt), as well as other factors, may result in a Fund’s shares trading on the Exchange significantly above (at a premium) or below (at a discount) to NAV or to the intraday value of a Fund’s holdings. Premiums and discounts relate to differences between the market price and NAV of a Fund’s shares. During such periods, you may incur significant losses if you sell your shares of a Fund.

The securities held by a Fund may be traded in markets that close at a different time than the Exchange and may trade outside of a collateralized settlement system. Liquidity in those securities may be reduced after the applicable closing times. Accordingly, during the time when the Exchange is open but after the applicable market closing, fixing or settlement times, bid-ask spreads for a Fund’s shares on the Exchange and the corresponding premium or discount between the market price for Fund shares and their NAV may widen. Additionally, during times when the Exchange is open but after the applicable market is closed, there may be changes between the last quote from the closed foreign market and the value of such security during a Fund' s trading day on the Exchange and this may lead to differences between the market price of a Fund's shares and the underlying value of those shares.

Authorized Participant Concentration Risk. Only an authorized participant may engage in creation or redemption transactions directly with a Fund. The Funds have a limited number of intermediaries that act as authorized participants and none of these authorized participants is or will be obligated to engage in creation or redemption transactions. To the extent that these intermediaries exit the business or are unable to or choose not to proceed with creation and/or redemption orders with respect to a Fund and no other authorized participant creates or redeems, shares of the Fund may trade at a substantial discount or premium to NAV, may trade at larger spreads, and possibly face trading halts and/or delisting.

Cost of Buying or Selling Shares. When you buy or sell shares of a Fund through a broker, you will likely incur a brokerage commission or other charges imposed by brokers. In addition, the market price of shares of the Fund, like the price of any exchange-traded security, includes a “bid-ask spread” charged by the market makers or other participants that trade the particular security. The spread of the Fund’s shares varies over time based on the Fund’s trading volume, the spread of the Fund’s underlying securities, and market liquidity and may increase if the Fund’s trading volume, the spread of the Fund’s underlying securities, or market liquidity decreases. In times of severe market disruption, including when trading of the Fund’s holdings may be halted, the bid-ask spread may increase significantly. This means that the shares may trade at a discount to the Fund’s NAV, and the discount is likely to be greatest during significant market volatility.

No Guarantee of Active Trading Market Risk. While shares of a Fund are listed on the Exchange, there can be no assurance that active trading markets for the shares will develop or be maintained by market makers or by authorized participants. The distributor of the Fund’s shares does not maintain a secondary market in the shares.

Model Design and Implementation Risks. The design of QMA's underlying models may be flawed or incomplete. These models are based on historical and theoretical underpinnings that QMA believes are sound, but there is no guarantee that these underpinnings will correlate with security price behavior in the manner assumed by the models or that the quantitative techniques that underlie QMA's portfolio construction processes will fully anticipate important risks. In addition, it is impossible to eliminate completely the risk of error in the implementation of the models that guide QMA's quantitative investment processes, and it may be difficult to implement model recommendations in volatile and rapidly changing market conditions.

Management Risk. The value of your investment may decrease if judgments by the subadviser about the attractiveness, value or market trends affecting a particular security, industry or sector or about market movements are incorrect.

Market Risk. Securities markets may be volatile and the market prices of the Fund’s securities may decline. Securities fluctuate in price based on changes in an issuer’s financial condition and overall market and economic conditions. If the market prices of the securities owned by the Fund fall, the value of your investment in the Fund will decline.

Risk of Increase in Expenses. Your actual cost of investing in a Fund may be higher than the expenses shown in the expense table for a variety of reasons.

<b>Performance.</b>

The Fund has not been in operation for a full calendar year, and hence has no past performance data to present. A number of factors—including risk—can affect how the Fund will perform in the future.

The following hypothetical example is intended to help you compare the cost of investing in the Fund with the cost of investing in other exchange traded funds. It assumes that you invest $10,000 in the Fund for the time periods indicated. It assumes a 5% return on your investment each year and that the Fund's operating expenses remain the same. Investors may pay brokerage commissions on their purchases and sales of Fund shares, which are not reflected in the Example. Your actual costs may be higher or lower.

<b>Portfolio Turnover.</b>

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. The Fund is newly offered; therefore, it does not have a turnover rate for the most recent fiscal year.

<b>INVESTMENTS, RISKS AND PERFORMANCE</b><br/><br/><b>Principal Investment Strategies.</b>

The Fund seeks investments that will appreciate over time. The Fund’s goal is to outperform the returns of the Russell 2000 Growth Index over the long term. The Fund normally invests at least 80% of its investable assets in equity and equity-related securities of US small-capitalization companies. The term “investable assets” refers to the Fund’s net assets plus any borrowings for investment purposes. The Fund’s investable assets will be less than its total assets to the extent that it has borrowed money for non-investment purposes, such as to meet anticipated redemptions. The Fund is an actively managed ETF and, thus, does not seek to replicate the performance of a specified index.

QMA employs a proprietary multi-factor quantitatively driven investment process for the Fund. The stock selection process utilizes systematic tools that evaluate stocks based on various signals, such as value, quality and volatility, to differentiate between attractive and unattractive stocks, subject to risk constraints. The investment management team exercises judgment when evaluating underlying data and positions recommended by its quantitative tools.

<b>Principal Risks.</b>

All investments have risks to some degree. An investment in the Fund is not guaranteed to achieve its investment objective; is not a deposit with a bank; is not insured, endorsed or guaranteed by the Federal Deposit Insurance Corporation or any other government agency; and is subject to investment risks, including possible loss of your original investment.

New/Small Fund Risk. The Fund recently commenced operations and has a limited operating history. As a new and relatively small fund, the Fund's performance may not represent how the Fund is expected to or may perform in the long term if and when it becomes larger and has fully implemented its investment strategies. Investment positions may have a disproportionate impact (negative or positive) on performance in new and smaller funds. New and smaller funds may also require a period of time before they are invested in securities that meet their investment objectives and policies and achieve a representative portfolio composition. Since the Fund is new, an active secondary market for the shares of the Fund may not develop or may not continue once developed.

Equity and Equity-Related Securities Risks. The value of a particular security could go down and you could lose money. In addition to an individual security losing value, the value of the equity markets or a sector in which a Fund invests could go down. A Fund's holdings can vary significantly from broad market indexes and the performance of the Fund can deviate from the performance of these indexes. Different parts of a market can react differently to adverse issuer, market, regulatory, political and economic developments.

Small Company Risk. Small company stocks present above-average risks in comparison to larger companies. Small companies usually offer a smaller range of products and services than larger companies. Smaller companies may also have limited financial resources and may lack management depth. As a result, stocks issued by smaller companies may be less liquid and fluctuate in value more than the stocks of larger, more established companies.

Growth Style Risk. The Fund's growth style may subject the Fund to above-average fluctuations as a result of seeking higher than average capital growth. Historically, growth stocks have performed best during later stages of economic expansion and value stocks have performed best during periods of economic recovery. Since the Fund follows a growth investment style, there is the risk that the growth investment style may be out of favor for a period of time. At times when the style is out of favor, the Fund may underperform the market in general, its benchmark and other mutual funds.

ETF Shares Trading Risk. Once Fund shares are listed for trading on NYSE Arca, Inc. (the Exchange), the shares will be bought and sold in the secondary market at market prices. The market prices of the shares of a Fund are expected to fluctuate in response to changes in a Fund’s NAV, the intraday value of a Fund’s holdings and supply and demand for shares of a Fund. We cannot predict whether shares of a Fund will trade above, below or at their NAV. Trading on the Exchange, including trading of Fund shares, may be halted in certain circumstances and shareholders may not be able to sell Fund shares at the time or price desired. During periods of stressed market conditions, the market for the shares of a Fund may become less liquid in response to deteriorating liquidity in the markets for a Fund’s portfolio investments. This adverse effect on the liquidity of a Fund’s shares could lead to differences between the market price of a Fund's shares and the NAV of those shares. There can be no assurance that the requirements of the Exchange to maintain the listing of shares of a Fund will continue to be met. At times, trading in the securities of ETFs has become volatile and unpredictable and the price of ETF shares has diverged from market driven fundamentals.

Disruptions to creations and redemptions, the existence of significant market volatility or potential lack of an active trading market for the shares of a Fund (including through a trading halt), as well as other factors, may result in a Fund’s shares trading on the Exchange significantly above (at a premium) or below (at a discount) to NAV or to the intraday value of a Fund’s holdings. Premiums and discounts relate to differences between the market price and NAV of a Fund’s shares. During such periods, you may incur significant losses if you sell your shares of a Fund.

The securities held by a Fund may be traded in markets that close at a different time than the Exchange and may trade outside of a collateralized settlement system. Liquidity in those securities may be reduced after the applicable closing times. Accordingly, during the time when the Exchange is open but after the applicable market closing, fixing or settlement times, bid-ask spreads for a Fund’s shares on the Exchange and the corresponding premium or discount between the market price for Fund shares and their NAV may widen. Additionally, during times when the Exchange is open but after the applicable market is closed, there may be changes between the last quote from the closed foreign market and the value of such security during a Fund' s trading day on the Exchange and this may lead to differences between the market price of a Fund's shares and the underlying value of those shares.

Authorized Participant Concentration Risk. Only an authorized participant may engage in creation or redemption transactions directly with a Fund. The Funds have a limited number of intermediaries that act as authorized participants and none of these authorized participants is or will be obligated to engage in creation or redemption transactions. To the extent that these intermediaries exit the business or are unable to or choose not to proceed with creation and/or redemption orders with respect to a Fund and no other authorized participant creates or redeems, shares of the Fund may trade at a substantial discount or premium to NAV, may trade at larger spreads, and possibly face trading halts and/or delisting.

Cost of Buying or Selling Shares. When you buy or sell shares of a Fund through a broker, you will likely incur a brokerage commission or other charges imposed by brokers. In addition, the market price of shares of the Fund, like the price of any exchange-traded security, includes a “bid-ask spread” charged by the market makers or other participants that trade the particular security. The spread of the Fund’s shares varies over time based on the Fund’s trading volume, the spread of the Fund’s underlying securities, and market liquidity and may increase if the Fund’s trading volume, the spread of the Fund’s underlying securities, or market liquidity decreases. In times of severe market disruption, including when trading of the Fund’s holdings may be halted, the bid-ask spread may increase significantly. This means that the shares may trade at a discount to the Fund’s NAV, and the discount is likely to be greatest during significant market volatility.

No Guarantee of Active Trading Market Risk. While shares of a Fund are listed on the Exchange, there can be no assurance that active trading markets for the shares will develop or be maintained by market makers or by authorized participants. The distributor of the Fund’s shares does not maintain a secondary market in the shares.

Model Design and Implementation Risks. The design of QMA's underlying models may be flawed or incomplete. These models are based on historical and theoretical underpinnings that QMA believes are sound, but there is no guarantee that these underpinnings will correlate with security price behavior in the manner assumed by the models or that the quantitative techniques that underlie QMA's portfolio construction processes will fully anticipate important risks. In addition, it is impossible to eliminate completely the risk of error in the implementation of the models that guide QMA's quantitative investment processes, and it may be difficult to implement model recommendations in volatile and rapidly changing market conditions.

Management Risk. The value of your investment may decrease if judgments by the subadviser about the attractiveness, value or market trends affecting a particular security, industry or sector or about market movements are incorrect.

Market Risk. Securities markets may be volatile and the market prices of the Fund’s securities may decline. Securities fluctuate in price based on changes in an issuer’s financial condition and overall market and economic conditions. If the market prices of the securities owned by the Fund fall, the value of your investment in the Fund will decline.

Real Estate Investment Trust (REIT) Risk. Investing in REITs involves certain unique risks in addition to those risks associated with investing in the real estate industry in general. Equity REITs may be affected by changes in the value of the underlying property owned by the REITs, while mortgage REITs may be affected by the quality of any credit extended. REITs are dependent upon management skills, may not be diversified geographically or by property/mortgage asset type, and are subject to heavy cash flow dependency, default by borrowers and self-liquidation. REITs may be more volatile and/or more illiquid than other types of equity securities. REITs (especially mortgage REITs) are subject to interest rate risks. REITs may incur significant amounts of leverage. A Fund will indirectly bear a portion of the expenses, including management fees, paid by each REIT in which it invests, in addition to the expenses of the Fund.

REITs must also meet certain requirements under the Internal Revenue Code of 1986, as amended (the “Code”) to avoid entity level tax and be eligible to pass-through certain tax attributes of their income to shareholders. REITs are consequently subject to the risk of failing to meet these requirements for favorable tax treatment and of failing to maintain their exemptions from registration under the Investment Company Act of 1940. REITs are subject to the risks of changes in the Code affecting their tax status.

Tax reform legislation commonly referred to as the Tax Cuts and Jobs Act (the “Tax Act”) permits a direct REIT shareholder to claim a 20% “qualified business income” deduction for ordinary REIT dividends, but does not permit a regulated investment company (such as the Fund) paying dividends attributable to such income to pass through this special treatment to its shareholders. Unless future legislation or regulatory guidance provides for a pass-through, investors in such a regulated investment company will treat such distributions as ordinary dividend income, as under prior law, whereas a direct REIT investor would benefit from the special treatment.

Illiquid Securities Risk. The Fund may invest in instruments that trade in lower volumes and may make investments that may be less liquid than other investments. Liquidity risk exists when particular investments made by the Fund are difficult to purchase or sell. The Fund may make investments that may become less liquid in response to market developments or adverse investor perceptions. If the Fund is forced to sell these investments to pay redemption proceeds or for other reasons, the Fund may lose money. In addition, when there is no willing buyer and investments cannot be readily sold at the desired time or price, the Fund may have to accept a lower price or may not be able to sell the instrument at all. An inability to sell a portfolio position can adversely affect the Fund’s value or prevent the Fund from being able to take advantage of other investment opportunities.

Risk of Increase in Expenses. Your actual cost of investing in a Fund may be higher than the expenses shown in the expense table for a variety of reasons.

<b>Performance.</b>

The Fund has not been in operation for a full calendar year, and hence has no past performance data to present. A number of factors—including risk—can affect how the Fund will perform in the future.

<b>Portfolio Turnover.</b>

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. The Fund is newly offered; therefore, it does not have a turnover rate for the most recent fiscal year.

<b>INVESTMENTS, RISKS AND PERFORMANCE </b><br/><br/> <b>Principal Investment Strategies.</b>

The Fund seeks investments that will appreciate over time. The Fund’s goal is to outperform the returns of the Russell 2000 Value Index over the long term. The Fund normally invests at least 80% of its investable assets in equity and equity-related securities of US small-capitalization companies. The term “investable assets” refers to the Fund’s net assets plus any borrowings for investment purposes. The Fund’s investable assets will be less than its total assets to the extent that it has borrowed money for non-investment purposes, such as to meet anticipated redemptions. The Fund is an actively managed ETF and, thus, does not seek to replicate the performance of a specified index.

QMA employs a proprietary multi-factor quantitatively driven investment process for the Fund. The stock selection process utilizes systematic tools that evaluate stocks based on various signals, such as value, quality and volatility, to differentiate between attractive and unattractive stocks, subject to risk constraints. The investment management team exercises judgment when evaluating underlying data and positions recommended by its quantitative tools.

<b>Principal Risks.</b>

All investments have risks to some degree. An investment in the Fund is not guaranteed to achieve its investment objective; is not a deposit with a bank; is not insured, endorsed or guaranteed by the Federal Deposit Insurance Corporation or any other government agency; and is subject to investment risks, including possible loss of your original investment.

New/Small Fund Risk. The Fund recently commenced operations and has a limited operating history. As a new and relatively small fund, the Fund's performance may not represent how the Fund is expected to or may perform in the long term if and when it becomes larger and has fully implemented its investment strategies. Investment positions may have a disproportionate impact (negative or positive) on performance in new and smaller funds. New and smaller funds may also require a period of time before they are invested in securities that meet their investment objectives and policies and achieve a representative portfolio composition. Since the Fund is new, an active secondary market for the shares of the Fund may not develop or may not continue once developed.

Equity and Equity-Related Securities Risks. The value of a particular security could go down and you could lose money. In addition to an individual security losing value, the value of the equity markets or a sector in which a Fund invests could go down. A Fund's holdings can vary significantly from broad market indexes and the performance of the Fund can deviate from the performance of these indexes. Different parts of a market can react differently to adverse issuer, market, regulatory, political and economic developments.

Small Company Risk. Small company stocks present above-average risks in comparison to larger companies. Small companies usually offer a smaller range of products and services than larger companies. Smaller companies may also have limited financial resources and may lack management depth. As a result, stocks issued by smaller companies may be less liquid and fluctuate in value more than the stocks of larger, more established companies.

Value Style Risk. Since the Fund follows a value investment style, there is the risk that the value style may be out of favor for a period of time, that the market will not recognize a security's intrinsic value for a long time or that a stock judged to be undervalued may not be undervalued.

ETF Shares Trading Risk. Once Fund shares are listed for trading on NYSE Arca, Inc. (the Exchange), the shares will be bought and sold in the secondary market at market prices. The market prices of the shares of a Fund are expected to fluctuate in response to changes in a Fund’s NAV, the intraday value of a Fund’s holdings and supply and demand for shares of a Fund. We cannot predict whether shares of a Fund will trade above, below or at their NAV. Trading on the Exchange, including trading of Fund shares, may be halted in certain circumstances and shareholders may not be able to sell Fund shares at the time or price desired. During periods of stressed market conditions, the market for the shares of a Fund may become less liquid in response to deteriorating liquidity in the markets for a Fund’s portfolio investments. This adverse effect on the liquidity of a Fund’s shares could lead to differences between the market price of a Fund's shares and the NAV of those shares. There can be no assurance that the requirements of the Exchange to maintain the listing of shares of a Fund will continue to be met. At times, trading in the securities of ETFs has become volatile and unpredictable and the price of ETF shares has diverged from market driven fundamentals.

Disruptions to creations and redemptions, the existence of significant market volatility or potential lack of an active trading market for the shares of a Fund (including through a trading halt), as well as other factors, may result in a Fund’s shares trading on the Exchange significantly above (at a premium) or below (at a discount) to NAV or to the intraday value of a Fund’s holdings. Premiums and discounts relate to differences between the market price and NAV of a Fund’s shares. During such periods, you may incur significant losses if you sell your shares of a Fund.

The securities held by a Fund may be traded in markets that close at a different time than the Exchange and may trade outside of a collateralized settlement system. Liquidity in those securities may be reduced after the applicable closing times. Accordingly, during the time when the Exchange is open but after the applicable market closing, fixing or settlement times, bid-ask spreads for a Fund’s shares on the Exchange and the corresponding premium or discount between the market price for Fund shares and their NAV may widen. Additionally, during times when the Exchange is open but after the applicable market is closed, there may be changes between the last quote from the closed foreign market and the value of such security during a Fund' s trading day on the Exchange and this may lead to differences between the market price of a Fund's shares and the underlying value of those shares.

Authorized Participant Concentration Risk. Only an authorized participant may engage in creation or redemption transactions directly with a Fund. The Funds have a limited number of intermediaries that act as authorized participants and none of these authorized participants is or will be obligated to engage in creation or redemption transactions. To the extent that these intermediaries exit the business or are unable to or choose not to proceed with creation and/or redemption orders with respect to a Fund and no other authorized participant creates or redeems, shares of the Fund may trade at a substantial discount or premium to NAV, may trade at larger spreads, and possibly face trading halts and/or delisting.

Cost of Buying or Selling Shares. When you buy or sell shares of a Fund through a broker, you will likely incur a brokerage commission or other charges imposed by brokers. In addition, the market price of shares of the Fund, like the price of any exchange-traded security, includes a “bid-ask spread” charged by the market makers or other participants that trade the particular security. The spread of the Fund’s shares varies over time based on the Fund’s trading volume, the spread of the Fund’s underlying securities, and market liquidity and may increase if the Fund’s trading volume, the spread of the Fund’s underlying securities, or market liquidity decreases. In times of severe market disruption, including when trading of the Fund’s holdings may be halted, the bid-ask spread may increase significantly. This means that the shares may trade at a discount to the Fund’s NAV, and the discount is likely to be greatest during significant market volatility.

No Guarantee of Active Trading Market Risk. While shares of a Fund are listed on the Exchange, there can be no assurance that active trading markets for the shares will develop or be maintained by market makers or by authorized participants. The distributor of the Fund’s shares does not maintain a secondary market in the shares.

Model Design and Implementation Risks. The design of QMA's underlying models may be flawed or incomplete. These models are based on historical and theoretical underpinnings that QMA believes are sound, but there is no guarantee that these underpinnings will correlate with security price behavior in the manner assumed by the models or that the quantitative techniques that underlie QMA's portfolio construction processes will fully anticipate important risks. In addition, it is impossible to eliminate completely the risk of error in the implementation of the models that guide QMA's quantitative investment processes, and it may be difficult to implement model recommendations in volatile and rapidly changing market conditions.

Management Risk. The value of your investment may decrease if judgments by the subadviser about the attractiveness, value or market trends affecting a particular security, industry or sector or about market movements are incorrect.

Market Risk. Securities markets may be volatile and the market prices of the Fund’s securities may decline. Securities fluctuate in price based on changes in an issuer’s financial condition and overall market and economic conditions. If the market prices of the securities owned by the Fund fall, the value of your investment in the Fund will decline.

Real Estate Investment Trust (REIT) Risk. Investing in REITs involves certain unique risks in addition to those risks associated with investing in the real estate industry in general. Equity REITs may be affected by changes in the value of the underlying property owned by the REITs, while mortgage REITs may be affected by the quality of any credit extended. REITs are dependent upon management skills, may not be diversified geographically or by property/mortgage asset type, and are subject to heavy cash flow dependency, default by borrowers and self-liquidation. REITs may be more volatile and/or more illiquid than other types of equity securities. REITs (especially mortgage REITs) are subject to interest rate risks. REITs may incur significant amounts of leverage. A Fund will indirectly bear a portion of the expenses, including management fees, paid by each REIT in which it invests, in addition to the expenses of the Fund.

REITs must also meet certain requirements under the Internal Revenue Code of 1986, as amended (the “Code”) to avoid entity level tax and be eligible to pass-through certain tax attributes of their income to shareholders. REITs are consequently subject to the risk of failing to meet these requirements for favorable tax treatment and of failing to maintain their exemptions from registration under the Investment Company Act of 1940. REITs are subject to the risks of changes in the Code affecting their tax status.

Tax reform legislation commonly referred to as the Tax Cuts and Jobs Act (the “Tax Act”) permits a direct REIT shareholder to claim a 20% “qualified business income” deduction for ordinary REIT dividends, but does not permit a regulated investment company (such as the Fund) paying dividends attributable to such income to pass through this special treatment to its shareholders. Unless future legislation or regulatory guidance provides for a pass-through, investors in such a regulated investment company will treat such distributions as ordinary dividend income, as under prior law, whereas a direct REIT investor would benefit from the special treatment.

Illiquid Securities Risk. The Fund may invest in instruments that trade in lower volumes and may make investments that may be less liquid than other investments. Liquidity risk exists when particular investments made by the Fund are difficult to purchase or sell. The Fund may make investments that may become less liquid in response to market developments or adverse investor perceptions. If the Fund is forced to sell these investments to pay redemption proceeds or for other reasons, the Fund may lose money. In addition, when there is no willing buyer and investments cannot be readily sold at the desired time or price, the Fund may have to accept a lower price or may not be able to sell the instrument at all. An inability to sell a portfolio position can adversely affect the Fund’s value or prevent the Fund from being able to take advantage of other investment opportunities.

Risk of Increase in Expenses. Your actual cost of investing in a Fund may be higher than the expenses shown in the expense table for a variety of reasons.

<b>Performance.</b>

The Fund has not been in operation for a full calendar year, and hence has no past performance data to present. A number of factors—including risk—can affect how the Fund will perform in the future.

Strategy [Heading]	rr_StrategyHeading	<b>INVESTMENTS, RISKS AND PERFORMANCE </b><br/><br/> <b>Principal Investment Strategies.</b>
Strategy Narrative [Text Block]	rr_StrategyNarrativeTextBlock	The Fund seeks investments that will appreciate over time. The Fund’s goal is to outperform the returns of the Russell 2000 Value Index over the long term. The Fund normally invests at least 80% of its investable assets in equity and equity-related securities of US small-capitalization companies. The term “investable assets” refers to the Fund’s net assets plus any borrowings for investment purposes. The Fund’s investable assets will be less than its total assets to the extent that it has borrowed money for non-investment purposes, such as to meet anticipated redemptions. The Fund is an actively managed ETF and, thus, does not seek to replicate the performance of a specified index. QMA employs a proprietary multi-factor quantitatively driven investment process for the Fund. The stock selection process utilizes systematic tools that evaluate stocks based on various signals, such as value, quality and volatility, to differentiate between attractive and unattractive stocks, subject to risk constraints. The investment management team exercises judgment when evaluating underlying data and positions recommended by its quantitative tools.
Risk [Heading]	rr_RiskHeading	<b>Principal Risks.</b>
Risk Narrative [Text Block]	rr_RiskNarrativeTextBlock	All investments have risks to some degree. An investment in the Fund is not guaranteed to achieve its investment objective; is not a deposit with a bank; is not insured, endorsed or guaranteed by the Federal Deposit Insurance Corporation or any other government agency; and is subject to investment risks, including possible loss of your original investment. New/Small Fund Risk. The Fund recently commenced operations and has a limited operating history. As a new and relatively small fund, the Fund's performance may not represent how the Fund is expected to or may perform in the long term if and when it becomes larger and has fully implemented its investment strategies. Investment positions may have a disproportionate impact (negative or positive) on performance in new and smaller funds. New and smaller funds may also require a period of time before they are invested in securities that meet their investment objectives and policies and achieve a representative portfolio composition. Since the Fund is new, an active secondary market for the shares of the Fund may not develop or may not continue once developed. Equity and Equity-Related Securities Risks. The value of a particular security could go down and you could lose money. In addition to an individual security losing value, the value of the equity markets or a sector in which a Fund invests could go down. A Fund's holdings can vary significantly from broad market indexes and the performance of the Fund can deviate from the performance of these indexes. Different parts of a market can react differently to adverse issuer, market, regulatory, political and economic developments. Small Company Risk. Small company stocks present above-average risks in comparison to larger companies. Small companies usually offer a smaller range of products and services than larger companies. Smaller companies may also have limited financial resources and may lack management depth. As a result, stocks issued by smaller companies may be less liquid and fluctuate in value more than the stocks of larger, more established companies. Value Style Risk. Since the Fund follows a value investment style, there is the risk that the value style may be out of favor for a period of time, that the market will not recognize a security's intrinsic value for a long time or that a stock judged to be undervalued may not be undervalued. ETF Shares Trading Risk. Once Fund shares are listed for trading on NYSE Arca, Inc. (the Exchange), the shares will be bought and sold in the secondary market at market prices. The market prices of the shares of a Fund are expected to fluctuate in response to changes in a Fund’s NAV, the intraday value of a Fund’s holdings and supply and demand for shares of a Fund. We cannot predict whether shares of a Fund will trade above, below or at their NAV. Trading on the Exchange, including trading of Fund shares, may be halted in certain circumstances and shareholders may not be able to sell Fund shares at the time or price desired. During periods of stressed market conditions, the market for the shares of a Fund may become less liquid in response to deteriorating liquidity in the markets for a Fund’s portfolio investments. This adverse effect on the liquidity of a Fund’s shares could lead to differences between the market price of a Fund's shares and the NAV of those shares. There can be no assurance that the requirements of the Exchange to maintain the listing of shares of a Fund will continue to be met. At times, trading in the securities of ETFs has become volatile and unpredictable and the price of ETF shares has diverged from market driven fundamentals.

While shares of a Fund are listed on the Exchange, there can be no assurance that active trading markets for the shares will develop or be maintained by market makers or by authorized participants. The distributor of the Fund’s shares does not maintain a secondary market in the shares. Model Design and Implementation Risks. The design of QMA's underlying models may be flawed or incomplete.

The value of your investment may decrease if judgments by the subadviser about the attractiveness, value or market trends affecting a particular security, industry or sector or about market movements are incorrect.

<b>Portfolio Turnover.</b>

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. The Fund is newly offered; therefore, it does not have a turnover rate for the most recent fiscal year.

<b>INVESTMENTS, RISKS AND PERFORMANCE<br/><br/>Principal Investment Strategies</b>.

The Fund seeks investments that will appreciate over time. The Fund’s goal is to outperform the returns of the MSCI EAFE Index over the long term. Under normal circumstances, the Fund invests at least 80% of its investable assets in equity and equity-related securities of non-US companies. The term “investable assets” refers to the Fund’s net assets plus any borrowings for investment purposes. The Fund’s investable assets will be less than its total assets to the extent that it has borrowed money for non-investment purposes, such as to meet anticipated redemptions. The Fund is an actively managed ETF and, thus, does not seek to replicate the performance of a specified index.

The Fund may invest anywhere in the world, but generally not in US companies. The Fund may invest a large portion of its assets in a single country or region. The Fund will primarily invest in developed markets. The Fund may invest in securities of the issuers of any market capitalization size.

QMA employs a proprietary multi-factor quantitatively driven investment process for the Fund. The stock selection process utilizes systematic tools that evaluate stocks based on various signals, such as value, quality and volatility, to differentiate between attractive and unattractive stocks, subject to risk constraints. The investment management team exercises judgment when evaluating underlying data and positions recommended by its quantitative tools.

<b>Principal Risks.</b>

All investments have risks to some degree. An investment in the Fund is not guaranteed to achieve its investment objective; is not a deposit with a bank; is not insured, endorsed or guaranteed by the Federal Deposit Insurance Corporation or any other government agency; and is subject to investment risks, including possible loss of your original investment.

New/Small Fund Risk. The Fund recently commenced operations and has a limited operating history. As a new and relatively small fund, the Fund's performance may not represent how the Fund is expected to or may perform in the long term if and when it becomes larger and has fully implemented its investment strategies. Investment positions may have a disproportionate impact (negative or positive) on performance in new and smaller funds. New and smaller funds may also require a period of time before they are invested in securities that meet their investment objectives and policies and achieve a representative portfolio composition. Since the Fund is new, an active secondary market for the shares of the Fund may not develop or may not continue once developed.

Equity and Equity-Related Securities Risks. The value of a particular security could go down and you could lose money. In addition to an individual security losing value, the value of the equity markets or a sector in which a Fund invests could go down. A Fund's holdings can vary significantly from broad market indexes and the performance of the Fund can deviate from the performance of these indexes. Different parts of a market can react differently to adverse issuer, market, regulatory, political and economic developments.

Non-US Securities Risk. Investments in securities of non-US issuers (including those denominated in US dollars) generally involve more risk than investing in securities of US issuers. Non-US political, economic and legal systems, especially those in developing and emerging market countries, may be less stable and more volatile than in the US. Non-US legal systems generally have fewer regulatory requirements than the US legal system. In general, less information is publicly available about non-US companies than about US companies. Non-US companies generally are not subject to the same accounting, auditing, and financial reporting standards as are US companies.

Currency Risk. The Fund's net asset value could decline as a result of changes in exchange rates, which could adversely affect the Fund’s investments in currencies, or in securities that trade in, and receive revenues related to, currencies, or in derivatives that provide exposure to currencies. Certain foreign countries may impose restrictions on the ability of issuers of foreign securities to make payment of principal and interest or dividends to investors located outside the country, due to blockage of foreign currency exchanges or otherwise.

Geographic Concentration Risk. The Fund’s performance may be closely tied to the market, economic, political, regulatory or other conditions in the countries or regions in which the Fund invests. This can result in more pronounced risks based upon conditions that impact one or more countries or regions more or less than other countries or regions.

Market Capitalization Risk. The Fund may invest in companies of any market capitalization. Generally, the stock prices of small- and medium-sized companies are less stable than the prices of large company stocks and may present greater risks. Large capitalization companies as a group could fall out of favor with the market, causing the Fund to underperform compared to investments that focus on smaller capitalized companies.

ETF Shares Trading Risk. Once Fund shares are listed for trading on NYSE Arca, Inc. (the Exchange), the shares will be bought and sold in the secondary market at market prices. The market prices of the shares of a Fund are expected to fluctuate in response to changes in a Fund’s NAV, the intraday value of a Fund’s holdings and supply and demand for shares of a Fund. We cannot predict whether shares of a Fund will trade above, below or at their NAV. Trading on the Exchange, including trading of Fund shares, may be halted in certain circumstances and shareholders may not be able to sell Fund shares at the time or price desired. During periods of stressed market conditions, the market for the shares of a Fund may become less liquid in response to deteriorating liquidity in the markets for a Fund’s portfolio investments. This adverse effect on the liquidity of a Fund’s shares could lead to differences between the market price of a Fund's shares and the NAV of those shares. There can be no assurance that the requirements of the Exchange to maintain the listing of shares of a Fund will continue to be met. At times, trading in the securities of ETFs has become volatile and unpredictable and the price of ETF shares has diverged from market driven fundamentals.

Disruptions to creations and redemptions, the existence of significant market volatility or potential lack of an active trading market for the shares of a Fund (including through a trading halt), as well as other factors, may result in a Fund’s shares trading on the Exchange significantly above (at a premium) or below (at a discount) to NAV or to the intraday value of a Fund’s holdings. Premiums and discounts relate to differences between the market price and NAV of a Fund’s shares. During such periods, you may incur significant losses if you sell your shares of a Fund.

The securities held by a Fund may be traded in markets that close at a different time than the Exchange and may trade outside of a collateralized settlement system. Liquidity in those securities may be reduced after the applicable closing times. Accordingly, during the time when the Exchange is open but after the applicable market closing, fixing or settlement times, bid-ask spreads for a Fund’s shares on the Exchange and the corresponding premium or discount between the market price for Fund shares and their NAV may widen. Additionally, during times when the Exchange is open but after the applicable market is closed, there may be changes between the last quote from the closed foreign market and the value of such security during a Fund' s trading day on the Exchange and this may lead to differences between the market price of a Fund's shares and the underlying value of those shares.

Authorized Participant Concentration Risk. Only an authorized participant may engage in creation or redemption transactions directly with a Fund. The Funds have a limited number of intermediaries that act as authorized participants and none of these authorized participants is or will be obligated to engage in creation or redemption transactions. To the extent that these intermediaries exit the business or are unable to or choose not to proceed with creation and/or redemption orders with respect to a Fund and no other authorized participant creates or redeems, shares of the Fund may trade at a substantial discount or premium to NAV, may trade at larger spreads, and possibly face trading halts and/or delisting.

Cost of Buying or Selling Shares. When you buy or sell shares of a Fund through a broker, you will likely incur a brokerage commission or other charges imposed by brokers. In addition, the market price of shares of the Fund, like the price of any exchange-traded security, includes a “bid-ask spread” charged by the market makers or other participants that trade the particular security. The spread of the Fund’s shares varies over time based on the Fund’s trading volume, the spread of the Fund’s underlying securities, and market liquidity and may increase if the Fund’s trading volume, the spread of the Fund’s underlying securities, or market liquidity decreases. In times of severe market disruption, including when trading of the Fund’s holdings may be halted, the bid-ask spread may increase significantly. This means that the shares may trade at a discount to the Fund’s NAV, and the discount is likely to be greatest during significant market volatility.

No Guarantee of Active Trading Market Risk. While shares of a Fund are listed on the Exchange, there can be no assurance that active trading markets for the shares will develop or be maintained by market makers or by authorized participants. The distributor of the Fund’s shares does not maintain a secondary market in the shares.

Model Design and Implementation Risks. The design of QMA's underlying models may be flawed or incomplete. These models are based on historical and theoretical underpinnings that QMA believes are sound, but there is no guarantee that these underpinnings will correlate with security price behavior in the manner assumed by the models or that the quantitative techniques that underlie QMA's portfolio construction processes will fully anticipate important risks. In addition, it is impossible to eliminate completely the risk of error in the implementation of the models that guide QMA's quantitative investment processes, and it may be difficult to implement model recommendations in volatile and rapidly changing market conditions.

Management Risk. The value of your investment may decrease if judgments by the subadviser about the attractiveness, value or market trends affecting a particular security, industry or sector or about market movements are incorrect.

Market Risk. Securities markets may be volatile and the market prices of the Fund’s securities may decline. Securities fluctuate in price based on changes in an issuer’s financial condition and overall market and economic conditions. If the market prices of the securities owned by the Fund fall, the value of your investment in the Fund will decline.

Risk of Increase in Expenses. Your actual cost of investing in a Fund may be higher than the expenses shown in the expense table for a variety of reasons.

<b>Performance.</b>

The Fund has not been in operation for a full calendar year, and hence has no past performance data to present. A number of factors—including risk—can affect how the Fund will perform in the future.

Risk/Return [Heading]	rr_RiskReturnHeading	SUMMARY: PGIM QMA STRATEGIC ALPHA INTERNATIONAL EQUITY ETF
Objective [Heading]	rr_ObjectiveHeading	<b>INVESTMENT OBJECTIVE</b>
Objective, Primary [Text Block]	rr_ObjectivePrimaryTextBlock	The investment objective of the Fund is to seek long-term growth of capital.
Expense [Heading]	rr_ExpenseHeading	<b>FUND FEES AND EXPENSES</b>
Expense Narrative [Text Block]	rr_ExpenseNarrativeTextBlock	The table below describes the fees and expenses that you may pay if you buy and hold shares of the Fund. Investors purchasing shares of the Fund in the secondary market also may be subject to additional costs (including customary brokerage commissions) charged by their broker, which are not reflected in the tables below. The management agreement between PGIM ETF Trust (the Trust) and PGIM Investments LLC (PGIM Investments) (the Management Agreement) provides that PGIM Investments will pay all operating expenses of the Fund, except for certain expenses, including but not limited to, interest expenses, taxes, brokerage expenses, future Rule 12b-1 fees (if any), acquired fund fees and expenses, and the management fee payable to PGIM Investments under the Management Agreement.
Operating Expenses Caption [Text]	rr_OperatingExpensesCaption	<b>Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)</b>
Portfolio Turnover [Heading]	rr_PortfolioTurnoverHeading	<b>Portfolio Turnover.</b>
Portfolio Turnover [Text Block]	rr_PortfolioTurnoverTextBlock	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. The Fund is newly offered; therefore, it does not have a turnover rate for the most recent fiscal year.
Expense Exchange Traded Fund Commissions [Text]	rr_ExpenseExchangeTradedFundCommissions	Investors purchasing shares of the Fund in the secondary market also may be subject to additional costs (including customary brokerage commissions) charged by their broker, which are not reflected in the tables below.
Expense Example [Heading]	rr_ExpenseExampleHeading	<b>Example.</b>
Expense Example Narrative [Text Block]	rr_ExpenseExampleNarrativeTextBlock	The following hypothetical example is intended to help you compare the cost of investing in the Fund with the cost of investing in other exchange traded funds. It assumes that you invest $10,000 in the Fund for the time periods indicated. It assumes a 5% return on your investment each year and that the Fund's operating expenses remain the same. Investors may pay brokerage commissions on their purchases and sales of Fund shares, which are not reflected in the Example. Your actual costs may be higher or lower.
Strategy [Heading]	rr_StrategyHeading	<b>INVESTMENTS, RISKS AND PERFORMANCE<br/><br/>Principal Investment Strategies</b>.
Strategy Narrative [Text Block]	rr_StrategyNarrativeTextBlock	The Fund seeks investments that will appreciate over time. The Fund’s goal is to outperform the returns of the MSCI EAFE Index over the long term. Under normal circumstances, the Fund invests at least 80% of its investable assets in equity and equity-related securities of non-US companies. The term “investable assets” refers to the Fund’s net assets plus any borrowings for investment purposes. The Fund’s investable assets will be less than its total assets to the extent that it has borrowed money for non-investment purposes, such as to meet anticipated redemptions. The Fund is an actively managed ETF and, thus, does not seek to replicate the performance of a specified index. The Fund may invest anywhere in the world, but generally not in US companies. The Fund may invest a large portion of its assets in a single country or region. The Fund will primarily invest in developed markets. The Fund may invest in securities of the issuers of any market capitalization size. QMA employs a proprietary multi-factor quantitatively driven investment process for the Fund. The stock selection process utilizes systematic tools that evaluate stocks based on various signals, such as value, quality and volatility, to differentiate between attractive and unattractive stocks, subject to risk constraints. The investment management team exercises judgment when evaluating underlying data and positions recommended by its quantitative tools.
Risk [Heading]	rr_RiskHeading	<b>Principal Risks.</b>
Risk Narrative [Text Block]	rr_RiskNarrativeTextBlock	All investments have risks to some degree. An investment in the Fund is not guaranteed to achieve its investment objective; is not a deposit with a bank; is not insured, endorsed or guaranteed by the Federal Deposit Insurance Corporation or any other government agency; and is subject to investment risks, including possible loss of your original investment. New/Small Fund Risk. The Fund recently commenced operations and has a limited operating history. As a new and relatively small fund, the Fund's performance may not represent how the Fund is expected to or may perform in the long term if and when it becomes larger and has fully implemented its investment strategies. Investment positions may have a disproportionate impact (negative or positive) on performance in new and smaller funds. New and smaller funds may also require a period of time before they are invested in securities that meet their investment objectives and policies and achieve a representative portfolio composition. Since the Fund is new, an active secondary market for the shares of the Fund may not develop or may not continue once developed. Equity and Equity-Related Securities Risks. The value of a particular security could go down and you could lose money. In addition to an individual security losing value, the value of the equity markets or a sector in which a Fund invests could go down. A Fund's holdings can vary significantly from broad market indexes and the performance of the Fund can deviate from the performance of these indexes. Different parts of a market can react differently to adverse issuer, market, regulatory, political and economic developments. Non-US Securities Risk. Investments in securities of non-US issuers (including those denominated in US dollars) generally involve more risk than investing in securities of US issuers. Non-US political, economic and legal systems, especially those in developing and emerging market countries, may be less stable and more volatile than in the US. Non-US legal systems generally have fewer regulatory requirements than the US legal system. In general, less information is publicly available about non-US companies than about US companies. Non-US companies generally are not subject to the same accounting, auditing, and financial reporting standards as are US companies. Currency Risk. The Fund's net asset value could decline as a result of changes in exchange rates, which could adversely affect the Fund’s investments in currencies, or in securities that trade in, and receive revenues related to, currencies, or in derivatives that provide exposure to currencies. Certain foreign countries may impose restrictions on the ability of issuers of foreign securities to make payment of principal and interest or dividends to investors located outside the country, due to blockage of foreign currency exchanges or otherwise. Geographic Concentration Risk. The Fund’s performance may be closely tied to the market, economic, political, regulatory or other conditions in the countries or regions in which the Fund invests. This can result in more pronounced risks based upon conditions that impact one or more countries or regions more or less than other countries or regions. Market Capitalization Risk. The Fund may invest in companies of any market capitalization. Generally, the stock prices of small- and medium-sized companies are less stable than the prices of large company stocks and may present greater risks. Large capitalization companies as a group could fall out of favor with the market, causing the Fund to underperform compared to investments that focus on smaller capitalized companies. ETF Shares Trading Risk. Once Fund shares are listed for trading on NYSE Arca, Inc. (the Exchange), the shares will be bought and sold in the secondary market at market prices. The market prices of the shares of a Fund are expected to fluctuate in response to changes in a Fund’s NAV, the intraday value of a Fund’s holdings and supply and demand for shares of a Fund. We cannot predict whether shares of a Fund will trade above, below or at their NAV. Trading on the Exchange, including trading of Fund shares, may be halted in certain circumstances and shareholders may not be able to sell Fund shares at the time or price desired. During periods of stressed market conditions, the market for the shares of a Fund may become less liquid in response to deteriorating liquidity in the markets for a Fund’s portfolio investments. This adverse effect on the liquidity of a Fund’s shares could lead to differences between the market price of a Fund's shares and the NAV of those shares. There can be no assurance that the requirements of the Exchange to maintain the listing of shares of a Fund will continue to be met. At times, trading in the securities of ETFs has become volatile and unpredictable and the price of ETF shares has diverged from market driven fundamentals. Disruptions to creations and redemptions, the existence of significant market volatility or potential lack of an active trading market for the shares of a Fund (including through a trading halt), as well as other factors, may result in a Fund’s shares trading on the Exchange significantly above (at a premium) or below (at a discount) to NAV or to the intraday value of a Fund’s holdings. Premiums and discounts relate to differences between the market price and NAV of a Fund’s shares. During such periods, you may incur significant losses if you sell your shares of a Fund. The securities held by a Fund may be traded in markets that close at a different time than the Exchange and may trade outside of a collateralized settlement system. Liquidity in those securities may be reduced after the applicable closing times. Accordingly, during the time when the Exchange is open but after the applicable market closing, fixing or settlement times, bid-ask spreads for a Fund’s shares on the Exchange and the corresponding premium or discount between the market price for Fund shares and their NAV may widen. Additionally, during times when the Exchange is open but after the applicable market is closed, there may be changes between the last quote from the closed foreign market and the value of such security during a Fund' s trading day on the Exchange and this may lead to differences between the market price of a Fund's shares and the underlying value of those shares. Authorized Participant Concentration Risk. Only an authorized participant may engage in creation or redemption transactions directly with a Fund. The Funds have a limited number of intermediaries that act as authorized participants and none of these authorized participants is or will be obligated to engage in creation or redemption transactions. To the extent that these intermediaries exit the business or are unable to or choose not to proceed with creation and/or redemption orders with respect to a Fund and no other authorized participant creates or redeems, shares of the Fund may trade at a substantial discount or premium to NAV, may trade at larger spreads, and possibly face trading halts and/or delisting. Cost of Buying or Selling Shares. When you buy or sell shares of a Fund through a broker, you will likely incur a brokerage commission or other charges imposed by brokers. In addition, the market price of shares of the Fund, like the price of any exchange-traded security, includes a “bid-ask spread” charged by the market makers or other participants that trade the particular security. The spread of the Fund’s shares varies over time based on the Fund’s trading volume, the spread of the Fund’s underlying securities, and market liquidity and may increase if the Fund’s trading volume, the spread of the Fund’s underlying securities, or market liquidity decreases. In times of severe market disruption, including when trading of the Fund’s holdings may be halted, the bid-ask spread may increase significantly. This means that the shares may trade at a discount to the Fund’s NAV, and the discount is likely to be greatest during significant market volatility. No Guarantee of Active Trading Market Risk. While shares of a Fund are listed on the Exchange, there can be no assurance that active trading markets for the shares will develop or be maintained by market makers or by authorized participants. The distributor of the Fund’s shares does not maintain a secondary market in the shares. Model Design and Implementation Risks. The design of QMA's underlying models may be flawed or incomplete.
