Risk [Text Block]

Calculation Methodology Risk. The Index relies directly or indirectly 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, the Index Provider, or the Adviser can offer assurances that the Index’s calculation methodology or sources of information will provide an accurate assessment of included components or a correct valuation of securities, nor can they guarantee the availability or timeliness of the production of the Index.

Pacer Trendpilot® US Large Cap ETF | Diversification Risk Member

Prospectus [Line Items]

Risk [Text Block]

Diversification Risk. The Fund is classified as “diversified” under the 1940 Act. However, the Fund may become “non‑diversified” solely as a result of a change in the relative market capitalization or index weighting of one or more constituents of the Index. Operating as “non-diversified” may make the Fund more susceptible to adverse developments affecting any single issuer held in its portfolio and may be more susceptible to greater losses because of these developments.

Risk [Text Block]

Equity Market Risk. The equity securities held in the Fund’s portfolio may experience sudden, unpredictable drops in value or long periods of decline in value. This may occur because of factors that affect securities markets generally or factors affecting specific industries, sectors or companies in which the Fund invests. Common stocks are susceptible to general stock market fluctuations and to volatile increases and decreases in value as market confidence in and perceptions of their issuers change. The Fund’s NAV and market price may fluctuate significantly in response to these and other factors. As a result, an investor could lose money over short or long periods of time.

ETF Risks. The Fund is an ETF and, as a result of an ETF’s structure, is exposed to the following risks:

◦Authorized Participants (“APs”), Market Makers, and Liquidity Providers Concentration Risk. The Fund has a limited number of financial institutions that may act as APs. In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, shares of the Fund may trade at a material discount to NAV and possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions.

◦Costs of Buying or Selling Shares of the Fund. Due to the costs of buying or selling shares of the Fund, including brokerage commissions imposed by brokers and bid/ask spreads, frequent trading of shares of the Fund may significantly reduce investment results and an investment in shares of the Fund may not be advisable for investors who anticipate regularly making small investments.

◦Shares of the Fund May Trade at Prices Other Than NAV. As with all ETFs, shares of the Fund may be bought and sold in the secondary market at market prices. The price of shares of the Fund, like the price of all traded securities, will be subject to factors such as supply and demand, as well as the current value of the Fund’s portfolio holdings. Although it is expected that the market price of the shares of the Fund will approximate the Fund’s NAV, there may be times when the market price of the shares is more than the NAV intra-day (premium)

or less than the NAV intra-day (discount). This risk is heightened in times of market volatility, periods of steep market declines, and periods when there is limited trading activity for shares in the secondary market, in which case such premiums or discounts may be significant. Shares of the Fund will be bought and sold in the secondary market at market prices.

◦Trading. Although shares of the Fund are listed for trading on a national securities exchange, such as Cboe BZX Exchange, Inc. (the “Exchange”), and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that shares of the Fund will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of shares of the Fund may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than shares of the Fund, and this could lead to differences between the market price of the shares of the Fund and the underlying value of those shares.

Pacer Trendpilot® US Large Cap ETF | Fixed Income Risk Member

Prospectus [Line Items]

Risk [Text Block]

Fixed Income Risk. Generally, the value of fixed income securities will change inversely with changes in interest rates. As interest rates rise, the market value of fixed income securities tends to decrease. Conversely, as interest rates fall, the market value of fixed income securities tends to increase. This risk will be greater for long-term securities than for short-term securities. In recent periods, governmental financial regulators, including the U.S. Federal Reserve, have taken steps to increase interest rates. Changes in government intervention may have adverse effects on investments, volatility, and the liquidity of debt markets.

Pacer Trendpilot® US Large Cap ETF | Government Obligations Risk Member

Prospectus [Line Items]

Risk [Text Block]

Government Obligations Risk. The Fund may invest in securities issued by the U.S. government. There can be no guarantee that the United States will be able to meet its payment obligations with respect to such securities. Additionally, market prices and yields of securities supported by the full faith and credit of the U.S. government may decline or be negative for short or long periods of time.

Pacer Trendpilot® US Large Cap ETF | Large-Capitalization Investing Risk Member

Prospectus [Line Items]

Risk [Text Block]

Large-Capitalization Investing Risk. The Fund may invest in the securities of large-capitalization companies. As a result, the Fund’s performance may be adversely affected if securities of large-capitalization companies underperform securities of smaller-capitalization companies or the market as a whole. The securities of large-capitalization companies may be relatively mature compared to smaller companies and therefore subject to slower growth during times of economic expansion.

Pacer Trendpilot® US Large Cap ETF | Passive Investment Risk Member

Prospectus [Line Items]

Risk [Text Block]

Passive Investment Risk. The Fund is not actively managed and the Adviser would not sell a security due to current or projected underperformance of a security, industry or sector, unless that security is removed from the Index or the selling of shares of that security is otherwise required upon a reconstitution of the Index in accordance with the Index methodology. The Fund invests in securities included in the Index regardless of their investment merits. Other than in response to one of the triggers set forth above in accordance with the Index methodology, the Fund does not take defensive positions under any market conditions, including conditions that are adverse to the performance of the Fund.

Pacer Trendpilot® US Large Cap ETF | Tracking Risk Member

Prospectus [Line Items]

Risk [Text Block]

Tracking Risk. The Fund’s return may not track the return of the Index for a number of reasons. For example, the Fund incurs a number of operating expenses not applicable to the Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund’s securities holdings to reflect changes in the composition of the Index. In addition, when the Fund uses a representative sampling approach, the Fund may not be as well correlated with the return of the Index as when the Fund purchases all of the securities in the Index in the proportions in which they are represented in the Index.

Pacer Trendpilot® US Large Cap ETF | Trend Lag Risk Member

Prospectus [Line Items]

Risk [Text Block]

Trend Lag Risk. At least six consecutive trading days will elapse after the S&P 500 first drops below its historical 200-day simple moving average (or conversely, first moves above such average) before the Index will switch from tracking the S&P 500 to 3-Month US Treasury bills (or conversely, from 3-Month US Treasury bills to the S&P 500). As a result, if the S&P 500 is in an overall positive trend, the Index and consequently the Fund may be adversely affected by a downward trend and/or volatility in the S&P 500 for up to six consecutive trading days (or conversely, if the S&P 500 is in an overall negative trend, the Index and consequently the Fund may not benefit from an upward trend and/or volatility in the S&P 500 for up to six consecutive trading days). This lag will be shorter (one business day) under the Special Indicator. Accordingly, the methodology employed by the Index does not eliminate exposure to downward trends and/or volatility in the S&P 500 and does not provide immediate exposure to upward trends and/or volatility in the S&P 500.

As a result, if the NASDAQ-100 is in an overall positive trend, the Index and consequently the Fund may be adversely affected by a downward trend and/or volatility in the NASDAQ-100 for up to six consecutive trading days (or conversely, if the NASDAQ-100 is in an overall negative trend, the Index and consequently the Fund may not benefit from an upward trend and/or volatility in the NASDAQ-100 for up to six consecutive trading days). This lag will be shorter (one business day) under the Special Indicator. Accordingly, the methodology employed by the Index does not eliminate exposure to downward trends and/or volatility in the NASDAQ-100 and does not provide immediate exposure to upward trends and/or volatility in the NASDAQ-100.

Concentration Risk. If the Index concentrates in an industry or group of industries, the Fund’s investments may be concentrated accordingly. In such event, the value of the Fund’s shares may rise and fall more than the value of shares of a fund that invests in securities of companies in a broader range of industries. In addition, at times, an industry or group of industries in which the Fund is concentrated may be out of favor and underperform other industries or groups of industries.

Risk [Text Block]

Non-Diversification Risk. Although the Fund intends to invest in a variety of securities and instruments, the Fund is considered to be non-diversified, which means that it may invest more of its assets in the securities of a single issuer or a smaller number of issuers than if it were a diversified fund. As a result, the Fund may be more exposed to the risks associated with and developments affecting an individual issuer or a smaller number of issuers than a fund that invests more widely. This may increase the Fund’s volatility and cause the performance of a relatively smaller number of issuers to have a greater impact on the Fund’s performance.

Calculation Methodology Risk. The Index relies directly or indirectly 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, the Index Provider, or the Adviser can offer assurances that the Index’s calculation methodology or sources of information will provide an accurate assessment of included components or a correct valuation of securities, nor can they guarantee the availability or timeliness of the production of the Index.

Diversification Risk. The Fund is classified as “diversified” under the 1940 Act. However, the Fund may become “non‑diversified” solely as a result of a change in the relative market capitalization or index weighting of one or more constituents of the Index. Operating as “non-diversified” may make the Fund more susceptible to adverse developments affecting any single issuer held in its portfolio and may be more susceptible to greater losses because of these developments.

Equity Market Risk. The equity securities held in the Fund’s portfolio may experience sudden, unpredictable drops in value or long periods of decline in value. This may occur because of factors that affect securities markets generally or factors affecting specific industries, sectors or companies in which the Fund invests. Common stocks are susceptible to general stock market fluctuations and to volatile increases and decreases in value as market confidence in and perceptions of their issuers change. The Fund’s NAV and market price may fluctuate significantly in response to these and other factors. As a result, an investor could lose money over short or long periods of time.

ETF Risks. The Fund is an ETF and, as a result of an ETF’s structure, is exposed to the following risks:

◦Authorized Participants (“APs”), Market Makers, and Liquidity Providers Concentration Risk. The Fund has a limited number of financial institutions that may act as APs. In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, shares of the Fund may trade at a material discount to NAV and possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions.

◦Costs of Buying or Selling Shares of the Fund. Due to the costs of buying or selling shares of the Fund, including brokerage commissions imposed by brokers and bid/ask spreads, frequent trading of shares of the Fund may significantly reduce investment results and an investment in shares of the Fund may not be advisable for investors who anticipate regularly making small investments.

◦Shares of the Fund May Trade at Prices Other Than NAV. As with all ETFs, shares of the Fund may be bought and sold in the secondary market at market prices. The price of shares of the Fund, like the price of all traded securities, will be subject to factors such as supply and demand, as well as the current value of the Fund’s portfolio holdings. Although it is expected that the market price of the shares of the Fund will approximate the Fund’s NAV, there may be times when the market price of the shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount). This risk is heightened in times of market volatility, periods of steep market declines, and periods when there is limited trading activity for shares in the secondary market, in which case such premiums or discounts may be significant. Because securities held by the Fund trade on foreign exchanges that are closed when the Fund’s primary listing exchange is open, the Fund is likely to experience premiums and discounts greater than those of domestic ETFs.

◦Trading. Although shares of the Fund are listed for trading on a national securities exchange, such as Cboe BZX Exchange, Inc. (the “Exchange”), and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that shares of the Fund will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of shares of the Fund may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than shares of the Fund, and this could lead to differences between the market price of the shares of the Fund and the underlying value of those shares.

Fixed Income Risk. Generally, the value of fixed income securities will change inversely with changes in interest rates. As interest rates rise, the market value of fixed income securities tends to decrease. Conversely, as interest rates fall, the market value of fixed income securities tends to increase. This risk will be greater for long-term securities than for short-term securities. In recent periods, governmental financial regulators, including the U.S. Federal Reserve, have taken steps to increase interest rates. Changes in government intervention may have adverse effects on investments, volatility, and the liquidity of debt markets.

Pacer Trendpilot® European Index ETF | Tracking Risk Member

Prospectus [Line Items]

Risk [Text Block]

Tracking Risk. The Fund’s return may not track the return of the Index for a number of reasons. For example, the Fund incurs a number of operating expenses not applicable to the Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund’s securities holdings to reflect changes in the composition of the Index. In addition, when the Fund uses a representative sampling approach, the Fund may not be as well correlated with the return of the Index as when the Fund purchases all of the securities in the Index in the proportions in which they are represented in the Index. To the extent the Fund calculates its NAV based on fair value prices and the value of the Index is based on securities’ closing prices on local foreign markets (i.e., the value of the Index is not based on fair value prices), the Fund’s ability to track the Index may be adversely affected.

Sector Risk. To the extent the Fund invests more heavily in particular sectors of the economy, its performance will be especially sensitive to developments that significantly affect those sectors.◦Financial Sector Risk. This sector can be significantly affected by changes in interest rates, government regulation, the rate of defaults on corporate, consumer, and government debt, the availability and cost of capital, and fallout from the housing and sub-prime mortgage crisis. Insurance companies, in particular, may be significantly affected by changes in interest rates, catastrophic events, price and market competition, the imposition of premium rate caps, or other changes in government regulation or tax law and/or rate regulation, which may have an adverse impact on their profitability. In recent years, cyber attacks and technology malfunctions and failures have become increasingly frequent in this sector and have caused significant losses.

Changes in currency exchange rates and the relative value of non-U.S. currencies will affect the value of the Fund’s investment and the value of your Fund shares. Currency exchange rates can be very volatile and can change quickly and unpredictably. As a result, the value of an investment in the Fund may change quickly and without warning and you may lose money.

Pacer Trendpilot® European Index ETF | European Investment Risk Member

European Investment Risk. The Fund is more exposed to the economic and political risks of Europe and of the European countries in which it invests than funds whose investments are more geographically diversified. Adverse economic and political events in Europe may cause the Fund’s investments to decline in value. The economies and markets of European countries are often closely connected and interdependent, and events in one country in Europe can have an adverse impact on other European countries. The Fund makes investments in securities of issuers that are domiciled in, or have significant operations in, member countries of the European Union (the “EU”) that are subject to economic and monetary controls that can adversely affect the Fund’s investments. The European financial markets have experienced volatility and adverse trends in recent years and these events have adversely affected the exchange rate of the euro and may continue to significantly affect other European countries. Decreasing imports or exports, changes in governmental or EU regulations on trade, changes in the exchange rate of the euro, the default or threat of default by an EU member country on its sovereign debt, and/or an economic recession in an EU member country may have a significant adverse effect on the economies of EU member countries and their trading partners, including some or all of the European countries in which the Fund invests.

The risks of investing in the United Kingdom (UK) have been heightened as a result of Brexit, the formal steps taken by the United Kingdom to exit the EU, which has resulted in increased volatility and triggered political, economic, and legal uncertainty. Although the UK has formally left the EU, uncertainty remains as to the long-term consequences of Brexit and issuers in the UK may experience lower growth as a result.

Foreign Securities Risk. Investments in non-U.S. securities involve certain risks that may not be present with investments in U.S. securities. For example, investments in non-U.S. securities may be subject to risk of loss due to foreign currency fluctuations or to political or economic instability. Investments in non-U.S. securities also may be subject to withholding or other taxes and may be subject to additional trading, settlement, custodial, and operational risks. These and other factors can make investments in the Fund more volatile and potentially less liquid than other types of investments. Foreign securities held by the Fund may trade on markets that are closed when U.S. markets are open, which may lead to a difference in the value of the Fund and the underlying foreign securities.

Risk [Text Block]

Geographic Concentration Risk. To the extent the Fund invests a significant portion of its assets in the securities of companies of a single country or region, it is more likely to be impacted by events or conditions affecting that country or region. The Index’s, and therefore the Fund’s, heavy equity exposure to two countries (France and Germany) subjects the Fund to a higher degree of country risk than that of more geographically diversified international funds.

•Risks Related to Investing in Germany. The German economy is dependent on trade, with exports accounting for more than one-third of Germany’s output. Therefore, a reduction in spending by Germany’s trade partners on German products and services, or negative changes in any of these countries, may cause an adverse impact on the German economy. Internal factors, such as high unemployment and government regulation of labor markets, also may affect the performance of the German economy. The European financial markets recently have experienced volatility due to concerns about rising government debt levels of several European countries.

•Risks Related to Investing in France. The Fund’s investment in French issuers subjects the Fund to legal, regulatory, political, currency, security, and economic risks specific to France. Concerns regarding the economic outlook for certain EU countries as well as the negative impact of the Russian war in Ukraine continue to constrain growth forecasts across Eurozone countries, including France. As a result, the French economy has experienced significant volatility and adverse trends due to concerns about a prolonged economic downturn and rising government debt levels. The French economy is dependent on agricultural exports, and as a result, is susceptible to fluctuations in demand for agricultural products.

To the extent the Fund calculates its NAV based on fair value prices and the value of the Index is based on securities’ closing prices on local foreign markets (i.e., the value of the Index is not based on fair value prices), the Fund’s ability to track the Index may be adversely affected.

Trend Lag Risk. At least six consecutive trading days will elapse after the S&P Developed Ex-U.S. LargeCap Index first drops below its historical 200-day simple moving average (or conversely, first moves above such average) before the Index will switch from tracking the S&P Developed Ex-U.S. LargeCap Index to 3-Month US Treasury bills (or conversely, from 3-Month US Treasury bills to the S&P Developed Ex-U.S. LargeCap Index ). As a result, if the S&P Developed Ex-U.S. LargeCap Index is in an overall positive trend, the Index and consequently the Fund may be adversely affected by a downward trend and/or volatility in the S&P Developed Ex-U.S. LargeCap Index for up to six consecutive trading days (or conversely, if the S&P Developed Ex-U.S. LargeCap Index is in an overall negative trend, the Index and consequently the Fund may not benefit from an upward trend and/or volatility in the S&P Developed Ex-U.S. LargeCap Index for up to six consecutive trading days). This lag will be shorter (one business day) under the

Special Indicator. Accordingly, the methodology employed by the Index does not eliminate exposure to downward trends and/or volatility in the S&P Developed Ex-U.S. LargeCap Index or provide immediate exposure to upward trends and/or volatility in the S&P Developed Ex-U.S. LargeCap Index.

Mid-Capitalization Investing Risk. The Fund may invest in the securities of mid-capitalization companies. As a result, the Fund’s performance may be adversely affected if securities of mid-capitalization companies underperform securities of other capitalization ranges or the market as a whole. Securities of smaller companies trade in smaller volumes and are often more vulnerable to market volatility than securities of larger companies.

Risk [Text Block]

Currency Exchange Rate Risk. The Fund’s assets may include investments denominated in non-U.S. currencies, such as the euro, or in securities or other assets that provide exposure to such currencies. Changes in currency exchange rates and the relative value of non-U.S. currencies will affect the value of the Fund’s investment and the value of your Fund shares. Currency exchange rates can be very volatile and can change quickly and unpredictably. As a result, the value of an investment in the Fund may change quickly and without warning and you may lose money.

Pacer Trendpilot® International ETF | Foreign Securities Risk Member

Risk [Text Block]

Foreign Securities Risk. Investments in non-U.S. securities involve certain risks that may not be present with investments in U.S. securities. For example, investments in non-U.S. securities may be subject to risk of loss due to foreign currency fluctuations or to political or economic instability. Investments in non-U.S. securities also may be subject to withholding or other taxes and may be subject to additional trading, settlement, custodial, and operational risks. These and other factors can make investments in the Fund more volatile and potentially less liquid than other types of investments. Foreign securities held by the Fund may trade on markets that are closed when U.S. markets are open, which may lead to a difference in the value of the Fund and the underlying foreign securities.

Geographic Concentration Risk. To the extent the Fund invests a significant portion of its assets in the securities of companies of a single country or region, it is more likely to be impacted by events or conditions affecting that country or region.

◦Risks Related to Investing in Japan. The Japanese economy may be subject to considerable degrees of economic, political and social instability, which could have a negative impact on Japanese securities. Japan’s economic growth rate has remained relatively low for an extended period of time and it may remain low in the future. In addition, Japan is subject to the risk of natural disasters, such as earthquakes, volcanoes, typhoons and tsunamis. Additionally, decreasing U.S. imports, new trade regulations, changes in the U.S. dollar exchange rates, a recession in the United States or continued increases in foreclosure rates may have an adverse impact on the economy of Japan. Japan also has few natural resources, and any fluctuation or shortage in the commodity markets could have a negative impact on Japanese securities.

◦Risks Related to Investing in Western Europe. Most developed countries in Western Europe are members of the European Union (“EU”), and many are also members of the European Monetary Union (EMU), which requires compliance with restrictions on inflation rates, deficits, and debt levels. Unemployment in certain European nations is historically high and several countries face significant debt problems. These conditions can significantly affect every country in Europe. The euro is the official currency of the EU. Funds that invest in Europe may have significant exposure to the euro and events affecting the euro. Recent market events affecting several of the EU member countries have adversely affected the sovereign debt issued by those countries, and ultimately may lead

to a decline in the value of the euro. A significant decline in the value of the euro may produce unpredictable effects on trade and commerce generally and could lead to increased volatility in financial markets worldwide.

The UK’s departure from the EU (referred to as “Brexit”) continues to cause significant uncertainty and may adversely impact the financial results and operations of various European companies and economies. The effects of Brexit will largely depend on any agreements the UK makes to retain access to EU markets. Brexit may result in legal and tax uncertainty and divergent national laws and regulations as the UK determines which EU laws to replace or replicate. The UK may be less stable than it has been in recent years and investments in the UK may be more volatile. Additionally, Brexit could lead to global economic uncertainty and result in significant volatility in the global stock markets and currency exchange rate fluctuations. Any of these effects of Brexit, and other consequences that are difficult to predict at this time, could adversely affect the value of the Fund’s investments..

Diversification Risk. The Fund is classified as “diversified” under the 1940 Act. However, the Fund may become “non‑diversified” solely as a result of a change in the relative market capitalization or index weighting of one or more constituents of the Index. Operating as “non-diversified” may make the Fund more susceptible to adverse developments affecting any single issuer held in its portfolio and may be more susceptible to greater losses because of these developments.

Pacer Trendpilot® US Bond ETF | ETF Risks Member

Prospectus [Line Items]

Risk [Text Block]

ETF Risks. The Fund is an ETF and, as a result of an ETF’s structure, is exposed to the following risks:

◦Authorized Participants (“APs”), Market Makers, and Liquidity Providers Concentration Risk. The Fund has a limited number of financial institutions that may act as APs. In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, shares of the Fund may trade at a material discount to NAV and possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions.

◦Cash Redemption Risk. The Fund’s investment strategy may require it to redeem Shares for cash or to otherwise include cash as part of its redemption proceeds. The Fund may be required to sell or unwind portfolio investments to obtain the cash needed to distribute redemption proceeds. This may cause the Fund to recognize a capital gain that it might not have recognized if it had made a redemption in-kind. As a result, the Fund may pay out higher annual capital gain distributions than if the in-kind redemption process was used. ETF shares can only be redeemed in creation units by APs. Individual shareholders may only purchase and sell ETF shares on a secondary market.

◦Costs of Buying or Selling Shares of the Fund. Due to the costs of buying or selling shares of the Fund, including brokerage commissions imposed by brokers and bid/ask spreads, frequent trading of shares of the Fund may significantly reduce investment results and an investment in shares of the Fund may not be advisable for investors who anticipate regularly making small investments.

◦Shares of the Fund May Trade at Prices Other Than NAV. As with all ETFs, shares of the Fund may be bought and sold in the secondary market at market prices. The price of shares of the Fund, like the price of all traded securities, will be subject to factors such as supply and demand, as well as the current value of the Fund’s portfolio holdings. Although it is expected that the market price of the shares of the Fund will approximate the Fund’s NAV, there may be times when the market price of the shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount). This risk is heightened in times of market volatility, periods of steep market declines, and periods when there is limited trading activity for shares in the secondary market, in which

case such premiums or discounts may be significant. Shares of the Fund will be bought and sold in the secondary market at market prices.

◦Trading. Although shares of the Fund are listed for trading on a national securities exchange, such as NYSE Arca, Inc. (the “Exchange”), and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that shares of the Fund will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of shares of the Fund may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than shares of the Fund, and this could lead to differences between the market price of the shares of the Fund and the underlying value of those shares.

Pacer Trendpilot® US Bond ETF | Fixed Income Risk Member

Prospectus [Line Items]

Risk [Text Block]

Fixed Income Risk. Generally, the value of fixed income securities will change inversely with changes in interest rates. As interest rates rise, the market value of fixed income securities tends to decrease. Conversely, as interest rates fall, the market value of fixed income securities tends to increase. This risk will be greater for long-term securities than for short-term securities. In recent periods, governmental financial regulators, including the U.S. Federal Reserve, have taken steps to increase interest rates. Changes in government intervention may have adverse effects on investments, volatility, and the liquidity of debt markets.

◦Call Risk. During periods of falling interest rates, an issuer of a callable bond held by the Fund may “call” or repay the security prior to its stated maturity, and the Fund may have to reinvest the proceeds at lower interest rates, resulting in a decline in the Fund’s income.

◦Credit Risk. Credit risk refers to the possibility that the issuer of a security will not be able to make payments of interest and principal when due. Changes in an issuer’s credit rating or the market’s perception of an issuer’s creditworthiness may also affect the value of an investment in that issuer.

◦Event Risk. Event risk is the risk that corporate issuers may undergo restructurings, such as mergers, leveraged buyouts, takeovers, or similar events financed by increased debt. As a result of the added debt, the credit quality and market value of a company’s bonds and/or other debt securities may decline significantly.

◦Extension Risk. When interest rates rise, certain obligations will be paid off by the obligor more slowly than anticipated, causing the value of these securities to fall.

◦Interest Rate Risk. Generally, the value of fixed income securities will change inversely with changes in interest rates. As interest rates rise, the market value of fixed income securities tends to decrease. Conversely, as interest rates fall, the market value of fixed income securities tends to increase. This risk will be greater for long-term securities than for short-term securities. Changes in government intervention may have adverse effects on investments, volatility, and illiquidity in debt markets.

◦Prepayment Risk. When interest rates fall, certain obligations will be paid off by the obligor more quickly than originally anticipated, and the proceeds may have to be invested in securities with lower yields.

Passive Investment Risk. The Fund is not actively managed and the Adviser would not sell a security due to current or projected underperformance of a security, industry or sector, unless that security is removed from the Index or the selling of shares of that security is otherwise required upon a reconstitution of the Index in accordance with the Index methodology. The Fund invests in securities included in the Index, regardless of their investment merits. The Fund does not take defensive positions under any market conditions, including conditions that are adverse to the performance of the Fund.

Prospectus [Line Items]

Risk [Text Block]

Tracking Risk. The Fund’s return may not track the return of the Index for a number of reasons. For example, the Fund incurs a number of operating expenses not applicable to the Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund’s securities holdings to reflect changes in the composition of the Index. In addition, when the Fund uses a representative sampling approach, the Fund may not be as well correlated with the return of the Index as when the Fund purchases all of the securities in the Index in the proportions in which they are represented in the Index. Additionally, to the extent the high yield market experiences greater volatility or reduced liquidity, the Fund may not be able to acquire or dispose of the high yield securities in the Index at exactly the same time and price reflected in a reconstitution of the Index, and consequently, the Index’s exposure to the iBoxx USD Liquid High Yield Index may result in a greater difference between the returns of the Fund and those of the Index.

As a result, if the iBoxx USD Liquid High Yield Index is in an overall positive trend, the Index and consequently the Fund may be adversely affected by a downward trend and/or volatility in the iBoxx USD Liquid High Yield Index for up to six consecutive trading days (or conversely, if the iBoxx USD Liquid High Yield Index is in an overall negative trend, the Index and consequently the Fund may not benefit from an upward trend and/or volatility in the iBoxx USD Liquid High Yield Index for up to six consecutive trading days). Accordingly, the methodology employed by the Index does not eliminate exposure to downward trends and/or volatility in the iBoxx USD Liquid High Yield Index and does not provide immediate exposure to upward trends and/or volatility in the iBoxx USD Liquid High Yield Index.

High Portfolio Turnover Risk. At times, the Fund may have a portfolio turnover rate substantially greater than 100%.

High Yield Risk. High yield debt obligations (commonly known as “junk bonds”) are speculative investments and entail greater risk of loss of principal than securities and loans that are investment grade rated because of their greater exposure to credit risk. The high yield market at times is subject to substantial volatility and high yield debt obligations may be less liquid than higher quality securities.

Common stocks are susceptible to general stock market fluctuations and to volatile increases and decreases in value as market confidence in and perceptions of their issuers change.

(the “Exchange”), and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that shares of the Fund will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of shares of the Fund may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than shares of the Fund, and this could lead to differences between the market price of the shares of the Fund and the underlying value of those shares.

Risk [Text Block]

Fixed Income Risk. Generally, the value of fixed income securities will change inversely with changes in interest rates. As interest rates rise, the market value of fixed income securities tends to decrease. Conversely, as interest rates fall, the market value of fixed income securities tends to increase. This risk will be greater for long-term securities than for short-term securities. In recent periods, governmental financial regulators, including the U.S. Federal Reserve, have taken steps to increase interest rates. Changes in government intervention may have adverse effects on investments, volatility, and the liquidity of debt markets.

Government Obligations Risk. The Fund may invest in securities issued by the U.S. government. There can be no guarantee that the United States will be able to meet its payment obligations with respect to such securities. Additionally, market prices and yields of securities supported by the full faith and credit of the U.S. government may decline or be negative for short or long periods of time.

Large-Capitalization Investing Risk. The Fund may invest in the securities of large-capitalization companies. As a result, the Fund’s performance may be adversely affected if securities of large-capitalization companies underperform securities of smaller-capitalization companies or the market as a whole. The securities of large-capitalization companies may be relatively mature compared to smaller companies and therefore subject to slower growth during times of economic expansion.

Passive Investment Risk. The Fund is not actively managed and the Adviser would not sell a security due to current or projected underperformance of a security, industry or sector, unless that security is removed from the Index or the selling of shares of that security is otherwise required upon a reconstitution of the Index in accordance with the Index methodology. The Fund invests in securities included in the Index, regardless of their investment merits. The Fund does not take defensive positions under any market conditions, including conditions that are adverse to the performance of the Fund.

Pacer Trendpilot® Fund of Funds ETF | Tracking Risk Member

Prospectus [Line Items]

Risk [Text Block]

Tracking Risk. The Fund’s return may not track the return of the Index for a number of reasons. For example, the Fund incurs a number of operating expenses not applicable to the Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund’s securities holdings to reflect changes in the composition of the Index. In addition, when the Fund uses a representative sampling approach, the Fund may not be as well correlated with the return of the Index as when the Fund purchases all of the securities in the Index in the proportions in which they are represented in the Index. To the extent the Fund calculates its NAV based on fair value prices and the value of the Index is based on securities’ closing prices on local foreign markets (i.e., the value of the Index is not based on fair value prices), the Fund’s ability to track the Index may be adversely affected.

Pacer Trendpilot® Fund of Funds ETF | Trend Lag Risk Member

Prospectus [Line Items]

Risk [Text Block]

Trend Lag Risk. At least six consecutive trading days will elapse after the applicable Equity Component first drops below its historical 200-day simple moving average (or conversely, first moves above such average) before a Trendpilot® Index will switch from tracking the Equity Component to 3-Month US Treasury bills (or conversely, from 3-Month US Treasury bills to the Equity Component). As a result, if the Equity Component is in an overall positive trend, the Trendpilot® Index and consequently the Fund of Funds Index and the Fund may be adversely affected by a downward trend and/or volatility in the Equity Component for up to six consecutive trading days (or conversely, if the Equity Component is in an overall negative trend, the Trendpilot® Index and consequently the Fund of Funds Index and the Fund may not benefit from an upward trend and/or volatility in the Equity Component for up to six consecutive trading days). Accordingly, the methodology employed by each Trendpilot® Index does not eliminate exposure to downward trends and/or volatility in the Equity Component and does not provide immediate exposure to upward trends and/or volatility in the Equity Component.

Securities of smaller companies trade in smaller volumes and are often more vulnerable to market volatility than securities of larger companies.

Risk [Text Block]

Currency Exchange Rate Risk. The Fund’s assets may include exposure to investments denominated in non-U.S. currencies or in securities or other assets that provide exposure to such currencies. Changes in currency exchange rates and the relative value of non-U.S. currencies will affect the value of the Fund’s investment and the value of your Fund shares. Currency exchange rates can be very volatile and can change quickly and unpredictably. As a result, the value of an investment in the Fund may change quickly and without warning and you may lose money.

Pacer Trendpilot® Fund of Funds ETF | Foreign Securities Risk Member

Risk [Text Block]

Foreign Securities Risk. Investments in non-U.S. securities involve certain risks that may not be present with investments in U.S. securities. For example, investments in non-U.S. securities may be subject to risk of loss due to foreign currency fluctuations or to political or economic instability. Investments in non-U.S. securities also may be subject to withholding or other taxes and may be subject to additional trading, settlement, custodial, and operational risks. These and other factors can make investments in the Fund more volatile and potentially less liquid than other types of investments. Foreign securities held by the Fund may trade on markets that are closed when U.S. markets are open, which may lead to a difference in the value of the Fund and the underlying foreign securities.

Other Investment Companies Risk. The Fund primarily invests in other ETFs and will incur higher and duplicative expenses as a result of such investments. There is also the risk that the Fund may suffer losses due to the investment practices of the underlying funds. When the Fund invests in other investment companies, the Fund will be subject to substantially the same risks as those associated with the direct ownership of securities held by such investment companies. Investments in ETFs are also subject to the “ETF Risks” described above.

Pacer Trendpilot® Fund of Funds ETF | High Yield Risk Member

Prospectus [Line Items]

Risk [Text Block]

High Yield Risk. High yield securities (or “junk bonds”) entail greater risk of loss of principal because of their greater exposure to credit risk. High yield debt obligations are speculative investments and may also be less liquid than higher quality securities, and may cause income and principal losses for the Fund. The market for high yield securities is generally thinner and less active than the market for higher quality securities. If there is a “flight to safety,” the market’s perception of “high yield” securities may turn negative, and these types of securities may become classified as “high risk.” Consequently, high yield securities and loans entail greater risk of loss of principal than securities and loans that are investment grade rated. Investment in or exposure to high yield (lower rated) debt instruments (also known as “junk bonds”) may involve greater levels of interest rate, credit, liquidity and valuation risk than for higher rated instruments. High yield debt instruments may be sensitive to economic changes, political changes, or adverse developments specific to a company.

Common stocks are susceptible to general stock market fluctuations and to volatile increases and decreases in value as market confidence in and perceptions of their issuers change.

▪ETF Risks. The Fund is an ETF and, as a result of an ETF’s structure, is exposed to the following risks:

◦Authorized Participants (“APs”), Market Makers, and Liquidity Providers Concentration Risk. The Fund has a limited number of financial institutions that may act as APs. In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, shares of the Fund may trade at a material discount to NAV and possibly face delisting: (i) APs exit the business or

otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions.

◦Costs of Buying or Selling Shares of the Fund. Due to the costs of buying or selling shares of the Fund, including brokerage commissions imposed by brokers and bid/ask spreads, frequent trading of shares of the Fund may significantly reduce investment results and an investment in shares of the Fund may not be advisable for investors who anticipate regularly making small investments.

◦Shares of the Fund May Trade at Prices Other Than NAV. As with all ETFs, shares of the Fund may be bought and sold in the secondary market at market prices. The price of shares of the Fund, like the price of all traded securities, will be subject to factors such as supply and demand, as well as the current value of the Fund’s portfolio holdings. Although it is expected that the market price of the shares of the Fund will approximate the Fund’s NAV, there may be times when the market price of the shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount). This risk is heightened in times of market volatility, periods of steep market declines, and periods when there is limited trading activity for shares in the secondary market, in which case such premiums or discounts may be significant. Shares of the Fund will be bought and sold in the secondary market at market prices.

◦Trading. Although shares of the Fund are listed for trading on a national securities exchange, such as Cboe BZX Exchange, Inc. (the “Exchange”), and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that shares of the Fund will trade with any volume, or at all, on any stock exchange.

◦Authorized Participants (“APs”), Market Makers, and Liquidity Providers Concentration Risk. The Fund has a limited number of financial institutions that may act as APs. In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, shares of the Fund may trade at a material discount to NAV and possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions.

◦Costs of Buying or Selling Shares of the Fund. Due to the costs of buying or selling shares of the Fund, including brokerage commissions imposed by brokers and bid/ask spreads, frequent trading of shares of the Fund may significantly reduce investment results and an investment in shares of the Fund may not be advisable for investors who anticipate regularly making small investments.

◦Shares of the Fund May Trade at Prices Other Than NAV. As with all ETFs, shares of the Fund may be bought and sold in the secondary market at market prices. The price of shares of the Fund, like the price of all traded securities, will be subject to factors such as supply and demand, as well as the current value of the Fund’s portfolio holdings. Although it is expected that the market price of the shares of the Fund will approximate the Fund’s NAV, there may be times when the market price of the shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount). This risk is heightened in times of market volatility, periods of steep market declines, and periods when there is limited trading activity for shares in the secondary market, in which case such premiums or discounts may be significant. Because securities held by the Fund trade on foreign exchanges that are closed when the Fund’s primary listing exchange is open, the Fund is likely to experience premiums and discounts greater than those of domestic ETFs.

◦Trading. Although shares of the Fund are listed for trading on a national securities exchange, such as Cboe BZX Exchange, Inc. (the “Exchange”), and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that shares of the Fund will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of shares of the Fund may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than shares of the Fund, and this could lead to differences between the market price of the shares of the Fund and the underlying value of those shares.

Large-Capitalization Investing Risk. The Fund may invest in the securities of large-capitalization companies. As a result, the Fund’s performance may be adversely affected if securities of large-capitalization companies underperform securities of smaller-capitalization companies or the market as a whole. The securities of large-capitalization companies may be relatively mature compared to smaller companies and therefore subject to slower growth during times of economic expansion.

Risk [Text Block]

Tracking Risk. The Fund’s return may not track the return of the Index for a number of reasons. For example, the Fund incurs a number of operating expenses not applicable to the Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund’s securities holdings to reflect changes in the composition of the Index. In addition, when the Fund uses a representative sampling approach, the Fund may not be as well correlated with the return of the Index as when the Fund purchases all of the securities in the Index in the proportions in which they are represented in the Index. To the extent the Fund calculates its NAV based on fair value prices and the value of the Index is based on securities’ closing prices on local foreign markets (i.e., the value of the Index is not based on fair value prices), the Fund’s ability to track the Index may be adversely affected.

In such event, the value of the Fund’s shares may rise and fall more than the value of shares of a fund that invests in securities of companies in a broader range of industries. In addition, at times, an industry or group of industries in which the Fund is concentrated may be out of favor and underperform other industries or groups of industries.

Pacer Global Cash Cows Dividend ETF | Sector Risk Member

Sector Risk. To the extent the Fund invests more heavily in particular sectors of the economy, its performance will be especially sensitive to developments that significantly affect those sectors.

◦Consumer Staples Sector Risk. The permissibility of using various food additives and production methods, fads, marketing campaigns, and other factors affecting consumer demand is tied closely to the performance of companies in this sector. In particular, tobacco companies may be adversely affected by new laws, regulations, and litigation. The consumer staples sector may also be adversely affected by changes or trends in commodity prices, which may be influenced or characterized by unpredictable factors.

◦Energy Sector Risk. The Fund may invest in companies in the energy sector, and therefore the performance of the Fund could be negatively impacted by events affecting this sector. The profitability of companies in the energy sector is related to worldwide energy prices, exploration, and production spending. The value of securities issued by companies in the energy sector may decline for many reasons, including, among others, changes in energy prices, government regulations, energy conservation efforts, natural disasters, and potential civil liabilities. Such companies are also subject to risks changes in economic conditions, as well as market and political risks of the countries where energy companies are located or do business.

◦Health Care Sector Risk.The Fund may invest in companies in the health care sector, and therefore the performance of the Fund could be negatively impacted by events affecting this sector. Companies in the health care sector are subject to extensive government regulation and their profitability can be significantly affected by restrictions on government reimbursement for medical expenses, rising costs of medical products and services, pricing pressure (including price discounting), limited product lines and an increased emphasis on the delivery of healthcare through outpatient services.

Currency Exchange Rate Risk. The Fund’s assets may include investments denominated in non-U.S. currencies, such as the euro, or in securities or other assets that provide exposure to such currencies. Changes in currency exchange rates and the relative value of non-U.S. currencies will affect the value of the Fund’s investment and the value of your Fund shares. Currency exchange rates can be very volatile and can change quickly and unpredictably. As a result, the value of an investment in the Fund may change quickly and without warning and you may lose money.

Foreign Securities Risk. Investments in non-U.S. securities involve certain risks that may not be present with investments in U.S. securities. For example, investments in non-U.S. securities may be subject to risk of loss due to foreign currency fluctuations or to political or economic instability. Investments in non-U.S. securities also may be subject to withholding or other taxes and may be subject to additional trading, settlement, custodial, and operational risks. These and other factors can make investments in the Fund more volatile and potentially less liquid than other types of investments. Foreign securities held by the Fund may trade on markets that are closed when U.S. markets are open, which may lead to a difference in the value of the Fund and the underlying foreign securities.

Diversification Risk. The Fund is classified as “diversified” under the 1940 Act. However, the Fund may become “non‑diversified” solely as a result of a change in the relative market capitalization or index weighting of one or more constituents of the Index. Operating as “non-diversified” may make the Fund more susceptible to adverse

developments affecting any single issuer held in its portfolio and may be more susceptible to greater losses because of these developments.

Equity Market Risk. The equity securities held in the Fund’s portfolio may experience sudden, unpredictable drops in value or long periods of decline in value. This may occur because of factors that affect securities markets generally or factors affecting specific industries, sectors or companies in which the Fund invests. Common stocks are susceptible to general stock market fluctuations and to volatile increases and decreases in value as market confidence in and perceptions of their issuers change. The Fund’s NAV and market price may fluctuate significantly in response to these and other factors. As a result, an investor could lose money over short or long periods of time.

Risks Related to Investing in Europe. The Fund is more exposed to the economic and political risks of Europe and of the European countries in which it invests than funds whose investments are more geographically diversified.

Adverse economic and political events in Europe may cause the Fund’s investments to decline in value. The economies and markets of European countries are often closely connected and interdependent, and events in one country in Europe can have an adverse impact on other European countries. The Fund makes investments in securities of issuers that are domiciled in, or have significant operations in, member countries of the European Union (the “EU”) that are subject to economic and monetary controls that can adversely affect the Fund’s investments. The European financial markets have experienced volatility and adverse trends in recent years and these events have adversely affected the exchange rate of the euro and may continue to significantly affect other European countries. Decreasing imports or exports, changes in governmental or EU regulations on trade, changes in the exchange rate of the euro, the default or threat of default by an EU member country on its sovereign debt, and/or an economic recession in an EU member country may have a significant adverse effect on the economies of EU member countries and their trading partners, including some or all of the European countries in which the Fund invests.

The risks of investing in the United Kingdom (UK) have been heightened as a result of Brexit, the formal steps taken by the United Kingdom to exit the EU, which has resulted in increased volatility and triggered political, economic, and legal uncertainty. Although the UK has formally left the EU, uncertainty remains as to the long-term consequences of Brexit and issuers in the UK may experience lower growth as a result.

Additionally, decreasing U.S. imports, new trade regulations, changes in the U.S. dollar exchange rates, a recession in the United States or continued increases in foreclosure rates may have an adverse impact on the economy of Japan.

Calculation Methodology Risk. The Index relies directly or indirectly 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, the Index Provider, or the Adviser can offer assurances that the Index’s calculation methodology or sources of information will provide an accurate assessment of included components or a correct valuation of securities, nor can they guarantee the availability or timeliness of the production of the Index.

Diversification Risk. The Fund is classified as “diversified” under the 1940 Act. However, the Fund may become “non‑diversified” solely as a result of a change in the relative market capitalization or index weighting of one or more constituents of the Index. Operating as “non-diversified” may make the Fund more susceptible to adverse developments affecting any single issuer held in its portfolio and may be more susceptible to greater losses because of these developments.

Equity Market Risk. The equity securities held in the Fund’s portfolio may experience sudden, unpredictable drops in value or long periods of decline in value. This may occur because of factors that affect securities markets generally or factors affecting specific industries, sectors or companies in which the Fund invests. Common stocks are susceptible to general stock market fluctuations and to volatile increases and decreases in value as market confidence in and perceptions of their issuers change. The Fund’s NAV and market price may fluctuate significantly in response to these and other factors. As a result, an investor could lose money over short or long periods of time.

Pacer Emerging Markets Cash Cows 100 ETF | ETF Risks Member

Risk [Text Block]

ETF Risks. The Fund is an ETF and, as a result of an ETF’s structure, is exposed to the following risks:

◦Authorized Participants (“APs”), Market Makers, and Liquidity Providers Concentration Risk. The Fund has a limited number of financial institutions that may act as APs. In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, shares of the Fund may trade at a material discount to NAV and possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions.

◦Cash Redemption Risk. The Fund’s investment strategy may require it to redeem Shares for cash or to otherwise include cash as part of its redemption proceeds. The Fund may be required to sell or unwind portfolio investments to obtain the cash needed to distribute redemption proceeds. This may cause the Fund to recognize a capital gain that it might not have recognized if it had made a redemption in-kind. As a result, the Fund may pay out higher annual capital gain distributions than if the in-kind redemption process was used. ETF shares can only be redeemed in creation units by APs. Individual shareholders may only purchase and sell ETF shares on a secondary market.

◦Costs of Buying or Selling Shares of the Fund. Due to the costs of buying or selling shares of the Fund, including brokerage commissions imposed by brokers and bid/ask spreads, frequent trading of shares of the Fund may significantly reduce investment results and an investment in shares of the Fund may not be advisable for investors who anticipate regularly making small investments.

◦Shares of the Fund May Trade at Prices Other Than NAV. As with all ETFs, shares of the Fund may be bought and sold in the secondary market at market prices. The price of shares of the Fund, like the price of all traded securities, will be subject to factors such as supply and demand, as well as the current value of the Fund’s portfolio holdings. Although it is expected that the market price of the shares of the Fund will approximate the Fund’s NAV, there may be times when the market price of the shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount). This risk is heightened in times of market volatility, periods of steep market declines, and periods when there is limited trading activity for shares in the secondary market, in which case such premiums or discounts may be significant. Because securities held by the Fund trade on foreign exchanges that are closed when the Fund’s primary listing exchange is open, the Fund is likely to experience premiums and discounts greater than those of domestic ETFs.

◦Trading. Although shares of the Fund are listed for trading on a national securities exchange, such as the Nasdaq Stock Market LLC (the “Exchange”), and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that shares of the Fund will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of shares of the Fund may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than shares of the Fund, and this could lead to differences between the market price of the shares of the Fund and the underlying value of those shares.

Risk [Text Block]

Tracking Risk. The Fund’s return may not track the return of the Index for a number of reasons. For example, the Fund incurs a number of operating expenses not applicable to the Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund’s securities holdings to reflect changes in the composition of the Index. In addition, when the Fund uses a representative sampling approach, the Fund may not be as well correlated with the return of the Index as when the Fund purchases all of the securities in the Index in the proportions in which they are represented in the Index. To the extent the Fund calculates its NAV based on fair value prices and the value of the Index is based on securities’ closing prices on local foreign markets (i.e., the value of the Index is not based on fair value prices), the Fund’s ability to track the Index may be adversely affected.

The value of stocks of information technology companies and companies that rely heavily on technology is particularly vulnerable to rapid changes in technology product cycles, rapid product obsolescence, government regulation and competition, both domestically and internationally, including competition from foreign competitors with lower production costs. Stocks of information technology companies and companies that rely heavily on technology, especially those of smaller, less-seasoned companies, tend to be more volatile than the overall market.

Foreign Securities Risk. Investments in non-U.S. securities involve certain risks that may not be present with investments in U.S. securities. For example, investments in non-U.S. securities may be subject to risk of loss due to foreign currency fluctuations or to political or economic instability. Investments in non-U.S. securities also may be subject to withholding or other taxes and may be subject to additional trading, settlement, custodial, and operational risks. These and other factors can make investments in the Fund more volatile and potentially less liquid than other types of investments. Foreign securities held by the Fund may trade on markets that are closed when U.S. markets are open, which may lead to a difference in the value of the Fund and the underlying foreign securities.

Geographic Concentration Risk. To the extent the Fund invests a significant portion of its assets in the securities of companies of a single country or region, it is more likely to be impacted by events or conditions affecting that country or region. Because the Index is a subset of the FTSE Emerging Markets Index, the geographic concentrations of the Index, and consequently the Fund, may be different than those of the broader FTSE Emerging Markets Index.

◦Risks Related to Investing in Brazil. Investments in securities of Brazilian companies are subject to regulatory and economic interventions that the Brazilian government has frequently exercised in the past, including the setting of wage and price controls, blocking access to bank accounts, imposing exchange controls and limiting imports. Investments are also subject to certain restrictions on foreign investment as provided by Brazilian law. The Brazilian economy has historically been subject to high rates of inflation and a high level of debt, all of which may stifle economic growth. Despite rapid development in recent years, Brazil still suffers from high levels of corruption, crime and income disparity. There is the possibility that such conditions may lead to social unrest and political upheaval in the future, which may have adverse effects on the Fund’s investments.

◦Risks Related to Investing China. Investing in securities of Chinese companies involves additional risks, including, but not limited to: the economy of China differs, often unfavorably, from the U.S. economy in such respects as structure, general development, government involvement, wealth distribution, rate of inflation, growth rate, allocation of resources and capital reinvestment, among others; the central government has historically exercised substantial control over virtually every sector of the Chinese economy through administrative regulation and/or state ownership; and actions of the Chinese central and local government authorities continue to have a substantial effect on economic conditions in China. In addition, previously the Chinese government has from time to time taken actions that influence the prices at which certain goods may be sold, encourage companies to invest or concentrate in particular industries, induce mergers between companies in certain industries and induce private companies to publicly offer their securities to increase or continue the rate of economic growth, control the rate of inflation or otherwise regulate economic expansion.

This may increase the Fund’s volatility and cause the performance of a relatively smaller number of issuers to have a greater impact on the Fund’s performance.

Equity Market Risk. The equity securities held in the Fund’s portfolio may experience sudden, unpredictable drops in value or long periods of decline in value. This may occur because of factors that affect securities markets generally or factors affecting specific industries, sectors or companies in which the Fund invests. Common stocks are susceptible to general stock market fluctuations and to volatile increases and decreases in value as market confidence in and perceptions of their issuers change. The Fund’s NAV and market price may fluctuate significantly in response to these and other factors. As a result, an investor could lose money over short or long periods of time.

ETF Risks. The Fund is an ETF and, as a result of an ETF’s structure, is exposed to the following risks:

◦Authorized Participants (“APs”), Market Makers, and Liquidity Providers Concentration Risk. The Fund has a limited number of financial institutions that may act as APs. In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, shares of the Fund may trade at a material discount to NAV and possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions.

◦Costs of Buying or Selling Shares of the Fund. Due to the costs of buying or selling shares of the Fund, including brokerage commissions imposed by brokers and bid/ask spreads, frequent trading of shares of the Fund may significantly reduce investment results and an investment in shares of the Fund may not be advisable for investors who anticipate regularly making small investments.

◦Shares of the Fund May Trade at Prices Other Than NAV. As with all ETFs, shares of the Fund may be bought and sold in the secondary market at market prices. The price of shares of the Fund, like the price of all traded securities, will be subject to factors such as supply and demand, as well as the current value of the Fund’s portfolio holdings. Although it is expected that the market price of the shares of the Fund will approximate the Fund’s NAV, there may be times when the market price of the shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount). This risk is heightened in times of market volatility, periods of steep market declines, and periods when there is limited trading activity for shares in the secondary market, in which case such premiums or discounts may be significant. Shares of the Fund will be bought and sold in the secondary market at market prices.

◦Trading. Although shares of the Fund are listed for trading on a national securities exchange, such as the Nasdaq Stock Market LLC (the “Exchange”), and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that shares of the Fund will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of shares of the Fund may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than shares of the Fund, and this could lead to differences between the market price of the shares of the Fund and the underlying value of those shares.

Sector Risk. To the extent the Fund invests more heavily in particular sectors of the economy, its performance will be especially sensitive to developments that significantly affect those sectors.

◦Health Care Sector Risk. Companies in the health care sector are subject to extensive government regulation and their profitability can be significantly affected by restrictions on government reimbursement for medical expenses, rising costs of medical products and services, pricing pressure (including price discounting), limited product lines and an increased emphasis on the delivery of healthcare through outpatient services.

◦Information Technology Sector Risk.The Fund may invest in companies in the information technology sector, and therefore the performance of the Fund could be negatively impacted by events affecting this sector. Market or economic factors impacting information technology companies and companies that rely heavily on technological advances could have a significant effect on the value of the Fund’s investments. The value of stocks of information technology companies and companies that rely heavily on technology is particularly vulnerable to rapid changes in technology product cycles, rapid product obsolescence, government regulation and competition, both domestically and internationally, including competition from foreign competitors with lower production costs. Stocks of information technology companies and companies that rely heavily on technology, especially those of smaller, less-seasoned companies, tend to be more volatile than the overall market. Information technology companies are heavily dependent on patent and intellectual property rights, the loss or impairment of which may adversely affect profitability.

This risk is heightened in times of market volatility, periods of steep market declines, and periods when there is limited trading activity for shares in the secondary market, in which case such premiums or discounts may be significant. Shares of the Fund will be bought and sold in the secondary market at market prices.

Trading. Although shares of the Fund are listed for trading on a national securities exchange, such as the Nasdaq Stock Market LLC (the “Exchange”), and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that shares of the Fund will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of shares of the Fund may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than shares of the Fund, and this could lead to differences between the market price of the shares of the Fund and the underlying value of those shares.

As a result, the Fund’s performance may be adversely affected if securities of large-capitalization companies underperform securities of smaller-capitalization companies or the market as a whole. The securities of large-capitalization companies may be relatively mature compared to smaller companies and therefore subject to slower growth during times of economic expansion.

Tracking Risk. The Fund’s return may not track the return of the Index for a number of reasons. For example, the Fund incurs a number of operating expenses not applicable to the Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund’s securities holdings to reflect changes in the composition of the Index. In addition, when the Fund uses a representative sampling approach, the Fund may not be as well correlated with the return of the Index as when the Fund purchases all of the securities in the Index in the proportions in which they are represented in the Index. To the extent the Fund calculates its NAV based on fair value prices and the value of the Index is based on securities’ closing prices on local foreign markets (i.e., the value of the Index is not based on fair value prices), the Fund’s ability to track the Index may be adversely affected.

Foreign Securities Risk. Investments in non-U.S. securities involve certain risks that may not be present with investments in U.S. securities. For example, investments in non-U.S. securities may be subject to risk of loss due to foreign currency fluctuations or to political or economic instability. Investments in non-U.S. securities also may be subject to withholding or other taxes and may be subject to additional trading, settlement, custodial, and operational risks. These and other factors can make investments in the Fund more volatile and potentially less liquid than other types of investments. Foreign securities held by the Fund may trade on markets that are closed when U.S. markets are open, which may lead to a difference in the value of the Fund and the underlying foreign securities.

Equity Market Risk. The equity securities held in the Fund’s portfolio may experience sudden, unpredictable drops in value or long periods of decline in value.

Common stocks are susceptible to general stock market fluctuations and to volatile increases and decreases in value as market confidence in and perceptions of their issuers change.

ETF Risks. The Fund is an ETF and, as a result of an ETF’s structure, is exposed to the following risks:

◦Authorized Participants (“APs”), Market Makers, and Liquidity Providers Concentration Risk. The Fund has a limited number of financial institutions that may act as APs. In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, shares of the Fund may trade at a material discount to NAV and possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform

these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions.

◦Costs of Buying or Selling Shares of the Fund. Due to the costs of buying or selling shares of the Fund, including brokerage commissions imposed by brokers and bid/ask spreads, frequent trading of shares of the Fund may significantly reduce investment results and an investment in shares of the Fund may not be advisable for investors who anticipate regularly making small investments.

◦Shares of the Fund May Trade at Prices Other Than NAV. As with all ETFs, shares of the Fund may be bought and sold in the secondary market at market prices. The price of shares of the Fund, like the price of all traded securities, will be subject to factors such as supply and demand, as well as the current value of the Fund’s portfolio holdings. Although it is expected that the market price of the shares of the Fund will approximate the Fund’s NAV, there may be times when the market price of the shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount).

European Investments Risk. The Fund is more exposed to the economic and political risks of Europe and of the European countries in which it invests than funds whose investments are more geographically diversified. Adverse economic and political events in Europe may cause the Fund’s investments to decline in value. The economies and markets of European countries are often closely connected and interdependent, and events in one country in Europe can have an adverse impact on other European countries. The Fund makes investments in securities of issuers that are domiciled in, or have significant operations in, member countries of the European Union (the “EU”) that are subject to economic and monetary controls that can adversely affect the Fund’s investments. The European financial markets have experienced volatility and adverse trends in recent years and these events have adversely affected the exchange rate of the euro and may continue to significantly affect other European countries. Decreasing imports or exports, changes in governmental or EU regulations on trade, changes in the exchange rate of the euro, the default or threat of default by an EU member country on its sovereign debt, and/or an economic recession in an EU member country may have a significant adverse effect on the economies of EU member countries and their trading partners, including some or all of the European countries in which the Fund invests.The risks of investing in the United Kingdom (UK) have been heightened as a result of Brexit, the formal steps taken by the United Kingdom to exit the EU, which has resulted in increased volatility and triggered political, economic, and legal uncertainty. Although the UK has formally left the EU, uncertainty remains as to the long-term consequences of Brexit and issuers in the UK may experience lower growth as a result.

Although the Fund intends to invest in a variety of securities and instruments, the Fund is considered to be non-diversified, which means that it may invest more of its assets in the securities of a single issuer or a smaller number of issuers than if it were a diversified fund. As a result, the Fund may be more exposed to the risks associated with and developments affecting an individual issuer or a smaller number of issuers than a fund that invests more widely. This may increase the Fund’s volatility and cause the performance of a relatively smaller number of issuers to have a greater impact on the Fund’s performance.

Equity Market Risk. The equity securities held in the Fund’s portfolio may experience sudden, unpredictable drops in value or long periods of decline in value. This may occur because of factors that affect securities markets generally or factors affecting specific industries, sectors or companies in which the Fund invests. Common stocks are susceptible to general stock market fluctuations and to volatile increases and decreases in value as market confidence in and perceptions of their issuers change. The Fund’s NAV and market price may fluctuate significantly in response to these and other factors. As a result, an investor could lose money over short or long periods of time.

ETF Risks. The Fund is an ETF and, as a result of an ETF’s structure, is exposed to the following risks:

◦Authorized Participants (“APs”), Market Makers, and Liquidity Providers Concentration Risk. The Fund has a limited number of financial institutions that may act as APs. In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, shares of the Fund may trade at a material discount to NAV and possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions.

◦Costs of Buying or Selling Shares of the Fund. Due to the costs of buying or selling shares of the Fund, including brokerage commissions imposed by brokers and bid/ask spreads, frequent trading of shares of the Fund may significantly reduce investment results and an investment in shares of the Fund may not be advisable for investors who anticipate regularly making small investments.

◦Shares of the Fund May Trade at Prices Other Than NAV. As with all ETFs, shares of the Fund may be bought and sold in the secondary market at market prices. The price of shares of the Fund, like the price of all traded securities, will be subject to factors such as supply and demand, as well as the current value of the Fund’s portfolio holdings. Although it is expected that the market price of the shares of the Fund will approximate the Fund’s NAV, there may be times when the market price of the shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount). This risk is heightened in times of market volatility, periods of steep market declines, and periods when there is limited trading activity for shares in the secondary market, in which case such premiums or discounts may be significant. Shares of the Fund will be bought and sold in the secondary market at market prices.

◦Trading. Although shares of the Fund are listed for trading on a national securities exchange, such as NYSE Arca, Inc. (the “Exchange”), and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that shares of the Fund will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of shares of the Fund may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than shares of the Fund, and this could lead to differences between the market price of the shares of the Fund and the underlying value of those shares.

Additionally, the Fund’s return may not track the return of the Index if the Fund is not able to replicate the holdings of the Index due to the diversification requirements described above under “Tax Risk,” which apply to the Fund but not the Index.

Concentration in Real Estate Risk. The Index, and consequently the Fund, is expected to concentrate its investments (i.e., hold more than 25% of its total assets) in real estate companies. As a result, the value of the Fund’s shares may rise and fall more than the value of shares of a fund that invests in securities of companies in a broader range of industries. In addition, at times, the real estate industry may be out of favor and underperform other industries or groups of industries.

International Operations Risk. Investments in companies with significant business operations outside of the United States may involve certain risks that may not be present with investments in U.S. companies. For example, international operations may be subject to risk of loss due to foreign currency fluctuations; changes in foreign political and economic environments, regionally, nationally, and locally; challenges of complying with a wide variety of foreign laws, including corporate governance, operations, taxes, and litigation; differing lending practices; differences in cultures; changes in applicable laws and regulations in the United States that affect international operations; changes in applicable laws and regulations in foreign jurisdictions; difficulties in managing international operations; and obstacles to the repatriation of earnings and cash. These and other factors can make an investment in the Fund more volatile than other types of investments.

Pacer Hotel & Lodging Real Estate ETF | Real Estate Companies Risk Member

Prospectus [Line Items]

Risk [Text Block]

Real Estate Companies Risk. The Fund invests in real estate companies, including REITs and real estate holdings companies, which will expose investors to the risks of owning real estate directly, as well as to the risks that relate specifically to the way in which such companies are organized and operated. Real estate is highly sensitive to general and local economic conditions and developments. The U.S. real estate market may, in the future, experience and has, in the past, experienced a decline in value, with certain regions experiencing significant losses in property values. Many real estate companies, including REITs, utilize leverage (and some may be highly leveraged), which increases investment risk and the risk normally associated with debt financing, and could potentially increase the Fund’s volatility and losses. Exposure to such real estate may adversely affect Fund performance.

In addition to the foregoing risks common to most real estate companies, companies in certain real estate sectors may have additional unique risks.

◦Risks of Investing in the Hotel & Lodging Real Estate Sector. Companies in the Hotel & Lodging Real Estate sector may be affected by unique supply and demand factors that do not apply to other real estate sectors. Weak economic conditions in some parts of the world, changes in oil prices and currency values, political instability in some areas, and the uncertainty over how long any of these conditions will continue, could continue to have a negative impact on the lodging industry. As a result of such current economic conditions and uncertainty, the lodging industry may continue to experience weakened demand for occupancy in some markets.

▪REIT Investment Risk. Investments in REITs involve unique risks. REITs may have limited financial resources, may trade less frequently and in limited volume, and may be more volatile than other securities. In addition, to the extent the Fund holds interests in REITs, it is expected that investors in the Fund will bear two layers of asset-based management fees and expenses (directly at the Fund level and indirectly at the REIT level). The risks of investing in REITs include certain risks associated with the direct ownership of real estate and the real estate industry in general. These include risks related to general, regional and local economic conditions; fluctuations in interest rates and property tax rates; shifts in zoning laws, environmental regulations and other governmental action such as the exercise of eminent domain; cash flow dependency; increased operating expenses; lack of availability of mortgage funds; losses due to natural disasters; overbuilding; losses due to casualty or condemnation; changes in property values and rental rates; and other factors.

In addition to these risks, REITs are dependent upon management skills and generally may not be diversified. REITs are also subject to heavy cash flow dependency, defaults by borrowers and self-liquidation. In addition, REITs could possibly fail to qualify for the beneficial tax treatment available to REITs under the Internal Revenue Code of 1986, or to maintain their exemptions from registration under the Investment Company Act of 1940, as amended (the “1940 Act”). The Fund expects that dividends received from a REIT and distributed to Fund shareholders generally will be taxable to the shareholder as ordinary income, but may be taxable as return of capital. In the event of a default by a borrower or lessee, the REIT may experience delays in enforcing its rights as a mortgagee or lessor and may incur substantial costs associated with protecting investments.

Pacer Hotel & Lodging Real Estate ETF | Tax Risk Member

Prospectus [Line Items]

Risk [Text Block]

Tax Risk. To qualify for the favorable tax treatment generally available to regulated investment companies, the Fund must satisfy certain diversification requirements. In particular, the Fund generally may not acquire a security if, as a result of the acquisition, more than 50% of the value of the Fund’s assets would be invested in (a) issuers in which the

Fund has, in each case, invested more than 5% of the Fund’s assets or (b) issuers more than 10% of whose outstanding voting securities are owned by the Fund. While the weighting of the Index is not inconsistent with these rules, given the concentration of the Index in a relatively small number of securities, it may not always be possible for the Fund to fully implement a replication strategy or a representative sampling strategy while satisfying these diversification requirements. The Fund’s efforts to satisfy the diversification requirements may affect the Fund’s execution of its investment strategy and may cause the Fund’s return to deviate from that of the Index, and the Fund’s efforts to replicate or represent the Index may cause it inadvertently to fail to satisfy the diversification requirements. If the Fund were to fail to satisfy the diversification requirements, it could incur penalty taxes and be forced to dispose of certain assets, or it could fail to qualify as a regulated investment company. If the Fund were to fail to qualify as a regulated investment company, it would be taxed in the same manner as an ordinary corporation, and distributions to its shareholders would not be deductible by the Fund in computing its taxable income.

Tax Risk. To qualify for the favorable tax treatment generally available to regulated investment companies, the Fund must satisfy certain diversification requirements. In particular, the Fund generally may not acquire a security if, as a result of the acquisition, more than 50% of the value of the Fund’s assets would be invested in (a) issuers in which the

Fund has, in each case, invested more than 5% of the Fund’s assets or (b) issuers more than 10% of whose outstanding voting securities are owned by the Fund. While the weighting of the Index is not inconsistent with these rules, given the concentration of the Index in a relatively small number of securities, it may not always be possible for the Fund to fully implement a replication strategy or a representative sampling strategy while satisfying these diversification requirements. The Fund’s efforts to satisfy the diversification requirements may affect the Fund’s execution of its investment strategy and may cause the Fund’s return to deviate from that of the Index, and the Fund’s efforts to replicate or represent the Index may cause it inadvertently to fail to satisfy the diversification requirements. If the Fund were to fail to satisfy the diversification requirements, it could incur penalty taxes and be forced to dispose of certain assets, or it could fail to qualify as a regulated investment company. If the Fund were to fail to qualify as a regulated investment company, it would be taxed in the same manner as an ordinary corporation, and distributions to its shareholders would not be deductible by the Fund in computing its taxable income.

Risks of Investing in the Apartments & Residential Real Estate Sector. Companies in the Apartments & Residential Real Estate sector may be affected by unique supply and demand factors that do not apply to other real estate sectors. Residential real estate development is particularly subject to changes in financing costs, occupancy rates, the ability to obtain zoning or other permits or government approvals, labor costs, and scheduling delays. Additionally, such companies may face significant costs associated with compliance (or failure to comply with) the accessibility provisions of federal, state or local requirements.

Non-Diversification Risk. Although the Fund intends to invest in a variety of securities and instruments, the Fund is considered to be non-diversified, which means that it may invest more of its assets in the securities of a single issuer or a smaller number of issuers than if it were a diversified fund. As a result, the Fund may be more exposed to the risks associated with and developments affecting an individual issuer or a smaller number of issuers than a fund that invests more widely. This may increase the Fund’s volatility and cause the performance of a relatively smaller number of issuers to have a greater impact on the Fund’s performance.

Equity Market Risk. The equity securities held in the Fund’s portfolio may experience sudden, unpredictable drops in value or long periods of decline in value. This may occur because of factors that affect securities markets generally or factors affecting specific industries, sectors or companies in which the Fund invests. Common stocks are susceptible to general stock market fluctuations and to volatile increases and decreases in value as market confidence in and perceptions of their issuers change. The Fund’s NAV and market price may fluctuate significantly in response to these and other factors. As a result, an investor could lose money over short or long periods of time.

ETF Risks. The Fund is an ETF and, as a result of an ETF’s structure, is exposed to the following risks:

◦Authorized Participants (“APs”), Market Makers, and Liquidity Providers Concentration Risk. The Fund has a limited number of financial institutions that may act as APs. In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, shares of the Fund may trade at a material discount to NAV and possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions.

◦Costs of Buying or Selling Shares of the Fund. Due to the costs of buying or selling shares of the Fund, including brokerage commissions imposed by brokers and bid/ask spreads, frequent trading of shares of the Fund may significantly reduce investment results and an investment in shares of the Fund may not be advisable for investors who anticipate regularly making small investments.

◦Shares of the Fund May Trade at Prices Other Than NAV. As with all ETFs, shares of the Fund may be bought and sold in the secondary market at market prices. The price of shares of the Fund, like the price of all traded securities, will be subject to factors such as supply and demand, as well as the current value of the Fund’s portfolio holdings. Although it is expected that the market price of the shares of the Fund will approximate the Fund’s NAV, there may be times when the market price of the shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount). This risk is heightened in times of market volatility, periods of steep market declines, and periods when there is limited trading activity for shares in the secondary market, in which case such premiums or discounts may be significant. Shares of the Fund will be bought and sold in the secondary market at market prices.

◦Trading. Although shares of the Fund are listed for trading on a national securities exchange, such as NYSE Arca, Inc. (the “Exchange”), and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that shares of the Fund will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of shares of the Fund may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than shares of the Fund, and this could lead to differences between the market price of the shares of the Fund and the underlying value of those shares.

These factors may negatively affect the Fund’s performance.

As a result, the value of the Fund’s shares may rise and fall more than the value of shares of a fund that invests in securities of companies in a broader range of industries. In addition, at times, the real estate industry may be out of favor and underperform other industries or groups of industries.

International Operations Risk. Investments in companies with significant business operations outside of the United States may involve certain risks that may not be present with investments in U.S. companies. For example, international operations may be subject to risk of loss due to foreign currency fluctuations; changes in foreign political and economic environments, regionally, nationally, and locally; challenges of complying with a wide variety of foreign laws, including corporate governance, operations, taxes, and litigation; differing lending practices; differences in cultures; changes in applicable laws and regulations in the United States that affect international operations; changes in applicable laws and regulations in foreign jurisdictions; difficulties in managing international operations; and obstacles to the repatriation of earnings and cash. These and other factors can make an investment in the Fund more volatile than other types of investments.

Pacer Healthcare Real Estate ETF | Real Estate Companies Risk Member

▪Real Estate Companies Risk. The Fund invests in real estate companies, including REITs and real estate holdings companies, which will expose investors to the risks of owning real estate directly, as well as to the risks that relate specifically to the way in which such companies are organized and operated. Real estate is highly sensitive to general and local economic conditions and developments. The U.S. real estate market may, in the future, experience and has, in the past, experienced a decline in value, with certain regions experiencing significant losses in property values. Many real estate companies, including REITs, utilize leverage (and some may be highly leveraged), which increases investment risk and the risk normally associated with debt financing, and could potentially increase the Fund’s volatility and losses. Exposure to such real estate may adversely affect Fund performance.

In addition to the foregoing risks common to most real estate companies, companies in certain real estate sectors may have additional unique risks.

◦Risks of Investing in the Healthcare Real Estate Sector. Companies in the Healthcare Real Estate sector may be affected by unique supply and demand factors that do not apply to other real estate sectors. Such companies may be subject to risks related to severe cold and flu seasons, epidemics, or any other widespread illnesses that could affect the occupancy of healthcare properties, including seniors housing. Additionally, healthcare companies may be significantly dependent on one or a small number of long-term management agreements for seniors housing communities, which may subject such companies to the risks affecting such management companies.

Pacer Healthcare Real Estate ETF | REIT Investment Risk Member

Prospectus [Line Items]

Risk [Text Block]

REIT Investment Risk. Investments in REITs involve unique risks. REITs may have limited financial resources, may trade less frequently and in limited volume, and may be more volatile than other securities. In addition, to the extent the Fund holds interests in REITs, it is expected that investors in the Fund will bear two layers of asset-based management fees and expenses (directly at the Fund level and indirectly at the REIT level). The risks of investing in REITs include certain risks associated with the direct ownership of real estate and the real estate industry in general. These include risks related to general, regional and local economic conditions; fluctuations in interest rates and property tax rates; shifts in zoning laws, environmental regulations and other governmental action such as the exercise of eminent domain; cash flow dependency; increased operating expenses; lack of availability of mortgage funds; losses due to natural disasters; overbuilding; losses due to casualty or condemnation; changes in property values and rental rates; and other factors.

In addition to these risks, REITs are dependent upon management skills and generally may not be diversified. REITs are also subject to heavy cash flow dependency, defaults by borrowers and self-liquidation. In addition, REITs could possibly fail to qualify for the beneficial tax treatment available to REITs under the Internal Revenue Code of 1986, or to maintain their exemptions from registration under the Investment Company Act of 1940, as amended (the “1940 Act”). The Fund expects that dividends received from a REIT and distributed to Fund shareholders generally will be taxable to the shareholder as ordinary income, but may be taxable as return of capital. In the event of a default by a borrower or lessee, the REIT may experience delays in enforcing its rights as a mortgagee or lessor and may incur substantial costs associated with protecting investments.

In particular, the Fund generally may not acquire a security if, as a result of the acquisition, more than 50% of the value of the Fund’s assets would be invested in (a) issuers in which the

While the weighting of the Index is not inconsistent with these rules, given the concentration of the Index in a relatively small number of securities, it may not always be possible for the Fund to fully implement a replication strategy or a representative sampling strategy while satisfying these diversification requirements. The Fund’s efforts to satisfy the diversification requirements may affect the Fund’s execution of its investment strategy and may cause the Fund’s return to deviate from that of the Index, and the Fund’s efforts to replicate or represent the Index may cause it inadvertently to fail to satisfy the diversification requirements. If the Fund were to fail to satisfy the diversification requirements, it could incur penalty taxes and be forced to dispose of certain assets, or it could fail to qualify as a regulated investment company. If the Fund were to fail to qualify as a regulated investment company, it would be taxed in the same manner as an ordinary corporation, and distributions to its shareholders would not be deductible by the Fund in computing its taxable income.

Real estate is highly sensitive to general and local economic conditions and developments. The U.S. real estate market may, in the future, experience and has, in the past, experienced a decline in value, with certain regions experiencing significant losses in property values. Many real estate companies, including REITs, utilize leverage (and some may be highly leveraged), which increases investment risk and the risk normally associated with debt financing, and could potentially increase the Fund’s volatility and losses. Exposure to such real estate may adversely affect Fund performance.

In addition to the foregoing risks common to most real estate companies, companies in certain real estate sectors may have additional unique risks.

◦Risks of Investing in the Industrial Real Estate Sector. Companies in the Industrial Real Estate sector may be affected by unique supply and demand factors that do not apply to other real estate sectors. For example, industrial real estate may be more susceptible to changes in interest rates, macroeconomic trends, government regulation, and tax regulation than other real estate sectors. Industrial real estate may also be concentrated in logistics-related industries, which could expose industrial real estate companies to the risks of a downturn affecting logistics companies.

▪REIT Investment Risk. Investments in REITs involve unique risks. REITs may have limited financial resources, may trade less frequently and in limited volume, and may be more volatile than other securities. In addition, to the extent the Fund holds interests in REITs, it is expected that investors in the Fund will bear two layers of asset-based management fees and expenses (directly at the Fund level and indirectly at the REIT level). The risks of investing in REITs include certain risks associated with the direct ownership of real estate and the real estate industry in general. These include risks related to general, regional and local economic conditions; fluctuations in interest rates and property tax rates; shifts in zoning laws, environmental regulations and other governmental action such as the exercise of eminent domain; cash flow dependency; increased operating expenses; lack of availability of mortgage funds; losses due to natural disasters; overbuilding; losses due to casualty or condemnation; changes in property values and rental rates; and other factors.

In addition to these risks, REITs are dependent upon management skills and generally may not be diversified. REITs are also subject to heavy cash flow dependency, defaults by borrowers and self-liquidation. In addition, REITs could possibly fail to qualify for the beneficial tax treatment available to REITs under the Internal Revenue Code of 1986, or to maintain their exemptions from registration under the Investment Company Act of 1940, as amended (the “1940

Act”). The Fund expects that dividends received from a REIT and distributed to Fund shareholders generally will be taxable to the shareholder as ordinary income, but may be taxable as return of capital. In the event of a default by a borrower or lessee, the REIT may experience delays in enforcing its rights as a mortgagee or lessor and may incur substantial costs associated with protecting investments.

Tax Risk. To qualify for the favorable tax treatment generally available to regulated investment companies, the Fund must satisfy certain diversification requirements. In particular, the Fund generally may not acquire a security if, as a result of the acquisition, more than 50% of the value of the Fund’s assets would be invested in (a) issuers in which the Fund has, in each case, invested more than 5% of the Fund’s assets or (b) issuers more than 10% of whose outstanding voting securities are owned by the Fund. While the weighting of the Index is not inconsistent with these rules, given the concentration of the Index in a relatively small number of securities, it may not always be possible for the Fund to fully implement a replication strategy or a representative sampling strategy while satisfying these diversification requirements. The Fund’s efforts to satisfy the diversification requirements may affect the Fund’s execution of its investment strategy and may cause the Fund’s return to deviate from that of the Index, and the Fund’s efforts to replicate or represent the Index may cause it inadvertently to fail to satisfy the diversification requirements. If the Fund were to fail to satisfy the diversification requirements, it could incur penalty taxes and be forced to dispose of certain assets, or it could fail to qualify as a regulated investment company. If the Fund were to fail to qualify as a regulated investment company, it would be taxed in the same manner as an ordinary corporation, and distributions to its shareholders would not be deductible by the Fund in computing its taxable income.

Risk [Text Block]

Non-Diversification Risk. Although the Fund intends to invest in a variety of securities and instruments, the Fund is considered to be non-diversified, which means that it may invest more of its assets in the securities of a single issuer or a smaller number of issuers than if it were a diversified fund. As a result, the Fund may be more exposed to the risks associated with and developments affecting an individual issuer or a smaller number of issuers than a fund that invests more widely. This may increase the Fund’s volatility and cause the performance of a relatively smaller number of issuers to have a greater impact on the Fund’s performance.

Calculation Methodology Risk. The Index relies directly or indirectly 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, the Index Provider, or the Adviser can offer assurances that the Index’s calculation methodology or sources of information will provide an accurate assessment of included components or a correct valuation of securities, nor can they guarantee the availability or timeliness of the production of the Index.

Equity Market Risk. The equity securities held in the Fund’s portfolio may experience sudden, unpredictable drops in value or long periods of decline in value. This may occur because of factors that affect securities markets generally or factors affecting specific industries, sectors or companies in which the Fund invests. Common stocks are susceptible to general stock market fluctuations and to volatile increases and decreases in value as market confidence in and perceptions of their issuers change. The Fund’s NAV and market price may fluctuate significantly in response to these and other factors. As a result, an investor could lose money over short or long periods of time.

▪ETF Risks. The Fund is an ETF and, as a result of an ETF’s structure, is exposed to the following risks:

◦Authorized Participants (“APs”), Market Makers, and Liquidity Providers Concentration Risk. The Fund has a limited number of financial institutions that may act as APs. In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, shares of the Fund may trade at a material discount to NAV and possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions.

◦Costs of Buying or Selling Shares of the Fund. Due to the costs of buying or selling shares of the Fund, including brokerage commissions imposed by brokers and bid/ask spreads, frequent trading of shares of the Fund may significantly reduce investment results and an investment in shares of the Fund may not be advisable for investors who anticipate regularly making small investments.

◦Shares of the Fund May Trade at Prices Other Than NAV. As with all ETFs, shares of the Fund may be bought and sold in the secondary market at market prices. The price of shares of the Fund, like the price of all traded securities, will be subject to factors such as supply and demand, as well as the current value of the Fund’s portfolio holdings. Although it is expected that the market price of the shares of the Fund will approximate the Fund’s NAV, there may be times when the market price of the shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount). This risk is heightened in times of market volatility, periods of steep market declines, and periods when there is limited trading activity for shares in the secondary market, in which case such premiums or discounts may be significant. Because securities held by the Fund trade on foreign exchanges that are closed when the Fund’s primary listing exchange is open, the Fund is likely to experience premiums and discounts greater than those of domestic ETFs.

◦Trading. Although shares of the Fund are listed for trading on a national securities exchange, such as NYSE Arca, Inc. (the “Exchange”), and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that shares of the Fund will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of shares of the Fund may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than shares of the Fund, and this could lead to differences between the market price of the shares of the Fund and the underlying value of those shares.

The Fund invests in securities included in the Index, regardless of their investment merits. The Fund does not take defensive positions under any market conditions, including conditions that are adverse to the performance of the Fund.

Tracking Risk. The Fund’s return may not track the return of the Index for a number of reasons. For example, the Fund incurs a number of operating expenses not applicable to the Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund’s securities holdings to reflect changes in the composition of the Index. Additionally, the Fund’s return may not track the return of the Index if the Fund is not able to replicate the holdings of the Index due to the diversification requirements described above under “Tax Risk,” which apply to the Fund but not the Index.

▪Sector Risk. To the extent the Fund invests more heavily in particular sectors of the economy, its performance will be especially sensitive to developments that significantly affect those sectors.

•Communication Services Sector Risk. The Fund is generally expected to invest significantly in companies in the communications services sector, and therefore the performance of the Fund could be negatively impacted by events affecting this sector. Communications services companies are subject to extensive government regulation. The costs of complying with governmental regulations, delays or failure to receive required regulatory approvals, or the enactment of new adverse regulatory requirements may adversely affect the business of the such companies. Companies in the communications services sector can also be significantly affected by intense competition, including competition with alternative technologies such as wireless communications (including with 5G and other technologies), product compatibility, consumer preferences, rapid product obsolescence, and research and development of new products. Technological innovations may make the products and services of such companies obsolete.

Currency Exchange Rate Risk. The Fund’s assets may include investments denominated in non-U.S. currencies, such as the euro, or in securities or other assets that provide exposure to such currencies. Changes in currency exchange rates and the relative value of non-U.S. currencies will affect the value of the Fund’s investment and the value of your Fund shares. Currency exchange rates can be very volatile and can change quickly and unpredictably. As a result, the value of an investment in the Fund may change quickly and without warning and you may lose money.

Foreign Securities Risk. Investments in non-U.S. securities involve certain risks that may not be present with investments in U.S. securities. For example, investments in non-U.S. securities may be subject to risk of loss due to foreign currency fluctuations or to political or economic instability. Investments in non-U.S. securities also may be subject to withholding or other taxes and may be subject to additional trading, settlement, custodial, and operational risks. These and other factors can make investments in the Fund more volatile and potentially less liquid than other types of investments. Foreign securities held by the Fund may trade on markets that are closed when U.S. markets are open, which may lead to a difference in the value of the Fund and the underlying foreign securities.

Concentration in Real Estate Risk. The Index, and consequently the Fund, is expected to concentrate its investments (i.e., hold more than 25% of its total assets) in real estate companies. As a result, the value of the Fund’s shares may rise and fall more than the value of shares of a fund that invests in securities of companies in a broader range of industries. In addition, at times, the real estate industry may be out of favor and underperform other industries or groups of industries.

International Operations Risk. Investments in companies with significant business operations outside of the United States may involve certain risks that may not be present with investments in U.S. companies. For example, international operations may be subject to risk of loss due to foreign currency fluctuations; changes in foreign political and economic environments, regionally, nationally, and locally; challenges of complying with a wide variety of foreign laws, including corporate governance, operations, taxes, and litigation; differing lending practices; differences in cultures; changes in applicable laws and regulations in the United States that affect international operations; changes in applicable laws and regulations in foreign jurisdictions; difficulties in managing international operations; and obstacles to the repatriation of earnings and cash. These and other factors can make an investment in the Fund more volatile than other types of investments.

▪ETF Risks. The Fund is an ETF and, as a result of an ETF’s structure, is exposed to the following risks:

◦Authorized Participants (“APs”), Market Makers, and Liquidity Providers Concentration Risk. The Fund has a limited number of financial institutions that may act as APs. In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, shares of the Fund may trade at a material discount to NAV and possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions.

◦Costs of Buying or Selling Shares of the Fund. Due to the costs of buying or selling shares of the Fund, including brokerage commissions imposed by brokers and bid/ask spreads, frequent trading of shares of the Fund may significantly reduce investment results and an investment in shares of the Fund may not be advisable for investors who anticipate regularly making small investments.

◦Shares of the Fund May Trade at Prices Other Than NAV. As with all ETFs, shares of the Fund may be bought and sold in the secondary market at market prices. The price of shares of the Fund, like the price of all traded securities, will be subject to factors such as supply and demand, as well as the current value of the Fund’s portfolio holdings. Although it is expected that the market price of the shares of the Fund will approximate the Fund’s NAV, there may be times when the market price of the shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount). This risk is heightened in times of market volatility, periods of steep market declines, and periods when there is limited trading activity for shares in the secondary market, in which case such premiums or discounts may be significant. Because securities held by the Fund trade on foreign exchanges that are closed when the Fund’s primary listing exchange is open, the Fund is likely to experience premiums and discounts greater than those of domestic ETFs.

◦Trading. Although shares of the Fund are listed for trading on a national securities exchange, such as Cboe BZX Exchange, Inc. (the “Exchange”), and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that shares of the Fund will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of shares of the Fund may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than shares of the Fund, and this could lead to differences between the market price of the shares of the Fund and the underlying value of those shares.

The securities of large-capitalization companies may be relatively mature compared to smaller companies and therefore subject to slower growth during times of economic expansion.

Passive Investment Risk. The Fund is not actively managed and the Adviser would not sell a security due to current or projected underperformance of a security, industry or sector, unless that security is removed from the Index or the selling of shares of that security is otherwise required upon a reconstitution of the Index in accordance with the Index methodology.

Tracking Risk. The Fund’s return may not track the return of the Index for a number of reasons. For example, the Fund incurs a number of operating expenses not applicable to the Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund’s securities holdings to reflect changes in the composition of the Index. In addition, when the Fund uses a representative sampling approach, the Fund may not be as well correlated with the return of the Index as when the Fund purchases all of the securities in the Index in the proportions in which they are represented in the Index. To the extent the Fund calculates its NAV based on fair value prices and the value of the Index is based on securities’ closing prices on local foreign markets (i.e., the value of the Index is not based on fair value prices), the Fund’s ability to track the Index may be adversely affected.

Mid-Capitalization Investing Risk. The Fund may invest in the securities of mid-capitalization companies. As a result, the Fund’s performance may be adversely affected if securities of mid-capitalization companies underperform securities of other capitalization ranges or the market as a whole. Securities of smaller companies trade in smaller volumes and are often more vulnerable to market volatility than securities of larger companies.

Risk [Text Block]

Currency Exchange Rate Risk. The Fund’s assets may include investments denominated in non-U.S. currencies, such as the euro, or in securities or other assets that provide exposure to such currencies. Changes in currency exchange rates and the relative value of non-U.S. currencies will affect the value of the Fund’s investment and the value of your Fund shares. Currency exchange rates can be very volatile and can change quickly and unpredictably. As a result, the value of an investment in the Fund may change quickly and without warning and you may lose money.

Pacer Autopilot Hedged European Index ETF | European Investment Risk Member

Risk [Text Block]

European Investments Risk. The Fund is more exposed to the economic and political risks of Europe and of the European countries in which it invests than funds whose investments are more geographically diversified. Adverse economic and political events in Europe may cause the Fund’s investments to decline in value. The economies and markets of European countries are often closely connected and interdependent, and events in one country in Europe can have an adverse impact on other European countries. The Fund makes investments in securities of issuers that are domiciled in, or have significant operations in, member countries of the European Union (the “EU”) that are subject to economic and monetary controls that can adversely affect the Fund’s investments. The European financial markets have experienced volatility and adverse trends in recent years and these events have adversely affected the exchange rate of the euro and may continue to significantly affect other European countries. Decreasing imports or exports, changes in governmental or EU regulations on trade, changes in the exchange rate of the euro, the default or threat of default by an EU member country on its sovereign debt, and/or an economic recession in an EU member country may have a significant adverse effect on the economies of EU member countries and their trading partners, including some or all of the European countries in which the Fund invests.The risks of investing in the United Kingdom (UK) have been heightened as a result of Brexit, the formal steps taken by the United Kingdom to exit the EU, which has resulted in increased volatility and triggered political, economic, and legal uncertainty. Although the UK has formally left the EU, uncertainty remains as to the long-term consequences of Brexit and issuers in the UK may experience lower growth as a result.

▪Foreign Securities Risk. Investments in non-U.S. securities involve certain risks that may not be present with investments in U.S. securities. For example, investments in non-U.S. securities may be subject to risk of loss due to foreign currency fluctuations or to political or economic instability. Investments in non-U.S. securities also may be subject to withholding or other taxes and may be subject to additional trading, settlement, custodial, and operational risks. These and other factors can make investments in the Fund more volatile and potentially less liquid than other

types of investments. Foreign securities held by the Fund may trade on markets that are closed when U.S. markets are open, which may lead to a difference in the value of the Fund and the underlying foreign securities.

Geographic Concentration Risk. To the extent the Fund invests a significant portion of its assets in the securities of companies of a single country or region, it is more likely to be impacted by events or conditions affecting that country or region. The Index’s, and therefore the Fund’s, heavy equity exposure to two countries (France and Germany) subjects the Fund to a higher degree of country risk than that of more geographically diversified international funds.

The Fund’s distributor does not maintain a secondary market in Fund shares.

Pacer Autopilot Hedged European Index ETF | Forward Currency Contracts Risk Member

Risk [Text Block]

Forward Currency Contracts Risk. Forward currency contracts and other currency management strategies may substantially change the Fund’s exposure to currency exchange rates and could result in losses to the Fund if currencies do not perform as expected or if the Fund is unable to quickly enter or exit such contracts. The use of forward currency contracts with third parties (i.e., “counterparties”) subjects the Fund to counterparty risk, including the risk that a counterparty to these contracts becomes bankrupt, defaults on its obligations, or otherwise fails to honor its obligations. If a counterparty defaults on its payment obligations, the Fund may lose money and the value of an investment in Fund shares may decrease. The use of forward currency contracts may create leverage (i.e., investment exposure greater than the dollar amount invested), thereby causing the Fund to be more volatile. Forward contracts require collateralization, and the commitment of a large portion of the Fund’s assets as collateral could impede portfolio management. Forward currency contracts are also subject to valuation risk, which is the risk that the contracts may be difficult to value and/or valued incorrectly.

Risk [Text Block]

Non-Diversification Risk. Although the Fund intends to invest in a variety of securities and instruments, the Fund is considered to be non-diversified, which means that it may invest more of its assets in the securities of a single issuer or a smaller number of issuers than if it were a diversified fund. As a result, the Fund may be more exposed to the risks associated with and developments affecting an individual issuer or a smaller number of issuers than a fund that invests more widely. This may increase the Fund’s volatility and cause the performance of a relatively smaller number of issuers to have a greater impact on the Fund’s performance.

Risk [Text Block]

Diversification Risk. The Fund is classified as “diversified” under the 1940 Act. However, the Fund may become “non‑diversified” solely as a result of a change in the relative market capitalization or index weighting of one or more constituents of the Index. Operating as “non-diversified” may make the Fund more susceptible to adverse developments affecting any single issuer held in its portfolio and may be more susceptible to greater losses because of these developments.

Equity Market Risk. The equity securities held in the Fund’s portfolio may experience sudden, unpredictable drops in value or long periods of decline in value. This may occur because of factors that affect securities markets generally or factors affecting specific industries, sectors or companies in which the Fund invests. Common stocks are susceptible to general stock market fluctuations and to volatile increases and decreases in value as market confidence in and perceptions of their issuers change. The Fund’s NAV and market price may fluctuate significantly in response to these and other factors. As a result, an investor could lose money over short or long periods of time.

Pacer WealthShield ETF | ETF Risks Member

Risk [Text Block]

ETF Risks. The Fund is an ETF and, as a result of an ETF’s structure, is exposed to the following risks:

◦Authorized Participants (“APs”), Market Makers, and Liquidity Providers Concentration Risk. The Fund has a limited number of financial institutions that may act as APs. In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, shares of the Fund may trade at a material discount to NAV and possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions.

◦Costs of Buying or Selling Shares of the Fund. Due to the costs of buying or selling shares of the Fund, including brokerage commissions imposed by brokers and bid/ask spreads, frequent trading of shares of the Fund may significantly reduce investment results and an investment in shares of the Fund may not be advisable for investors who anticipate regularly making small investments.

◦Shares of the Fund May Trade at Prices Other Than NAV. As with all ETFs, shares of the Fund may be bought and sold in the secondary market at market prices. The price of shares of the Fund, like the price of all traded securities, will be subject to factors such as supply and demand, as well as the current value of the Fund’s portfolio holdings. Although it is expected that the market price of the shares of the Fund will approximate the Fund’s NAV, there may be times when the market price of the shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount). This risk is heightened in times of market volatility, periods of steep market declines, and periods when there is limited trading activity for shares in the secondary market, in which case such premiums or discounts may be significant. Shares of the Fund will be bought and sold in the secondary market at market prices.

◦Trading. Although shares of the Fund are listed for trading on a national securities exchange, such as Cboe BZX Exchange, Inc. (the “Exchange”), and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that shares of the Fund will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of shares of the Fund may begin to mirror the liquidity of the Fund’s underlying portfolio

holdings, which can be significantly less liquid than shares of the Fund, and this could lead to differences between the market price of the shares of the Fund and the underlying value of those shares.

Risk [Text Block]

Fixed Income Risk. Generally, the value of fixed income securities will change inversely with changes in interest rates. As interest rates rise, the market value of fixed income securities tends to decrease. Conversely, as interest rates fall, the market value of fixed income securities tends to increase. This risk will be greater for long-term securities than for short-term securities. In recent periods, governmental financial regulators, including the U.S. Federal Reserve, have taken steps to increase interest rates. Changes in government intervention may have adverse effects on investments, volatility, and the liquidity of debt markets.

In addition, when the Fund uses a representative sampling approach, the Fund may not be as well correlated with the return of the Index as when the Fund purchases all of the securities in the Index in the proportions in which they are represented in the Index. To the extent the Fund calculates its NAV based on fair value prices and the value of the Index is based on securities’ closing prices on local foreign markets (i.e., the value of the Index is not based on fair value prices), the Fund’s ability to track the Index may be adversely affected.

To the extent the Fund uses a representative sampling approach, it will hold a smaller number of securities than are in the Index. As a result, an adverse development respecting an issuer of securities held by the Fund could result in a greater decline in the Fund’s net asset value than would be the case if the Fund held all of the securities in the Index. Conversely, a positive development relating to an issuer of securities in the Index that is not held by the Fund could cause the Fund to underperform the Index. To the extent the assets in the Fund are smaller, these risks may be greater.

Concentration Risk. If the Index concentrates in an industry or group of industries, the Fund’s investments may be concentrated accordingly. In such event, the value of the Fund’s shares may rise and fall more than the value of shares of a fund that invests in securities of companies in a broader range of industries. In addition, at times, an industry or group of industries in which the Fund is concentrated may be out of favor and underperform other industries or groups of industries.

Pacer WealthShield ETF | High Portfolio Turnover Risk Member

Risk [Text Block]

High Portfolio Turnover Risk. At times, the Fund may have a portfolio turnover rate substantially greater than 100%. A high portfolio turnover rate would result in correspondingly greater transaction expenses, including brokerage commissions, dealer mark ups and other transaction costs, on the sale of securities and on reinvestment in other securities and may result in reduced performance and the distribution to shareholders of additional capital gains for tax purposes. These factors may negatively affect the Fund’s performance.

Other Investment Companies Risk. The Fund will incur higher and duplicative expenses when it invests in other investment companies such as ETFs. There is also the risk that the Fund may suffer losses due to the investment practices of the underlying funds.

Investments in ETFs are also subject to the ETF Risks described above.

Pacer WealthShield ETF | REIT Investment Risk Member

Risk [Text Block]

REIT Investment Risk. Investments in REITs involve unique risks. REITs may have limited financial resources, may trade less frequently and in limited volume, and may be more volatile than other securities. In addition, to the extent the Fund holds interests in REITs, it is expected that investors in the Fund will bear two layers of asset-based management fees and expenses (directly at the Fund level and indirectly at the REIT level). The risks of investing in REITs include certain risks associated with the direct ownership of real estate and the real estate industry in general. These include risks related to general, regional and local economic conditions; fluctuations in interest rates and property tax rates; shifts in zoning laws, environmental regulations and other governmental action such as the exercise of eminent domain; cash flow dependency; increased operating expenses; lack of availability of mortgage funds; losses due to natural disasters; overbuilding; losses due to casualty or condemnation; changes in property values and rental rates; and other factors.In addition to these risks, REITs are dependent upon management skills and generally may not be diversified. REITs are also subject to heavy cash flow dependency, defaults by borrowers and self-liquidation. In addition, REITs could possibly fail to qualify for the beneficial tax treatment available to REITs under the Internal Revenue Code of 1986, or to maintain their exemptions from registration under the Investment Company Act of 1940, as amended (the “1940 Act”). The Fund expects that dividends received from a REIT and distributed to Fund shareholders generally will be taxable to the shareholder as ordinary income, but may be taxable as return of capital. In the event of a default by a borrower or lessee, the REIT may experience delays in enforcing its rights as a mortgagee or lessor and may incur substantial costs associated with protecting investments.

Monthly Exposure Risk. Because the Index will only change its exposure monthly, (i) the Index’s exposure may be affected by significant market movements at or near month end that are not predictive of the market’s performance for the subsequent month and (ii) changes to the Index’s exposure may lag a significant change in the market’s direction (up or down) by as long as a month if such changes first take effect at or near the beginning of a month. Such lags between market performance and changes to the Index’s exposure may result in significant underperformance relative to the broader equity or fixed income market.

High Portfolio Turnover Risk. At times, the Fund may have a portfolio turnover rate substantially greater than 100%. A high portfolio turnover rate would result in correspondingly greater transaction expenses, including brokerage commissions, dealer mark ups and other transaction costs, on the sale of securities and on reinvestment in other securities and may result in reduced performance and the distribution to shareholders of additional capital gains for tax purposes. These factors may negatively affect the Fund’s performance.

Other Investment Companies Risk. The Fund will incur higher and duplicative expenses when it invests in other investment companies such as ETFs. There is also the risk that the Fund may suffer losses due to the investment practices of the underlying funds. When the Fund invests in other investment companies, the Fund will be subject to substantially the same risks as those associated with the direct ownership of securities held by such investment companies. Investments in ETFs are also subject to the ETF Risks described above.

Risk [Text Block]

Non-Diversification Risk. Although the Fund intends to invest in a variety of securities and instruments, the Fund is considered to be non-diversified, which means that it may invest more of its assets in the securities of a single issuer or a smaller number of issuers than if it were a diversified fund. As a result, the Fund may be more exposed to the risks associated with and developments affecting an individual issuer or a smaller number of issuers than a fund that invests more widely. This may increase the Fund’s volatility and cause the performance of a relatively smaller number of issuers to have a greater impact on the Fund’s performance.

Diversification Risk. The Fund is classified as “diversified” under the 1940 Act. However, the Fund may become “non‑diversified” solely as a result of a change in the relative market capitalization or index weighting of one or more constituents of the Index. Operating as “non-diversified” may make the Fund more susceptible to adverse developments affecting any single issuer held in its portfolio and may be more susceptible to greater losses because of these developments.

Equity Market Risk. The equity securities held in the Fund’s portfolio may experience sudden, unpredictable drops in value or long periods of decline in value. This may occur because of factors that affect securities markets generally or factors affecting specific industries, sectors or companies in which the Fund invests. Common stocks are susceptible to general stock market fluctuations and to volatile increases and decreases in value as market confidence in and perceptions of their issuers change. The Fund’s NAV and market price may fluctuate significantly in response to these and other factors. As a result, an investor could lose money over short or long periods of time.

ETF Risks. The Fund is an ETF and, as a result of an ETF’s structure, is exposed to the following risks:

◦Authorized Participants (“APs”), Market Makers, and Liquidity Providers Concentration Risk. The Fund has a limited number of financial institutions that may act as APs. In addition, there may be a limited number of market

makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, shares of the Fund may trade at a material discount to NAV and possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions.

◦Costs of Buying or Selling Shares of the Fund. Due to the costs of buying or selling shares of the Fund, including brokerage commissions imposed by brokers and bid/ask spreads, frequent trading of shares of the Fund may significantly reduce investment results and an investment in shares of the Fund may not be advisable for investors who anticipate regularly making small investments.

◦Shares of the Fund May Trade at Prices Other Than NAV. As with all ETFs, shares of the Fund may be bought and sold in the secondary market at market prices. The price of shares of the Fund, like the price of all traded securities, will be subject to factors such as supply and demand, as well as the current value of the Fund’s portfolio holdings. Although it is expected that the market price of the shares of the Fund will approximate the Fund’s NAV, there may be times when the market price of the shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount). This risk is heightened in times of market volatility, periods of steep market declines, and periods when there is limited trading activity for shares in the secondary market, in which case such premiums or discounts may be significant. Shares of the Fund will be bought and sold in the secondary market at market prices.

◦Trading. Although shares of the Fund are listed for trading on a national securities exchange, such as NYSE Arca, Inc. (the “Exchange”), and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that shares of the Fund will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of shares of the Fund may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than shares of the Fund, and this could lead to differences between the market price of the shares of the Fund and the underlying value of those shares.

▪Alternator Strategy Risk. Because the Index will be comprised of only one Sub-Index each month, the Index may be comprised of low volatility securities during a period when such securities underperform high beta securities, or vice versa.

Volatile stocks may be subject to sharp swings in value, and may change unpredictably, affecting the value of such equity securities and, consequently, the value of Shares. High beta stocks are likely to underperform the broader market during periods of rapidly declining stock prices.

◦Low Volatility Risk. Low volatility investing entails investing in securities that are seen as having a lower risk profile than the overall markets. However, a portfolio comprised of low volatility stocks may not produce investment exposure that has lower variability to changes in such stocks’ price levels. Low volatility stocks are likely to underperform the broader market during periods of rapidly rising stock prices.

◦Momentum Investing Risk. Momentum investing is subject to the risk that the securities may be more volatile than the market as a whole, or that the returns on securities that previously have exhibited price momentum or proximity to price peaks are less than returns on other styles of investing. Momentum can turn quickly, and stocks

that previously have exhibited high momentum may not experience continued positive momentum. In addition, investor perceptions of the value of a company may turn quickly, and stocks that have recently set multiple price peaks may not continue to do so, may be considered overvalued, and may decline faster than other investments.

◦Quality Investing Risk. Securities that have previously been identified with quality characteristics may not continue to be quality companies, and the returns of such securities may be less than returns on other styles of investing. In addition, there may be periods when the quality style of investing is out of favor and therefore, the performance of the Fund may suffer.

◦Value Investing Risk. A “value” style of investing could produce poor results relative to other funds, even in a rising market, if the methodology used by the Index to determine a company’s “value” or prospects for exceeding earnings expectations or market conditions is wrong. In addition, “value stocks” can continue to be undervalued by the market for long periods of time.

Authorized Participants, Market Makers, and Liquidity Providers Concentration Risk. The Fund has a limited number of financial institutions that may act as Authorized Participants (“APs”). In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. APs are generally large institutional investors that have been authorized by the Fund’s distributor to purchase and redeem large blocks of Shares (known as “Creation Units”) pursuant to legal requirements by which the Fund may offer and redeem Shares. To the extent either of the following events occur, Shares of the Fund may trade at a material discount to NAV and possibly face delisting: (i) APs exit the business or otherwise become unable to process Creation Units and/or redemption orders and no other APs step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions.

Equity Market Risk. The equity securities held in the Fund’s portfolio may experience sudden, unpredictable drops in value or long periods of decline in value. This may occur because of factors that affect securities markets generally or factors affecting specific issuers, industries, or sectors in which the Fund invests. Common stocks are susceptible to general stock market fluctuations and to volatile increases and decreases in value as market confidence in and perceptions of their issuers change. The trading prices of equity securities and other instruments fluctuate in response to a variety of factors. The Fund’s NAV and market price may fluctuate significantly in response to these and other factors. As a result, an investor could lose money over short or long periods of time.

For example, the Fund incurs a number of operating expenses not applicable to the Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund’s securities holdings to reflect changes in the composition of the Index. In addition, when the Fund uses a representative sampling approach, the Fund may not be as well correlated with the return of the Index as when the Fund purchases all of the securities in the Index in the proportions in which they are represented in the Index.

Non-Diversification Risk. Although the Fund intends to invest in a variety of securities and instruments, the Fund is considered to be non-diversified, which means that it may invest more of its assets in the securities of a single issuer or a smaller number of issuers than if it were a diversified fund. As a result, the Fund may be more exposed to the risks associated with and developments affecting an individual issuer or a smaller number of issuers than a fund that invests more widely. This may increase the Fund’s volatility and cause the performance of a relatively smaller number of issuers to have a greater impact on the Fund’s performance.

Fixed Income Risk. Generally, the value of fixed income securities will change inversely with changes in interest rates. As interest rates rise, the market value of fixed income securities tends to decrease. Conversely, as interest rates fall, the market value of fixed income securities tends to increase. This risk will be greater for long-term securities than for short-term securities. In recent periods, governmental financial regulators, including the U.S. Federal Reserve, have taken steps to increase interest rates. Changes in government intervention may have adverse effects on investments, volatility, and the liquidity of debt markets.

◦Call Risk. During periods of falling interest rates, an issuer of a callable bond held by the Fund may “call” or repay the security prior to its stated maturity, and the Fund may have to reinvest the proceeds at lower interest rates, resulting in a decline in the Fund’s income.

◦Credit Risk. Credit risk refers to the possibility that the issuer of a security will not be able to make payments of interest and principal when due. Changes in an issuer’s credit rating or the market’s perception of an issuer’s creditworthiness may also affect the value of an investment in that issuer. Credit risk is heightened to the extent the Fund invests in non-investment grade securities.

◦Event Risk. Event risk is the risk that corporate issuers may undergo restructurings, such as mergers, leveraged buyouts, takeovers, or similar events financed by increased debt. As a result of the added debt, the credit quality and market value of a company’s bonds and/or other debt securities may decline significantly.

◦Extension Risk. When interest rates rise, certain obligations will be paid off by the obligor more slowly than anticipated, causing the value of these securities to fall.

◦Interest Rate Risk. Generally, the value of fixed income securities will change inversely with changes in interest rates. As interest rates rise, the market value of fixed income securities tends to decrease. Conversely, as interest rates fall, the market value of fixed income securities tends to increase. This risk will be greater for long-term securities than for short-term securities. Changes in government intervention may have adverse effects on investments, volatility, and illiquidity in debt markets.

◦Prepayment Risk. When interest rates fall, certain obligations will be paid off by the obligor more quickly than originally anticipated, and the proceeds may have to be invested in securities with lower yields. The Fund investing in such securities will be forced to reinvest this money at lower yields, which can reduce the Fund’s returns.

◦Income Risk. The income from the Fund’s investments may decline because of falling market interest rates. This can result when the Fund invests the proceeds from new share sales, or from matured or called bonds, at market interest rates that are below the Fund’s portfolio current earnings rate.

Pacer Aristotle Pacific Floating Rate High Income ETF | Sector Risk Member

Prospectus [Line Items]

Risk [Text Block]

Sector Risk. Sector risk is the possibility that securities within the same group of industries will decline in price due to sector-specific market or economic developments. If the Fund invests more heavily in a particular sector, the value of its shares may be especially sensitive to factors and economic risks that specifically affect that sector. As a result, the Fund’s share price may fluctuate more widely than the value of shares of a fund that invests in a broader range of industries.

◦Consumer Discretionary Sector Risk. The Fund may invest in companies in the consumer discretionary sector, and therefore the performance of the Fund could be negatively impacted by events affecting this sector. The success of consumer product manufacturers and retailers is tied closely to the performance of domestic and international economies, interest rates, exchange rates, competition, consumer confidence, changes in demographics and consumer preferences. Companies in the consumer discretionary sector depend heavily on disposable household income and consumer spending, and may be strongly affected by social trends and marketing campaigns. These companies may be subject to severe competition, which may have an adverse impact on their profitability.

◦Industrials Sector Risk. The Fund may invest in companies in the industrials sector, and therefore the performance of the Fund could be negatively impacted by events affecting this sector. The industrials sector may be affected by changes in the supply of and demand for products and services, product obsolescence, claims for environmental damage or product liability and general economic conditions, among other factors.

Investments in floating rate loans are typically in the form of an assignment or participation. Investors in a loan participation assume the credit risk associated with the borrower and may assume the credit risk associated with an interposed financial intermediary. Accordingly, if a lead lender becomes insolvent or a loan is foreclosed, the Fund could experience delays in receiving payments or suffer a loss. In an assignment, the Fund effectively becomes a lender under the loan agreement with the same rights and obligations as the assigning bank or other financial intermediary. Accordingly, if the loan is foreclosed, the Fund could become part owner of any collateral, and would bear the costs and liabilities associated with owning and disposing of the collateral. In addition, the floating rate feature of loans means that floating rate loans will not generally experience capital appreciation in a declining interest rate environment. Declines in interest rates may also increase prepayments of debt obligations and require the Fund to invest assets at lower yields. Floating rate loans are also subject to prepayment risk. Such loans may not be considered securities and, therefore, may not be afforded the protections of the federal securities laws.

◦Senior Loans Risk. The risks associated with senior loans are similar to the risks of junk bonds, although senior loans typically are senior and secured, whereas junk bonds often are subordinated and unsecured. Investments in senior loans typically are below investment grade and are considered speculative because of the credit risk of their issuers. Such companies are more likely to default on their payments of interest and principal owed, and such defaults could reduce the Fund’s NAV and income distributions. An economic downturn generally leads to a higher nonpayment rate, and a senior loan may lose significant value before a default occurs. There is no assurance that the liquidation of the collateral would satisfy the claims of the borrower’s obligations in the event of the non-payment of scheduled interest or principal, or that the collateral could be readily liquidated. Economic and other events (whether real or perceived) can reduce the demand for certain senior loans or senior loans generally, which may reduce market prices. Senior loans and other debt securities also are subject to the risk of price declines and to increases in prevailing interest rates, although floating-rate debt

instruments such as senior loans in which the Fund may be expected to invest are substantially less exposed to this risk than fixed-rate debt instruments. No active trading market may exist for certain senior loans, which may impair the ability of the Fund to realize full value in the event of the need to liquidate such assets. Adverse market conditions may impair the liquidity of some actively traded senior loans. Longer interest rate reset periods generally increase fluctuations in value as a result of changes in market interest rates.

◦Covenant-Lite Loan Risk. 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 the Fund’s ability to reprice credit risk associated with the borrower and reduce the Fund’s ability to restructure a problematic loan and mitigate potential loss. As a result, the Fund’s exposure to losses on such investments is increased, especially during a downturn in the credit cycle. A significant portion of floating rate loans may be “covenant-lite” loans.

◦Loan Participation Risk. The Fund may not have a readily available market for loan participation interests and, in some cases, the Fund may have to dispose of such securities at a substantial discount from face value. Loan participations also involve the credit risk associated with the underlying corporate borrower.

CLO Risk. CLOs are typically collateralized by a pool of loans, which may include, among others, domestic and foreign senior secured loans, senior unsecured loans, and subordinate corporate loans, including loans that may be rated below investment grade or equivalent unrated loans. The cash flows from CLOs are split into two or more portions, called tranches, varying in risk and yield. CLO tranches can experience substantial losses due to actual defaults, increased sensitivity to defaults due to collateral default and disappearance of protecting tranches as well as market anticipation of defaults.

Risk [Text Block]

Asset-Backed Securities Risk. Asset-backed securities represent interests in “pools” of assets, including consumer loans or receivables. Movements in interest rates (both increases and decreases) may quickly and significantly reduce the value of certain types of asset-backed securities. Although certain asset-backed securities are guaranteed as to timely payment of interest and principal by a government entity, the market price for such securities is not guaranteed and will fluctuate. The purchase of asset-backed securities issued by non-government entities may entail greater risk than such securities that are issued or guaranteed by a government entity. Asset-backed securities issued by non-government entities may offer higher yields than those issued by government entities, but may also be subject to greater volatility than government issues and can also be subject to greater credit risk and the risk of default on the underlying assets. Investments in asset-backed securities are subject to both extension risk, where borrowers pay off their debt obligations more slowly in times of rising interest rates, and prepayment risk, where borrowers pay off their debt obligations sooner than expected in times of declining interest rates.

Pacer Aristotle Pacific Floating Rate High Income ETF | CMBS Risk Member

Risk [Text Block]

CMBS Risk. The Fund may invest in CMBS. CMBS are not backed by the full faith and credit of the U.S. government and are subject to risk of default on the underlying mortgages. The value of the collateral securing CMBS may decline, be insufficient to meet the obligations of the borrower, or be difficult to liquidate. As a result, CMBS may not be fully collateralized and may decline significantly in value. In addition, commercial mortgage loans are secured by commercial property and are subject to risks of delinquency and foreclosure, and risks of loss. In the event of any default under a mortgage, the Fund will bear a risk of loss of principal to the extent of any deficiency between the value of the collateral and the principal and accrued interest of the commercial mortgage loan. Stressed conditions in the markets for CMBS and mortgage-related assets as well as the broader financial markets have in the past resulted in a temporary but significant contraction in liquidity for CMBS. To the extent that the market for CMBS suffers such a contraction, securities that were previously considered liquid could become temporarily illiquid, and the Adviser may experience delays or difficulty in selling assets at the prices at which the Fund carries such assets, which may result in a loss to the Fund.

High Yield Securities Risk. High yield debt obligations (commonly known as “junk bonds”) are speculative investments and entail greater risk of loss of principal than securities and loans that are investment grade rated because of their greater exposure to credit risk. The high yield market at times is subject to substantial volatility and high yield debt obligations may be less liquid than higher quality securities. As a result, the value of the Fund may be subject to greater volatility than other funds, and the Fund may be exposed to greater tracking risk (described below) than other funds.

Market Risk. An investment in the Fund involves risks similar to those of investing in any fund of equity securities, such as market fluctuations caused by such factors as economic and political developments, changes in interest rates and perceived trends in securities prices. The values of equity securities could decline generally or could underperform other investments. Different types of equity securities tend to go through cycles of out-performance and under-performance in comparison to the general securities markets. In addition, securities may decline in value due to factors affecting the securities markets generally or a specific issuer or market. The Fund is subject to the risk that its investment strategy, the implementation of which is subject to a number of constraints, may not produce the intended results. Market risk refers to the possibility that the market values of securities or other investments that the Fund holds will fall, sometimes rapidly or unpredictably, or fail to rise. Security values may fall or fail to rise because of a variety of actual or perceived factors affecting an issuer (e.g., an unfavorable earnings report), the industry or sector in which it operates, or the market as a whole, which may reduce the value of an investment in the Fund. Accordingly, an investment in the Fund could lose money over short or long periods. The market values of the securities the Fund holds can be affected by changes or perceived changes in U.S. or foreign economies and financial markets, and the liquidity of these securities, among other factors. Although equity securities generally tend to have greater price volatility than debt securities, under certain market conditions, debt securities may have comparable or greater price volatility. In addition, stock prices may be sensitive to rising interest rates, as the cost of capital rises and borrowing costs increase.

Liquidity Risk. Liquidity risk exists when particular investments are difficult to purchase or sell. This can reduce the Fund’s returns because the Fund may be unable to transact at advantageous times or prices. Trading opportunities are more limited for Adjustable Rate Securities that have complex terms or that are not widely held. These features may make it more difficult to sell or buy a security at a favorable price or time. Infrequent trading of securities may also lead to an increase in their price volatility.

Equity Market Risk. The equity securities held in the Fund’s portfolio may experience sudden, unpredictable drops in value or long periods of decline in value. This may occur because of factors that affect securities markets generally or factors affecting specific industries, sectors or companies in which the Fund invests. Common stocks are susceptible to general stock market fluctuations and to volatile increases and decreases in value as market confidence in and perceptions of their issuers change. The Fund’s NAV and market price may fluctuate significantly in response to these and other factors. As a result, an investor could lose money over short or long periods of time.

▪ETF Risks. The Fund is an ETF and, as a result of an ETF’s structure, is exposed to the following risks:

◦Authorized Participants (“APs”), Market Makers, and Liquidity Providers Concentration Risk. The Fund has a limited number of financial institutions that may act as APs. In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, shares of the Fund may trade at a material discount to NAV and possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions.

◦Cash Redemption Risk. The Fund’s investment strategy may require it to redeem Shares for cash or to otherwise include cash as part of its redemption proceeds. The Fund may be required to sell or unwind portfolio investments to obtain the cash needed to distribute redemption proceeds. This may cause the Fund to recognize a capital gain that it might not have recognized if it had made a redemption in-kind. As a result, the Fund may pay out higher annual capital gain distributions than if the in-kind redemption process was used. ETF shares can only be redeemed in creation units by APs. Individual shareholders may only purchase and sell ETF shares on a secondary market.

◦Costs of Buying or Selling Shares of the Fund. Due to the costs of buying or selling shares of the Fund, including brokerage commissions imposed by brokers and bid/ask spreads, frequent trading of shares of the Fund may significantly reduce investment results and an investment in shares of the Fund may not be advisable for investors who anticipate regularly making small investments.

◦Shares of the Fund May Trade at Prices Other Than NAV. As with all ETFs, shares of the Fund may be bought and sold in the secondary market at market prices. The price of shares of the Fund, like the price of all traded securities, will be subject to factors such as supply and demand, as well as the current value of the Fund’s portfolio holdings. Although it is expected that the market price of the shares of the Fund will approximate the Fund’s NAV, there may be times when the market price of the shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount). This risk is heightened in times of market volatility, periods of steep market declines, and periods when there is limited trading activity for shares in the secondary market, in which case such premiums or discounts may be significant. Because securities held by the Fund trade on foreign exchanges that are closed when the Fund’s primary listing exchange is open, the Fund is likely to experience premiums and discounts greater than those of domestic ETFs.

◦Trading. Although shares of the Fund are listed for trading on a national securities exchange, such as NYSE Arca, Inc. (the “Exchange”), and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that shares of the Fund will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of shares of the Fund may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than shares of the Fund, and this could lead to differences between the market price of the shares of the Fund and the underlying value of those shares.

The industrials sector may be affected by changes in the supply of and demand for products and services, product obsolescence, claims for environmental damage or product liability and general economic conditions, among other factors.

◦Information Technology Sector Risk. The Fund may invest in companies in the information technology sector, and therefore the performance of the Fund could be negatively impacted by events affecting this sector. Market or economic factors impacting information technology companies and companies that rely heavily on technological advances could have a significant effect on the value of the Fund’s investments. The value of stocks of information technology companies and companies that rely heavily on technology is particularly vulnerable to rapid changes in technology product cycles, rapid product obsolescence, government regulation and competition, both domestically and internationally, including competition from foreign competitors with lower production costs. Stocks of information technology companies and companies that rely heavily on technology, especially those of smaller, less-seasoned companies, tend to be more volatile than the overall market. Information technology companies are heavily dependent on patent and intellectual property rights, the loss or impairment of which may adversely affect profitability.

Investments in non-U.S. securities also may be subject to withholding or other taxes and may be subject to additional trading, settlement, custodial, and operational risks. These and other factors can make investments in the Fund more volatile and potentially less liquid than other types of investments.

The European financial markets have experienced volatility and adverse trends in recent years and these events have adversely affected the exchange rate of the euro and may continue to significantly affect other European countries. Decreasing imports or exports, changes in governmental or EU regulations on trade, changes in the exchange rate of the euro, the default or threat of default by an EU member country on its sovereign debt, and/or an economic recession in an EU member country may have a significant adverse effect on the economies of EU member countries and their trading partners, including some or all of the European countries in which the Fund invests.

Associated Risks of Data and Digital Revolution Companies. Data and digital revolution companies include companies that develop and provide goods and services related to the transmission of data and communications. Transmission and communications services companies are subject to extensive government regulation. The costs of complying with governmental regulations, delays or failure to receive required regulatory approvals, or the enactment of new adverse regulatory requirements may adversely affect the business of such companies. Such companies are also subject to intense competition and thus affected by mergers or consolidations by and among customers, competition with alternative technologies such as wireless communications (including with 5G and other technologies), product compatibility, consumer preferences, rapid product obsolescence, and research and development of new products. Technological innovations may make the products and services of such companies obsolete.

▪ETF Risks. The Fund is an ETF and, as a result of an ETF’s structure, is exposed to the following risks:

◦Authorized Participants (“APs”), Market Makers, and Liquidity Providers Concentration Risk. The Fund has a limited number of financial institutions that may act as APs. In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, shares of the Fund may trade at a material discount to NAV and possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions.

◦Cash Redemption Risk. The Fund’s investment strategy may require it to redeem Shares for cash or to otherwise include cash as part of its redemption proceeds. The Fund may be required to sell or unwind portfolio investments to obtain the cash needed to distribute redemption proceeds. This may cause the Fund to recognize a capital gain that it might not have recognized if it had made a redemption in-kind. As a result, the Fund may pay out higher annual capital gain distributions than if the in-kind redemption process was used. ETF shares can only be redeemed in creation units by APs. Individual shareholders may only purchase and sell ETF shares on a secondary market.

◦Costs of Buying or Selling Shares of the Fund. Due to the costs of buying or selling shares of the Fund, including brokerage commissions imposed by brokers and bid/ask spreads, frequent trading of shares of the Fund may significantly reduce investment results and an investment in shares of the Fund may not be advisable for investors who anticipate regularly making small investments.

◦Shares of the Fund May Trade at Prices Other Than NAV. As with all ETFs, shares of the Fund may be bought and sold in the secondary market at market prices. The price of shares of the Fund, like the price of all traded securities, will be subject to factors such as supply and demand, as well as the current value of the Fund’s portfolio holdings. Although it is expected that the market price of the shares of the Fund will approximate the

Fund’s NAV, there may be times when the market price of the shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount). This risk is heightened in times of market volatility, periods of steep market declines, and periods when there is limited trading activity for shares in the secondary market, in which case such premiums or discounts may be significant. Because securities held by the Fund trade on foreign exchanges that are closed when the Fund’s primary listing exchange is open, the Fund is likely to experience premiums and discounts greater than those of domestic ETFs.

◦Trading. Although shares of the Fund are listed for trading on a national securities exchange, such as NYSE Arca, Inc. (the “Exchange”), and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that shares of the Fund will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of shares of the Fund may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than shares of the Fund, and this could lead to differences between the market price of the shares of the Fund and the underlying value of those shares.

▪Sector Risk. To the extent the Fund invests more heavily in particular sectors of the economy, its performance will be especially sensitive to developments that significantly affect those sectors.

◦Industrials Sector Risk. The Fund may invest in companies in the industrials sector, and therefore the performance of the Fund could be negatively impacted by events affecting this sector. The industrials sector may be affected by changes in the supply of and demand for products and services, product obsolescence, claims for environmental damage or product liability and general economic conditions, among other factors.

◦Information Technology Sector Risk. The Fund may invest in companies in the information technology sector, and therefore the performance of the Fund could be negatively impacted by events affecting this sector. Market or economic factors impacting information technology companies and companies that rely heavily on technological advances could have a significant effect on the value of the Fund’s investments. The value of stocks of information technology companies and companies that rely heavily on technology is particularly vulnerable to rapid changes in technology product cycles, rapid product obsolescence, government regulation and competition, both domestically and internationally, including competition from foreign competitors with lower production costs. Stocks of information technology companies and companies that rely heavily on technology, especially those of smaller, less-seasoned companies, tend to be more volatile than the overall market. Information technology companies are heavily dependent on patent and intellectual property rights, the loss or impairment of which may adversely affect profitability.

Changes in currency exchange rates and the relative value of non-U.S. currencies will affect the value of the Fund’s investment and the value of your Fund shares.

Foreign Securities Risk. Investments in non-U.S. securities involve certain risks that may not be present with investments in U.S. securities. For example, investments in non-U.S. securities may be subject to risk of loss due to foreign currency fluctuations or to political or economic instability. Investments in non-U.S. securities also may be subject to withholding or other taxes and may be subject to additional trading, settlement, custodial, and operational risks. These and other factors can make investments in the Fund more volatile and potentially less liquid than other types of investments. Foreign securities held by the Fund may trade on markets that are closed when U.S. markets are open, which may lead to a difference in the value of the Fund and the underlying foreign securities.

▪Geographic Concentration Risk. To the extent the Fund invests a significant portion of its assets in the securities of companies of a single country or region, it is more likely to be impacted by events or conditions affecting that country or region.

◦Risks Related to Investing in Canada. The Canadian economy is reliant on the sale of natural resources and commodities, which can pose risks such as the fluctuation of prices and the variability of demand for exportation of such products. Changes in spending on Canadian products by the economies of other countries or changes in any of these economies may cause a significant impact on the Canadian economy.

◦Risks Related to Investing in Europe. The economies and markets of European countries are often closely connected and interdependent, and events in one country in Europe can have an adverse impact on other European countries. The Fund makes investments in securities of issuers that are domiciled in, or have significant operations in, member countries of the European Union (“EU”) that are subject to economic and monetary controls that can adversely affect the Fund’s investments. The European financial markets have experienced volatility and adverse trends in recent years and these events have adversely affected the exchange rate of the euro and may continue to significantly affect other European countries. Decreasing imports or exports, changes in governmental or EU regulations on trade, changes in the exchange rate of the euro, the default or threat of default by an EU member country on its sovereign debt, and/or an economic recession in an EU member country may have a significant adverse effect on the economies of EU member countries and their trading partners, including some or all of the European countries in which the Fund invests.

◦Risks Related to Investing in the United States. The Fund may have significant exposure to investments in the United States. As a result, the Fund may be more susceptible to economic, political, regulatory or other events or conditions affecting issuers within the United States, and may be subject to greater price volatility and risk of loss, than a fund holding more geographically diverse investments.

Associated Risk of Industrials and Logistics Companies. Industrials and Logistics companies support the global supply chain. These companies may be adversely affected by a downturn in economic conditions that can result in decreased demand for shipping, ports, trade routes, and freight. Such companies may also be significantly affected by changes in fuel prices, which may be very volatile, the imposition of tariffs or trade wars, changes in labor relations or availability, labor strikes, insurance costs, commodities prices in general, international politics and conflicts, changes in transportation patterns, changes to shipping and air freight routes, weather patterns and events, including hurricane activity, road conditions, pandemic diseases, the congestion, blockage or shutdown of key routes, ports, and canals, commodity prices, taxes, tariffs, trade wars, imposition of emissions standards and other environment-related rules and regulations, domestic or international politics and conflicts, including war or threat of war, computer and/or software malfunction, logistics interference, piracy, cyber attacks and terrorism. Industrials and Logistics companies may also be highly dependent on aircraft, ships, trucks, heavy machinery, technology, or related equipment from a small number of suppliers, and consequently, issues affecting the availability, reliability, safety, or longevity of such equipment may have a significant effect on the operations and profitability of such companies. In addition, regulatory changes and competition from foreign companies subject to more favorable government regulation may affect the success of these companies.

Non-Diversification Risk. Although the Fund intends to invest in a variety of securities and instruments, the Fund is considered to be non-diversified, which means that it may invest more of its assets in the securities of a single issuer or a smaller number of issuers than if it were a diversified fund. As a result, the Fund may be more exposed to the risks associated with and developments affecting an individual issuer or a smaller number of issuers than a fund that invests more widely. This may increase the Fund’s volatility and cause the performance of a relatively smaller number of issuers to have a greater impact on the Fund’s performance.

◦Shares of the Fund May Trade at Prices Other Than NAV. As with all ETFs, shares of the Fund may be bought and sold in the secondary market at market prices. The price of shares of the Fund, like the price of all traded securities, will be subject to factors such as supply and demand, as well as the current value of the Fund’s portfolio holdings. Although it is expected that the market price of the shares of the Fund will approximate the Fund’s NAV, there may be times when the market price of the shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount). This risk is heightened in times of market volatility, periods of steep market declines, and periods when there is limited trading activity for shares in the secondary market, in which case such premiums or discounts may be significant. Because securities held by the Fund trade on foreign exchanges that are closed when the Fund’s primary listing exchange is open, the Fund is likely to experience premiums and discounts greater than those of domestic ETFs.

The risks of investing in the United Kingdom (UK) have been heightened as a result of Brexit, the formal steps taken by the United Kingdom to exit the EU, which has resulted in increased volatility and triggered political, economic, and legal uncertainty. Although the UK has formally left the EU, uncertainty remains as to the long-term consequences of Brexit and issuers in the UK may experience lower growth as a result.

Foreign Securities Risk. Investments in non-U.S. securities involve certain risks that may not be present with investments in U.S. securities. For example, investments in non-U.S. securities may be subject to risk of loss due to foreign currency fluctuations or to political or economic instability. Investments in non-U.S. securities also may be subject to withholding or other taxes and may be subject to additional trading, settlement, custodial, and operational risks. These and other factors can make investments in the Fund more volatile and potentially less liquid than other types of investments. Foreign securities held by the Fund may trade on markets that are closed when U.S. markets are open, which may lead to a difference in the value of the Fund and the underlying foreign securities.

Geographic Concentration Risk. To the extent the Fund invests a significant portion of its assets in the securities of companies of a single country or region, it is more likely to be impacted by events or conditions affecting that country or region.▪Risks Related to Investing in the United States. The Fund may have significant exposure to investments in the United States. As a result, the Fund may be more susceptible to economic, political, regulatory or other events or conditions affecting issuers within the United States, and may be subject to greater price volatility and risk of loss, than a fund holding more geographically diverse investments.

◦Cash Redemption Risk. The Fund’s investment strategy may require it to redeem Shares for cash or to otherwise include cash as part of its redemption proceeds. The Fund may be required to sell or unwind portfolio investments to obtain the cash needed to distribute redemption proceeds. This may cause the Fund to recognize a capital gain that it might not have recognized if it had made a redemption in-kind. As a result, the Fund may pay out higher annual capital gain distributions than if the in-kind redemption process was used. ETF shares can only be redeemed in creation units by APs. Individual shareholders may only purchase and sell ETF shares on a secondary market.

Non-Diversification Risk. Although the Fund intends to invest in a variety of securities and instruments, the Fund is considered to be non-diversified, which means that it may invest more of its assets in the securities of a single issuer or a smaller number of issuers than if it were a diversified fund. As a result, the Fund may be more exposed to the risks associated with and developments affecting an individual issuer or a smaller number of issuers than a fund that invests more widely. This may increase the Fund’s volatility and cause the performance of a relatively smaller number of issuers to have a greater impact on the Fund’s performance.

Equity Market Risk. The equity securities held in the Fund’s portfolio may experience sudden, unpredictable drops in value or long periods of decline in value. This may occur because of factors that affect securities markets generally or factors affecting specific industries, sectors or companies in which the Fund invests. Common stocks are susceptible to general stock market fluctuations and to volatile increases and decreases in value as market confidence in and perceptions of their issuers change. The Fund’s NAV and market price may fluctuate significantly in response to these and other factors. As a result, an investor could lose money over short or long periods of time.

ETF Risks. The Fund is an ETF and, as a result of an ETF’s structure, is exposed to the following risks:

◦Authorized Participants (“APs”), Market Makers, and Liquidity Providers Concentration Risk. The Fund has a limited number of financial institutions that may act as APs. In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, shares of the Fund may trade at a material discount to NAV and possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions.

◦Cash Redemption Risk. The Fund’s investment strategy may require it to redeem Shares for cash or to otherwise include cash as part of its redemption proceeds. The Fund may be required to sell or unwind portfolio investments to obtain the cash needed to distribute redemption proceeds. This may cause the Fund to recognize a capital gain that it might not have recognized if it had made a redemption in-kind. As a result, the Fund may pay out higher annual capital gain distributions than if the in-kind redemption process was used. ETF shares can only be redeemed in creation units by APs. Individual shareholders may only purchase and sell ETF shares on a secondary market.

◦Costs of Buying or Selling Shares of the Fund. Due to the costs of buying or selling shares of the Fund, including brokerage commissions imposed by brokers and bid/ask spreads, frequent trading of shares of the Fund may significantly reduce investment results and an investment in shares of the Fund may not be advisable for investors who anticipate regularly making small investments.

◦Shares of the Fund May Trade at Prices Other Than NAV. As with all ETFs, shares of the Fund may be bought and sold in the secondary market at market prices. The price of shares of the Fund, like the price of all traded securities, will be subject to factors such as supply and demand, as well as the current value of the Fund’s portfolio holdings. Although it is expected that the market price of the shares of the Fund will approximate the Fund’s NAV, there may be times when the market price of the shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount). This risk is heightened in times of market volatility, periods of steep market declines, and periods when there is limited trading activity for shares in the secondary market, in which case such premiums or discounts may be significant. Because securities held by the Fund trade on foreign exchanges that are closed when the Fund’s primary listing exchange is open, the Fund is likely to experience premiums and discounts greater than those of domestic ETFs.

◦Trading. Although shares of the Fund are listed for trading on a national securities exchange, such as The Nasdaq Stock Market LLC (the “Exchange”), and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that shares of the Fund will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of shares of the Fund may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than shares of the Fund, and this could lead to differences between the market price of the shares of the Fund and the underlying value of those shares.

The value of stocks of information technology companies and companies that rely heavily on technology is particularly vulnerable to rapid changes in technology product cycles, rapid product obsolescence, government regulation and competition, both domestically and internationally, including competition from foreign competitors with lower production costs. Stocks of information technology companies and companies that rely heavily on technology, especially those of smaller, less-seasoned companies, tend to be more volatile than the overall market.

Stocks of information technology companies and companies that rely heavily on technology, especially those of smaller, less-seasoned companies, tend to be more volatile than the overall market.

Cash Redemption Risk. The Fund’s investment strategy may require it to redeem Shares for cash or to otherwise include cash as part of its redemption proceeds.

This may cause the Fund to recognize a capital gain that it might not have recognized if it had made a redemption in-kind. As a result, the Fund may pay out higher annual capital gain distributions than if the in-kind redemption process was used. ETF shares can only be redeemed in creation units by APs. Individual shareholders may only purchase and sell ETF shares on a secondary market.

Risk [Text Block]

Non-Diversification Risk. Although the Fund intends to invest in a variety of securities and instruments, the Fund is considered to be non-diversified, which means that it may invest more of its assets in the securities of a single issuer or a smaller number of issuers than if it were a diversified fund. As a result, the Fund may be more exposed to the risks associated with and developments affecting an individual issuer or a smaller number of issuers than a fund that invests more widely. This may increase the Fund’s volatility and cause the performance of a relatively smaller number of issuers to have a greater impact on the Fund’s performance.
