Investment Objective

Portfolio Turnover

Portfolio Turnover [Text Block]

rr_PortfolioTurnoverTextBlock

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund Shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. For the fiscal year ended April 30, 2024, the Fund’s portfolio turnover rate was 77% of the average value of its portfolio.

The following example is intended to help retail investors compare the cost of investing in the Fund with the cost of investing in other funds. It illustrates the hypothetical expenses that such investors would incur over various periods if they were to invest $10,000 in the Fund for the time periods indicated and then redeem all of the Shares at the end of those periods. This example assumes that the Fund provides a return of 5% a year and that operating expenses remain the same.

Strategy [Heading]

rr_StrategyHeading

Principal Investment Strategies of the Fund

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund employs a “passive management” (or indexing) investment approach designed to track the total return performance, before fees and expenses, of the Index. The Index is based on a proprietary methodology developed and maintained by Index Design Group (“IDG” or the “Index Provider”), an affiliate of Pacer Advisors, Inc., the Fund’s investment adviser (the “Adviser”).

The Index


The Index uses an objective, rules-based methodology to provide exposure to large and mid-capitalization U.S. companies with high free cash flow yields. Companies with high free cash flow yields are commonly referred to as “cash cows.” The initial index universe is derived from the component companies of the Russell 1000® Index (excluding financial companies). Component companies of the initial universe are screened based on their market capitalization. The equity securities of the 400 companies with the highest market capitalization are included in the Index. Companies with negative average projected free cash flows or earnings are then removed from the Index universe. The remaining companies are ranked by their free cash flow yield for the trailing twelve month period. The equity securities of the 100 companies with the highest free cash flow yield are included in the Index.						Free Cash Flow (FCF): A company’s cash flow from operations minus capital expenditures. Enterprise Value (EV): A company’s market capitalization plus its debt and minus its cash and cash equivalents. Free Cash Flow Yield: FCF / EV

The Fund’s Investment Strategy

Under normal circumstances, at least 80% of the Fund’s net assets (plus any borrowings for investment purposes) will be invested in U.S.-listed equity securities that are the component securities of the Index. The Fund defines “equity securities” to mean common and preferred stocks, rights, warrants and depositary receipts. The Adviser expects that, over time, the correlation between the Fund’s performance and that of the Index, before fees and expenses, will be 95% or better.

The Fund will generally use a “replication” strategy to achieve its investment objective, meaning it will invest in all of the component securities of the Index in the same approximate proportion as in the Index.

rr_RiskTextBlock

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.

rr_ProspectusLineItems

Pacer US Cash Cows 100 ETF | Equity Market Risk Member

rr_RiskTextBlock

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.

rr_ProspectusLineItems

rr_RiskTextBlock

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 US Cash Cows 100 ETF | ETF Risks, Authorized Participants ("AP"), Market Makers, And Liquidity Providers Concentration Risk Member

rr_RiskTextBlock

▪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 US Cash Cows 100 ETF | Large-Capitalization Investing Risk Member

rr_RiskTextBlock

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.

rr_ProspectusLineItems

Pacer US Cash Cows 100 ETF | Mid-Capitalization Investing Member

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.

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.

rr_ProspectusLineItems

Pacer US Cash Cows 100 ETF | Sector Risk Member

rr_RiskTextBlock

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.

rr_ProspectusLineItems

Pacer US Cash Cows 100 ETF | Sector Risk, Consumer Discretionary Sector Risk Member

rr_RiskTextBlock

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 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.

◦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.

Pacer US Cash Cows 100 ETF | Pacer US Cash Cows 100 Index (reflects no deduction for fees, expenses, or taxes)

rr_RiskTextBlock

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.

The Index


The Index uses an objective, rules-based methodology to provide exposure to small-capitalization U.S. companies with high free cash flow yields. Companies with high free cash flow yields are commonly referred to as “cash cows”. The initial Index universe is derived from the component companies of the S&P United States SmallCap Index. Component companies of the initial universe are screened based on their 3-month average daily trading volume. The equity securities of the companies with a 3-month average daily trading volume in the top 75% of the initial universe are included in the Index. The remaining universe is then screened based on the average projected free cash flows and earnings (if available) over each of the next two fiscal years. Companies for which information on their projected free cash flows or earnings is not available will remain in the Index universe. Companies with negative average projected free cash flows or earnings are removed from the Index universe. Equity securities that are not listed for trading on a U.S. securities exchange are excluded from the Index universe. Additionally, financial companies, other than real estate investment trusts (“REITs”), are excluded from the Index universe.						Free Cash Flow (FCF): A company’s cash flow from operations minus capital expenditures. Enterprise Value (EV): A company’s market capitalization plus its debt and minus its cash and cash equivalents. Free Cash Flow Yield: FCF / EV

The remaining companies are ranked by their free cash flow yield for the trailing twelve month period. The equity securities of the 200 companies with the highest free cash flow yield are included in the Index.

At the time of each rebalance of the Index, the companies included in the Index are weighted in proportion to their trailing twelve month free cash flow, and weightings are capped at the lesser of (i) 2% or (ii) a percentage equal to 5% of a company’s free float market capitalization, assuming Index market capitalization of $20 billion. Weight above the 2% foregoing limitation is redistributed among the other Index constituents in proportion to their weights. As of January 31, 2025, the companies included in the Index had a market capitalization of $374 million to $7.7 billion. From time to time, the Index may include more or less than 200 companies as a result of events such as acquisitions, spinoffs and other corporate actions. The Index is reconstituted and rebalanced quarterly as of the close of business on the 3rd Friday of March, June, September, and December based on data as of the 2nd Friday of the applicable rebalance month and will be completed over the next five days.

The Fund’s Investment Strategy

Under normal circumstances, at least 80% of the Fund’s net assets (plus any borrowings for investment purposes) will be invested in U.S.-listed small-capitalization equity securities that are the component securities of the Index. The Fund considers “small-capitalization” companies to be companies within the S&P United States SmallCap Index, and the Fund defines “equity securities” to mean common and preferred stocks, rights, warrants and depositary receipts. The Adviser expects that, over time, the correlation between the Fund’s performance and that of the Index, before fees and expenses, will be 95% or better.”

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.
