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, 2018, the Fund’s portfolio turnover rate was 3% 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]

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, an affiliate of Pacer Advisors, Inc., the Fund’s investment adviser (the “Adviser”).

The Index

The Index uses an objective, rules-based methodology to implement a systematic trend-following strategy that directs exposure (i) 100% to the NASDAQ-100^® Index (the “NASDAQ-100”), (ii) 50% to the NASDAQ-100 and 50% to 3-Month US Treasury bills, or (iii) 100% to 3-Month US Treasury bills, depending on the relative performance of the NASDAQ-100 Total Return Index (“NASDAQ-100 TR”) and its 200-business day historical simple moving average (the “200-day moving average”). The NASDAQ-100 TR is a total return version of the NASDAQ-100 and reflects the reinvestment of dividends paid by the securities in the NASDAQ-100.

The NASDAQ-100 Index includes approximately 100 of the largest non-financial securities listed on The NASDAQ Stock Market based on market capitalization. The NASDAQ-100 Index comprises securities of companies across major industry groups, including computer, biotechnology, healthcare, telecommunications and transportation. However, it does not contain securities of financial companies, including investment companies. The NASDAQ 100 Index was developed by NASDAQ OMX. There is no minimum market capitalization requirement for inclusion in the NASDAQ-100 Index. Inclusion is determined based on the top 100 largest issuers based on market capitalization meeting all other eligibility requirements. As of June 30, 2018, the range of market capitalizations of companies in the NASDAQ-100 Index was approximately $9.7 billion to $897 billion.

The Index, and consequently the Fund, may stay in any of its three possible positions for an extended period of time. As described below, the Index will change its position based on the following indicators, and each change will become effective on the second business day after the indicator for the change is triggered.

Equity Indicator. When the NASDAQ-100 TR closes above its 200-day moving average for five consecutive business days (the “Equity Indicator”), the exposure of the Index will be 100% to the NASDAQ-100, effective on the second business following the date of the Equity Indicator.

Once the Equity Indicator has been triggered, the exposure of the Index will next change to either be 50% to the NASDAQ-100 and 50% to 3-Month US Treasury bills if the 50/50 Indicator (described below) is triggered or 100% to 3-Month US Treasury bills if both the 50/50 Indicator and the T-Bill Indicator (described below) are triggered simultaneously, effective on the second business day following the date of the indicator(s).

50/50 Indicator. When the NASDAQ-100 TR closes below its 200-day moving average for five consecutive business days (the “50/50 Indicator”), the exposure of the Index will be 50% to the NASDAQ-100 and 50% to 3-Month US Treasury bills, effective on the second business day following the date of the 50/50 Indicator. Following the effectiveness of the 50/50 Indicator, the exposure of the Index may be greater than or less than 50% with respect to the NASDAQ-100 and 3-Month US Treasury bills depending on their respective performance until either the Equity Indicator or T-Bill Indicator (described below) is triggered.

Once the 50/50 Indicator has been triggered, the exposure of the Index will next change to either be 100% to the NASDAQ-100 if the Equity Indicator is triggered or 100% to 3-Month US Treasury bills if the T-Bill Indicator (described below) is triggered, effective on the second business day following the date of the indicator.

T-Bill Indicator. When the NASDAQ-100 TR’s 200-day moving average closes lower than its value from five business days earlier (the “T-Bill Indicator”), the exposure of the Index will be 100% to 3-Month US Treasury bills, effective on the second business day following the date of the T-Bill Indicator.

For example, if today is Wednesday and the NASDAQ-100 TR’s 200-day moving average closes lower than it did on the fifth preceding business day (Wednesday of the preceding week), the T-Bill Indicator is triggered. Unlike the operation of the Equity Indicator and 50/50 Indicator, the closing values on the days in between today and the fifth preceding business day do not affect whether the T-Bill Indicator has been triggered; rather, the T-Bill Indicator simply compares today’s closing value to the closing value five business days earlier. However, the Index will not move directly from 100% exposure to the NASDAQ-100 to 100% exposure to 3-Month US Treasury bills unless the 50/50 Indicator was first triggered following the most recent triggering of the Equity Indicator.

Once the T-Bill Indicator has been triggered, the exposure of the Index will next change to be 100% to the NASDAQ-100 if the Equity Indicator is triggered, effective on the second business day following the date of the indicator. Once the T-Bill Indicator has been triggered, the Index will not return to its 50/50 position unless the Equity Indicator is simultaneously triggered, followed by the 50/50 Indicator being triggered.

The Index aims to mitigate, to some extent, the volatility of the NASDAQ-100 by tracking 3-Month US Treasury bills (instead of the NASDAQ-100) when the NASDAQ-100 TR is in a negative trend.

The Fund’s Investment Strategy

Under normal circumstances, at least 80% of the Fund’s total assets (exclusive of collateral held from securities lending) will be invested in the component securities of the Index. 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.

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.

Risk [Heading]

Principal Risks of Investing in the Fund

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

You can lose money on your investment in the Fund. The Fund is subject to the risks summarized below. Some or all of these risks may adversely affect the Fund’s net asset value per share (“NAV”), trading price, yield, total return and/or ability to meet its objectives. For more information about the risks of investing in the Fund, see the section in the Fund’s prospectus entitled “Additional Information about the Principal Risks of Investing in the Funds.”

■	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.

■	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.

■	Fixed Income Risk. The value of the Fund’s direct or indirect investments in fixed income securities will fluctuate with changes in interest rates. Typically, a rise in interest rates causes a decline in the value of fixed income securities owned by the Fund. On the other hand, if rates fall, the value of the fixed income securities generally increases. The Fund may be subject to a greater risk of rising interest rates due to the current period of historically low rates and the effect of potential government fiscal policy initiatives and resulting market reaction to those initiatives. In general, the market price of fixed income securities with longer maturities will increase or decrease more in response to changes in interest rates than shorter-term securities. The value of the Fund’s direct or indirect investments in fixed income securities may be affected by the inability of issuers to repay principal and interest or illiquidity in debt securities 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.

■	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 markups and other transaction cost 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.

■	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.

■	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.

■	Other Investment Companies Risk. The Fund will incur higher and duplicative expenses when it invests in other investment companies such as exchange traded funds (“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 following risks: (i) the market price of an ETF’s shares may trade above or below their net asset value; (ii) an active trading market for an ETF’s shares may not develop or be maintained; and (iii) trading of an ETF’s shares may be halted for a number of reasons.

■	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.

■	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.

◦

Information Technology Sector Risk. 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.

■	Shares of the Fund May Trade at Prices Other Than NAV. As with all ETFs, Fund shares may be bought and sold in the secondary market at market prices. The price of Fund shares, 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.

■	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.

■	Trend Lag Risk. At least six consecutive trading days will elapse after the NASDAQ-100 TR 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 NASDAQ-100 to 3-Month US Treasury bills (or conversely, from 3-Month US Treasury bills to the NASDAQ-100). As a result, if the NASDAQ-100 TR 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 TR for up to six consecutive trading days (or conversely, if the NASDAQ-100 TR 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 TR 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 NASDAQ-100 TR and does not provide immediate exposure to upward trends and/or volatility in the NASDAQ-100 TR.
