Risk [Text Block]	Equity Market Risk. The securities markets are volatile and the market prices of the Fund’s investments in equity securities may decline generally. Equity securities fluctuate in price based on changes in a company’s financial condition and overall market and economic conditions. Local, regional, or global events such as war, acts of terrorism, the spread of infectious illness or other public health issues, recessions, or other events could have a significant impact on the securities markets and on specific securities. If the market prices of the securities owned by the Fund fall, the value of your investment in the Fund will decline. Volatility in the securities market may make it more difficult for the Fund to accurately value its securities or to sell its securities on a timely basis. Market volatility may also adversely affect the broader economy, which in turn may adversely affect the value of securities owned by the Fund and the net asset value (“NAV”) of its shares.

Risk [Text Block]	Growth Investing Risk. The prices of growth stocks are based largely on projections of the issuer’s future earnings and revenues. If a company’s earnings or revenues fall short of expectations, its stock price may fall dramatically. Growth stocks may be volatile and may also be more expensive, relative to their earnings or assets, compared to value or other stocks. In addition, growth stocks as a group may fall out of favor and underperform the overall equity market.

Risk [Text Block]	ETF Risks. 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. To the extent that (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 such functions, shares may trade at a material discount to NAV, the bid-ask spread could widen, and shares could face trading halts and/or delisting. Costs of Buying or Selling Shares. Due to the costs of buying or selling Fund shares, including brokerage commissions imposed by brokers and bid/ask spreads, frequent trading of Fund shares may significantly reduce investment results and an investment in shares may not be advisable for investors who anticipate regularly making small investments. Shares 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. Although it is expected that the market price of Fund shares will approximate the Fund’s NAV, there may be times when the market price of Fund shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount) due to supply and demand of Fund shares or during periods of market volatility. If an investor buys Fund shares when the shares’ market price is at a premium, the investor may pay more than the shares’ underlying value. If an investor sells Fund shares when the shares’ market price is at a discount, the investor may receive less than the shares’ underlying value. This risk is heightened in times of market volatility, periods of steep market declines, and periods when there is limited trading activity for Fund shares in the secondary market, in which case such premiums or discounts may be significant and the bid-ask spread could widen. Trading. Although Fund shares are listed for trading on the Cboe BZX Exchange, Inc. (the “Exchange”) and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that an active trading market will be maintained for Fund shares or that Fund shares will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of Fund shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Fund shares and could lead to differences between the market price of the Fund’s shares and the underlying value of those shares.

Risk [Text Block]	Market Risk. Financial market risks affect the value of individual instruments in which the Fund invests. When the value of the Fund’s investments goes down, your investment in the Fund decreases in value and you could lose money.

Periods of market volatility may occur in response to market events and other economic, political, and global macro factors (for example, a global pandemic such as COVID-19, the large expansion of government deficits and debt, military conflicts, inflation, and/or recessions). These and other similar events could be prolonged and could adversely affect the value and liquidity of the Fund’s investments and negatively impact the Fund’s performance. Economies and financial markets throughout the world are becoming increasingly interconnected.
