Portfolio Turnover [Text Block] rr_PortfolioTurnoverTextBlock

Portfolio Turnover 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 the fund’s 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. During the most recent fiscal year, the fund’s portfolio turnover rate was 43.5% of the average value of its portfolio.

Expense Example Narrative [Text Block] rr_ExpenseExampleNarrativeTextBlock This example is intended to help you compare the cost of investing in the fund with the cost of investing in other funds. The example assumes that you invest $10,000 in the fund for the time periods indicated and then sell all of your shares at the end of those periods, that your investment has a 5% return each year, and that the fund’s fees and expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:
Strategy [Heading] rr_StrategyHeading Principal Investment Strategies
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

The fund normally invests at least 80% of its net assets (plus any borrowings for investment purposes) in U.S. equity securities. The fund relies on MSCI Inc., a third-party provider of benchmark indexes and data services, or another unaffiliated data provider to determine the country assigned to a security. Any derivatives that provide exposure to the investment focus suggested by the fund’s name, or to one or more market risk factors associated with the

investment focus suggested by the fund’s name, are counted (as applicable) toward compliance with the fund’s 80% investment policy.

The strategy attempts to create a portfolio with similar characteristics to the S&P 500 Stock Index® (Index) with the potential to provide excess returns relative to the Index. The fund uses a disciplined portfolio construction process whereby it weights each sector and industry approximately the same as the Index. Within each sector and industry, the weighting of individual fund holdings can vary significantly from their weighting within the Index.

The fund attempts to outperform the Index by overweighting those stocks that are viewed favorably relative to their weighting in the Index, and underweighting or avoiding those stocks that are viewed negatively.

A portfolio oversight team, which includes the portfolio managers, is responsible for the overall structure of the fund and for developing rules for portfolio construction. The portfolio oversight team seeks to take advantage of T. Rowe Price’s fundamental research by assigning equity analysts to select stocks for the fund within industries where they have focused expertise. The equity analysts are responsible for selecting stocks and determining the stocks’ weights within their industry-specific portfolios, subject to the oversight and discretion of the portfolio managers who work closely with the analysts.

The fund generally remains fully invested (less than 5% in cash reserves) and seeks to be sector neutral when compared to the Index. While the majority of assets are invested in large-cap U.S. common stocks, the fund may occasionally have some small- and mid-cap exposure in keeping with the fund’s objective.

At times, the fund may have a significant portion of its assets invested in the same economic sector, such as the information technology sector.

 

The fund is an actively-managed, exchange-traded fund (ETF) that does not disclose portfolio holdings daily. In order to provide market participants with information on the fund’s investments, the fund publishes a “Proxy Portfolio” on its website daily. A Proxy Portfolio is a basket of securities that is designed to closely track the daily performance of the fund’s portfolio holdings. While the Proxy Portfolio includes some of the fund’s holdings, it is not the fund’s actual portfolio. The Proxy Portfolio could be based on a broad-based securities index or the fund’s recently disclosed portfolio holdings. The fund’s Portfolio Overlap is available on the fund’s website daily. The Portfolio Overlap is the percentage weight overlap between the holdings of the prior business day’s Proxy Portfolio compared to the holdings of the fund that formed the basis for the fund’s calculation of net asset value (NAV) at the end of the prior business day.

T. Rowe Price U.S. Equity Research ETF | Proxy portfolio structure  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock

Proxy portfolio structure: The fund does not disclose portfolio holdings daily. The fund uses a Proxy Portfolio, which is a basket of securities that is designed to closely track the daily performance of the fund’s portfolio holdings. The fund may not always effectively construct a proxy portfolio that closely tracks the daily performance of the fund’s portfolio holdings. Because the fund uses a Proxy Portfolio, there is a risk that the fund’s shares may trade at a wider bid-ask spread than shares of ETFs that disclose their portfolio holdings daily. This risk is heightened during periods of market disruption and volatility, and, therefore, may cost you more to trade. Although the fund seeks to benefit from keeping its portfolio information confidential, other traders may attempt to use the Proxy Portfolio and publicly available information, including intraday net asset value (INAV) to identify the fund’s trading strategy, which, if successful, could result in such traders engaging in certain predatory trading practices that may have the potential to harm the fund and its shareholders. Because the fund’s shares are traded in the secondary market, a broker may charge a commission to execute a transaction in shares, and you may incur the cost of the spread between the price at which a dealer will buy shares and the somewhat higher price at which a dealer will sell shares.

T. Rowe Price U.S. Equity Research ETF | Premium/Discount  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock

Premium/Discount: Although the Proxy Portfolio is intended to provide investors with enough information to allow for an effective arbitrage mechanism that will keep the market price of the fund at or close to the underlying NAV per share of the fund, there is a risk (which may increase during periods of market disruption or volatility) that market prices will vary significantly from the underlying NAV per share of the fund. These price differences may be greater for this fund compared to ETFs that disclose portfolio holdings daily because it provides different portfolio holdings information to traders. The adviser will monitor on an ongoing basis how shares trade, including the level of any market price premium or discount to NAV and the bid-ask spreads on market transactions. Each day, the website provides the fund’s Tracking Error, which means the standard deviation over the past three months of the daily proxy spread (i.e., the difference, in percentage terms, between the Proxy Portfolio’s per share NAV and that of the fund at the end of the trading day).

T. Rowe Price U.S. Equity Research ETF | Trading halt  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock

Trading halt: It is possible that an active trading market for the shares will not be maintained, or that trading in the shares will be halted for reasons such as market-wide trading halts or the shares no longer meeting the listing requirements of the listing exchange. If securities representing 10% or more of the fund’s portfolio do not have readily available market quotations, the fund would promptly request the listing exchange to halt trading on the fund. In addition, to the extent T. Rowe Price determines that a security held in a fund’s portfolio but not in the Proxy Portfolio does not have readily available market quotations and such circumstance may affect the reliability of the Proxy Portfolio as an arbitrage vehicle, that information, along with the identity and weighting of that security in the fund’s portfolio, will be publicly disclosed on the fund’s website.

T. Rowe Price U.S. Equity Research ETF | Authorized Participant  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock

Authorized Participant: The fund’s shares may have a limited number of active “Authorized Participants,” which are financial institutions that are able to transact daily with the fund to purchase and redeem a large specified number of shares of the fund. To the extent they cannot or otherwise are unwilling to engage in creation and redemption transactions, and no other Authorized Participant steps in, shares of the fund may trade at a significant discount or premium

to NAV and may face trading halts and delisting from the exchange. During times of market stress, Authorized Participants may be more likely to step away from an ETF that does not disclose holdings daily than a traditional ETF.

T. Rowe Price U.S. Equity Research ETF | ETF shares trading  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock

ETF shares trading: Shares of the fund are listed for trading on a national securities exchange and are bought and sold in the secondary market at market prices. The market prices of shares are expected to fluctuate in response to changes in the fund’s NAV, the value of the fund’s holdings, and supply and demand for shares. Disruptions to creations and redemptions, significant market volatility, potential lack of an active trading market for the shares (including through a trading halt), or other factors may widen bid-ask spreads and result in the shares trading significantly above (at a premium) or below (at a discount) to NAV or to the value of the fund’s holdings. If a shareholder purchases shares at a time when the market price is at a premium to the NAV or sells shares at a time when the market price is at a discount to the NAV, the shareholder may sustain losses.

T. Rowe Price U.S. Equity Research ETF | Market conditions  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock

Market conditions: The value of the fund’s investments may decrease, sometimes rapidly or unexpectedly, due to factors affecting an issuer held by the fund, particular industries, or the overall securities markets. A variety of factors can increase the volatility of the fund’s holdings and markets generally, including economic, political, or regulatory developments, recessions, inflation, rapid interest rate changes, war, military conflict, acts of terrorism, natural disasters, and outbreaks of infectious illnesses or other widespread public health issues (such as the coronavirus pandemic) and related governmental and public responses (including sanctions). Certain events may cause instability across global markets, including reduced liquidity and disruptions in trading markets, while some events may affect certain geographic regions, countries, sectors, and industries more significantly than others. Government intervention in markets may impact interest rates, market volatility, and security pricing. These adverse developments may cause broad declines in market value due to short-term market movements or for significantly longer periods during more prolonged market downturns.

T. Rowe Price U.S. Equity Research ETF | Stock investing  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock

Stock investing: Stocks generally fluctuate in value more than bonds and may decline significantly over short time periods. There is a chance that stock prices overall will decline because stock markets tend to move in cycles, with periods of rising and falling prices. The value of stocks held by the fund may decline due to general weakness or volatility in the stock markets in which the fund invests or because of factors that affect a particular company or industry.

 
T. Rowe Price U.S. Equity Research ETF | Sector exposure  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock

Sector exposure: Issuers in the same economic sector may be similarly affected by economic or market events, making the fund more vulnerable to unfavorable developments in that economic sector than funds that invest more broadly.

T. Rowe Price U.S. Equity Research ETF | Information technology sector  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock

Information technology sector: Information technology companies face intense competition, both domestically and internationally, which may have an adverse effect on their profit margins. Like other technology companies, information technology companies may have limited product lines, markets, financial resources, or personnel.

T. Rowe Price U.S. Equity Research ETF | Index correlation  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock

Index correlation: Because the fund weights each sector and industry approximately the same as the Index, the fund’s ability to broadly reallocate its portfolio due to changes in outlook for a

particular sector or industry is more limited than other actively managed funds with greater flexibility to overweight or underweight certain industries due to changes in market conditions. As a result, the fund’s performance may lag the performance of other actively managed funds with more flexible investment programs.

T. Rowe Price U.S. Equity Research ETF | Large-cap stocks  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock

Large-cap stocks: Securities issued by large-cap companies tend to be less volatile than securities issued by small- and mid-cap companies. However, large-cap companies may not be able to attain the high growth rates of successful small- and mid-cap companies, especially during strong economic periods, and may be unable to respond as quickly to competitive challenges.

T. Rowe Price U.S. Equity Research ETF | Active management  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock

Active management: The fund’s overall investment program and holdings selected by the fund’s investment adviser may underperform the broad markets, relevant indices, or other funds with similar objectives and investment strategies.

T. Rowe Price U.S. Equity Research ETF | Cybersecurity breaches  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock

Cybersecurity breaches: The fund could be harmed by intentional cyberattacks and other cybersecurity breaches, including unauthorized access to the fund’s assets, confidential information, or other proprietary information. In addition, a cybersecurity breach could cause one of the fund’s service providers or financial intermediaries to suffer unauthorized data access, data corruption, or loss of operational functionality.
