| Factors Affecting Performance [Text Block] | Management's discussion of fund performance The fund's shares gained 15.90% on a net asset value (NAV) basis and 15.97% on a market price basis for the period from June 24, 2025 to May 31, 2026. These results compare with a 24.07% gain for the Russell 1000 Growth Index. For information on returns for additional periods, including the fund lifetime, please refer to capitalgroup.com/ETF-returns What factors influenced results U.S. equities delivered solid returns during the fiscal year, driven by surging artificial intelligence (AI) investment and robust corporate earnings. Large-cap growth stocks led the gains, with mega-cap technology companies among the top contributors to the market. Energy stocks advanced later in the period, reflecting higher oil prices amid escalating Middle East tensions. The U.S. economy remained resilient, underpinned by higher consumer spending. However, a softening labor market prompted the U.S. Federal Reserve to deliver three 25-basis-point rate cuts. Within the fund, most sectors contributed, with information technology being most additive. Communication services, industrials and consumer discretionary were also positive. The health care and consumer staples sectors also posted double-digit gains in the portfolio but had a less meaningful impact on results due to lower exposures in the portfolio. Conversely, the financials sector posted negative returns during the period. Real estate and utilities also declined during the period.
