Equal-Weight S&P 500 ETF Surpasses $100 Billion AUM Amid Growing Interest
In August 2026, the Invesco S&P 500 Equal Weight ETF (RSP) crossed a significant milestone by surpassing $100 billion in assets under management for the first time. This growth has been driven by strong investor interest and outperformance against traditional market-weighted indices like the S&P 500, with RSP leading year-to-date performance by about 3% as of August 21. The shift toward equal-weight ETFs reflects growing concerns over concentration risk in major stock indexes. The so-called Magnificent 7 tech companies—Alphabet (GOOGL), Amazon (AMZN), Apple (AAPL), Meta (META), Microsoft (MSFT), Nvidia (NVDA), and Tesla (TSLA)—have historically dominated the S&P 500 but have recently underperformed. This has led investors to seek more balanced exposure through equal-weight strategies, which allocate equal value across all index components. RSP is one of only about 30 such ETFs in the market and remains significantly smaller than traditional S&P 500 funds like VOO (Vanguard) or SPY. However, its growing popularity signals a broader shift toward smart-beta strategies as investors look to diversify beyond mega-cap concentration.
