- Invesco S&P 500 Equal Weight ETF (RSP) has crossed $100 billion in assets under management for the first time, absorbing more than $12 billion in inflows this year.
- RSP has outperformed the market-cap-weighted S&P 500 by roughly 3% year-to-date through August 21, as the equal-weight strategy pulls ahead of its flagship counterpart.
- The Magnificent 7 (Alphabet, Amazon, Apple, Meta, Microsoft, Nvidia, Tesla) — roughly one-third of the S&P 500 — posted flat returns in H1 2026 while the broader index gained 9.3%.
- Concentration risk is the driver: the top 10 names now account for nearly 40% of the S&P 500, with investors questioning whether heavy AI-related capex will pay off, per Nathan Geraci of NovaDius.
- The three biggest cap-weighted ETFs — VOO, IVV, and SPY — still hold close to $3 trillion combined (VOO alone about $1 trillion), dwarfing RSP's $100 billion milestone.
- Beyond RSP, roughly 30 equal-weight ETFs exist, with Cinthia Murphy of VettaFi and Geraci pointing to alternatives like EQAL, QQEW, NOBL, EUSA, EQL, RSPT, QEW, and XBI for sector- or index-specific exposure.
Why it matters: RSP's $100B milestone shows concentration risk is no longer theoretical — investors are actively diversifying away from the Mag 7, which went from driving market gains to flat-lining in H1 2026 while the other 493 S&P 500 stocks did the heavy lifting. The persistent asset gap (RSP at $100B versus $3T in VOO/IVV/SPY) signals the rotation is real but still early, and the cap-weighted mega-funds remain the default holding.
