Three Reasons to Consider S&P 500 Equal Weight

IAUM Article (85)

The Invesco S&P 500 Equal Weight ETF (RSP) equally weights all stocks in the S&P 500 Index, mitigating concentration risk versus the top-heavy cap-weighted parent index. This approach tilts towards the small size factor – as equal weighting naturally overweights the smallest securities in the parent index and underweights the largest – and the value factor, as relative winners are trimmed and relative laggards are added to at the quarterly rebalance back to equal weight. 

Prior to 2023, RSP had outperformed the S&P 500 Index by an average of 1.08% annually at NAV since its launch.1 However, from the beginning of 2023 through December 2025, it returned 12.52% at NAV against the S&P 500’s 22.96%, as gains in the cap-weighted index were dominated by the “Magnificent 7”, driving record concentration, elevated valuations, and increased growth bias.2 Despite this market dynamic, RSP outperformed the S&P 500 in Q3 2024 and Q1 2025 when market breadth improved.

Looking ahead, investors may favor RSP to help mitigate concentration and valuation risk or to capture potential gains from expanding market breadth amid easing geopolitical tensions and Fed policy shifts.

RSP Standardized Performance
There are risks involved with investing in ETFs, including possible loss of money. Shares are not actively managed and are subject to risks similar to those of stocks, including those regarding short selling and margin maintenance requirements. Ordinary brokerage commissions apply. The Fund's return may not match the return of the Underlying Index. The Fund is subject to certain other risks. Please see the current prospectus for more information regarding the risk associated with an investment in the Fund.    
Investments focused in a particular industry or sector, are subject to greater risk, and are more greatly impacted by market volatility, than more diversified investments.    
Stocks of medium-sized companies tend to be more vulnerable to adverse developments, may be more volatile, and may be illiquid or restricted as to resale.    
Shares are not individually redeemable and owners of the Shares may acquire those Shares from the Fund and tender those Shares for redemption to the Fund in Creation Unit aggregations only, typically consisting of 10,000, 20,000, 25,000, 50,000, 80,000, 100,000 or 150,000 Shares.
