Invesco S&P 500 Equal Weight ETF (RSP) is an exchange-traded fund that seeks to track the performance of the S&P 500 Equal Weight Index, which consists of large-cap U.S. companies with equal weighting across its constituents. The ETF is managed by Invesco and trades under the ticker RSP on NYSE Arca.
Classified as a U.S. equity ETF, RSP aims to reflect, before fees and expenses, the performance of the securities included in the S&P 500 Equal Weight Index. The fund follows a passive management strategy, maintaining a portfolio structured to replicate the index’s equal-weight methodology.
S&P 500 Equal Weight Index assigns the same weight to each constituent, regardless of market capitalization, distinguishing it from the traditional market-cap-weighted S&P 500. The index undergoes periodic reviews and rebalancing to restore equal weighting among holdings, and these adjustments are reflected in the ETF’s portfolio.

Structure and costs
RSP shares trade on the secondary market, while creation and redemption are conducted through authorized participants, helping maintain alignment between the ETF’s market price and its net asset value (NAV).
The fund charges a management fee and does not apply a performance fee. RSP distributes income periodically, primarily in the form of dividends.
History and evolution of the ETF
Invesco S&P 500 Equal Weight ETF was launched in 2003 during the expansion of the ETF industry and increasing interest in alternative index-weighting methodologies.
In recent years, RSP has reflected key shifts in the U.S. equity market, including periods of concentrated performance among large-cap companies, volatility associated with the interest rate tightening cycle that began in 2022, and evolving sector leadership dynamics.
The fund’s behavior has been closely linked to the performance differences between equal-weight and market-cap-weighted strategies.
