Invesco S&P 500 Equal Weight ETF (RSP) is an exchange-traded fund that seeks to track the investment results of the S&P 500 Equal Weight Index by investing at least 90% of its total assets in securities comprising the underlying index, which equally weights all constituents of the S&P 500 Index; this methodology provides balanced exposure across approximately 500 large-cap U.S. stocks, reduces concentration risk compared to traditional market-cap weighted indexes, and tilts toward smaller companies within the S&P 500 universe, with quarterly rebalancing to maintain equal weighting. The ETF offers investors diversified access to the broad U.S. equity market through a passive management style, daily liquidity on the NYSE Arca exchange under the ticker RSP, quarterly dividend distributions, and a net expense ratio of 0.20%. Launched on April 24, 2003, RSP operates primarily in the United States market, domiciled domestically, and is issued and managed by Invesco Ltd., a global asset manager, targeting institutional and retail investors seeking equal-weight large-cap equity exposure.
In recent developments, Invesco aligned its suite of 11 equal-weight sector ETFs with RSP by standardizing tickers to connect them to the flagship fund, effective June 6, enhancing branding consistency across the equal-weight product lineup managing over $7.5 billion in combined assets. In January 2025, Invesco launched the Invesco S&P 500 Equal Weight Swap UCITS ETF, a swap-based replication variant tracking the same index to provide structural advantages like multi-counterparty swaps for European investors, expanding RSP's strategy internationally. These initiatives build on RSP's legacy as the first smart beta ETF, which marked its 20-year anniversary in 2023, amid ongoing institutional interest evidenced by increased holdings from entities like 1st Source Bank in 2025.
