Key Differences Between RSP and SPLG
RSP (Invesco S&P 500 Equal Weight ETF) is a us large-cap equal weight fund managed by Invesco. RSP holds all 500 stocks in the S&P 500 but gives each one an equal weight of about 0.2%, rather than weighting by market cap. This means smaller S&P 500 companies have the same influence as mega-caps like Apple or Microsoft. The equal-weight approach reduces concentration risk and provides a natural tilt toward mid-cap and value stocks within the S&P 500 universe.
SPLG (SPDR Portfolio S&P 500 ETF) is a us large-cap blend fund managed by State Street. SPLG tracks the S&P 500 Index at an expense ratio of just 0.02%, making it one of the absolute cheapest ways to own America's 500 largest companies. It is the low-cost sibling of the famous SPY ETF, designed specifically for long-term buy-and-hold investors rather than active traders. The lower share price compared to SPY also makes it more accessible for smaller investment amounts.
The most notable differences are in fees (0.20% vs 0.02%), number of holdings (503 vs 503), and 5-year returns (10.00% vs 14.00%).
