The Vanguard S&P 500 ETF (VOO) has a lower expense ratio than the SPDR S&P 500 ETF Trust (SPY), making it more cost-efficient for long-term investors. Both funds track the S&P 500 Index with nearly identical sector exposures and performance over one and five years. VOO manages more assets, but neither fund has unique quirks or structural differences.
