Cost Conscious? Vanguard S&P 500 ETF Tops SPDR Rival

The Vanguard S&P 500 ETF (VOO) is a more cost-effective option than the SPDR S&P 500 ETF (SPY), with an expense ratio of 0.03% compared to SPY's 0.09%. While both funds track the same index and offer similar performance and risk profiles, VOO has grown larger in assets under management since 2010, appealing to long-term investors seeking lower fees. SPY, launched earlier, remains popular with institutional traders due to its high liquidity.
