All track the same S&P 500 Index, providing exposure to major companies like Apple and Microsoft. While they appear similar in cost, size, yield, and returns, the key differentiator is their long-term cost, which could influence investment decisions."

# SPY vs. VOO vs. IVV: Which S&P 500 (SPX) ETF Should You Buy?

The SPDR S&P 500 ETF Trust (SPY), Vanguard S&P 500 ETF (VOO), and BlackRock (BLK) iShares Core S&P 500 ETF (IVV) all track the same benchmark — the S&P 500 Index (SPX). In practice, that means investors get exposure to the same companies, including Apple (AAPL), Microsoft (MSFT), and Nvidia (NVDA), regardless of which ETF they pick.
