The S&P 500 is probably the most recognized stock index in the world, and is so ubiquitous that for many investors it just means “the market.” It captures approximately 80% of the US’s entire market capitalization, and nearly $8 trillion of cash is indexed to it.

Exchange-traded funds (ETFs) are marketable securities that track an index or a basket of assets. There are three popular ETFs that track the S&P 500: iShares Core S&P 500 ETF, Vanguard S&P 500 ETF, and SPDR S&P 500 ETF. However, not all of these ETFs are created equal. Below, we provide a side-by-side comparison of these top three ETFs:
