VOO: Vanguard S&P 500 ETF

What does VOO hold?#

This fund owns shares of about 500 of the biggest companies in the United States. It follows the S&P 500 index, so its value goes up and down with that group of companies. A handful of very large companies make up a big part of the fund.

It tracks the S&P 500 Index. It had 505 holdings as of September 30, 2026, according to Vanguard.

What is the VOO expense ratio?#

VOO charges 0.03% a year. An expense ratio is the yearly fee a fund takes to run itself. On $10,000, a 0.03% fee comes to about $3 a year.

You never get a bill for it. The fund takes the fee out of its own value a little each day.

How has VOO done since 2010?#

From September 2010 to October 2026, VOO returned about 14.8% a year. Say you put in $10,000 at the start. It would have been worth about $92,175 at the end, with every dividend reinvested.

Prices through October 16, 2026. Figures use daily closing prices adjusted for splits, with dividends reinvested. They do not include taxes or the cost of buying and selling. Past results do not tell you what will happen next.

What was VOO’s worst drop?#
