VO: Vanguard Morningstar Mid-Cap ETF

What does VO hold?#

This fund owns shares of a few hundred medium-sized US companies. These companies are bigger than small firms but smaller than the giants. Their prices can swing more than the prices of the largest companies.

It tracks the Morningstar US Mid Cap Index. It had 271 holdings as of September 30, 2026, according to Vanguard.

What is the VO expense ratio?#

VO 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 VO done since 2004?#

From January 2004 to October 2026, VO returned about 10.2% a year. Say you put in $10,000 at the start. It would have been worth about $90,144 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 VO’s worst drop?#

A drawdown is how far a fund falls from its last high point. VO’s worst fall was −58.9%, from July 13, 2007 to March 9, 2009. It got back to that high on February 8, 2011.

The chart shows how far below its last high the fund was on each day. Big drops are normal for some funds. They matter because selling during a drop locks in the loss.
