Vanguard Mid-Cap ETF Overview

Vanguard Mid-Cap ETF (VO) is a passively managed U.S. Equity Mid-Cap Blend exchange-traded fund (ETF). Vanguard launched the ETF in 2004.

The advisor attempts to replicate the target index by investing all, or substantially all, of its assets in the stocks that make up the index, holding each stock in approximately the same proportion as its weighting in the index.
