Vanguard Extended Market Index Fund (VEXMX) Diversifiers

Mutual Fund · Currency in USD · Last updated Jul 14, 2026

The investment seeks to track the S&P Completion Index that measures the investment return of small- and mid-capitalization stocks. The fund employs an indexing investment approach designed to track the performance of S&P Completion Index, a broadly diversified index of stocks of small and mid-size U.S. companies. It invests by sampling the index, meaning that it holds a broadly diversified collection of securities that, in the aggregate, approximates the full index in terms of key characteristics. These characteristics include industry weightings and market capitalization, as well as certain financial measures, such as price/earnings ratio and dividend yield.
