Vanguard U.S. Dividend Appreciation Index ETF seeks to track, to the extent reasonably possible and before fees and expenses, the performance of a U.S. equity index that measures the investment return of common stocks of U.S. companies that have a record of increasing dividends over time. Currently, this Vanguard ETF seeks to track the S&P U.S. Dividend Growers Index (or any successor thereto). It invests directly or indirectly primarily in stocks of U.S. companies.
