The Vanguard FTSE Social Index Fund Admiral Shares aims to mirror the investment performance of the FTSE US Choice Index. This index is constructed from large and mid-capitalization stocks, weighted by their market value, and is subject to stringent environmental, social, and corporate governance (ESG) screening. The fund employs a passively managed, full-replication strategy, meaning it seeks to hold all the same securities as its benchmark index in similar proportions.
