Vanguard Variable Insurance Funds Capital Growth Portfolio (the Fund) seeks to provide long-term capital appreciation.
The fund actively selects large- and mid-capitalization stocks expected to deliver above-average earnings growth that the market has not yet priced in. Because returns depend on the manager's ability to identify undervalued growth opportunities, performance may diverge materially from broad market returns.
