The fund offers exposure to the US small-cap value segment. It pulls from the S&P SmallCap 600 Index and screens for companies that exhibit these fundamental value characteristics: book value, earnings, and sales to price ratio. The fund's portfolio has a slightly less value exposure due to the S&P Style Indices methodology that divide the complete market capitalization of each parent index into growth and value segments resulting in a basket of stocks that overlap with core and growth funds. The underlying index is market cap-weighted and undergoes annual rebalance on the third Friday of December. Like all Vanguard ETFs, the fund only discloses its holdings monthly, instead of daily.
