Vanguard S&P 500 Value ETF(AMEX:VOOV)

The fund passively invests in the committee-selected S&P 500 (the parent index), with emphasis on value. The underlying index selects stocks from the parent index that exhibit these fundamental value characteristics: (i) book-value-to-price ratio, (ii) earnings-to-price ratio, and (iii) sales-to-price ratio. The fund's portfolio has slightly less value exposure due to the S&P Style Indices methodology that divides 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.
