Invesco S&P 500 Pure Value ETF(AMEX:RPV)

RPV offers pure exposure to the large-cap value space, an approach that emphasizes stocks with the strongest sensitivity to value factors and excludes those with middling value signals. Securities within the S&P 500 with the highest value scores (based on book-value-to-price ratio, earnings-to-price ratio, and sales-to-price ratio) are selected for inclusion in the index, and are also weighted proportionally to their scores so that securities with higher value characteristics are given more weight. The Fund employs a full replication method in tracking the Underlying Index. Rebalancing occurs annually.
