Invesco S&P Smallcap 600 Pure Value ETF(AMEX:RZV)

RZV provides a pure value take on the S&P SmallCap 600, a market-cap-weighted index that consists of US small-cap companies screened for size, liquidity, and financial viability. Pure value companies are identified as those with the highest value scores measured by book-value-to-price ratio, earnings-to-price ratio, and sales-to-price ratio. Selected securities are then weighted according to their value scores as well and are rebalanced annually. RZVs underlying index is one of S&Ps pure style indices which aim to create specific style-concentrated indices without overlapping constituents, thus providing an exposure to securities exhibiting the strongest style characteristics.
