The Invesco S&P 500 Pure Value ETF, identified by the symbol RPV, is designed to track the performance of the S&P 500 Pure Value Index. This fund is committed to investing a minimum of 90% of its total assets in the underlying securities that make up this index. The index itself aims to capture the returns of companies within the broader S&P 500 universe that prominently display strong "value" characteristics. Its methodology begins by evaluating every security in the S&P 500 and assigning it distinct "style scores" for both value and growth, based on inherent company attributes. The "value score" is derived from three financial ratios: book-value-to-price, earnings-to-price, and sales-to-price. Conversely, the "growth score" considers different factors, such as the three-year growth in sales per share, the three-year ratio of earnings per share change relative to price, and the stock's 12-month price momentum. These individual growth and value scores are then compared (specifically, the growth score divided by the value score) to classify each stock into one of three categories: "deep value," "blend," or "deep growth." Only those stocks designated as "deep value" are ultimately selected for inclusion in the index. Furthermore, these chosen securities are weighted according to their value strength, meaning those with the most compelling value attributes receive a proportionally larger allocation within the index. Both the ETF and its benchmark index undergo a comprehensive rebalancing process on an annual basis.
