The State Street SPDR Portfolio S&P 500 Value ETF (SPYV) aims to replicate the overall returns of the S&P 500 Value Index, before deducting its operational expenses. This economical exchange-traded fund offers investors exposure to S&P 500 companies that appear to be trading at an attractive discount compared to the broader market. The selection of stocks for the underlying Index is based on specific "value" attributes, such as their price-to-book, price-to-earnings, and price-to-sales ratios.
