The Invesco S&P SmallCap Low Volatility ETF (XSLV) is designed to mirror the performance of the S&P SmallCap 600 Low Volatility Index. This fund typically commits at least 90% of its total capital to the securities that comprise this benchmark index. The underlying index, developed and managed by Standard & Poor's, identifies 120 small-capitalization companies from the broader S&P SmallCap 600 Index. These specific companies are chosen for exhibiting the lowest historical price fluctuations—a measure known as realized volatility—over the preceding twelve-month period. Volatility itself quantifies the degree of up-and-down movement in an asset's price over time. Both the ETF and its index are subject to rebalancing and component updates on a quarterly basis.
