The Invesco S&P 500 Minimum Variance ETF (Fund) is based on the S&P 500 Minimum Volatility Index (Index). The Fund will invest at least 90% of its total assets in securities that comprise the Index. The Index employs a managed-volatility methodology that seeks to achieve lower total risk than the S&P 500 Index, while maintaining similar characteristics. Volatility is a statistical measurement of the magnitude of up and down asset price fluctuations over time. The Fund and the Index are rebalanced and reconstituted semi-annually.
