The Invesco S&P MidCap Value with Momentum ETF (XMVM) is designed to replicate the performance of the S&P MidCap 400 High Momentum Value Index. The ETF commits to investing at least 90% of its total assets in the securities that make up this benchmark index. The index itself is constructed by selecting 80 companies from the broader S&P MidCap 400 Index that demonstrate superior "value" and "momentum" attributes. Both the Fund and its underlying index undergo a process of rebalancing and reconstitution twice a year, specifically on the third Friday of June and December.
