The Invesco S&P MidCap Quality ETF (XMHQ) is designed to mirror the performance of the S&P MidCap 400 Quality Index. The ETF commits at least 90% of its total capital to the individual securities that make up this benchmark index. The index itself utilizes a modified market capitalization weighting approach and consists of roughly 80 companies drawn from the larger S&P MidCap 400 Index. These businesses are identified based on their excellent quality scores, which are determined by a combination of three exclusive factors. Both the ETF and its corresponding index are adjusted twice a year.
