The Invesco S&P SmallCap Quality ETF is designed to track the performance of the S&P SmallCap 600 Quality Index. This fund commits to allocating at least 90% of its total assets to the securities that make up its underlying index. The index itself is comprised of 120 stocks selected from the broader S&P SmallCap 600 Index, chosen for their leading quality scores. These scores are determined by averaging three key financial metrics: return on equity, accruals ratio, and financial leverage ratio. Both the ETF and its benchmark index are reviewed and adjusted semi-annually, specifically on the third Friday of June and December.
