XMHQ is a passively-managed portfolio of 80 securities that tracks the S&P mid-cap 400 Quality Index. The equities are selected based on the highest quality score, calculated by the following three equally-weighted fundamental factors: (1) return-on-equity (2) accruals ratio, and (3) financial leverage ratio. The index is being weighted by the total of its quality score multiplied by its market capitalization and is rebalanced semi-annually. Prior to June 24, 2019, the fund traded as Invesco Russell mid-cap Equal Weight ETF (EQWM) and followed the Russell mid-cap Equal Weight Index.
