QVMM is a passively managed ETF that provides exposure to US mid-cap stocks that exhibit factors of quality, vale, and momentum. Securities from S&P mid-cap 400 Index are each assigned quality, value, and momentum factor scores. From the three style scores, a combined multi-factor score is generated from which the top 90% ranking securities are selected. Using a sampling methodology in tracking the index, QVMM invests in a sample of securities that collectively have a similar investment profile to the underlying index. The index is market cap-weighted and rebalanced quarterly.
