BBMC is passively managed to track an index that targets mid-cap companies in the US equity market across various sectors. The index primarily considers stocks that fall between the 85th and 95th percentiles in market-cap of the US investible universe, although, large- and small-cap stocks may be included as well. The equity securities can include common stock, preferred stock, and REITs. As a part of the BetaBuilders suite, BBMC provides plain-vanilla exposure to mid-cap equities and can be used as a core holding or as a complement to BBUS and BBSC which covers the total market and small-cap segments of the US equity market respectively. The fund may invest up to 20% in futures to more closely track the index. The index is rebalanced quarterly.
