The Fund seeks investment results that closely correspond, before fees and expenses, to the performance of the Morningstar US Mid Cap Target Market Exposure Extended Index SM .
The fund tracks the Morningstar US Mid Cap Target Market Exposure Extended Index, which targets securities in the 85th to 95th percentiles of market capitalization and includes mid-cap companies alongside large- and small-cap holdings. The fund invests at least 80% of assets in index constituents, rebalancing quarterly and using representative sampling when necessary, which may result in tracking divergence from the index. Because the fund may operate as non-diversified to the extent the underlying index is non-diversified, it can hold a greater percentage of assets in particular issuers than a diversified fund would.

How it has done
BBMC share class · total returns with dividends reinvested
Volatility over the last 12 months: 12.42%. Past returns are a record, not a forecast.
Jun 2026 and Jul 2026 have been filed since the trailing figures were struck, so they are not in the table above or the curve — every figure here shares one cut-off, which is what makes them comparable with other funds.
