The investment objective of BlackRock Advantage Small Cap Core Fund (the Fund), a series of BlackRock Funds SM (the Trust), is to seek capital appreciation over the long term.
The fund invests at least 80% of assets in equity securities with market capitalizations similar to those in the Russell 2000 Index, using proprietary quantitative models to identify mispricings and construct a portfolio that over- and under-weights particular stocks relative to the index. Because the fund's returns depend on the accuracy of its forecasting models and security selection, performance may diverge materially from the Russell 2000 Index.

The 4 share classes hold the same portfolio
| Share class | Expense ratio | 1 year | 3 years | 5 years | Worst fall |
|---|---|---|---|---|---|
| 0.50% | +44.78% | +80.86% | +41.69% | -17.44% | |
| 0.75% | +44.42% | +79.57% | +40.00% | -17.51% | |
| 1.50% | +43.31% | +75.61% | +34.79% | -17.75% | |
| 0.45% | +44.86% | +81.20% | +42.09% | -17.40% |
These classes hold the same portfolio, so the 7.30pp spread over 5 years is the cost difference between them — roughly 1.46pp a year — not a difference in what they own.
