The iShares S&P Mid-Cap 400 Growth ETF (the Fund ) seeks to track the investment results of an index composed of mid-capitalization U.S. equities that exhibit growth characteristics.
The fund tracks the S&P MidCap 400 Growth Index, which selects mid-cap U.S. stocks exhibiting the strongest growth characteristics as measured by earnings-per-share growth, sales-per-share growth, and price momentum. The fund uses representative sampling, meaning it may not hold all index constituents, so its returns may diverge from the index. The index applies a capping methodology that limits any single holding to a maximum of 23% of the index weight.

What the fund is made of
Percentages are of fund net assets. Rounding, liabilities and short positions can make totals differ from 100%.
| Stocks | 99.87% |
| Cash & short-term | 5.86% |
| Derivatives | 0.00% |
These positions come to 105.73% of the fund's net assets. This counts only what the fund reported holding — the holdings disclosure covers assets, not liabilities such as borrowings — so it is not expected to reconcile to 100%.
Derivatives are shown at market value, not notional exposure.
