The iShares Russell 2500 ETF (the Fund ) seeks to track the investment results of an index composed of mid- and small-capitalization U.S. equities.
The fund seeks to track the Russell 2500 Index, which comprises approximately 2,500 small- to mid-capitalization U.S. equities, by investing a substantial portion of its assets in an underlying fund rather than holding securities directly. It uses representative sampling, meaning it may not hold all index constituents but selects securities expected to have similar aggregate investment characteristics, market capitalization weightings, and liquidity to the index. Because the fund samples rather than fully replicates the index, its returns may diverge from those of the Russell 2500 Index.

What the fund is made of
Percentages are of fund net assets. Rounding, liabilities and short positions can make totals differ from 100%.
| Stocks | 58.80% |
| Other | 40.99% |
| Cash & short-term | 38.21% |
| Derivatives | 0.00% |
These positions come to 138.00% 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.
