The iShares Russell 2000 Growth ETF (the Fund ) seeks to track the investment results of an index composed of small-capitalization U.S. equities that exhibit growth characteristics.
The fund tracks the Russell 2000 Growth Index, a subset of the Russell 2000 composed of small-cap U.S. equities with higher price-to-book ratios, sales growth, and forecasted growth, using representative sampling to hold a portfolio with similar investment characteristics to the index. Because the fund may not hold all index constituents, its returns may diverge from the index. The index applies a capping methodology that limits any single holding to 22.5% of index weight and restricts holdings above 4.5% to 45% in aggregate, and rebalances quarterly.

What the fund is made of
Percentages are of fund net assets. Rounding, liabilities and short positions can make totals differ from 100%.
| Stocks | 99.62% |
| Cash & short-term | 14.76% |
| Other | 0.01% |
| Derivatives | 0.00% |
These positions come to 114.39% 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.

How it has done
IWO share class · total returns with dividends reinvested
Volatility over the last 12 months: 17.91%. Past returns are a record, not a forecast.
Jun 2026 has been filed since the trailing figures were struck, so it is not in the table above or the curve — every figure here shares one cut-off, which is what makes them comparable with other funds.
