The iShares Russell 1000 ETF (the Fund ) seeks to track the investment results of an index composed of large- and mid-capitalization U.S. equities.
The fund tracks the Russell 1000 Index, a float-adjusted market-capitalization-weighted index of approximately 1,007 large- and mid-capitalization U.S. equities, using representative sampling to hold a portfolio with similar investment and fundamental characteristics to the index. Because the fund may not hold all index securities, its returns may diverge from the index. A significant portion of the index is concentrated in technology sector securities.

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.
