Fund profile
As filed in the prospectus · 2025 Q3
The iShares Russell Mid-Cap ETF (the Fund ) seeks to track the investment results of an index composed of mid-capitalization U.S. equities.

Because the fund may not hold all index securities, its returns may diverge from the index.

Return profile
Total return as filed — price change plus distributions reinvested · trailing figures to Apr 2026
