iShares Core S&P Mid-Cap ETF
U.S. stock index ETF · tracks S&P MidCap 400
The iShares Core S&P Mid-Cap ETF (the Fund ) seeks to track the investment results of an index composed of mid-capitalization U.S. equities.
The fund tracks the S&P MidCap 400 Index using representative sampling, holding a sample of mid-capitalization U.S. equities with similar investment and fundamental characteristics to the index rather than all constituents. Because the fund may not hold all index securities, its returns may diverge from the index it seeks to track.

How it has done
IJH share class · total returns with dividends reinvested
Volatility over the last 12 months: 11.69%. Past returns are a record, not a forecast.
May 2026 and Jun 2026 have been filed since the trailing figures were struck, so they are not in the table above or the curve — every figure here shares one cut-off, which is what makes them comparable with other funds.
