Why is iShares Russell Mid-Cap ETF (IWR) stock moving?
No news items or SEC filings were published about IWR in the 14 days before Nov 10, 2026, so this view rests on price and volume alone. The ETF traded in a roughly 106.85 to 111.63 range over the 14 sessions shown. On Nov 5 it fell about 3.5% (close 107.65 from 111.56) on 2.66M shares, with the close near the session low. It held near 107.8 on Nov 6, then rebounded about 2.7% to 110.74 on Nov 9 on 6.02M shares, the heaviest volume since Nov 4. On Nov 10 it closed at 110.59 on lighter volume of 1.44M, near its VWAP of 110.18. Recent trading sits around the 107 to 111.6 band, and the Nov 9 rebound recovered most of the Nov 5 drop without a clear news driver. Without a catalyst, the picture is neutral, with low confidence.
About iShares Russell Mid-Cap ETF
The iShares Russell Mid-Cap ETF is a BlackRock index fund launched in 2001 that tracks the Russell Midcap Index, which is made up of the roughly 800 smallest companies in the Russell 1000. It has about $55–57 billion in assets, making it one of the largest mid-cap ETFs. It is very diversified: it holds around 820–830 stocks, and the top 10 make up only about 7% of the fund.
How the fund works
The fund tracks the Russell Midcap Index, which weights companies by the value of their publicly traded shares. To do this, it buys a sampled portfolio that closely matches the index. As of fall 2026, its biggest holdings included Marathon Petroleum, Snowflake, Phillips 66, Cloudflare and Datadog, each at roughly 1% or less. Industrials is its largest sector at about 17%, followed by technology and financials. The annual expense ratio is 0.18%. It pays dividends every quarter, with a yield of about 1.2%. It uses no leverage. Because FTSE Russell reconstitutes the index once a year, companies that grow or shrink move in and out of the fund.
