Why is iShares Russell 2000 ETF (IWM) stock moving?

IWM closed at 280.58 on Nov 10, about 1.2% below its Oct 29 close of 284.01 and 1.4% above its Oct 22 close of 276.67. The main event in the window was a sharp selloff on Nov 5, when the ETF fell 4.6% from 284.02 to 270.98 on 50.9M shares, roughly twice the 14-session average of about 25M. Shares then recovered to 282.51 on Nov 9 on 28.9M shares, and recovered about three-quarters of the drop by Nov 10. The only news item, a Nov 3 Benzinga opinion piece, describes a supportive macro backdrop: 3.4% third-quarter GDP growth and a 78-month expansion. It also flags that September real spending stalled, and it does not explain the Nov 5 move. Key levels from the data are support near 270-271, where the Nov 5 and Nov 6 lows sit, and resistance near 284-286, where the Oct 29 and Nov 4 highs sit. The evidence is thin: one opinion article and no company filings, since an ETF files none. The price recovery is constructive, but the heavy-volume Nov 5 selloff shows sellers are still active.

News behind the analysis

About iShares Russell 2000 ETF

US small caps (Russell 2000 Index)

The iShares Russell 2000 ETF is a BlackRock fund, launched in May 2000, that holds the roughly 2,000 smaller US companies in the Russell 2000 Index. It's one of the biggest and most heavily traded small-cap ETFs, with about $75 billion in assets. Traders and investors widely use it as a stand-in for how US small companies are doing.

How the fund works

The fund tries to match the Russell 2000 Index, which FTSE Russell publishes, by holding the stocks in the index. Bigger companies get a bigger share of the fund (market-cap weighting). Like the index, the fund is rebalanced as the index changes. There's no leverage. The yearly fee (expense ratio) is about 0.19%, which is higher than some rival small-cap funds charge. It pays a small dividend four times a year, recently yielding about 1%. Main risks: small-cap stocks tend to swing more than large caps (beta of about 1.25), and many companies in the index are unprofitable or carry a lot of debt.
