iShares Russell 2000 ETF (IWM) overview
IWM tracks the Russell 2000 index — the 2,000 smallest stocks in the Russell 3000, representing US small-cap equities. AUM ~$60 billion. The leading vehicle for US small-cap exposure and a key benchmark for measuring the broader US economy beyond mega-cap tech.
Why IWM matters
Small caps are more domestically focused than the S&P 500 — only ~20% of Russell 2000 revenue comes from outside the US, vs. ~40% for the S&P 500. This makes IWM the cleanest proxy for the US domestic economy.
Small caps are also more sensitive to interest rates (higher proportion of unprofitable / debt-financed companies) — IWM typically underperforms in rising-rate cycles and outperforms when rates fall.
