About IWM
IWM is the best-known fund on smaller US companies. It tracks the Russell 2000, which takes the roughly 2,000 stocks that follow the 1,000 largest in the broad Russell 3000. Small is relative here: many companies in the index are worth several billion dollars.
FTSE Russell rebuilds the index on a fixed calendar. For decades that happened once a year at the end of June, a date that ranks among the busiest trading days on US exchanges because funds adjust their holdings at the same time. From 2026 the schedule moves to twice a year, so that companies are not misclassified for too long between dates.
Smaller companies carry more floating-rate debt on average and depend more on the domestic US market. Their share prices therefore often react more strongly to interest rate changes and economic expectations than those of large corporations. A meaningful share of the companies in the index does not make a profit.
IWM's holdings reports show a large position in a BlackRock money market fund. Behind it is securities lending: the fund lends shares against cash collateral and invests that cash short term. As a result, the reported positions add up to more than 100% of net assets. The comparison in the figures section shows how little IWM shares with a broad market fund such as VTI, measured by weight.
