IWM – iShares Russell 2000 ETF

About IWM

IWM (iShares Russell 2000 ETF) is a small-cap index ETF from iShares (BlackRock). It is not leveraged: it aims to follow its benchmark one-for-one. Its expense ratio is 0.19% a year, according to both the issuer and Yahoo Finance's fund profile.

What it tracks

The Russell 2000 tracks around 2,000 small-capitalisation US companies, a part of the market that large-company indices such as the S&P 500 leave out.

What to keep in mind

IWM gives unleveraged exposure to small US companies and is the 1× counterpart of the leveraged TNA. Small caps can rise and fall faster than large caps, so IWM's daily moves are often larger than SPY's.

What an index ETF does

An index ETF buys the companies in its benchmark in roughly the same proportions, so its value moves with the index, minus fees and small tracking differences. There is no leverage and no daily reset, so returns over a week, a month or a year are close to the index's own return over that period. Spreading money across many companies reduces the impact of any single company, but the whole index can still fall in a broad market decline.
