Overview
iShares Russell 2000 ETF, with a focus on US small-cap stocks, is issued by iShares and is one of the 18 ETFs tracked in its category. The fund holds an overall rank of #77 among the 458 ETFs tracked by ETFValuer, indicating a moderate position in the broader market. With an expense ratio of 0.19%, the fund is relatively cost-effective, and its dividend yield of 0.68% provides a modest income stream for investors. The fund's price of $299.96 and assets under management (AUM) of $80.1B suggest strong investor adoption, as the fund has attracted significant capital and is actively traded.
The performance of iShares Russell 2000 ETF shows a mix of short-term and long-term gains. Over the past year, the fund has seen a return of +34.46%, while over the past three years, it has delivered a robust +67.40%. This indicates a strong upward trend over the long term, with some volatility in the short term, as seen in the 1-month return of +2.69% and the 1-week return of -1.68%. The 1-day return of +0.77% suggests that the fund can exhibit daily fluctuations, but the overall trend is positive and consistent over longer periods.
The volatility label of 'Moderate' and a beta of 1.26 indicate that iShares Russell 2000 ETF is more volatile than the market but not excessively so. The Sharpe ratio of 1.54 suggests that the fund provides a good risk-adjusted return, meaning that the returns are commensurate with the level of risk taken. The maximum drawdown of -27.50% highlights the fund's potential for significant losses during market downturns. This combination of figures implies that the fund is suitable for investors who are willing to accept some volatility in exchange for potentially higher returns, and it may be a good choice for those looking to participate in the growth of small-cap stocks while managing risk through diversification.

IWM Liquidity, Domicile & Tax Treatment
Liquidity: Quoted bid/ask spread is 0.25% and average daily volume is 23.6M/day. Tighter spreads and higher volume mean lower round-trip trading costs; this is a live-market snapshot and can widen during volatile sessions. AUM of $80.1B provides ample scale, supporting tight spreads and issuer commitment to keep the fund open.
Domicile & tax treatment: IWM is a US-domiciled, SEC-registered ('40 Act) exchange-traded fund. Dividends and capital gains distributions are reported to US investors on Form 1099-DIV, and the fund is not subject to the PFIC reporting or UCITS-specific rules that apply to Irish- or Luxembourg-domiciled funds. Non-US investors should note that US-domiciled ETFs are generally subject to 30% US withholding tax on dividends (unless reduced by treaty) and to US estate tax exposure on the position — Irish-domiciled UCITS ETFs tracking the same index often avoid both, which is why non-US residents frequently prefer the UCITS equivalent where one exists. This is general information, not tax advice — consult a tax professional for your situation.
