Overview
The iShares Russell Mid-Cap Value ETF (IWS) is a US Mid Cap fund managed by iShares that currently holds $15.6 billion in assets under management. Trading at a price of $166.48, the fund carries an expense ratio of 0.23% and offers a dividend yield of 0.99%. ETFValuer ranks this ETF #78 out of 458 tracked funds across all categories, assigning it an overall grade of B with a score of 72.2 out of 100. Within its specific category of 14 tracked ETFs, the fund's substantial asset size suggests significant investor adoption relative to the broader universe. The combination of a moderate expense ratio and a nearly 1% yield positions the fund as a cost-effective option for income-focused investors seeking mid-cap value exposure. Its high asset base relative to the category size indicates it is a primary vehicle for accessing this segment of the market.
Over the last trading day, the fund posted a gain of +0.94%, followed by a +0.22% increase over the one-week period. Monthly returns accelerated to +2.02% over one month and further expanded to +7.08% over three months. The upward trajectory continued with a +12.47% return over six months and a +17.45% year-to-date gain. Annual performance reached +22.96% over the last year, while the three-year return total stands at +52.29%. This sequence of figures demonstrates a consistent pattern of positive returns that have strengthened as the investment horizon extends from daily to multi-year periods. The data shows a clear acceleration in performance metrics as the time frame lengthens, moving from single-digit short-term gains to substantial multi-year appreciation.
The fund is assigned a Low volatility label and exhibits a beta of 0.92, indicating that its price movements have historically been slightly less sensitive to broad market fluctuations. A Sharpe ratio of 1.34 suggests the fund has generated a favorable amount of excess return per unit of risk taken over the measured period. Despite the low volatility classification, the maximum drawdown reached -20.57%, reflecting the magnitude of the largest peak-to-trough decline experienced by the fund. This combination of a low beta and a Sharpe ratio above 1.0 implies the fund has managed to deliver returns efficiently while maintaining a defensive posture relative to the market. The -20.57% drawdown figure highlights that even with low volatility characteristics, the fund is subject to significant temporary declines during market stress periods.

IWS Liquidity, Domicile & Tax Treatment
Liquidity: Quoted bid/ask spread is 1.08% and average daily volume is 444K/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 $15.6B provides ample scale, supporting tight spreads and issuer commitment to keep the fund open.
Domicile & tax treatment: IWS 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.
