Overview

The iShares U.S. Basic Materials ETF (IYM) is a fund managed by iShares that operates within the Materials category, one of 15 ETFs tracked by ETFValuer in this sector. Currently priced at $178.50 with assets under management totaling $1.41 billion, the fund has achieved an overall rank of #316 out of 458 tracked ETFs across all categories. It carries an ETFValuer grade of C, reflecting a score of 55.6 out of 100, while charging an expense ratio of 0.38%. The fund provides a dividend yield of 1.01%, offering income potential alongside its capital appreciation goals. The combination of a mid-tier rank and a moderate asset base suggests a specific level of investor adoption relative to the broader universe of available funds. This profile positions IYM as a specialized vehicle for exposure to the U.S. basic materials sector with a cost structure typical for its issuer.

Short-term performance shows mixed results, with a one-day gain of +0.72% and a one-week increase of +2.62%, followed by a one-month decline of -0.42%. Over the longer horizon, the fund recorded a three-month return of -2.30% before recovering to a six-month gain of +3.46%. Year-to-date performance has been robust at +14.54%, contributing to a one-year return of +22.58%. The three-year return stands at +34.95%, indicating sustained growth over the medium term despite recent volatility. The data reveals a pattern where short-term fluctuations have been offset by stronger gains over the past year and three years. This trajectory suggests that while recent monthly periods have seen some contraction, the fund has maintained positive momentum over extended timeframes.

IYM is assigned a Moderate volatility label and exhibits a beta of 0.88, indicating that its price movements have historically been slightly less sensitive to broad market shifts. The fund's Sharpe ratio of 0.88 suggests a reasonable balance between the returns generated and the risk taken to achieve them. However, the maximum drawdown of -23.62% highlights the potential for significant temporary losses during market downturns. This combination of a beta below 1.0 and a moderate volatility rating implies the fund may offer some cushion during market declines while still participating in upward trends. The substantial drawdown figure serves as a reminder that despite the moderate beta, the fund remains subject to material sector-specific risks that can lead to sharp declines.

IYM Liquidity, Domicile & Tax Treatment

Liquidity: Quoted bid/ask spread is 2.04% and average daily volume is 216K/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 $1.41B provides ample scale, supporting tight spreads and issuer commitment to keep the fund open.

Domicile & tax treatment: IYM 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.
