Overview

The iShares U.S. Basic Materials ETF (IYM) is a fund managed by iShares that operates within the Materials category, one of 15 funds tracked by ETFValuer in this sector. Currently priced at $178.90 with assets under management totaling $1.41 billion, the fund has achieved an overall rank of #319 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 offers a dividend yield of 1.01%, providing income potential alongside its capital appreciation profile. The combination of a mid-tier rank and moderate asset size suggests a specific level of investor adoption relative to the broader universe of available options. Its position within the top third of its specific category contrasts with its lower standing in the overall tracked universe. These metrics collectively define the fund's current market standing and cost structure for potential investors.

Over the most recent trading day, the fund posted a gain of +0.48%, followed by a stronger weekly return of +2.04%. However, the one-month performance shows a decline of -0.78%, and the three-month period reflects a further drop of -2.64%. A reversal in momentum appears in the six-month window, where returns turned positive at +2.44%, leading into a year-to-date increase of +14.80%. The one-year return accelerated significantly to +22.49%, while the three-year annualized return stands at +38.59%. This pattern indicates a divergence where short-term fluctuations were negative before the fund entered a sustained upward trend over the longer horizons. The data shows a clear shift from recent weakness to robust gains over the past year and three-year period.

The fund 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 swings. A Sharpe ratio of 0.88 suggests the fund has generated a reasonable amount of excess return per unit of risk taken over the measured period. Despite these metrics, the fund experienced a maximum drawdown of -23.62%, highlighting the potential for significant temporary losses during market downturns. This combination of moderate volatility and a beta below 1.0 implies the fund may offer some cushion during market declines, yet the deep drawdown reveals substantial downside risk. The Sharpe ratio indicates that the returns achieved have generally compensated investors for the volatility endured, though the magnitude of the drawdown remains a key risk factor. Investors should consider that while the fund may move less aggressively than the market, it still carries the capacity for sharp declines.

IYM Liquidity, Domicile & Tax Treatment

Liquidity: Quoted bid/ask spread is 7.28% 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.
