Overview

The iShares U.S. Utilities ETF (IDU) is a fund managed by iShares that operates within the Utilities category, one of five ETFs tracked by ETFValuer in this sector. Currently holding an overall rank of #345 out of 458 tracked ETFs across all categories, the fund has received an ETFValuer grade of C with a score of 53.7 out of 100. The fund trades at a price of $115.37 and manages assets under management totaling $1.39 billion. Investors can access the fund with an expense ratio of 0.38% while receiving a dividend yield of 1.97%. The asset size of $1.39 billion suggests a moderate level of investor adoption relative to the broader market. This combination of a mid-tier rank and a C grade reflects a neutral standing among its peers in the utilities space.

Over the most recent trading day, the fund declined by 0.28%, following a weekly gain of 1.19%. The one-month return shows a decrease of 1.24%, while the three-month period resulted in a slight loss of 0.56%. A shift to positive momentum appears in the six-month horizon with a return of 6.74%, which aligns with the year-to-date gain of 6.49%. The one-year return stands at 9.18%, indicating a stronger performance over the longer term compared to the recent short-term fluctuations. The three-year return is notably higher at 50.60%, demonstrating significant long-term growth despite the recent volatility. This pattern suggests a divergence where short-term periods have been mixed or negative while the longer-term trajectory remains positive.

The fund carries a low volatility label and a beta of 0.48, indicating that its price movements are generally less sensitive to market fluctuations than the broader market. A Sharpe ratio of 0.29 suggests the fund has generated a modest amount of risk-adjusted return over the measured period. The maximum drawdown recorded for the fund is -14.76%, representing the largest peak-to-trough decline experienced by investors. This combination of a low beta and low volatility label implies the fund tends to move less aggressively than the market in both up and down conditions. However, the negative drawdown figure confirms that the fund is still subject to significant declines during market stress. The low Sharpe ratio indicates that the returns generated have not been particularly high relative to the risks taken.

IDU Liquidity, Domicile & Tax Treatment

Liquidity: Quoted bid/ask spread is 3.45% and average daily volume is 148K/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 $1.39B provides ample scale, supporting tight spreads and issuer commitment to keep the fund open.

Domicile & tax treatment: IDU 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.
