Overview
The iShares U.S. Oil & Gas Exploration & Production ETF (IEO) is an Energy sector fund managed by iShares with $516 million in assets under management. Currently trading at $124.49, the fund holds an overall rank of #226 out of 458 tracked ETFs across all categories and has received an ETFValuer grade of C with a score of 60.8. It carries an expense ratio of 0.38% and offers a dividend yield of 2.12%. The fund operates within a category containing 10 ETFs tracked by ETFValuer. Its asset size and price point reflect a specific level of investor adoption relative to the broader market. The combination of its cost structure and yield profile defines its income and expense characteristics for holders. This positioning places it in the middle tier of the overall tracked universe while maintaining a presence in the Energy sector.
Over the last day, the fund declined by 0.43% before recovering to post a 2.45% gain over one week. Monthly returns accelerated significantly to 14.58%, followed by a 7.12% gain over three months. The six-month period saw a substantial increase of 33.47%, contributing to a year-to-date return of 37.99%. Annual performance reached 41.17%, while the three-year return stands at 41.07%. This pattern indicates a strong upward trajectory over the medium to long term despite minor short-term fluctuations. The data shows a divergence where recent short-term gains align with sustained long-term growth. The fund has demonstrated consistent positive returns across all measured horizons from one day to three years.
The fund carries a High volatility label and exhibits a negative beta of -0.11, suggesting its price movements may not strictly correlate with broader market directions. A Sharpe ratio of 1.41 indicates a favorable risk-adjusted return profile relative to the volatility experienced. However, the maximum drawdown of -31.46% highlights the potential for significant temporary losses during market downturns. This combination of high volatility and a negative beta implies the fund behaves differently than the general market, potentially offering diversification benefits. The Sharpe ratio suggests that despite the large drawdown, the returns generated have compensated well for the risk taken. Investors should note that the high volatility and drawdown figures represent the magnitude of price swings rather than a prediction of future performance.

IEO Liquidity, Domicile & Tax Treatment
Liquidity: Quoted bid/ask spread is 2.19% and average daily volume is 79K/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 $516M provides ample scale, supporting tight spreads and issuer commitment to keep the fund open.
Domicile & tax treatment: IEO 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.
