- iShares U.S. Oil Equipment & Services ETF (IEZ) is an exchange-traded fund that seeks to track the investment results of the Dow Jones U.S. Select Oil Equipment & Services Index, which measures the performance of U.S. equities in the oil equipment and services sector. The fund invests at least 80% of its assets in index components, including providers of equipment and services used in drilling, completion, production, and maintenance of oil and gas wells; offshore construction and subsea production; and oilfield services such as pressure pumping, well stimulation, cementing, and coiled tubing; as well as directional drilling, logging, and measurement-while-drilling services. Top holdings include Baker Hughes Co (approximately 22%), Schlumberger Ltd (approximately 22%), TechnipFMC plc, NOV Inc, Halliburton Co, ChampionX Corp, Archrock Inc, Noble Corp plc, Weatherford International plc, and Cactus Inc, representing key players in energy services, drilling rigs, subsea equipment, and completions technologies.
Launched on May 1, 2006, and domiciled in the United States as part of iShares Trust, IEZ is managed by BlackRock Fund Advisors with an expense ratio of 0.38% and primarily trades on NYSE Arca. The fund targets institutional and retail investors seeking exposure to the U.S. oilfield services subsector within the broader energy industry, with nearly all assets (over 97%) allocated to U.S. stocks and minimal non-U.S. exposure. Headquartered through its issuer BlackRock in San Francisco at 400 Howard Street, the ETF operates globally via listings but focuses geographically on U.S.-listed equities.
In recent developments, effective September 22, 2025, IEZ's underlying index underwent changes as part of broader iShares Trust adjustments, coinciding with updates to the syndicated line of credit that added certain iShares ETFs as borrowers while removing others, reflecting ongoing portfolio and financing optimizations. The iShares platform, including IEZ, contributed to record net inflows of $153 billion in Q3 2025, pushing total assets past $5 trillion amid strong fixed income and other ETF growth, underscoring BlackRock's parent-level expansions such as the completed acquisitions of HPS Investment Partners ($12 billion in July 2025) and ElmTree Funds. No major product launches, name changes, or reorganizations specific to IEZ were reported in the last 1-2 years, maintaining its non-diversified focus on the volatile oil equipment sector amid fluctuating energy market conditions.
