The $100 Oil Trade Is Back, and These 3 ETFs Make It Easy to Profit

WTI crude has rallied higher this month, recovering from a December 2025 trough of $55.44 to sit near $81 per barrel. The catalyst: the death of Iranian Supreme Leader Ayatollah Ali Khamenei on February 28, 2026, which reignited fears of Middle East supply disruption and put the $100 oil thesis back on traders’ radar. Energy equities have responded, with the three most accessible energy ETFs all up more than 25% year-to-date. The question is which one fits your portfolio.

Three Funds, Three Very Different Bets

Energy Select Sector SPDR Fund (NYSEARCA:XLE) is the largest and most liquid of the three, with $33 billion in assets and an expense ratio of 8 basis points. It tracks the S&P 500’s energy members, which means Exxon Mobil and Chevron alone account for roughly 41% of the portfolio. Owning XLE is largely a bet on two of the world’s largest integrated oil companies.

Fidelity MSCI Energy Index ETF (NYSEARCA:FENY) casts the widest net, tracking mid- and small-cap energy names across upstream, midstream, downstream, and services — 115 holdings holdings in all. That breadth has rewarded investors: its one-year return of 35.38% edges out XLE’s 33.54%, suggesting smaller producers have contributed meaningfully to the rally. At an expense ratio of 0.084%, it is also the cheapest way to own the entire sector.

For investors who want direct leverage to oil prices, iShares U.S. Oil & Gas Exploration & Production ETF (NYSEARCA:IEO) is the most targeted option. It focuses on E&P companies whose profits are most directly tied to crude prices, with ConocoPhillips carrying nearly 20% of the portfolio. IEO gained 6.59% in a single week following the geopolitical shock, compared to XLE’s 2.41% over the same stretch.

What You Are Actually Giving Up

XLE’s concentration in integrated majors delivers dividend income and balance-sheet stability, with a dividend yield of 3.44%, but its upside in a sharp oil spike is dampened by Exxon’s diversified refining and chemicals operations. FENY’s breadth works well in sustained rallies but can introduce smaller, less liquid names that underperform when sentiment reverses. IEO’s E&P focus is the most direct oil-price play, but at $461 million in assets it is far smaller and less traded than XLE. Its 0.38% expense ratio reflects the more specialized, actively rebalanced nature of its E&P-only mandate.

XLE’s integrated-major tilt and low fees make it the largest and most liquid option in the group. FENY offers the broadest sector exposure, including smaller producers that have contributed to recent outperformance. IEO’s pure E&P focus makes it the most directly correlated to crude oil prices among the three, with correspondingly higher volatility and a higher expense ratio.
