Your $300,000 in XLE Holds $116,286 in Just Two Oil Companies

You bought State Street Energy Select Sector SPDR ETF (NYSEARCA:XLE) to own the energy sector. On a $300,000 position, $116,286 of that money sits in just two oil companies. That is the hidden cost: diversification you think you own but may not.

Two Companies Hold Nearly 39 Cents of Every Dollar

XLE’s SEC Form N-PORT filing as of June 30, 2026 shows Exxon Mobil (NYSE:XOM | XOM Price Prediction) at 22.67% of net assets and Chevron (NYSE:CVX) at 16.09%. Together they make up 38.76% of the fund. On a $300,000 stake, that works out to $68,015 in Exxon and $48,271 in Chevron.

The drop-off after them is steep. The third-largest holding, ConocoPhillips (NYSE:COP), weighs in at 6.57%, or about $19,701 of the same position. Weights shift as prices move and the fund rebalances, so check XLE’s current holdings before acting on these figures.

A Low Fee Masks a Heavy Two-Stock Tilt

XLE’s expense ratio (shown as a share of assets) is 0.08%, per State Street’s fact sheet. That costs $8 per year per $10,000 invested, or $240 a year on $300,000. Few sector funds charge less. The larger cost here comes from portfolio construction.

Why a Sector Fund Ends Up Top-Heavy

XLE tracks the Energy Select Sector Index, which represents the energy companies inside the S&P 500. The index uses market-cap weighting, meaning each company’s slice depends on its total stock market value, and Exxon and Chevron are the biggest energy companies by that measure, so they get the biggest slices. The fund has held this structure since its December 16, 1998 launch, and its June filing listed just 25 positions.

What Concentration Costs You in Practice

Diversification means spreading money across many holdings so one company’s bad news cannot sink your whole position. XLE has 38.76% in two names. An earnings miss, a refinery outage, a lawsuit, or a costly acquisition at either firm can move XLE far more than the “sector fund” label suggests.

Overlap compounds the problem. Owning Exxon or Chevron directly, or an S&P 500 index fund that holds both, means your true exposure to these two companies is larger than any single account shows. Oil prices add another layer. West Texas Intermediate crude ranged from $83.46 on August 26 to $110.01 on October 19, then settled at $99.64 on November 3.

Exxon and Chevron are large, established businesses, and the tilt has paid off. On an adjusted basis, XLE climbed 174.71% over the past 10 years and 44.83% year to date. Concentration carries risk, but it has also delivered profits. The issue is whether you knowingly chose it.

Lower-Cost Rivals Repeat the Same Tilt

Changing to another market-cap-weighted energy fund mostly produces the same tilt. Fidelity MSCI Energy Index ETF (NYSEARCA:FENY) held Exxon at 21.99% and Chevron at 14.38% as of July 31, 2026, about 36.38% combined. The rest was spread across more small energy names. Its adjusted price gained 158.47% over 10 years, trailing XLE. Investors who want less top-heavy exposure would need an equal-weight energy fund, which gives each company about the same slice. Compare its holdings, fees, and trading volume before assuming it fits.

What This Means for Your Retirement Accounts

Investors at or near retirement should add up their Exxon and Chevron exposure across every account: brokerage, IRA, 401(k), and any S&P 500 fund. Then ask one question. Would you deliberately put that many dollars into two oil companies? If the answer is no, research how an equal-weight energy fund compares with your current allocation. If the answer is yes, you now hold that concentration on purpose.
