S&P 500 Energy stocks: today's ranking and data
The S&P 500 has 21 companies in Energy today. It accounts for 3.4% of the market value of the index companies. Its median P/E is 17.4, against 23.6 for the index as a whole.
What Energy is and what drives its earnings
What it includes. Oil and gas: integrated majors, exploration and production companies, refiners, the pipelines that move and store oil and gas, and oilfield services and equipment. Power utilities are not here (they are in Utilities), and neither are solar-panel makers: in this classification they fall under Technology.
What drives its earnings. Crude oil and natural gas prices, above everything else. In refining, the spread between the cost of crude and the price of gasoline and diesel. In pipelines, volumes shipped, with much steadier fees. And for all of them, capital discipline: how much of what they earn goes into drilling and how much goes back to shareholders.
A word on P/E. With expensive oil, earnings spike and the P/E looks low right at the top of the cycle; with cheap oil, the opposite. In this sector a low P/E can mean peak earnings rather than a cheap stock.
The classification is the one used by this site's data provider, similar to but not the same as GICS, S&P's standard: this sector roughly matches "Energy". Counts may therefore differ from other sources.
All 21 stocks in the sector, by today's multi-factor rank
The rank is the order produced by a quantitative model on data as of Sep 18, 2026: the average of four factors (momentum, value, quality and growth) computed from public data, against the 466 index companies that score. It is a calculation, not a recommendation to buy or sell: it knows nothing about anyone's situation, horizon or risk, and the returns of portfolios built with it are simulated. How it is computed: see the methodology.

The median is the company in the middle: a few firms with near-zero earnings and huge P/Es do not move it, which is what happens to the average. Loss-making companies have no P/E and are left out.
