How big is the energy sector in the S&P 500?
Energy is the eighth-largest of the 11 sectors in the S&P 500, with a 3.5% weight in the SPDR S&P 500 ETF holdings file on October 1, 2026. Its 20 companies with SEC fundamentals are worth $2.32 trillion, 3.3% of the 497 companies in WealthyBud’s data.
1. Energy is 3.5% of the index by weight and 3.3% by market value
All 21 energy constituents in State Street’s SPY holdings file for October 1, 2026 sum to 3.5%. The 20 with fundamentals hold $2.32 trillion of $70.0 trillion. The measures differ because index weights cover all 501 constituents (not 497) and follow S&P’s methodology. APA has no SEC fundamentals and is left out of shares and medians (WealthyBud data · October 2, 2026).
2. Energy earns 4.3% of net income on 6.8% of revenue
The sector reported $1.23T in revenue and $94.1B in net income in each company’s latest fiscal year. Its profit share is 0.63 times its revenue share (WealthyBud calculation from SEC filings · October 2, 2026).
3. State Street’s energy index has 21 holdings; WealthyBud has fundamentals for 20
The State Street XLE fund page lists 21 holdings under its index characteristics, and XLE tracks the energy sector of the S&P 500. The page gives only the count. APA is in the S&P 500 energy group but has no SEC fundamentals here.

How profitable are energy companies?
The median energy company keeps 10.6% of revenue as net income, below the 12.9% median for the S&P 500. No energy company lost money in the latest fiscal year. Texas Pacific Land had the highest margin at 60.3%, and Valero Energy the lowest at 1.9%.
5. Median net margin: 10.6% for energy, 12.9% for the index
Net margin is GAAP net income divided by revenue for each company’s latest fiscal year, so it includes non-operating gains and losses. The medians cover 20 energy and 497 index companies. Gross margin is n/a: no energy company reports gross profit in this data (WealthyBud data · October 2, 2026).
6. No energy company reported a net loss
All 20 had positive net income in the latest fiscal year. Margins run from 1.9% (VLO) to 60.3% (TPL). At the extremes, operating income exceeds net income for TPL ($592.2M) and VLO ($3.2B) (SEC tag OperatingIncomeLoss), so non-operating items do not explain the margins. (WealthyBud data · October 2, 2026)
| Group | SEC rule | Companies | Revenue | Market cap | Median net margin |
|---|---|---|---|---|---|
| Refiners and integrated majors | SIC 2911 | 6 | $968.0B | $1.59T | 4.9% |
| Exploration and production | SIC 1311 | 6 | $97.2B | $286.7B | 15.2% |
| Pipelines and midstream | SIC 4922–4924 | 4 | $79.5B | $269.2B | 14.7% |
| Oilfield services and equipment | SIC 1389, 3533 | 3 | $85.6B | $155.2B | 9.3% |
| Other energy | all other SIC codes | 1 | $798.2M | $23.3B | 60.3% |
Of the groups with three or more companies, Exploration and production has the highest median net margin (15.2%) and Refiners and integrated majors the lowest (4.9%).
How expensive are energy stocks?
The median energy stock trades at 23.1 times earnings, below the 25.2 median for the S&P 500. Its median price-to-sales ratio is 2.4, versus 3.3. The median debt-to-equity ratio is 0.41, below the index’s 0.66, among companies that report long-term debt.
7. Median P/E: 23.1 for energy, 25.2 for the index
P/E is market cap divided by latest-fiscal-year net income, for companies with positive earnings. The energy median covers 20 of 20 companies (20 profitable) and the index median covers 461 of 497: 27 loss-makers and 9 profitable companies with a withheld P/E (earnings predate a spin-off) are outside the index median. Median price-to-sales (market cap over revenue) is 2.4 for energy (20 companies) and 3.3 for the index (487) (WealthyBud data · October 2, 2026).
8. 1 of 20 profitable energy stocks trades above 50 times earnings
VLO (50.2) sits above that line. The lowest P/E is 10.9 at EXE. P/E uses one year of profit, so it moves with the earnings base (WealthyBud data · October 2, 2026).
9. Median debt-to-equity: 0.41 for energy (19 companies), 0.66 for the index (409)
The ratio is long-term debt divided by year-end parent-company equity, using the long-term-debt tag each company files (the tag differs by company), where equity is positive. 1 of 20 energy companies has no figure (TPL); that does not mean zero debt. The highest is TRGP at 5.43 (WealthyBud data · October 2, 2026).
How fast is energy revenue growing?
The median energy company grew revenue 1.8% in its latest fiscal year, below the 6.9% index median. 4 of 20 energy companies grew revenue more than 20%, and 10 reported lower revenue. Over three years the median compound rate was -3.8% a year.
10. Median revenue growth: 1.8% for energy, 6.9% for the index
Growth compares latest fiscal-year revenue with the year before (2025). The energy median covers 20 companies and the index median 493. The three-year compound rate is -3.8% a year for energy and 5.5% for the index. 10 of 20 energy companies had lower revenue in the latest year, while 4 grew more than 20%: Expand Energy (EXE) at 186%, EQT at 64%, ONEOK (OKE) at 55%, and Diamondback Energy (FANG) at 36%. This page does not test what drove those jumps (WealthyBud data · October 2, 2026).
How do energy dividends compare with the market?
The median trailing dividend yield among 16 energy companies with a yield is 2.10%, above the 1.88% median among 362 index companies with a yield. Trailing means dividends already paid in the last fiscal year divided by today’s price. 9 of 16 of them beat the index median.
11. Median trailing yield: 2.10% for energy, 1.88% for the index
Yield is the latest fiscal year’s dividends per share divided by the current price, so it looks backward and rises when a price falls. The energy median covers 16 of 20 companies; the index median covers 362 of 497. (WealthyBud data · October 2, 2026).
12. 4 of 20 energy companies have no per-share dividend figure and are excluded
Baker Hughes (BKR), Expand Energy (EXE), Halliburton (HAL), and SLB pay dividends in cash-flow data, but EDGAR has no per-share dividend fact for the year, so their yield is blank. The index pool follows the same rule: 369 index companies report a dividend per share above zero, and 7 of them have a withheld yield, including BDX, CMCSA, CTVA, DD, FDX, HON, and SPGI (dividends predate a spin-off) (WealthyBud data · October 2, 2026).
| Company | Trailing yield | Latest fiscal-year dividend per share |
|---|---|---|
| ONEOK (OKE) | 4.71% | $4.12 |
| Kinder Morgan (KMI) | 3.77% | $1.17 |
| Chevron (CVX) | 3.30% | $6.84 |
| Williams (WMB) | 2.86% | $2.00 |
| EOG Resources (EOG) | 2.82% | $3.99 |
13. ONEOK has the highest trailing yield at 4.71%
ONEOK (OKE) leads the 16 energy companies with a yield. Trailing yields can look high after a price drop or dividend cut. All five use the fiscal-year total dividend per share. (WealthyBud data · October 2, 2026).
What do EIA oil price and production figures show?
EIA’s September 2026 Short-Term Energy Outlook lists 2026 average spot prices of $84.65 a barrel for WTI and $91.01 for Brent, after $65.40 and $69.04 in 2025. The same outlook puts 2025 U.S. crude oil production at 13.7 million barrels per day. This page does not test how prices relate to stock results.
14. EIA’s September 2026 outlook lists 2026 WTI at $84.65 and Brent at $91.01 a barrel
Table 2 of the Short-Term Energy Outlook (September 2026, released September 9) lists annual spot averages of $84.65 for WTI and $91.01 for Brent in 2026, and $69.74 and $73.74 for 2027. EIA completed the forecast on September 3, 2026, so the 2026 averages combine reported months with EIA’s forecast for the rest of the year, and 2027 is a forecast. Its overview table labels Brent for 2026 and 2027 “projected.” Prices are not inflation-adjusted.
15. EIA says Brent averaged $91 a barrel in August 2026
EIA’s global oil markets section says “The Brent crude oil spot price increased to an average of $91 per barrel (b) in August, $7/b higher than in July.” The outlook summary forecasts Brent will average “around $90/b” in the second half of 2026 and $74/b in 2027.
16. EIA’s September 2026 outlook puts 2025 U.S. crude oil production at 13.7 million barrels per day
The outlook’s overview table lists 13.7 million b/d for 2025 (Table 4a: 13.66), 13.8 projected for 2026 and 14.3 projected for 2027. An earlier EIA note, Today in Energy of March 31, 2026, said U.S. crude oil production “grew by 3%, or 350,000 barrels per day (b/d), in 2025, setting a new annual production record of 13.6 million b/d.”
