Wall Street's best bargains sit in U.S. energy stocks even as the world grapples with a historic oil crisis. After the latest round of earnings, analysts have raised profit expectations for the sector. They now expect S&P 500 energy stocks to generate 58% more earnings per share in 2026 than they did before the Iran war began, according to FactSet.

Yet the sector has barely budged. The energy basket in the S&P 500 trades just 2% higher than before the war, when oil futures hovered around $70 a barrel and the world had a supply glut. Today, crude approaches $100 a barrel and roughly a billion barrels of oil supply has been lost. The market keeps pricing in potential Iran-U.S. negotiations, creating ongoing uncertainty.

This disconnect has created a significant valuation gap. Energy stocks now trade at less than 14 times forward earnings, making them 36% cheaper than the overall index - deeper than the 29% average discount over the past decade. Even more telling, oil majors and U.S. shale producers aren't deviating from their spending plans despite higher prices, meaning no supply surge to cool rates.

For investors without energy exposure, the sector's combination of restrained capital spending, elevated oil prices, and depressed valuations presents a rare opportunity.
