The Iran war has triggered the largest oil disruption in history, sending crude prices above $100 a barrel and creating an unexpected windfall for energy stocks. Phillips 66, Chevron, and Exxon Mobil have logged their best quarters on record as the sector becomes one of the few green performers in the S&P 500.

Wall Street's scramble for traditional energy names extends beyond Iran's de facto blockade of the Strait of Hormuz, which has removed about 10 million barrels of crude from global markets daily. The disruption has pushed Exxon's forward price-to-earnings ratio above that of Nvidia, a rare feat for a traditional energy company. Massive drawdowns from strategic stockpiles in the U.S. and elsewhere will need replenishment.

Adding to the bullish case, America's shale patch shows fresh signs of slowing, raising concerns about future supply constraints. The combination of supply disruptions, inventory rebuilding needs, and production challenges has transformed a flagging industry into a market haven. What was once considered a sleepy, declining sector has suddenly become one of the most attractive investment opportunities in a turbulent market.
