Oil prices resumed their rise because of the war with Iran, but U.S. stocks held steadier this time around. The S&P 500 rose 0.2% Tuesday and added to its gain from the day before, which was its biggest since the war began. The Dow Jones Industrial Average climbed 0.1%, and the Nasdaq composite gained 0.5%. It’s a break from the usual playbook since the start of the war, where stock prices have tended to go in the opposite direction of oil prices. Airline stocks climbed after Delta and others raised their forecasts for upcoming revenue. Treasury yields eased.
