The U.S. stock market careened through a manic Monday, going from a steep early loss to a solid gain as worries turned into hope that the war with Iran may not last that long.

Oil prices whipped from nearly $120 per barrel, their highest since 2022, back toward $90. The S&P 500 fell as much as 1.5% before flipping to a gain of 0.8%. The Dow Jones Industrial Average rose 239 points, and the Nasdaq composite climbed 1.4%.

They’re the latest hour-to-hour swings to pummel markets because of uncertainty about how high oil prices will go and how long they will stay there.
