Major U.S. stock indexes recovered considerable ground on Thursday to end higher, despite stumbling early in the session after Russia launched a military assault on Ukraine. The Dow Jones Industrial Average DJIA, +0.28% flipped positive in the final 15 minutes of trade, adding about 90 points, or 0.3%, to end near 33,222. The S&P 500 SPX, +1.50% gained 1.5% and the Nasdaq Composite Index COMP, +3.34% booked a 3.3% gain. The rally came as oil prices CL00, +2.22% climbed and bond yields tumbled, putting the 10-year Treasury rate below 2%. Investors attributed the turnaround for stocks partly to President Joe Biden’s new sanctions imposed Thursday on Russian banks, companies and elites from doing business in western markets, with the aim of cutting short Russian hostilities in Ukraine.
