NEW YORK—Wall Street churned to a mixed finish Tuesday as a long list of worries looms, even if the most pressing crisis seems to be calming as Washington moves to avoid a default on its debt.
The S&P 500 edged up by 0.07, or less than 0.1 percent, to 4,205.52, hovering close to its highest level since August. The Dow Jones Industrial Average slipped 50.56 points, or 0.2 percent, to 33,042.78. The Nasdaq composite, meanwhile, led the market with a 0.3 percent gain as excitement keeps building about artificial intelligence. It rose 41.74 to 13,017.43.
