U.S. stock indexes are drifting higher Tuesday following a mostly encouraging batch of profit reports from big companies.

The S&P 500 was 0.6% higher in early trading, as many markets around the world took tentative steps following Donald Trump's return to the White House on Monday. The Dow Jones Industrial Average was up 188 points, or 0.4%, as of 9:35 a.m. Eastern time, and the Nasdaq composite was 0.5% higher.
