S&P 500, Nasdaq poised for higher open as earnings deluge takes center stage

The S&P 500 and the Nasdaq looked set for a firm open on Tuesday, stabilizing after a commodity rout in the previous session, as investors geared up for ​a flood of corporate results through the week. Palantir Technologies jumped 11.2% in premarket trading after upbeat results highlighted demand ‌for its military-grade AI tools, with U.S. defense spending helping lift quarterly sales. "Palantir's good earnings is helpful for the AI trade," said John Campbell, senior portfolio manager, Allspring Global Investments.
