The Nasdaq Composite closed at 15,041.86, reflecting a gain of 0.1%.   Chip stocks helped lift the S&P 500. Early in the day, news broke that Nvidia would supply chips for the Department of Energy's supercomputer, which pushed the stock up 1.9%. Western Digital jumped 7.8% following a report by The Wall Street Journal, which said the company is in advanced talks to merge with Japanese chipmaker Kioxia Holdings. Micron Technology edged 2.8% higher. Bond yields ticked up, with the yield on the benchmark 10-year Treasury note rising as high as 1.352%. Bank stocks ticked up, too.

Delta Air Lines said it would raise health insurance premiums for unvaccinated employees to cover higher coronavirus costs.
