The U.S. stock market is ticking toward more records as winners of the artificial-intelligence boom keep driving higher. The S&P 500 rose 0.2% Tuesday, a day after setting its latest all-time high. The Dow Jones Industrial Average added 153 points, and the Nasdaq composite gained 0.2%. All three indexes erased modest losses from earlier in the morning. AI chip companies helped drive the market upward, including Broadcom and Nvidia. Marvell Technology leaped toward its best day in three years after Nvidia’s CEO suggested it could be the next company to be worth $1 trillion. Oil prices were relatively steady.
