On Tuesday, winners of the artificial-intelligence boom kept driving higher, pushing U.S. stocks to more records.

“One thing that stands out in today’s market is how little investors seem willing to pay for protection despite a world overflowing with potential shocks,” Stephen Innes of SPI Asset Management said in a commentary.

The S&P 500 rose 0.1% to 7,609.78 after drifting between small gains and losses through the day. The Dow Jones Industrial Average added 0.4% to 51,307.79, and the Nasdaq composite edged up by less than 0.1% to 27,093.90. All three set all-time highs.

Marvell Technology leaped 32.5% for its best day since its stock began trading in 2000 after Nvidia’s CEO, Jensen Huang, suggested at a conference in Taiwan that Marvell could be “the next trillion-dollar company.” The last company to enter the expanding club of behemoths was Micron Technology, which is likewise riding the AI wave.

The rally has been largely due to strong profit reports from U.S. companies, and to hopes that the United States and Iran will reach a deal to reopen the Strait of Hormuz. That would allow oil to flow freely again from the Persian Gulf and hopefully lower its price.
