Key Takeaways:
The Philadelphia Semiconductor Index tumbled 4.9% on Tuesday, its steepest single-day drop in over a month, as a broad selloff swept through chip and memory stocks.
"The selloff reflects rate sensitivity in high-beta names rather than a collapse in AI demand," said Richard Windsor, founder of Radio Free Mobile. "These are highly valued stocks that have already run a long way, making them much more volatile than the average."
The S&P 500 fell 0.4%, while the Nasdaq 100 dropped 1.8%. The memory chip index sank 6.8%, with Astera Labs plunging 12%, Teradyne losing 10.3%, and Intel sliding 10.1%. Marvell Technology, Western Digital, KLA Corp., Lam Research, and SanDisk each fell at least 7.1%. The tech sector declined 1.8% and industrials lost 1.6%.
The rout comes as traders reassess the durability of the AI-driven rally that has powered the semiconductor sector to record highs this year. The Philadelphia Semiconductor Index remains up more than 120% since September, leaving it vulnerable to profit-taking if hyperscaler capital spending shows signs of slowing.
Energy was the outperforming sector, rising 3.2%, as Chevron gained 3.6% and Diamondback Energy added 4.2%. Gilead Sciences climbed 5.2%, Regeneron Pharmaceuticals rose 4.1%, and Workday advanced 4%, while Thomson Reuters gained 3.2%.
The 10-year Treasury yield was around 4.47%, down from the previous session's close of 4.49%. The U.S. dollar index was little changed at 100.88. West Texas Intermediate crude traded at $68.65 a barrel, while gold futures rose 1.1% to $4,170 an ounce.
The selloff coincided with three catalysts: a sharp decline in semiconductor valuations, a rotation out of growth into defensive and energy names, and positioning adjustments ahead of the start of second-quarter earnings season later this week.
