AI Chip Stocks Reverse Course Mid-Session

Semiconductor companies that power AI systems flipped from gains to losses on Tuesday. Micron Technology fell 1.4% after jumping 4% early, then plunging 10% midday. The stock has tripled this year, raising concerns it moved too fast. Marvell Technology dropped 7.6% and Advanced Micro Devices sank 3% after both erased morning gains. The sharp reversals left investors questioning whether AI stocks face a long downturn or simply need to shed excess optimism.

Flex Ltd announced it joined the S&P 500, marking a milestone for the AI infrastructure and manufacturing company. The addition reflects the company’s growth and transformation in the booming AI sector. The company thanked teams and partners worldwide for the achievement. The move comes as several major AI companies race to list on US exchanges at high valuations.

Broader Market Holds Despite Tech Turbulence

The Dow Jones Industrial Average gained 86 points, or 0.2%, while the Nasdaq composite fell 1%. Nearly three of every four S&P 500 stocks rose despite the sharp swings in the overall index. Oil prices fell 3% to $91.45 per barrel, easing energy costs for consumers and businesses. Asian markets rallied on AI dip-buying, following Monday’s trend in the US as investors bought the dip.

IPO Pipeline Adds Pressure to Valuations

OpenAI filed confidential paperwork with US regulators for an initial public offering on Monday. SpaceX’s IPO could happen later this week. These filings add to questions about whether AI companies can justify high valuations in a volatile market. The rush to go public at peak prices may test investor appetite for new listings.
