The PHLX Semiconductor Sector Index bore the brunt of the session, falling 7.9% in its most volatile stretch since March 2020. This index has seen swings of 5% or more eight times this month alone, highlighting a market increasingly wary of valuations that Goldman Sachs strategists suggest have outpaced the actual discounted value of AI-driven capital revenues. Eric Marshall of Hodges Capital described the shift as a necessary rotation, noting that while demand for AI infrastructure remains intact, even the most aggressive bull markets require periodic cooling to remain sustainable.

Broader market sentiment felt the weight of persistent Federal Reserve anxieties and a strengthening dollar, which climbed to a 52-week high of 101.43. While tech-heavy indices retreated, capital flowed toward defensive sectors and financial institutions; JPMorgan Chase shares gained 0.8%. Elsewhere, corporate realities diverged: Oracle shares slid 5.7% after reporting 21,000 job cuts, and Carnival Corporation warned that regional geopolitical conflicts are disrupting bookings. Meanwhile, energy markets reacted to the easing of U.S. sanctions on Iranian crude, pushing West Texas Intermediate down 0.9% to $73.21 a barrel.
