Nasdaq Weakness Shows AI Stocks Are Losing Their Easy Momentum

The Nasdaq has rallied 30% since March, but semiconductor stocks are now declining as investors pivot from questioning AI demand to scrutinizing whether massive infrastructure spending can justify current valuations. Samsung posted a strong earnings beat, yet the positive result failed to lift sentiment across chip names, signaling a shift in how the market is pricing AI exposure.

Positioning in tech has grown crowded after the sharp rally, raising profit-taking risk if upcoming earnings reports disappoint. The selloff in semiconductor stocks—a core driver of the Nasdaq's year-to-date gains—reflects mounting skepticism that AI infrastructure investments will translate into returns that support elevated multiples.

Investor focus has moved from "will AI demand materialize?" to "can these companies monetize it fast enough?" Samsung's earnings strength, typically a bullish signal for the broader chip ecosystem, was met with indifference, underscoring the new scrutiny.
