AI Momentum Stalls as Big Tech Faces Investor Skepticism

A Stalling Engine for Growth

Shares of Advanced Micro Devices tumbled after the chipmaker’s latest financial results failed to satisfy Wall Street’s aggressive forecasts for AI-driven demand. Similarly, Palantir Technologies saw its stock price slide as investors scrutinized the long-term implications of the data analytics firm’s recent performance, suggesting that even robust growth may no longer be enough to sustain record-high valuations.

The cooling sentiment was reflected in the Roundhill Magnificent Seven ETF, which dropped more than 1.5%. The fund, tracking the industry’s largest titans, has now gone more than three months without reaching a new high—marking one of its longest periods of stagnation since the post-pandemic recovery began. Alphabet also experienced volatility; while the Google parent reported strong revenue, its commitment to increasing capital-expenditure targets raised concerns about the rising costs of maintaining an AI edge.

Consolidations and Earnings Misses

Amid the broader sector retreat, Texas Instruments announced a definitive agreement to acquire Silicon Labs in a deal valued at approximately $7.5 billion, including debt. The acquisition aims to bolster the company's wireless technology portfolio, though the announcement did little to offset the day's downward trend in the semiconductor space.

Pressure extended to the gig economy as Uber Technologies shares fell after the company’s fourth-quarter earnings fell short of analyst estimates. According to market data, the miss highlights broader pressure on growth stocks as investors pivot away from speculative bets toward proven bottom-line stability.
