In brief

U.S. stock indices fell double‑digit percentages on Friday, driven by disappointing earnings from Amazon and Alphabet and concerns that continued AI capital spending may be excessive. The technology sector led the losses, with Intel plummeting 28.58% and SanDisk dropping 13.47% despite beating forecasts. Rising oil prices and hawkish Federal Reserve commentary added to a negative market mood.

U.S. stocks tumbled on Friday, marking a second week of steep falls as investors reacted to disappointing quarterly results from tech giants Amazon and Alphabet and heightened concerns over the sustainability of large‑scale artificial intelligence (AI) capital spending. The Dow Jones Industrial Average dropped 572.25 points, or 1.09 percent, to 51,770.31, the S&P 500 sank 140.32 points, or 1.82 percent, to 7,580.07, and the Nasdaq Composite plunged 747.73 points, or 2.86 percent, to 25,437.

Across the 11 sectors that compose the S&P 500, energy and consumer staples were the only ones to post gains, climbing 1.91 percent and 1.38 percent respectively. Technology, the most heavily weighted sector, was the largest loser, tumbling 4.24 percent. Industrial shares fell 1.57 percent, while semiconductors and hardware stocks suffered the sharpest reversals.

Technology Sector Collapse Spurs Reappraisal of AI Investment

Amazon’s shares slipped 1.41 percent after the company posted a miss on its earnings chief executive’s expectations. Alphabet, the parent of Google, extended a downward trajectory after recording its steepest single‑day percentage drop in more than two decades. The rout reverberated through the semiconductor and hardware space, with Intel’s quarter‑end stock price plummeting 28.58 percent after management’s fourth‑quarter revenue outlook fell far below Wall Street estimates.

Data‑storage firm SanDisk also fell 13.47 percent. The company had reported first‑quarter earnings that outperformed forecasts, yet investors continued to recoil, focusing on its announcement of an eight‑for‑one forward stock split rather than its earnings beat.

Investors have expressed skepticism that continued AI capital expenditures—spent by firms to build cloud infrastructures, specialized processors, and synthetic data pipelines—can be sustained at the current pace. Even while AI tools promise to deliver leaps in productivity, the financial outlay required for their infrastructure may be considered excessive by market participants, according to the broader consensus reflected in the indices’ decline.

Commodity Prices and Monetary Policy Undermine Market Sentiment

Crude oil futures rose more than 2 percent, reflecting growing headline inflation worries. International benchmark Brent crude climbed to 117.64 U.S. dollars per barrel, while West Texas Intermediate crude rose to 104.12 dollars per barrel. Rising commodity prices added pressure to an already fraught market environment.

In the monetary policy arena, hawkish commentary from Federal Reserve officials added fuel to the market’s negative outlook. Federal Reserve Bank of St. Louis President Alberto Musalem cautioned that inflation remains excessively high and broad‑based, emphasizing that the central bank needs to act soon to prevent elevated prices from becoming entrenched.

Federal Reserve Bank of Richmond President Tom Barkin added that monetary policy remains pointed toward higher borrowing costs to rein in persistent inflation against the backdrop of firm demand.

These comments intensified investor anxieties that higher borrowing costs could weigh on corporate earnings, particularly for capital‑intensive technology firms.

The confluence of earnings misses, concerns over AI capital allocation, tighter monetary conditions, and seed market volatility has culminated in a comprehensive sell‑off across technology and related sectors. Despite these headwinds, energy and consumer staples managed modest gains, underscoring the risk‑averse tilt of market participants in the face of uncertain macroeconomic dynamics.
