S&P 500 and Nasdaq track steepest monthly fall in a year

Major stock indices in the United States faced a sharp downturn on Friday, as persistent anxieties regarding artificial intelligence valuations and unexpected inflation data pressured the technology sector. The Nasdaq Composite and the S&P 500 are currently on track to record their most significant monthly declines since March 2025. This retreat follows a period of intense scrutiny over the massive capital expenditures by major technology firms and the timing of tangible returns on AI investments.

Market volatility has been further stoked by trade policy ambiguity. Following a Supreme Court decision that voided previous duties, a new temporary global tariff of 10% was implemented earlier this week. Amidst this environment, NVIDIA Corporation saw its shares decline by 2.8%, extending losses from the previous session despite reporting robust earnings. The broader information technology sector fell 1.3%, while the financials index dropped more than 2%.

Anthi Tsouvali, a multi-asset strategist at UBS Group AG, highlighted the current uncertainty surrounding the tech industry.

"There are a lot of questions around AI and the impact of AI disruption in different industries and the future of tech and, specifically U.S. tech."

Tsouvali further noted that investors are increasingly rotating toward more traditional and defensive sectors that lack heavy exposure to the information technology space. Earlier on Friday, the brokerage adjusted its recommendation for American equities to neutral, citing high valuations and the limited sensitivity of corporate earnings to global growth trends.

Economic data also weighed on investor sentiment, as producer prices for January rose more than anticipated. This suggests that inflation may remain elevated in the coming months, complicating the outlook for interest rate adjustments. By late morning, the Dow Jones Industrial Average had fallen 632.36 points, or 1.28%, to 48,866.84. The S&P 500 slipped 43.68 points, or 0.63%, to 6,865.18, and the Nasdaq Composite decreased 164.86 points, or 0.72%, to 22,713.52.

Individual stock performance was mixed but dominated by significant moves in the software and media sectors. Zscaler, Inc. saw its stock price plunge 14% after the cloud security provider reported a wider net loss for the second quarter. Conversely, Netflix, Inc. rose 9% as the market reacted positively to the company's decision to end its pursuit of Warner Bros. Discovery, Inc., which saw its shares drop 2%.

In other corporate news, Block, Inc. surged 16% after announcing a major restructuring plan that includes cutting more than 4,000 jobs to better integrate AI across its operations. Dell Technologies Inc. also posted a gain of 16.6% after forecasting that revenue from its AI-optimized server business would double by fiscal year 2027, alongside a commitment to increase shareholder returns.
