Stocks Slide as Wall Street Gets AI Wake-Up Call: Markets Wrap
(Bloomberg) — Wall Street got a reality check as a bruising selloff in several technology giants fueled concern the artificial-intelligence frenzy that has powered the equity bull market might be overblown.
The tech rout engulfed global stocks as worries about frothy valuations ignited a fresh bout of volatility after a nearly three-month surge in riskier assets. The Nasdaq 100 sank 3%. A key gauge of chipmakers, which had doubled from war-driven lows, slid 7%. Losses were more pronounced in Asia, with South Korea’s Kospi plunging 10% from a record. SpaceX climbed after briefly falling below its debut’s open price.
In a rush for safety, Treasuries rose while haven currencies including the Japanese yen and the Swiss franc outperformed. Conversely, Bitcoin lost 3%. Oil dipped, with tankers becoming more overt in transiting the Strait of Hormuz after an interim peace deal between the US and Iran.
Tuesday’s equity pullback comes as the market prepares to close out the first half of the year with some blockbuster gains that had been driven by easing geopolitical tensions, solid earnings and an AI trade revival. But the tech rally has recently faltered on concerns over whether the billions of dollars spent by giant firms will be justified.
“The risk-off trade reflects fear AI exuberance may be overdone,” said Chris Low at FHN Financial.
While warnings about tech euphoria aren’t new, the latest slide was triggered by amplified swings in the world’s best‑performing market this year. What started as a modest drop in South Korea morphed into a plunge that saw foreign investors offloading more than $2.5 billion of Kospi shares.
Market watchers cited a combination of forced liquidation hitting retail investors trading on borrowed money, compounded by a wave of selling tied to leveraged exchange-traded funds tracking SK Hynix Inc. and Samsung Electronics Co.
In addition, a local media report spurred speculation that SK Hynix is slowing expansion of AI memory chip production and shifting emphasis to the cheaper commodity DRAM, fueling worries over demand for AI-data centers.
“It’s going to take quite a bit more weakness in the US market than we’re already seeing to raise any serious warning flags,” said Matt Maley at Miller Tabak. “However, given the level of leverage in South Korea and around the world, investors should guard against being overly complacent.”
Attention will soon shift to Micron Technology Inc.’s results Wednesday, which are expected to provide the clearest test yet of whether demand for AI infrastructure remains strong enough to sustain this year’s rally. Veteran strategist Louis Navellier said the report will be the grand finale to a “stunning” earnings season, noting that every dip should be viewed as a “buying opportunity.”
Tech giants will return to investor favor following a selloff that has dragged down some of the biggest names in recent weeks, Evercore ISI’s Julian Emanuel said. Earnings will be “the proof of the pudding” after driving a “furious rally” in April and May, he told Bloomberg Television’s Surveillance.
“The broader market remains supported by solid fundamentals,” said Brock Weimer at Edward Jones. “We continue to recommend an overweight to equities. However, we believe diversification remains key to managing risk, particularly after the strong gains in technology and other growth-oriented segments of the market.”
Corporate Highlights:
SpaceX has drawn about $89 billion of demand for its debut US bond sale, according to people with knowledge of the matter, setting the stage for one of the biggest deals in the investment-grade market this year. Qualcomm Inc. is in advanced talks to acquire Modular Inc. in a transaction valuing the AI infrastructure software company at about $4 billion, according to people familiar with the matter. Oracle Corp. reduced its workforce by 21,000 employees in the past 12 months, a wider scale than previously known, including those whose jobs were eliminated by the use of artificial intelligence. Goldman Sachs Group Inc. equity traders are on the cusp of setting another record in the second quarter, with that business on track to generate more than $5 billion of revenue, according to people familiar with the matter. What Bloomberg Strategists say…
“The buy-the-dip mentality isn’t dead yet. Given the paucity of news precipitating this pullback, today’s price action has to be seen in that context.”
