US tech stock slide accel­er­ates amid ques­tions over AI value

The Nasdaq 100 fell more than 3% yesterday as hedge funds were said to be unwinding their positions in the ‘Magnificent Seven’ stocks

US tech stocks tumbled fur­ther yes­ter­day as dis­ap­point­ing earn­ings from Amazon and Intel intens­i­fied investor fears about the sus­tain­ab­il­ity of the AI boom.

The Nas­daq 100 dropped 3.7 per cent, fol­low­ing a $500bn rout in Alpha­bet shares on Thursday that sent the tech­heavy index down 1.4 per cent.

The index hit ses­sion lows after the FT repor­ted that Anthropic might no longer tar­get an invest­ment-grade credit rat­ing after its IPO.

The S&P 500 was down 1.9 per cent. Amazon shares sank 2.3 per cent after it pos­ted weaker than expec­ted sales in res­ults after the mar­ket closed on Thursday. Down­beat fore­casts from chip­maker Intel, in which the US gov­ern­ment has a roughly 10 per cent stake, sent its shares down 30 per cent — on track for the com­pany’s worst ses­sion since 1974. The Phil­adelphia Semi­con­ductor index, which tracks the main US chip com­pan­ies, fell 8.2 per cent.

“The com­bin­a­tion of deteri­or­at­ing cash flows and rising cap­ital com­mit­ments means the debate over whether AI returns can ulti­mately jus­tify the scale of invest­ment may not be resolved any time soon,” said Emmanuel Cau, head of European and Apac equity strategy at Barclays.

“The dir­ec­tion of travel into next year should nat­ur­ally be towards slower earn­ings growth” from the big tech­no­logy com­pan­ies, he added.

Crypto-linked stocks were also among yes­ter­day’s worst per­formers fol­low­ing a huge hack on Bin­ance, the world’s largest crypto­cur­rency exchange. Robin­hood fell 9.4 per cent and Coin­base lost 13.2 per cent.

Rising anxi­ety about the sus­tain­ab­il­ity of the AI infra­struc­ture boom risked cre­at­ing a “neg­at­ive feed­back loop” for the tech sec­tor, said ana­lysts at Vital Know­ledge. “Gloomy psy­cho­logy impairs the abil­ity of com­pan­ies to raise debt and equity, which could fur­ther pres­sure data centre spend­ing.”

Investors’ grow­ing anxi­ety over the AI boom hit Asian tech stocks, with Japan’s tech-heavy Nikkei 225 index clos­ing down 2.1 per cent. OpenAI investor Soft­Bank fell 6 per cent, tak­ing its losses from its June peak to 48 per cent.

“The major tech names are enter­ing a no man’s land where they become unin­vestable,” said Neil New­man, Japan equity strategist at Astris Advis­ory in Tokyo. “When heavy­weights like Soft­Bank halve in value over a few months, it is neither a buy nor a sell. Investors will want to simply keep out of the way.”

Sam­sung Elec­tron­ics and SK Hynix, the two biggest memory-chip makers, slid 3 per cent and 7.1 per cent, respect­ively, tak­ing South Korea’s Kospi index 3.5 per cent lower. In Europe, chip­mak­ing giant ASML lost 6.1 per cent and a bas­ket of the region’s tech­no­logy stocks fell 2.8 per cent.

Higher oil prices also weighed on risky assets such as stocks. Brent crude, the inter­na­tional bench­mark, climbed to its highest level since April at $118 a bar­rel as investors feared loom­ing escal­a­tion in the US-Iran con­flict.

Con­cerns about AI spend­ing have grown as prof­it­able com­pan­ies such as Google plough their free cash flow into cap­ital expendit­ure and increas­ingly turn to pub­lic mar­kets to raise more funds. Shares of Google par­ent Alpha­bet fell 13 per cent on Thursday, wip­ing a record $500bn from its mar­ket value after the com­pany repor­ted a second straight quarter of cash burn and revealed “AI mode” searches were threat­en­ing its advert­ising busi­ness.

“Expect­a­tions built into [tech share] prices are being chal­lenged and are now reset­ting,” said Hank Calenti, global mar­kets strategist at SMBC.

Prime broker­age data shows hedge funds had built up big expos­ure to the “Mag­ni­fi­cent Seven” tech stocks head­ing into earn­ings sea­son. Those pos­i­tions are now being viol­ently unwound, accord­ing to Charlie McEl­lig­ott, a strategist at Nomura. “Bonuses are being determ­ined,” he said. “If [a hedge fund] takes a stu­pid draw­down late in the year, in a mar­ket like this, you blow your­self up. You’re incentiv­ised to take risk off the table.”
