AI Trade Faces a 'No Margin for Error' Moment as Hedge Funds Sell Tech

The two most influential voices on Wall Street’s trading desks spent the same week saying roughly the same thing: the market has bet so heavily on artificial intelligence that it can barely afford a single setback.

Citadel Securities, the market-making arm of Ken Griffin’s hedge fund empire, argued that investors have crowded into AI-related trades to such an extent that any failure of the enormous spending to generate returns would leave little cushion. Nohshad Shah, who leads fixed-income sales for Europe, the Middle East and Africa at the firm, wrote in a research note that the recent sell-off in technology stocks shows investors are becoming far more demanding about whether the huge sums being poured into AI will eventually produce enough profit. With so much of both the economy and the equity market leaning on the AI trade, he wrote, other risks could surface with almost no room for the market to absorb them.

Goldman Sachs offered the trading-floor version of the same concern. Tony Pasquariello, who heads the bank’s hedge-fund client business, told clients that as Wall Street suffered its largest sell-off since July, hedge funds sold technology shares last Thursday at the fastest pace in two years. That, he wrote, has seriously undermined confidence in the trade. The S&P 500 has traded in a range for three months, but beneath that calm surface, he noted, performance has been eroding steadily since the end of June, as the AI trade gives back gains.

For weeks, according to Pasquariello, hedge funds have been cutting both net and gross equity exposure, reducing the size of their bets rather than simply rotating between sectors. When the biggest, most liquid names in the market are the ones being sold, it usually signals that investors are raising cash and lowering risk across the board, not that they have found a new favourite corner of the market.

The backdrop is a spending boom of unusual scale. Technology companies and their suppliers are committing hundreds of billions of dollars to data centres, chips and power capacity on the assumption that demand for AI computing will keep climbing. That spending has been a powerful engine for equity indexes, and it has also made the market unusually dependent on a single theme continuing to deliver.

The warning from Citadel Securities is not that AI spending is wasted. It is that the market has stopped giving companies the benefit of the doubt. Investors are now asking for evidence, quarter by quarter, that the money being spent is turning into revenue and profit. That is a higher bar than the one that applied during the phase when almost any AI announcement was rewarded.

For global investors, the message is that the AI trade has shifted from a story about potential to a test of execution. The same dynamic reaches beyond Wall Street. In Asia, chipmakers, server suppliers and data-centre builders tied to the AI supply chain are sensitive to any sign that American demand is cooling, and Hong Kong’s tech-heavy Hang Seng Index has been volatile as investors weigh AI enthusiasm against valuation concerns. Overnight futures for the index were essentially flat, with the tech sub-index edging slightly higher.

What happens next depends less on new promises than on results. Earnings reports from the largest technology companies will be read for any sign that AI revenue is accelerating fast enough to justify the capital being committed. If it is, the recent selling may look like a healthy reset. If it is not, the market’s lack of tolerance, as described by both Citadel Securities and Goldman Sachs, could turn a narrow range into something sharper.
