'They're shooting the generals': AI trade stocks drop as hedge funds rush to protect 2026 gains

Major artificial intelligence stocks tumbled on Thursday as the Nasdaq index sank 5%. Wall Street analysts warned of an institutional shakeout as investors rushed to lock in their profits.

Nomura cross-asset strategist Charlie McElligott described the market reaction by writing that investors are shooting the generals. He noted that the rapid unwinding of popular 2026 thematic stocks has been wild for more than a month. The primary catalyst is not a sudden drop in business quality, but a frantic dash by hedge funds to secure their financial gains before the end of the year. McElligott added that single-name stock moves have been extreme, with momentum trades unwinding so deeply that some trades are nearing a complete round trip of their prior gains.

Semiconductor and hardware companies suffered some of the heaviest losses during the sell-off. Over the past month, shares of Lam Research dropped 36%, while Applied Materials fell 30%. Other major chipmakers also declined over the same period, with Advanced Micro Devices down 22% and Nvidia down 15%.

Investors have been selling crowded momentum trades and moving their money into lagging sectors of the market. Analysts also pointed to concerns about a potential slowdown in the building of artificial intelligence data centers following a Democratic sweep, which added to the selling pressure.

Memory chipmaker Micron fell 17% during the session, pushing its losses over the past month to roughly 38%, though the stock remains up about 140% for the year. Even energy stocks, which performed best earlier in the year, dropped 10% over a five-day span. Gas turbine maker GE Vernova declined 7% on Thursday and 22% over the month amid high demand for data center power. Caterpillar, which experienced a boom in its data center power-generation equipment business this year, saw its shares fall 32% over a 30-day period.

Summary

The sudden drop in marquee artificial intelligence and hardware stocks highlights how institutional investors move quickly to protect their annual gains. The sell-off reflects portfolio management and profit-taking rather than a sudden failure in the underlying business fundamentals of these major technology companies.
