Chinese quantitative hedge funds took a heavy hit last week as a global selloff in semiconductor stocks triggered sharp losses in their portfolios. High-Flyer, one of the country's largest quant firms, saw its flagship fund drop 15.7% in a single week.
How the chip rout hit quant funds
The selloff, which swept through chipmakers worldwide, landed hardest on funds that had loaded up on artificial-intelligence-related stocks. Chinese quant firms, known for using algorithms to spot and ride market trends, had been piling into the same AI names. When the global chip rout began, those crowded positions amplified the damage.
High-Flyer's 15.7% weekly loss is among the steepest reported by a major Chinese quant fund in recent months. The firm manages tens of billions of yuan and is a bellwether for the sector. Other quant funds also suffered, though exact figures have not been disclosed.
Crowded AI trades exposed
The losses have laid bare a problem that had been building beneath the surface: too many quant funds chasing the same AI trades. For months, Chinese quant firms had been piling into semiconductor and AI stocks, betting on a sustained rally. The chip selloff turned that bet sour, and the simultaneous exit by multiple funds worsened the slide.
Industry observers say the episode highlights the risks of herding behavior in quantitative strategies. When many funds use similar models and trade the same names, a sudden reversal can trigger a cascade of losses. The chip selloff was the trigger, but the underlying vulnerability was the crowded trade itself.
High-Flyer has not commented on the loss. The fund's performance is closely watched by investors and rivals alike, and the 15.7% drop is likely to prompt a reassessment of risk controls across the sector.
The question now is whether the chip selloff will deepen, forcing more quant funds to unwind their AI positions. If it does, the losses could spread further. For now, the industry is watching the semiconductor market — and its own crowded bets — with a new wariness.
