AI Worries Trigger Sharp Losses for Stock-Picking Hedge Funds
TREE NEWS reports: Concerns over artificial intelligence investments sparked a massive selloff in technology stocks in October, inflicting double-digit losses on several top stock-picking hedge funds and erasing much of their year-to-date gains. Lone Pine Capital, led by Steve Mandel, lost about 9% last month, reversing a 44% gain for the year and leaving the fund down roughly 7% in 2026. Tiger Global Management’s hedge fund fell 8.5% in October, nearly wiping out its annual advance, while Whale Rock Asset Management’s flagship fund dropped about 8%, trimming its 2026 gain to around 34%.
The pain extended across strategies, with chipmakers hit particularly hard. The Democratic sweep in the U.S. midterm elections, which effectively became a referendum on new data center construction, added to the selling pressure. The tech-heavy Nasdaq Composite plunged 5.5% on Thursday—its biggest one-day drop since April 2025—signaling that the market rout may not be over.
Market Impact: Tech, Bonds, Crypto, and More
The AI-driven selloff is rippling through multiple asset classes. In equities, high-flying technology and semiconductor stocks are most vulnerable, as investors question the sustainability of AI capital expenditures. A prolonged downturn could weigh on the broader S&P 500, given the sector’s outsized weight. Bonds may see safe-haven demand if equity volatility persists, but the Federal Reserve’s policy path remains the dominant driver. Cryptocurrencies, which have increasingly traded in tandem with tech stocks, could face further pressure if risk appetite continues to deteriorate. Commodities, particularly those tied to data center construction such as copper, may also feel the pinch. Currency markets could experience volatility as investors reassess growth prospects.
Why This Matters for Investors
The October losses underscore the concentration risk in portfolios heavily exposed to AI-themed stocks. Hedge funds that rode the AI wave to spectacular gains are now giving back returns, highlighting the importance of diversification and risk management. The midterm election outcome adds a layer of political uncertainty, as policies affecting data center construction and AI regulation could shift. Investors should monitor whether the selloff represents a healthy correction or the start of a deeper downturn. With valuations still elevated in many tech names, further volatility is likely. Staying disciplined and avoiding panic selling while reassessing exposure to AI-related themes will be crucial in the coming months.
