Hedge funds increase AI stock exposure amid risks

Hedge funds are boosting AI and tech stock investments, especially in semiconductors. Goldman Sachs warns of market concentration risks and offers a less AI-sensitive portfolio. Arm Holdings' stock jumped 46.5% amid strong AI chip demand.

Hedge funds have ramped up investments in technology and AI-related stocks, focusing on semiconductors and software companies. This surge has pushed their exposure to record levels not seen since 2016. North America and emerging Asian markets are leading this buying trend, while Europe lags behind. Goldman Sachs has cautioned that the AI-driven rally is creating a more concentrated trading environment. This increases risks, as market gains are increasingly tied to a single dominant theme. In response, Goldman introduced an 'insensitive portfolio' featuring stocks with positive earnings revisions and lower sensitivity to AI trends. This portfolio includes companies from sectors like pharmaceuticals, social media, gold mining, and food processing. Meanwhile, Arm Holdings' stock soared 46.5% in a week, fueled by a $2 billion AI chip deal, bullish analyst coverage, and strong earnings. While demand for AI infrastructure, especially chips, remains a key driver, risks include potential slowdowns in AI spending or disappointing results from major players such as Nvidia or Microsoft.
