Short sellers are significantly increasing bearish bets on European companies vulnerable to artificial intelligence disruption, according to data cited by Bloomberg. The short interest ratio for a basket of AI-exposed stocks compiled by UBS has jumped by over 5% on average, up from just 2% two years ago, signaling growing pessimism about these companies' prospects.

Companies with short interest ratios above 5% include major European names like Ubisoft Entertainment, though specific company names were redacted in the source. The UBS basket itself has slumped 39% over the past year, dramatically underperforming the pan-European Stoxx 600 index. This decline reflects broader market concerns about AI's potential to disrupt traditional business models across sectors.

Analysts note that tech investors are navigating an "extremely unsettled landscape" with unprecedented uncertainty. The software and services sector has become particularly volatile, with stocks experiencing wild swings based on minor earnings beats or misses. Even announcements from obscure startups can trigger sector-wide selloffs, highlighting how AI fears are reshaping investment strategies across European markets.
