Technology Sector ETF Shorts Triple to Over 18M Shares; Littelfuse Stake Cut $5.19M
Short interest in the Technology Select Sector ETF climbed from 6.5 million to over 18 million shares between November and late January, reflecting concentrated hedges against Nvidia, Apple and Microsoft leadership. Meanwhile, Segall Bryant & Hamill cut its Littelfuse stake by 20,392 shares (~$5.19M) and CoreWeave navigates three structural risks.
1. Technology ETF Short Interest Surge
Short interest in the Technology Select Sector ETF surged from approximately 6.5 million shares in November to over 18 million by late January as hedge funds targeted concentrated exposure to Nvidia, Apple and Microsoft, signaling strategic hedging against AI-driven mega-cap leadership rather than broad tech bearishness.
2. Segall Bryant Reduces Littelfuse Stake
Segall Bryant & Hamill reduced its position in Littelfuse by 20,392 shares—equivalent to about $5.19 million—in Q4 2025, despite a 47% share price rally over the past year fueled by AI demand for circuit protection and power management solutions.
3. CoreWeave Faces Structural Risks
CoreWeave, a key AI infrastructure provider, confronts three main structural risks: competition from hyperscalers like Azure and AWS reducing differentiation, persistent high capital intensity limiting returns, and the potential for major customers such as OpenAI and Meta to insource compute as supply constraints ease.
