🐢 **Dataroma: Burry Shorts Caterpillar After Its AI-Rally Double**
Michael Burry opened his first-ever short against Caterpillar after the stock nearly doubled in 2026's AI-driven rally, a contrarian bet that cuts against BlackRock, PIMCO, and Schroders' broadly constructive H2 2026 equity outlooks, each of which nonetheless flags AI-theme concentration and stretched valuations as a key risk. Nearly all of the Nasdaq-100's H1 2026 gains have come from just ten stocks, underscoring the narrow breadth Burry's position appears to be betting against.
