AMD fell nearly 7% Tuesday after reports surfaced that Chinese AI developer DeepSeek is building its own proprietary chip for AI inference — a direct challenge to the thesis that’s underwritten the entire AI hardware trade: that a small handful of Western vendors own the silicon layer outright. The selloff didn’t stay contained to chips. It fanned out into every high-multiple, story-driven sector on the board.

Quantum computing, commercial space, and eVTOL/drone names — all trading more on narrative than earnings — took the worst of it. Rocket Lab dropped over 10%, and the drone complex fell 8-9% across the board. NVDA, notably, barely moved, up 0.7%, which suggests the market is drawing a line between chipmakers it sees as structurally defensible and those it doesn’t.

Meanwhile, the tape found somewhere to put money to work: oil and gas. Every major name in the group closed up 3-6%, led by Occidental. Gold and copper miners did not catch a safety bid — they were sold too — which tells you this was a rotation out of story stocks into cash-flowing hard assets, not a classic flight to safety.

RKLB $74.21 (-10.4%) — Rocket Lab took the hardest hit in our sector universe, compounding broad AI-adjacent de-risking with its own reported $8B move to acquire Iridium Communications — a bold vertical-integration bet that raises near-term integration and leverage questions even for bulls.

AMD $516.11 (-6.5%) — The proximate cause of Tuesday’s rout: reports that DeepSeek is developing a proprietary AI inference chip, a direct challenge to the AMD/Nvidia hardware moat narrative.

Energy complex (+2.8% to +5.9%) — Occidental, Exxon, and Chevron all rallied hard as capital rotated out of speculative growth and into cash-generative energy names.
