Challengers paid, champions sold — Seoul enters a bull market as the rotation shows its hand

Daily Pulse — No Bursting Bubble — The Rotation Inside the AI Trade, in Four Panels, With PPI as the Hinge

The rotation inside the AI trade is real, and it is not a bursting bubble: capital has moved from AI capex to AI opex and AI applications, and our index family tracks it in four lines. The Rubin build-out basket has gone sideways for months and still sits above +100% for the year; the Agentic Ecosystem index closed at its high, up more than 60%; Agentic Winners has climbed to its best level since January; HALO — growth unrelated to AI — is firming. Meanwhile the 2026 capex forecasts have moved from below $300 billion to more than $700 billion guided. Overnight, the tape said the same thing in single names. PPI at 14:30 CET is the hinge on all of it.
