The tape carries in risk-on — 41 of the 50 names our screener ranks hold a BUY bias, with 62% advancing. But it is not buying everything. Overnight, capital paid up for earnings you can underwrite — semis, AI-infrastructure, the mega-caps — and offered the story-multiples: OKTA, CRWD, DDOG, alongside an MRNA air-pocket.
That is the board you are trading into. And the single thing that decides today is not the index — it is whether the AI-infrastructure bid holds its nerve. Leadership is concentrated in the exact same names, and they share one tail. When the crowd is standing in one place, the floor beneath it is only as wide as the last catalyst.
