SPX opens negative gamma, hedges are intact, and Tuesday's CPI lands with December hike odds at 80%. TL;DR 1/ SPX opens in negative gamma, so dealer hedging will mechanically amplify moves in both directions regardless of direction; treat sharp intraday swings as noise until positioning shifts. 2/ Tuesday's CPI is the week's fulcrum: with December hike odds near 80% and the Nasdaq 100 still deep below its 200-DMA, an upside surprise could destabilize the nascent bounce. 3/ The Jensen Huang affair is a material key-man risk event for Nvidia, but the more important structural story this week is vol mechanics and CPI, not the idiosyncratic headline. 4/ Iran risk has repriced on Trump's conciliatory weekend commentary, but Qeshm Island strikes continued overnight and the diplomatic path is binary; don't treat the energy bid as durable. 5/ A convex squeeze higher is a live risk as CTAs and leveraged ETFs would be forced buyers into any rally, but put/call skew across tenors signals existing hedges are firmly in place. Regime: Fragile. Lean cautiously defensive into Tuesday's CPI.
