Negative gamma dominant 6/8 watchlist names in negative-gamma territory.

Today's read

Heading into the session, broad equities display a compressed volatility regime with SPY, QQQ, and mega-cap tech all printing negative IVR100—a structural signal that realized moves have outpaced implied pricing, leaving derivative markets leaning defensive ahead of tomorrow's CPI print. AMD stands isolated with positive IVR68, suggesting sector-specific demand for upside convexity that contrasts sharply with the put-heavy flow in SPY ($761 strike, $30.3B notional) and the exceptional call concentration in NVDA at the $210 strike ($210.8B), patterns typically observed when participants are hedging broad exposure while positioning selectively in flagship names into a macro event window. The six-day runway to FOMC, combined with overnight CPI sensitivity, has anchored a bifurcated structure where tail protection dominates index positioning while concentrated tech names attract outright directional interest.

What Would Change My Mind

• If CPI prints >0.4% MoM tomorrow and SPY closes below $758 on first test, negative gamma regime cascades into dealer forced selling as portfolio insurance triggers, collapsing the bid into $750 support where gamma inflects positive.
• If NVDA breaks above $227.50 flip level with IVR compression to 72 or below across the six names, dealer short gamma unwinds mechanically and structural short-vol positioning reverses, signaling regime shift to positive gamma dominance before FOMC.
• If QQQ holds $716 through FOMC but implied volatility structure inverts (front-end IV >back-end IV for first time in 8 days), dealer hedging becomes unanchored and gamma neutrality breaks, forcing rebalance into whichever direction fills the vol term structure gap.
