Negative gamma dominant 5/8 watchlist names in negative-gamma territory.

Today's read

Heading into today's session, the broad market structure reflects a bifurcated regime—large-cap tech (SPY, QQQ, NVDA, AMD) is trading in depressed implied volatility while defensive mega-caps (AAPL, MSFT) show elevated IV, suggesting positioning ahead of the FOMC decision later today. The notable structural detail is concentrated put flow in mega-cap names like TSLA and META, which typically precedes intraday vol expansion around rate-sensitive announcements. With monthly OPEX settling in two days and a binary macro catalyst arriving today, the next 24 hours will likely determine whether current IV regimes persist or reprrice materially post-decision.

What Would Change My Mind

• If FOMC delivers a dovish hold and SPY sustains above $762 through close with QQQ reclaiming $710, dealer short-gamma unwind accelerates into monthly OPEX, inverting the current pain structure into forced long positioning.
• If NVDA breaks below the $214 gamma flip and holds there through settlement with AMD following lower, the five-ticker negative-gamma cohort transitions from dealer hedging pressure into genuine liquidation cascade, removing the anchor that contained tape-wide volatility.
• If AAPL fails to hold the $330 positive-gamma flip on an intraday FOMC dip and closes below it alongside MSFT deteriorating, the loss of both gamma-long anchors creates a structural vacuum where dealer rebalancing becomes the only marginal bid, collapsing the buffer against broader short-gamma mechanics.
