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

Today's read

The tape is split along classic tech-versus-everything patterns: mega-cap growth (AAPL, MSFT) is elevated on implied volatility while the broader complex (SPY, QQQ, NVDA, AMD) shows depressed IV rank heading into tomorrow's FOMC decision, suggesting market participants have already priced baseline expectations into the largest names. Equity flow is notably concentrated in call structures at round strikes—IWM $250 calls and SPY $660 calls represent substantial notional commitment—which typically reflects either hedge-roll activity or positioning ahead of the policy announcement. With monthly OPEX three days out and the Fed decision imminent, this regime often exhibits regime-dependent volatility compression followed by post-catalyst repricing, making the overnight session a natural inflection point for term-structure reassessment.

What Would Change My Mind

• If SPY sustains a close above $765 post-FOMC with VIX compression below 14, negative gamma positioning unwinds into dealer long covering rather than forced selling, reversing the asymmetric downside amplification structure.
• If QQQ breaks decisively below $700 on FOMC guidance and fails to recapture that level within two hours, the mechanical hedging cascade from dealer short gamma becomes self-reinforcing, with $685 representing the next structural inflection where rebalancing demand could accelerate.
• If NVDA closes between $215-$218 through OPEX expiration (3 days) while implied volatility stays elevated above 45%, short call gamma pinning breaks down and the $213-$235 range widens into a genuine two-way flow regime, eliminating the asymmetric dealer-flow amplification thesis.
