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

Today's read

Broad equities heading into the session with depressed implied volatility across the mega-cap complex—SPY, QQQ, and AAPL all showing IVR100 in negative territory—while pockets of elevated IV persist in semiconductors, where NVDA and MSFT display positive skew regimes that typically reflect elevated tail hedging demand. The flow summary reveals meaningful put accumulation at NVDA's $230 strike alongside substantial call positioning in AMD at $540, a structural divergence that suggests market participants are pricing asymmetric risk profiles within the chip sector despite broad IV compression. The NFP jobs report arriving in two days represents the dominant macro catalyst, and historical precedent indicates that data events of this magnitude often precede IV regime shifts, particularly if printed surprise flows accumulate ahead of the release.

What Would Change My Mind

• If SPY closes above $770 on NFP day with implied vol contracting below 60th percentile → dealer short vega unwind forces synthetic long repositioning, flipping the negative gamma regime into positive gamma dominance across the tape.
• If NVDA breaks above $230 flip while QQQ remains below $739 → stock-specific gamma becomes decoupled from index structure, suggesting institutional accumulation independent of macro positioning and invalidating the broad negative gamma thesis.
• If AAPL fails to recapture $340 resistance after NFP and closes below $325 → dealer gamma hedging accelerates downside momentum as synthetic short positions cascade, extending the negative gamma regime beyond the two-day macro event window into structural weakness.
