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

Today's read

Equities are pricing in a risk-off posture heading into the FOMC decision in two days, with all major indices trading in negative regime and large notional put flows concentrated in QQQ and SPY at near-the-money strikes—a structural pattern that typically emerges when systematic hedging or portfolio insurance accelerates ahead of high-conviction macro events. The $880M put volume in QQQ at $705 strike (essentially at-the-money) relative to SPY's $726 puts suggests investors are calibrating downside hedges more aggressively in the tech-heavy index, consistent with rate-decision uncertainty compressing risk appetites. The dominant narrative through the session will likely remain anchored to Fed messaging expectations, with any volatility expansion or contraction in equity derivatives closely tracking real-time repricing of rate-path odds.

What Would Change My Mind

• If SPY breaks below $758 and closes there for two consecutive sessions → negative gamma trap inverts to positive, dealers shift from forced sellers to buyers, mechanical support structure reverses.
• If QQQ reclaims $712 with volume spike above 60M shares and holds through FOMC without pullback → gamma dynamic weakens, dealer hedging becomes discretionary rather than mechanical, thesis loses structural tailwind.
• If NVDA fails to approach $250 flip zone and instead consolidates $205-$215 for 3+ days ahead of FOMC → conviction in convexity suppression signals dealer positioning may have already shifted, negative gamma dominance becomes transitory rather than structural regime.
