SPY Holds Long Gamma Above 766.95 as Tech Drag Pressures Indices

The broad market pulled back late Wednesday afternoon as tech stocks faced selling pressure, but dealer positioning across the major index trackers tells two distinctly different structural stories. MT Newswires reported that technology equities sank heading into the close alongside rising Treasury yields, alongside warnings from the IMF regarding equity risks tied to debt-financed AI capital expenditure. While headline writers framed the session around the late-day software and chip selloff, the derivative structure underlying SPY and QQQ prevented the slide from broadening into a directional break. SPY trades at 767.99, holding just above its gamma flip at 766.95. Positioned in long gamma territory, dealers act as counter-trend liquidity providers—buying weakness into the 767 put wall and selling into upside pushes toward the 771 call wall. The expected move for the session sits tight at ±0.77%, with skew at 1.1. So long as spot remains above 766.95, dealer hedging flows act as a dampener on overall volatility, absorbing intraday sell orders rather than amplifying them. QQQ reflects a similar stabilizing backdrop despite tech bearing the brunt of the headline noise. Spot closed at 741.81, comfortably above its gamma flip at 738.08. With its put wall parked at 740 and call wall at 750, the tech index carries an expected move of ±1.1% and a elevated skew reading of 3.7. The structure shows dealers remain long gamma here as well, insulating the index above 738.08 and keeping price contained within established boundaries. IWM presents the opposing structural picture. Small caps closed at 281.99, sitting firmly below the 286.05 gamma flip in a short gamma regime. In short gamma, dealer hedging works against stability—dealers are required to sell into declines and buy into rallies, adding momentum to price swings. With its put wall down at 280 and call wall at 290, IWM retains a wider expected move of ±1.21% and skew of 1.8. The structural line of control sits at 286.05, keeping intraday moves in small caps volatile compared to the insulated large-cap tape. I track structural positioning to map where dealer hedging creates friction or acceleration. What you execute around these boundaries is entirely your own click.
