September's opening act delivered on its bearish billing — SPY gapped down, QQQ touched 705 before bouncing, and a cluster of 0DTE put sweeps totaling over $386 million hit SPX within the first minute of trading. Three hours into the session, however, the tape has stalled: SPY is sitting just above its put wall at 760, VIX has faded from its open high of 15.86 to 15.80, and 74% of SPY's 0DTE volume is concentrated near max pain at 761 — the structural equivalent of a rubber band pulling price toward the center.
The question for the afternoon isn't whether bears were right this morning — they were — but whether the negative gamma environment that invited this selloff will now amplify a second leg lower, or whether the 0DTE pin at 761 acts as a gravitational floor into the close. With IWM pressing its put wall at 290 and AAPL surging over 3% as an outlier, today's tape is fractured and positioning-heavy. The next two hours will tell the story.
GEX walls are price levels where dealers hedge aggressively. Price tends to gravitate toward Max Pain and stall near walls.
