SPY Weekly Options Positioning Map: 710 Wall, 700 Floor, 675 Deeper Support
SPY is sitting directly on the 710 gamma wall after a +4.8% week. Aggregate gamma is now strongly positive, monthly positioning flipped from negative to positive, and the near-term range tightened to 700-710. Spot is 3.2% above max pain (688), the widest dislocation in weeks. Watch the 706 GEX flip below spot.

Grading last week's chain map. The 685 pivot was taken out Tuesday. The 700 ceiling was gone by Thursday. The 660 floor was never threatened. Neutral bias missed a +4.8% rally, the third straight week the vanna mechanism was called correctly but underweighted in the headline.
