SPY (734.66) opens surrounded by negative gamma, with almost nothing positive overhead. The strikes on either side of price are the heavy ones: 730 holds −$218M, 4.66 under spot, and 735 holds −$190M, 0.34 above it, with 725 (−$251M) the largest on the board and 740 (−$125M) the next one up. Across the whole chain only +$11M sits above spot, against −$1,597M below it, so the net is −$1,586M.
Thursday's map is gone. Thursday's open showed a +$256M chain with a 774.72 flip, a 770 call wall and a 764 put wall, with SPY at 767.40. Today the chain is −$1,586M, the feed returns no flip, the call wall is 755 and the put wall is 725, and spot is 32.74 lower. Implied vol (ATM) is 40, up from 16, and the expected move is ±1.5% (±$10.90, or 723.76–745.56), against ±0.6% on Thursday.
The positive strikes are out of reach. 51 of the chain's 137 strikes are negative, summing to −$2,065M, and the 77 positive ones add up to +$479M: 751 through 760 nets +$221M, with the 755 call wall (+$54M) 20.34 over spot and outside the top of the expected move (745.56). Max pain is 745, 10.34 above. The feed carries only the 0DTE chain (one expiry, 250 contracts), so open interest further out is not in these numbers.
Net gamma by strike near spot: 719 −$122M, 720 −$160M, 721 −$47M, 722 −$43M, 723 −$50M, 724 −$47M, 725 −$251M, 726 −$43M, 727 −$59M, 728 −$77M, 729 −$59M, 730 −$218M, 731 −$75M, 732 −$61M, 733 −$51M, 734 −$35M, 735 −$190M, 736 +$31M, 737 +$19M, 738 −$43M, 739 +$3M, 740 −$125M, 741 −$39M, 742 −$11M, 743 +$1M, 744 −$12M, 745 +$23M, 746 +$2M, 747 +$10M, 748 +$11M, 749 −$17M, 750 −$27M, 751 −$4M, 752 +$19M, 753 +$25M, 754 +$30M, 755 +$54M, 756 +$18M, 757 +$16M, 758 +$9M, 759 +$12M, 760 +$43M. The chain has 51 negative strikes in all, summing to −$2,065M, against a −$1,586M total.
