Heading into this afternoon's blow off top, which saw the S&P close at the highest level since April 2022 after 6 straight days of gains (the longest winning streak since Nov 2021), the post-FOMC gamma squeeze (because apparently nobody believes or is scared of Powell any more) was in full blast, not just across the vanilla Greek space but especially 0DTE, with the most traded option of the day being the SPY 440 (S&P4,400) Call expiring today, and for good reason: opening at 14 cents, it was up 3,050% to $3.15 when we snapshotted it just before the close...
