Thursday's session opened with a bearish tilt and promptly scrambled it — QQQ surged as high as 711.26 and IWM tagged 289.00, both crushing their morning resistance levels, while SPY spent the day grinding in a tight band pinned near its 730 max pain level. The divergence is sharp and data-supported: SPY net GEX sits at -$10.86B with 74.6% of 0DTE volume concentrated within 0.27% of max pain, while $134M in competing SPX 0DTE sweeps — split nearly evenly between a $69M bullish call and $121M in bearish puts — signal genuine two-sided uncertainty at the index level.
GEX walls are price levels where dealers hedge aggressively. Price tends to gravitate toward Max Pain and stall near walls.
