Friday's session produced a dramatic intraday reversal across broad equities, but SPY barely moved — closing essentially flat at 740.51 despite swinging from a session low of 735.05 to a high of 744.43. Meanwhile QQQ surged over 4% from its open, and IWM is up nearly 5% on the day, with small caps shredding through the prior put wall at 290 and pushing within striking distance of the 295 call wall.
The real story is under the surface: 0DTE call sweeps in SPX (7400 strike, $88M), SPY (740 strike, $80M, vol/OI 20.3x), and QQQ (720 strike, $65M) point to aggressive intraday directional bets, not passive hedges. VIX collapsed 11% to 18.78 while SPY is essentially unchanged — an unusual divergence that signals vol is being crushed elsewhere (QQQ, IWM) even as SPY treads water. This is a split tape running into weekly expiry gravity.
GEX walls are price levels where dealers hedge aggressively. Price tends to gravitate toward Max Pain and stall near walls.
