Negative net GEX across SPY (-3.17B), QQQ, and especially IWM (-4.44B) means dealers are short gamma, so...
👉 expect amplified, trend-following moves rather than pinning!!!
$SPY ’s $760 put wall is the key line—hold it and the $761–$772 expected range stays intact toward the distant $785 call wall; lose it and downside accelerates.
$QQQ trades between its $730 put and $745 call walls while
$IWM sits right on the $280 put wall, making small-caps the highest-vol name if that level breaks.
