Market Overview
SPY +1.09% to $762.30, QQQ +1.65% to $716.37, IWM +0.92% to $286.52. The indices are moving closely enough together that follow-through matters more than sector rotation. VIX down -11.79% to $15.62 gives continuation more room if buyers stay in control.
Standard Deviation Analysis
SPY is -0.44 standard deviations from the 20-day mean, with spot at $762.30 versus a mean of $764.33. That puts 1SD at $768.96 on the upside and $759.70 on the downside, with 2SD at $773.59 and $755.07. That is close enough to the mean that direction matters more than the raw SD read. Let price prove the next leg. A softer VIX at $15.62 keeps continuation alive if price can hold above key pivots.
Market Sentiment
The sentiment read is coming from price structure, volatility, and crowding rather than a separate sentiment index. With SPY near the mean, sentiment matters less than which side wins the next push. VIX easing -11.79% gives the tape more room to continue if leadership holds. Retail attention is concentrated in $SPY, $SPCX, $BUMS, which matters most if those names start failing while SPY is stretched.
Scenario Map (Educational)
