@algotradedesk Yesterday the S&amp;P500 rose +1.59% but $VIX climbed also. Is it typically bearish when VIX rises when $SPX does too? Historically, no statistically significant next day effect. Yesterday was 891st time since 1990. Next day, $SPX lower 52% of time by ~64bps. Up 48% of time by ~58bps
