If any large pools want to instigate a firesale, usually it starts overseas. If overseas markets are crashing then it's puts the structure of US economy at risk. It would be laughable and transparent if overseas markets didn't correlate with domestic markets. It would pinpoint the invisible hand that manipulates domestic markets.
High today barely breached 11/27 high and closed below it which tells me strong resistance however it is bullish outside vertical bar but again barely.
