max pain was 472 yesterday. so op-ex play would have been close around 472 depending on the options opened yesterday.
imo, yesterday's afternoon rally was concerted fund manip that outweighed the profits deep pockets would have gained from flushing open options at max pain.
they used bots to buy en masse to run it up to profit from the calls as well as being able to distribute that shares they bought on the way up at higher prices today and maybe into next week?
far too many possible scenarios to speculate with confidence. the only thing that seems clear to me is that yesterday's afternoon rally was not a organic market behavior.
