$ROKU Call sellers want it below 157.5 so they can take all the marbles and they didn't push tis up pre mkt and sell all this call volume without knowing where they can move price to. I mean who would short that many options today expiring in 2 days without knowing? Whales and institutions that work over retail every week. Look at the open interest and todays volume and the option price that they collected at the contract hi today b efore pushing the stock price down. Any doubt?
