Very interesting day. Price was forced down but someone was out there buying the April calls that were being dumped. There was a large buyer in May calls as well. Not so much action in the puts. I will leave the analysis to the option gurus. Absent some kind of leak my guess is you had folks locking in their gains by selling shares and keeping their upside by buying options that were being dumped. Then Baird after the close.....wild ride.
