MDVN is HOT as HOT can be!
I think they let the call expiration carry it down to 75 and are now setting up for a runup on Tuesday. I added more @ 75.02. There is no other obvious reason for it to be up AH other than tape painting.
approx. 240,000 shares traded after hours
PS Note that the amalgamated trade posted at the close would tend to suggest that someone was accumulating around 75.11
