TRXC is up 16% over past month. TRXC was originally up more than 10% on ALF-X acquisition, but when you factor in broad healthcare sell off and dilution associated with deal, you're bound to get a brief pull back.
Remember way back from your finance 101 class, this shouldn't be too hard: When an acquisition is announced, the acquirer drops (on concerns of synergies, integration), and the acquiree pops.
When you put all of these factors together, I wouldn't expect such obtuse, short-term questions from you. But clearly I'm wrong!
