This is kind of scary the Pfizer CEO would dump that much stock. Maybe he knows the lab results for the early enrollees and there antibodies are diminishing sooner than we would expect.

That this announcement was too soon. Might of been 90% effective but for how long? Only 3 months? Only 6 months? I would think that the CEO knows this lab information and is grabbing a positive stock price jump while it lasts before the big drop when everyone knows what he does. Like everyone... we wait to see time sensitivity of antibodies.
