While the timing of Frazier's sales are somewhat suspect they don't seem to be out of line with his previous transactions.
This transaction was a equal option exercise and sale so he only netted in the $9mil range less taxes. This was all under a Rule 10b5-1 trading plan, so we don't really know what triggered the transaction.
Not much to think about considering he didn't dilute his holdings.
