Good questions. Not sure of anything, but I think the buyback is a secondary goal. The primary goal is to increase the pps so that that top management can cash out on the strongest possible terms and go on their merry way.
As to today's and yesterday's strong bid, I wonder if they are already the at the JPM conference holding private conversations and giving inside "color" to those priviledged to be there?
