the short term shareprice move will not have hurt shareholders if the shareholders have not sold. If IDCC sells for north of $82.50 per share then shareholders who have held will have not have been harmed by the short term movement.
In any case, the only reason that the shareprice spiked to the 70s and low 80s is because IDCC stated they are seeking strategic alternatives. Perhaps if IDCC never made the statement, we would be in the 40s anyway, and we wouldn't know the difference.
I also believe that if IDCC kept us informed weekly on price and status of bids, and then a deal falls through, I am sure shareholders will be as equally unhappy. Let's hope we all get a win.
Remember there are plenty of IDCC employees and management and the BOD that are shareholders also. So, let's count on them looking out for not only the shareholders, but themselves and each other.
