I am seeing 34.62% increase for PQE (Stutgart) on Yahoo for the same volume. Interesting indeed.
It would be a great gesture on the part of the BoD to simply say "hello" from time to time to give shareholders a pulse check.
They should also be loading up on shares since most of their options are underwater. (if they believe in the future of the company)
I understand that IBM used to madate that all managers pruchased and owned company stock to that they had interest in increasing the value of the company. Sadly that attitude was never widely adopted.
Today's managers are for the most part given shares at reduced price and sell what ever is vested and above water at every opportunity or so it seems.
