would tell us that option holders would not exercising at .70 just to sell them to make a few pennies. These folk`s used their money to exercise and would not do so unless they thought (knew) that now was the time to act, as most have years before their options expire.
It is my opinion that insider buying (or exercising) in any stock is done because they know something (that is why they are called insiders). We do not know if they are expecting a spike and therein would be sellers or if they know of settlements or dividends or buyouts or whatever. What we do know is that people in the know are putting their $`s into ptsc and to me that is news, positive news.
Of course this is my opinion but to me that matters.
God Bless
