Just got a question if anyone could enlighten me. There are periods where directors and such of the company can buy shares on the market and periods where they cant. And if I remember correctly or maybe I'm mistaken, they cannot buy right before major announcements. I'm just wondering if this doesnt apply for options or is this a period where they are allowed to buy? Pheww hope I didnt go round in circles there with my question.
