Ok, Im new to trading, and stock market in general. Can someone explain in beginner's language how I exercise stock options? Here is my scenario: Upon being hired I was granted 2,500 shares of ACUS, which was trading at $1.75 per share. CURRENTLY IT IS TRADING AT $0.43 per share! I am leaving the company and thus have 90 days to exercise my options. Am I going to lose these shares if ACUS price doesnt go back up to $1.75? Is there anyway to avoid this or is it just inevitable because the company stock price has fallen so much? Any help would be greatly appreciated yes they are vested options I was given, not bought... raysor. So as I figured, they are worthless and useless since the stock price isn't going up $1.35ish anytime in the next 90 days.
