Anyway, all insiders have a lot of shares to sell. Exercising stock option usually is part of their compensation program. So, if you were one of the insiders, when would be the best timing for you to sell your shares?
My suggested theory: When there is insider selling, the insider will hate to see the stock price going lower. So, he usually will choose a period with steady supply of positive news to sell his shares. Translation:
Insider selling usually is indicative of positive business outlook or development going forward.
Supporting evidence to my theory: Today, XLNX reiterates its forward guidance.
