Greetings! I've got a question regarding the most basic of questions: insider sellout. The company in question came under my review as a possible long-term shorting candidate due to being in a weak industry, as well as (in my newbie opinion) heightened earnings expectations; despite that, the company seemed to have strong fundamentals (and, indeed, has been trending up for some time now). However, what caught my eye when reviewing it was the huge insider selloff rate with no buy - over 2 mil shares, or 90%, were liquidated within the last six month; out of them, almost 1.3 mil happened within the last month. My question is, should this be considered a definite "nail in the coffin" that ought to seal my decision to short, or may a rapid and massive non-takeover selloff be caused by some other factor? Thank you.
