Yes, that is good information. Most are listed by Nasdaq as automatic, indirect and are reasonably regular. < http://www.nasdaq.com/symbol/rkus/insider-trades > As you note if you look carefully at the form you see the RULE 10B5-1. I suspect most sophisticated and institutional investors note this, but the more casual see "SELL":
Tweets, blogs and comments are "insider sells", etc. creating negative optics. Seems to me that the pps always goes down following these reports. Also seems only temporary, but sure can halt a good trend.
I see the rationale for such requirements and suppose Kish wishes he could have sold more months ago. I wonder if they can temporarily override a sale? For example Lo hasn't sold for a while.
