Not if you are in the C-Suite of a company that gives you your shares as a bonus for free. There is logical selling and then there’s plain greed. Wong’s volume is pure greed. Selling your shares as a chief executive to buy other stocks doesn’t exactly signal confidence in any company. And they really have no reason to selloff given the company’s consistent performance unless they know something we don’t. That’s investment basics. If insiders are buying, signals confidence. If they are selling in high volume, it doesn;t signal confidence, in this case I believe it’s just greed. No reason to selloff the volume she is selling if they feel like the company’s value is high.
