Time Cook owns about 800k shares of AAPL. Of course he is technically employed as a top level manager, but it's naive to think CEOs and other senior executives don't make decisions in their own interests as well as those of their nominal employers (many of whom never even vote on company business).

I'm not singling Cook out here, he seems like a nice person. But i think you understand that there's a big difference between being a regular worker bee and CEO of a large corporation.
