You are grossly predicting the reason he is selling. Are you a soothsayer? There are plenty of other reasons to sell that have zero to do with Apple's business prospects or his own at Apple. It could be fear of a cap gain increase in 2012, or the need to get into cash for personal reasons, or a desire to diversify his portfolio or a million other things. This sale tells us only one thing for sure: that he sold a lot of stock.
I remember years ago Bill Gates selling lots of Microsoft shares, and some people here predicting doom for Microsoft. And I'll say the same thing as I said back then, just names changed: If Bob Mansfield goes to a store selling Ferraris, and he wants a Ferrari, all the AAPL stock in the world won't get him the car he wants. He has to sell the shares, convert them into cash, hand over the cash to the car dealer, and only then will they let him have the car he wants.
What good is it to him having all the shares if he doesn't sell and spend the money?
