"tomorrow is promised to no one."Why you say that? sorry if it's a question too stupid for you, but I cannot understand why any owner will sell half or more of his company to the market if he know the company will profit much better in the future.
Actually is easier to see my problem:
If you have shares on Microsoft and you think the company will profit better in the future, you won't sell them, you keep them.
Why Bill Gates sold them then?
bottom line answer is diversification of their assets.
