I understand that for a new company or a private company, but Google's stock is hardly comparable. I'm just curious how much it'd cost to lock in the value of his shares and then borrow against it.
Even if google itself isn't going anywhere, if the stock market falls over again it could cut a big chunk out of the value of everything, including "safe" companies like google.
And of course I'm sure that's not hard to account for with some simple financial instruments.
