I don't know, this is a business that spits out a copious amount of cash every quarter to reinvest. I own other stocks that I worry daily about how their cash is being allocated. When it comes to Berkshire I just don't even bother worrying. That's not to say I'm not interested, of course I am, but what is the purpose of worrying about how all this is being reinvested when we've already created such an incredible profit stream? Mistakes will be made-- as in any business-- but far be it me to try and poke holes in what Warren, Charlie and the gang do. And to be fair I appreciate the comments to the contrary, they offer a valuable perspective that permeates our beloved Berkshire bubble but it just doesn't worry me what they are going to do with our money.
