Just wondering what others thoughts are about premiums built into a stock price depending who the CEO is.    How do you even go about trying to figure that out?   I guess what got me thinking about this are rumors/speculation that Steve Jobs may have health issues.  Obviously, some Wall Street are spooked about this.  If Steve Jobs could no longer run the company tomorrow,  the stock would obviously take a hit.  How much though is anyones guess.    Look at Berkshire,  is it fair to say  20%-30% or more of the stock price is a Warren Buffet premium ( meaning if Warren Buffet was no longer with the company tomorrow, the stock would drop that much immediately).   I certainly don't know the answer.
