Berkshire eating the cost of Buffett's advice to Obama
The stock repurchase seems to me a tactic to have some investors sell the stock now so they can keep their capitals gains before Obama raises the capital sales tax.
So Buffett buys the shares so that the stock price won't get hit by huge sales.
In the process the capital of Berkshire gets reduced.
Funny.... Looks like Buffett can't even keep his investors in believing on his tax message.
