Berkshire Hathaway (NYSE: BRK-A) (NYSE: BRK-B) CEO Warren Buffett doesn’t think his wife should invest in Berkshire stock after he’s gone, which may come as a surprise given Berkshire’s track record and Buffett’s own optimism for the company after he’s gone. Charlie Munger, Buffett’s right-hand man, disagrees. He thinks Berkshire will put his heirs in the best position to grow their inheritance going forward.
