The stupid and dishonest accountants allowed the genie of totally inappropriate accounting to descend on derivatives books. And once this has happened - people get status, etc. - it's impossible to get it back into the bottle.
Charlie MungerWe believe that almost all really good investment records will involve relatively little diversification. The basic idea that it was hard to find good investments and that you wanted to be in good investments, and therefore, you'd just find a few of them that you knew a lot about and concentrate on those seemed to me such an obviously good idea. And indeed, it's proven to be an obviously good idea. Yet 98% of the investing world doesn't follow it. That's been good for us.
