If you do smart things and use leverage and do one wrong thing along the way, it could wipe you out, because anything times zero is zero. But it's reinforcing when the people around you are doing it successfully, you're doing it successfully, and it's a lot like Cinderella at the ball.
Warren BuffettThe managers at fault periodically report on the lesson they have learned from the latest disappointment. They then usually seek out future lessons.
Warren BuffettThere is one thing of which I can assure you. If good performance of the fund is even a minor objective, any portfolio encompassing one hundred stocks (whether the manager is handling one thousand dollars or one billion dollars) is not being operated logically. The addition of the one hundredth stock simply can't reduce the potential variance in portfolio performance sufficiently to compensate for the negative effect its inclusion has on the overall portfolio expectation.
Warren BuffettThat's been lost. It's a huge problem. What you have is you have the major institutions of the world all wanting to deleverage. They want to take down their assets and liabilities. What seemed so easy to borrow against a year ago now looks like rat poison to them. So they're trying to deleverage. There is only one institution in the world that can leverage up in a way that's all a countervailing force to that, and that's the United States Treasury.
