There 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 Buffett... but the important thing is that when you do find one where you really do know what you are doing, you must buy in quantity.... Charlie and I have made a dozen or so very big decisions relative to net worth, although not as big as they should have been.

Warren Buffett[Gold] gets dug out of the ground in Africa, or someplace. Then we melt it down, dig another hole, bury it again and pay people to stand around guarding it. It has no utility. Anyone watching from Mars would be scratching their head.

Warren BuffettWhen somebody makes it very easy for you to do it by saying you don't really have to put up my money, you can lie about your income a little, or we'll give you 100 percent mortgage, you're going to do it, because everybody that's done it has been proven right. You have social tools, and you're going to feel like an idiot if you didn't do it, because the house cost more.
