I bought a company in the mid-90s called Dexter Shoe and paid $400 million for it. And it went to zero. And I gave about $400 million worth of Berkshire stock, which is probably now worth $400 billion. But I've made lots of dumb decisions. That's part of the game.
I look for businesses in which I think I can predict what they're going to look like in ten to fifteen years time. Take Wrigley's chewing gum. I don't think the internet is going to change how people chew gum.
We do not have, nor have had, and never will have an opinion about where the stock market, interest rates, or business activity will be a year from now.
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.
I have a house that I bought 55 years ago. It's warm in the winter; it's cool in the summer. It has everything I wanted, plus it has all kinds of good memories. Like my kids, I have good thoughts about that. I can't imagine living any better.
I think once you start putting phony figures into financial statements, you get in a lot of trouble. And we've seen so much of that in the last 20 years.
Ben's Mr. Market allegory may seem out-of-date in today's investment world, in which most professionals and academicians talk of efficient markets, dynamic hedging and betas. Their interest in such matters is understandable, since techniques shrouded in mystery clearly have value to the purveyor of investment advice. After all, what witch doctor has ever achieved fame and fortune by simply advising 'Take two aspirins'?
If some institution wants to sell you a billion dollars worth of mortgages, they might have to sell 100 million in the market, and then you'll buy the other 900 million on the same terms. Now, the very fact that this has been authorized or will be authorized, I hope, will firm up the market to some degree. And that's fine. But you don't want to have artificial prices being paid.
Investors should be skeptical of history-based models. Constructed by a nerdy-sounding priesthood using esoteric terms such as beta, gamma, sigma and the like, these models tend to look impressive. Too often, though, investors forget to examine the assumptions behind the models. Beware of geeks bearing formulas.
