The model I like to sort of simplify the notion of what goes on in a market for common stocks is the pari-mutuel system at the racetrack. If you stop to think about it, a pari-mutuel system is a market. Everybody goes there and bets and the odds change based on what's bet. That's what happens in the stock market.

Like the stocks of both Berkshire and Wesco to trade within hailing distance of what we think of as intrinsic value. When it runs up, we try to talk it down. That's not at all common in Corporate America, but that's the way we act.

[GEICO] got to thinking that, because they were making a lot of money, they knew everything. And they suffered huge losses. All they had to do was to cut out all the folly and go back to the perfectly wonderful business that was lying there.

We bought a doomed textile mill [Berkshire Hathaway] and a California S&L [Savings & Loan; Wesco] just before a calamity. Both were bought at a discount to liquidation value.

It's a finite and very competitive world. All large aggregations of capital eventually find it hell on earth to grow and thus find a lower rate of return.

It takes character to sit there with all that cash and do nothing. I didn't get to where I am by going after mediocre opportunities.

It's dishonourable to stay stupider than you need to be
