No formula in finance tells you that the moat is 28 feet wide and 16 feet deep. That's what drives the academics crazy. They can compute standard deviations and betas, but they can't understand moats.

The fact that people will be full of greed, fear, or folly is predictable. The sequence is not predictable.

I have no views as to where it will be, but the one thing I can tell you is it won't do anything between now and then except look at you. Whereas, you know, Coca-Cola (KO) will be making money, and I think Wells Fargo (WFC) will be making a lot of money and there will be a lot - and it's a lot - it's a lot better to have a goose that keeps laying eggs than a goose that just sits there and eats insurance and storage and a few things like that.

We try to exert a Ted Williams kind of discipline. In his book The Science of Hitting, Ted explains that he carved the strike zone into 77 cells, each the size of a baseball. Swinging only at balls in his "best" cell, he knew, would allow him to bat .400; reaching for balls in his "worst" spot, the low outside corner of the strike zone, would reduce him to .230. In other words, waiting for the fat pitch would mean a trip to the Hall of Fame; swinging indiscriminately would mean a ticket to the minors.
