Let's go back to the first one, though, and the 60/40 end of a proposition. There's three sources of competitive advantage in investing: informational, analytical and behavioral.
Informational is - well, let's say you manage money for a Middle Eastern government, and you go over there and the oil minister tells you that they're going to double oil production in the next three months, you know something other people don't know.
But informational advantages are very difficult to get. They're difficult for two independent reasons. Number one, the [U.S.] government tries to keep you from getting them, because they want a level playing field. There are rules against inside information and acting on it. People know when companies are going to release their earnings, and there's supposed to be equal access to that information. And then the hedge funds are the other independent reason. Many of them are trying to get an informational advantage. With so many of them out there doing this full time, it's very difficult for people to get an informational advantage - even other professionals such as ourselves.
The second category is analytical advantages. This is where you know the same things that other people know, but you weight them differently, you give them different probabilities. And that can happen a lot. If you've owned the company over a long period of time, you can get a sense of how their business is evolving, how their capital allocation is going to work, that other people aren't thinking about. And you might have a different sense of their risk, the risk in assessing the investment. So the analytical advantage involves different probabilistic weights on the same information that other people have.
And then the third one is behavioral. And that's the most enduring, because behavioral advantages arise out of the manifest tendencies of large numbers of people to react in predictable ways to certain kinds of situations. So we know that people are risk averse. We know that their coefficient of loss is about two to one - which means that they feel the pain of losing a dollar twice as intensely as they feel the pleasure of gaining a dollar.
Question: Correct.
Answer: People overweight the most recent information. They overreact to dramatic information, or dramatic circumstances. They tend to have what's called outcome bias, which is they judge things on their outcome, and not on their process. So a lot of these behavioral elements are things that you can actually identify and exploit to your advantage if you are aware of them - and aware also that no matter how much you're aware of them, you're not immune to them yourself. You really have to have a sense of discipline and patience, and understanding in that.
