Below, we itemize some of the quite different lessons investors seem to have learned as of late 2009 - false lessons, we believe. To not only learn but also effectively implement investment lessons requires a disciplined, often contrary, and long-term-oriented investment approach. It requires a resolute focus on risk aversion rather than maximizing immediate returns, as well as an understanding of history, a sense of financial market cycles, and, at times, extraordinary patience.

If an asset has cash flow or the likelihood of cash flow in the near term and is not purely dependment on what a future buyer might pay, then it's an investment. If an asset's value is totally dependent on the amount a future buyer might pay, then its purchase is speculation.

Investors need to pick their poison: Either make more money when times are good and have a really ugly year every so often, or protect on the downside and don't be at the party so long when things are good.

Frequent comparative ranking can only reinforce a short-term investment perspective. It is understandably difficult to maintain a long-term view when, faced with the penalties for poor short-term performance, the long-term view may well be from the unemployment line ... Relative-performance-oriented investors really act as speculators. Rather than making sensible judgments about the attractiveness of specific stocks and bonds, they try to guess what others are going to do and then do it first.

One thing I want to emphasize is that, like any human being, we can discuss our view of the economy and the market. Fortunately for our clients, we don't tend to operate based on the view. Our investment strategy is to invest bottom up, one stock at a time, based on price compared to value. And while we may have a macro view that things aren't very good right now - which in fact we feel very strongly we will put money to work regardless of that macro view if we find bargains. So tomorrow, if we found half a dozen bargains, we would invest all our cash.

The government can reasonably rely on debt ratings when it forms programs to lend money to buyers of otherwise unattractive debt instruments.

You need humility to say 'I might be wrong.'
