In the financial markets, however, the connection between a marketable security and the underlying business is not as clear-cut. For investors in a marketable security the gain or loss associated with the various outcomes is not totally inherent in the underlying business; it also depends on the price paid, which is established by the marketplace. The view that risk is dependent on both the nature of investments and on their market price is very different from that described by beta.

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.

Once you adopt a value-investment strategy, any other investment behavior starts to seem like gambling.

There is an old saying, "How did you go bankrupt?" And the answer is, "Gradually, and then suddenly." The impending fiscal crisis in the United States will make its appearance in the same way.

Value investors have to be patient and disciplined, but what I really think is you need not to be greedy. If you're greedy and you leverage, you blow up. Almost every financial blow up is because of leverage.

Value in relation to price, not price alone, must determine your investment decisions. If you look to Mr Market as a creator of investment opportunities (where price departs from underlying value), you have the makings of a value investor. If you insist on looking to Mr Market for investment guidance however, you are probably best advised to hire someone else to manage your money.

The trick of successful investors is to sell when they want to, not when they have to.
