The latest trade of a security creates a dangerous illusion that its market price approximates its true value. This mirage is especially dangerous during periods of market exuberance. The concept of "private market value" as an anchor to the proper valuation of a business can also be greatly skewed during ebullient times and should always be considered with a healthy degree of skepticism.

In a rising market, everyone makes money and a value philosophy is unnecessary. But because there is no certain way to predict what the market will do, one must follow a value philosophy at all times.

(Investors believe this now and, worse still, the government believes it as well. We are probably doomed to a lasting legacy of government tampering with financial markets and the economy, which is likely to create the mother of all moral hazards.
