Occasionally we are asked whether it would make sense to modify our investment strategy to perform better in today's financial climate. Our answer, as you might guess, is: No! It would be easyfor us to capitulate to the runaway bull market in growth and technology stocks. And foolhardy. And irresponsible. And unconscionable. It is always easiest to run with the herd; at times, it can take a deep reservoir of courage and conviction to stand apart from it. Yet distancing yourself from the crowd is an essential component of long-term investment success.

Targeting investment returns leads investors to focus on potential upside rather on downside risk ... rather than targeting a desired rate of return, even an eminently reasonable one, investors should target risk.

Unlike return, however, risk is no more quantifiable at the end of an investment that it was at its beginning. Risk simply cannot be described by a single number. Intuitively we understand that risk varies from investment to investment: a government bond is not as risky as the stock of a high-technology company. But investments do not provide information about their risks the way food packages provide nutritional data.

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.
