Investors should always keep in mind that the most important metric is not the returns achieved but the returns weighed against the risks incurred. Ultimately, nothing should be more important to investors than the ability to sleep soundly at night.

You must buy on the way down. There is far more volume on the way down than on the way back up, and far less competition among buyers. It is almost always better to be too early than too late, but you must be prepared for price markdowns on what you buy.

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.

Gold is unique because it has the age-old aspect of being viewed as a store of value. Nevertheless, it’s still a commodity and has no tangible value, and so I would say that gold is a speculation. But because of my fear about the potential debasing of paper money and about paper money not being a store of value, I want some exposure to gold.

Bailouts and rescues are likely to occur, though not with sufficient predictability for investors to comfortably take advantage. The government will take enormous risks in such interventions, especially if the expenses can be conveniently deferred to the future. Some of the price-tag is in the form of back- stops and guarantees, whose cost is almost impossible to determine.
