There are only a few things investors can do to counteract risk: diversify adequately, hedge when appropriate, and invest with a margin of safety. It is a precisely because we do not and cannot know all the risks of an investment that we strive to invest at a discount. The bargain element helps to provide a cushion for when things go wrong.

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.

A tipping point is invisible, as we just saw in Greece. In most situations, everything appears fine until it's not fine, until, for example, no one shows up at a Treasury auction.

Rather, risk is a perception in each investor's mind that results from analysis of the probability and amount of potential loss from an investment. If an exploratory oil well proves to be a dry hole, it is called risky. If a bond defaults or a stock plunges in price, they are called risky. But if the well is a gusher, the bond matures on schedule, and the stock rallies strongly, can we say they weren't risky when the investment after it is concluded than was known when it was made.

The government can indefinitely control both short-term and long-term interest rates.

To value investors the concept of indexing is at best silly and at worst quite hazardous. Warren Buffett has observed that "in any sort of a contest - financial, mental or physical - it's an enormous advantage to have opponents who have been taught that it's useless to even try." I believe that over time value investors will outperform the market and that choosing to match it is both lazy and shortsighted.

We buy expecting to hold a bond to maturity and a stock forever.
