The strategy of buying what's in favor is a fool's errand, ensuring long-term underperformance. Only by standing against the prevailing winds - selectively, but resolutely - can an investor prosper over time. But for a while, a value investor typically underperforms.

The stock market is the story of cycles and of the human behavior that is responsible for overreactions in both directions.

Value investing is the discipline of buying shares at a significant discount from their current underlying values and holding them until more of their value is realised. The element of a bargain is the key to the process.

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.

It sounds kind of crazy, but in times of turmoil in the market, I've felt a sort of serenity in knowing that I've checked and re-checked my work, one plus one still equals two regardless of where a stock trades right after I buy it.

The real secret to investing is that there is no secret to investing.

Value investing is predicated on the efficient market hypothesis being wrong.
