from the Berkshire Hathaway 1994 annual report by Warren Buffett
We will continue to ignore political and economic forecasts, which are an expensive distraction for many investors and businessmen. Thirty years ago, no one could have foreseen the huge expansion of the Vietnam War, wage and price controls, two oil shocks, the resignation of a president, the dissolution of the Soviet Union, a one-day drop in the Dow of 508 points, or treasury bill yields fluctuating between 2.8% and 17.4%.
But, surprise -- none of these blockbuster events made the slightest dent in Ben Graham's investment principles.... Fear is the foe of the faddist, but the friend of the fundamentalist.
A different set of major shocks is sure to occur in the next 30 years. We will neither try to predict these nor to profit from them.
