Commentary On Chapter 1

All of human unhappiness comes from one single thing: not knowing how to remain at rest in a room.   —Blaise Pascal

Graham’s definition of investing could not be clearer: “An investment operation is one which, upon thorough analysis, promises safety of principal and an adequate return.” Note that investing, according to Graham, consists equally of three elements:

• you must thoroughly analyze a company, and the soundness of its underlying businesses, before you buy its stock;

• you must deliberately protect yourself against serious losses;

• you must aspire to “adequate,” not extraordinary, performance.

An investor calculates what a stock is worth, based on the value of its businesses. A speculator gambles that a stock will go up in price because somebody else will pay even more for it. 

As Graham once put it, investors judge “the market price by established standards of value,” while speculators “base [their] standards of value upon the market price.” For a speculator, the incessant stream of stock quotes is like oxygen; cut it off and he dies. For an investor, what Graham called “quotational” values matter much less. Graham urges you to invest only if you would be comfortable owning a stock even if you had no way of knowing its daily share price.

Like casino gambling or betting on the horses, speculating in the market can be exciting or even rewarding (if you happen to get lucky). But it’s the worst imaginable way to build your wealth. That’s because Wall Street, like Las Vegas or the racetrack, has calibrated the odds so that the house always prevails, in the end, against everyone who tries to beat the house at its own speculative game. On the other hand, investing is a unique kind of casino—one where you cannot lose in the end, so long as you play only by the rules that put the odds squarely in your favor. People who invest make money for themselves; people who speculate make money for their brokers. And that, in turn, is why Wall Street perennially downplays the durable virtues of investing and hypes the gaudy appeal of speculation.

People began believing that the test of an investment technique was simply whether it “worked.” If they beat the market over any period, no matter how dangerous or dumb their tactics, people boasted that they were “right.” But the intelligent investor has no interest in being temporarily right. To reach your long-term financial goals, you must be sustainably and reliably right. 

To see why temporarily high returns don’t prove anything, imagine that two places are 130 miles apart. If I observe the 65-mph speed limit, I can drive that distance in two hours. But if I drive 130 mph, I can get there in one hour. If I try this and survive, am I “right”? Should you be tempted to try it, too, because you hear me bragging that it “worked”? Flashy gimmicks for beating the market are much the same: In short streaks, so long as your luck holds out, they work. Over time, they will get you killed.
