The Intelligent Investor_ The Definitive Book on Value Investing - Benjamin Graham [80]
The investor should know about these possibilities and should be prepared for them both financially and psychologically. He will want to benefit from changes in market levels—certainly through an advance in the value of his stock holdings as time goes on, and perhaps also by making purchases and sales at advantageous prices. This interest on his part is inevitable, and legitimate enough. But it involves the very real danger that it will lead him into speculative attitudes and activities. It is easy for us to tell you not to speculate; the hard thing will be for you to follow this advice. Let us repeat what we said at the outset: If you want to speculate do so with your eyes open, knowing that you will probably lose money in the end; be sure to limit the amount at risk and to separate it completely from your investment program.
We shall deal first with the more important subject of price changes in common stocks, and pass later to the area of bonds. In Chapter 3 we supplied a historical survey of the stock market’s action over the past hundred years. In this section we shall return to that material from time to time, in order to see what the past record promises the investor—in either the form of long-term appreciation of a portfolio held relatively unchanged through successive rises and declines, or in the possibilities of buying near bear-market lows and selling not too far below bull-market highs.
Market Fluctuations as a Guide to Investment Decisions
Since common stocks, even of investment grade, are subject to recurrent and wide fluctuations in their prices, the intelligent investor should be interested in the possibilities of profiting from these pendulum swings. There are two possible ways by which he may try to do this: the way of timing and the way of pricing. By timing we mean the endeavor to anticipate the action of the stock market—to buy or hold when the future course is deemed to be upward, to sell or refrain from buying when the course is downward. By pricing we mean the endeavor to buy stocks when they are quoted below their fair value and to sell them when they rise above such value. A less ambitious form of pricing is the simple effort to make sure that when you buy you do not pay too much for your stocks. This may suffice for the defensive investor, whose emphasis is on long-pull holding; but as such it represents an essential minimum of attention to market levels.1
We are convinced that the intelligent investor can derive satisfactory results from pricing of either type. We are equally sure that if he places his emphasis on timing, in the sense of forecasting, he will end up as a speculator and with a speculator’s financial results. This distinction may seem rather tenuous to the layman, and it is not commonly accepted on Wall Street. As a matter of business practice, or perhaps of thoroughgoing conviction, the stock brokers and the investment services seem wedded to the principle that both investors and speculators in common stocks should devote careful attention to market forecasts.
The farther one gets from Wall Street, the more skepticism one will find, we believe, as to the pretensions of stock-market forecasting or timing. The investor can scarcely take seriously the innumerable predictions which appear almost daily and are his for the asking. Yet in many cases he pays attention to them and even acts upon them. Why? Because he has been persuaded that it is important for him to form some opinion of the future course of the stock market, and because he feels that the brokerage or service forecast is at least more dependable than his own.11
