The Intelligent Investor_ The Definitive Book on Value Investing - Benjamin Graham [68]
There is no reason at all for thinking that the average intelligent investor, even with much devoted effort, can derive better results over the years from the purchase of growth stocks than the investment companies specializing in this area. Surely these organizations have more brains and better research facilities at their disposal than you do. Consequently we should advise against the usual type of growth-stock commitment for the enterprising investor.* This is one in which the excellent prospects are fully recognized in the market and already reflected in a current price-earnings ratio of, say, higher than 20. (For the defensive investor we suggested an upper limit of purchase price at 25 times average earnings of the past seven years. The two criteria would be about equivalent in most cases.)†
The striking thing about growth stocks as a class is their tendency toward wide swings in market price. This is true of the largest and longest-established companies—such as General Electric and International Business Machines—and even more so of newer and smaller successful companies. They illustrate our thesis that the main characteristic of the stock market since 1949 has been the injection of a highly speculative element into the shares of companies which have scored the most brilliant successes, and which themselves would be entitled to a high investment rating. (Their credit standing is of the best, and they pay the lowest interest rates on their borrowings.) The investment caliber of such a company may not change over a long span of years, but the risk characteristics of its stock will depend on what happens to it in the stock market. The more enthusiastic the public grows about it, and the faster its advance as compared with the actual growth in its earnings, the riskier a proposition it becomes.*
But is it not true, the reader may ask, that the really big fortunes from common stocks have been garnered by those who made a substantial commitment in the early years of a company in whose future they had great confidence, and who held their original shares unwaveringly while they increased 100-fold or more in value? The answer is “Yes.” But the big fortunes from single-company investments are almost always realized by persons who have a close relationship with the particular company—through employment, family connection, etc.—which justifies them in placing a large part of their resources in one medium and holding on to this commitment through all vicissitudes, despite numerous temptations to sell out at apparently high prices along the way. An investor without such close personal contact will constantly be faced with the question of whether too large a portion of his funds are in this one medium.* Each decline—however temporary it proves in the sequel—will accentuate his problem; and internal and external pressures are likely to force him to take what seems to be a goodly profit, but one far less than the ultimate bonanza.4
Three Recommended Fields for “Enterprising Investment”
To obtain better than average investment results over a long pull requires a policy of selection or operation possessing a twofold merit: (1) It must meet objective or rational tests of underlying soundness; and (2) it must be different from the policy followed by most investors or speculators. Our experience and study leads us to recommend three investment approaches that meet these criteria. They differ rather widely from one another, and each may require a different type of knowledge and temperament on the part of those who assay it.
The Relatively Unpopular Large Company
If we assume that it is the habit of the market to overvalue common stocks which have been showing excellent growth or are glamorous
