The Intelligent Investor_ The Definitive Book on Value Investing - Benjamin Graham [87]
Incidentally, a widespread situation of this kind actually existed during the dark depression days of 1931–1933. There was then a psychological advantage in owning business interests that had no quoted market. For example, people who owned first mortgages on real estate that continued to pay interest were able to tell themselves that their investments had kept their full value, there being no market quotations to indicate otherwise. On the other hand, many listed corporation bonds of even better quality and greater underlying strength suffered severe shrinkages in their market quotations, thus making their owners believe they were growing distinctly poorer. In reality the owners were better off with the listed securities, despite the low prices of these. For if they had wanted to, or were compelled to, they could at least have sold the issues—possibly to exchange them for even better bargains. Or they could just as logically have ignored the market’s action as temporary and basically meaningless. But it is self-deception to tell yourself that you have suffered no shrinkage in value merely because your securities have no quoted market at all.
Returning to our A. & P. shareholder in 1938, we assert that as long as he held on to his shares he suffered no loss in their price decline, beyond what his own judgment may have told him was occasioned by a shrinkage in their underlying or intrinsic value. If no such shrinkage had occurred, he had a right to expect that in due course the market quotation would return to the 1937 level or better—as in fact it did the following year. In this respect his position was at least as good as if he had owned an interest in a private business with no quoted market for its shares. For in that case, too, he might or might not have been justified in mentally lopping off part of the cost of his holdings because of the impact of the 1938 recession—depending on what had happened to his company.
Critics of the value approach to stock investment argue that listed common stocks cannot properly be regarded or appraised in the same way as an interest in a similar private enterprise, because the presence of an organized security market “injects into equity ownership the new and extremely important attribute of liquidity.” But what this liquidity really means is, first, that the investor has the benefit of the stock market’s daily and changing appraisal of his holdings, for whatever that appraisal may be worth, and, second, that the investor is able to increase or decrease his investment at the market’s daily figure—if he chooses. Thus the existence of a quoted market gives the investor certain options that he does not have if his security is unquoted. But it does not impose the current quotation on an investor who prefers to take his idea of value from some other source.
Let us close this section with something in the nature of a parable. Imagine that in some private business you own a small share that cost you $1,000. One of your partners, named Mr. Market, is very obliging indeed. Every day he tells you what he thinks your interest is worth and furthermore offers either to buy you out or to sell you an additional interest on that basis. Sometimes his idea of value appears plausible and justified by business developments and prospects as you know them. Often, on the other hand, Mr. Market lets his enthusiasm or his fears run away with him, and the value he proposes seems to you a little short of silly.
If you are a prudent investor or a sensible businessman, will you let Mr. Market’s daily communication determine your view of the value of a $1,000 interest in the enterprise? Only in case you agree with him, or in case you want to trade with him. You may be happy to sell out to him when he quotes
