The Intelligent Investor_ The Definitive Book on Value Investing - Benjamin Graham [17]
There is also a fairly wide group of “special situations,” which over many years could be counted on to bring a nice annual return of 20% or better, with a minimum of overall risk to those who knew their way around in this field. They include intersecurity arbitrages, payouts or workouts in liquidations, protected hedges of certain kinds. The most typical case is a projected merger or acquisition which offers a substantially higher value for certain shares than their price on the date of the announcement. The number of such deals increased greatly in recent years, and it should have been a highly profitable period for the cognoscenti. But with the multiplication of merger announcements came a multiplication of obstacles to mergers and of deals that didn’t go through; quite a few individual losses were thus realized in these once-reliable operations. Perhaps, too, the overall rate of profit was diminished by too much competition.†
The lessened profitability of these special situations appears one manifestation of a kind of self-destructive process—akin to the law of diminishing returns—which has developed during the lifetime of this book. In 1949 we could present a study of stock-market fluctuations over the preceding 75 years, which supported a formula—based on earnings and current interest rates—for determining a level to buy the DJIA below its “central” or “intrinsic” value, and to sell out above such value. It was an application of the governing maxim of the Rothschilds: “Buy cheap and sell dear.”* And it had the advantage of running directly counter to the ingrained and pernicious maxim of Wall Street that stocks should be bought because they have gone up and sold because they have gone down. Alas, after 1949 this formula no longer worked. A second illustration is provided by the famous “Dow Theory” of stock-market movements, in a comparison of its indicated splendid results for 1897–1933 and its much more questionable performance since 1934.
A third and final example of the golden opportunities not recently available: A good part of our own operations on Wall Street had been concentrated on the purchase of bargain issues easily identified as such by the fact that they were selling at less than their share in the net current assets (working capital) alone, not counting the plant account and other assets, and after deducting all liabilities ahead of the stock. It is clear that these issues were selling at a price well below the value of the enterprise as a private business. No proprietor or majority holder would think of selling what he owned at so ridiculously low a figure. Strangely enough, such anomalies were not hard to find. In 1957 a list was published showing nearly 200 issues of this type available in the market. In various ways practically all these bargain issues turned out to be profitable, and the average annual result proved much more remunerative than most other investments. But they too virtually disappeared from the stock market in the next decade, and with them a dependable area for shrewd and successful operation
