The Intelligent Investor_ The Definitive Book on Value Investing - Benjamin Graham [59]
Many investors buy securities of this kind because they “need income” and cannot get along with the meager return offered by top-grade issues. Experience clearly shows that it is unwise to buy a bond or a preferred which lacks adequate safety merely because the yield is attractive.* (Here the word “merely” implies that the issue is not selling at a large discount and thus does not offer an opportunity for a substantial gain in principal value.) Where such securities are bought at full prices—that is, not many points under 100 * —the chances are very great that at some future time the holder will see much lower quotations. For when bad business comes, or just a bad market, issues of this kind prove highly susceptible to severe sinking spells; often interest or dividends are suspended or at least endangered, and frequently there is a pronounced price weakness even though the operating results are not at all bad.
As a specific illustration of this characteristic of second-quality senior issues, let us summarize the price behavior of a group of ten railroad income bonds in 1946–47. These comprise all of those which sold at 96 or more in 1946, their high prices averaging 102½. By the following year the group had registered low prices averaging only 68, a loss of one-third of the market value in a very short time. Peculiarly enough, the railroads of the country were showing much better earnings in 1947 than in 1946; hence the drastic price decline ran counter to the business picture and was a reflection of the selloff in the general market. But it should be pointed out that the shrinkage in these income bonds was proportionately larger than that in the common stocks in the Dow Jones industrial list (about 23%). Obviously the purchaser of these bonds at a cost above 100 could not have expected to participate to any extent in a further rise in the securities market. The only attractive feature was the income yield, averaging about 4.25% (against 2.50% for first-grade bonds, an advantage of 1.75% in annual income). Yet the sequel showed all too soon and too plainly that for the minor advantage in annual income the buyer of these second-grade bonds was risking the loss of a substantial part of his principal.
The above example permits us to pay our respects to the popular fallacy that goes under the sobriquet of a “businessman’s investment.” That involves the purchase of a security showing a larger yield than is obtainable on a high-grade issue and carrying a correspondingly greater risk. It is bad business to accept an acknowledged possibility of a loss of principal in exchange for a mere 1 or 2% of additional yearly income. If you are willing to assume some risk you should be certain that you can realize a really substantial gain in principal value if things go well. Hence a second-grade 5.5 or 6% bond selling at par is almost always a bad purchase. The same issue at 70 might make more sense—and if you are patient you will probably be able to buy it at that level.
Second-grade bonds and preferred stocks possess two contradictory attributes which the intelligent investor must bear clearly in mind. Nearly all suffer severe sinking spells in bad markets. On the other hand, a large proportion recover their position when favorable conditions return, and these ultimately “work out all right.” This is true even of (cumulative) preferred stocks that fail to pay dividends for many years. There were a number of such issues in the early 1940s, as a consequence of the long depression of the 1930s. During the postwar boom period of 1945–1947 many of these large accumulations were paid off either in cash or in new securities, and the principal was often discharged as well. As a result, large profits were made by people who, a few years previously, had bought these issues when they were friendless and sold at low prices.2
It may well be true that, in an overall accounting, the higher yields obtainable on second-grade senior issues will prove to have offset those principal losses that were irrecoverable.
