High-yield bonds—which Graham calls “second-grade” or “lower-grade” and today are called “junk bonds”—get a brisk thumbs-down from Graham. In his day, it was too costly and cumbersome for an individual investor to diversify away the risks of default.;1 (To learn how bad a default can be, and how carelessly even “sophisticated” professional bond investors can buy into one, see the sidebar on p. 146.) Today, however, more than 130 mutual funds specialize in junk bonds. These funds buy junk by the cartload; they hold dozens of different bonds. That mitigates Graham’s complaints about the difficulty of diversifying. (However, his bias against high-yield preferred stock remains valid, since there remains no cheap and widely available way to spread their risks.) Since 1978, an annual average of 4.4% of the junk-bond market has gone into default—but, even after those defaults, junk bonds have still produced an annualized return of 10.5%, versus 8.6% for 10-year U.S. Treasury bonds.2 Unfortunately, most junk-bond funds charge high fees and do a poor job of preserving the original principal amount of your investment. A junk fund could be appropriate if you are retired, are looking for extra monthly income to supplement your pension, and can tolerate temporary tumbles in value. If you work at a bank or other financial company, a sharp rise in interest rates could limit your raise or even threaten your job security—so a junk fund, which tends to outper-forms most other bond funds when interest rates rise, might make sense as a counterweight in your 401(k). A junk-bond fund, though, is only a minor option—not an obligation—for the intelligent investor.
