The 5 Components of an Investor's Required Rate of Return
Understanding How Rational Investors Value Cash Flows
In financial theory, the rate of return at which an investment trades is the sum of five different components. Over time, asset prices tend to reflect the impact of these components fairly well. For those of you who want to learn to value stocks or understand why bonds trade at certain prices, this is an important part of the foundation.
The Real Risk-Free Interest Rate
This is the rate to which all other investments are compared. It is the rate of return an investor can earn without any risk in a world with no inflation. Most people reference the three-month U.S. Treasury bill as offering the risk-free rate.
An Inflation Premium
This is the rate that is added to an investment to adjust it for the market’s expectation of future inflation. For example, the inflation premium required for a one-year corporate bond might be a lot lower than a 30-year corporate bond by the same company because investors think that inflation will be low in the short term, but pick up in the future as a result of the trade and budget deficits of years past.
A Liquidity Premium
Some investments don't trade very often, and that presents a risk to the investor. Thinly traded investments such as stocks and bonds in a family-controlled company require a liquidity premium. That is, investors are not going to pay the full value of the asset if there is a very real possibility that they will not be able to dump the stock or bond in a short period of time because buyers are scarce. This is expected to compensate them for that potential loss. The size of the liquidity premium is dependent upon an investor’s perception of how active a particular market is.
Default Risk Premium
Do investors believe a company will default on its obligation or go bankrupt? Often, when signs of trouble appear, a company’s shares or bonds will collapse as a result of investors demanding a default risk premium.
If someone were to acquire assets that were trading at a huge discount as a result of a default risk premium that was too large, they could make a great deal of money.
Many asset management companies actually bought shares of Enron’s corporate debt during the now-famous meltdown of the energy-trading giant. In essence, they bought $1 of debt for only a few pennies. If they can get more than they paid in the event of a liquidation or reorganization, it can make them very, very rich.
K-Mart is another example. Prior to the retailer's 2002 bankruptcy, distressed debt investors bought an enormous portion of its debt. When the company was reorganized in bankruptcy court, the debt holders were given equity in the new company. One such investor, Edward Lampert then used his new controlling block of K-Mart stock with its improved balance sheet to start investing in other assets.
The further in the future the maturity of a company’s bonds, the greater the price will fluctuate when interest rates change. That’s because of the maturity premium. Here’s a very simplified version to illustrate the concept: Imagine you own a $10,000 bond with a 7% yield when it is issued that will mature in 30 years. Each year, you will receive $700 in interest. Thirty years in the future, you will get your original $10,000 back. Now, if you were going to sell your bond the next day, you would likely get around the same amount (minus, perhaps, a liquidity premium as we already discussed).
Consider if interest rates rise to 9%. No investor is going to accept your bond, which is yielding only 7% when they could easily go to the open market and buy a new bond that yields 9%. So, they will only pay a lower price than your bond is worth – not the full $10,000—so that the yield is 9% (say, maybe $7,775.) This is why bonds with longer maturities are subject to a much greater risk of capital gains or losses. Had interest rates fallen, the bondholder would have been able to sell his or her position for much more. If rates fell to 5 percent, then he could have sold for $14,000.
