Overview
The concepts of return and risk are developed in this chapter. This chapter is conceptually more
demanding than the preceding one, so the instructor should plan to spend more class time on it.
1. Returns are rewards for investing. The components of total return are income and capital gains (or
losses). Income is cash received for holding an investment, whereas capital gains refers to income
that is attributed to an increaserealized or unrealizedin the value of the investment.
2. Expected return motivates a person to invest in a particular vehicle. Expectations of returns are based
on the past returns of that vehicle. Measuring the historical return of a particular investment reveals
its average return as well as the trend of its returns.
3. The level of returns for a particular investment vehicle depends on internal characteristics, such
4. A satisfactory investment is one in which the present value (PV) of benefits (discounted at the
5. The required return of an investment is the rate that compensates the investor for its risk. It is
6. The holding period return (HPR), defined next, is useful in making investment decisions. The
instructor may show the class how HPR is computed, stressing that the HPR from identical periods
should be used when comparing two investments.
Chapter 4 Return and Risk 53
History tells us that stock market returns have averaged well above the interest rates payable on
3. Ignoring risk, a satisfactory investment is one for which the present value of benefits (discounted)
4. (a) The real rate of return is the return earned in a certain, risk-free world. It would equal the
nominal rate of return on a risk-free security less inflation. Historically, it has been relatively
The required rate of return equals the real rate of return plus the expected inflation premium
5. The holding period is simply the period of time over which the investor wishes to measure the return
on an investment. In comparing alternative investments, it is essential to use equal-length holding
6. The yield, or IRR, is the annual rate of return earned by a long-term investment. It is also defined as

(g) Event risk is the risk that comes from a largely or totally unexpected event that has a significant
and usually immediate effect on the underlying value of an investment. The effect of this risk
seems to be isolated in most cases, affecting only certain companies and properties.
(h) Market risk is the risk of changes in investment returns caused by factors independent of the
given investment vehicle. It results from factors such as political, economic, and social events, or
changes in investor tastes and preferences.
11. Standard deviation is the most common measure of an asset’s risk. It measures the dispersion of
12. Investors’ attitudes toward risk or their risk-return trade-offs may be classified as one of the following:
Risk-indifferent investors do not require a greater return in exchange for each unit of additional risk.
13. The investment process can be summarized in four steps:
(1) Estimate the expected return over a given holding period using historical data or projected return
data, or both. The time value of these returns must be considered for long-term investments.

(c) Students should be made aware of the fact that many other forecasts are possible. Other factors
may be relevant here: Will the pattern of two good years followed by a bad one continue? Do
future prospects seem bright? (We will discuss forecasting returns on specific investments in
later chapters.)

increases by 1%, then the risk-free rate will increase by 1% to 8%.

Chapter 4 Return and Risk 59
If the investments are held beyond a year, the capital gain (or loss) component would not be realized
and would likely change. Assuming they are of equal risk, Investment Y would be preferred since it
offers the higher return (16.00% for Y versus 11.67% for X).
10. HPR = (Income over the period + Capital gains)/Beginning investment value
The first investment provides the higher annualized return.
12. The present value is $5,000. The value in 10 years will be $9,000.

From Table A.3, Appendix A, at 10 years the PVIF of 6% is 0.558, which is very close to 0.556.
The yield, then, is estimated to be 6%. (Calculator solution is 6.05%).
(b) If a minimum return of 9% is required, this investment would not be recommended because it
only yields about 6%.
13. Using a present value interest factor of 4%:

Chapter 4 Return and Risk 61
The closest interest rate to 3.167 in Table A.4, Appendix A, is 17%. Because the larger cash flows are
received in the later years, 16% is a good starting point.

rate. Because the larger cash flows occur in the early years, 8% is a good starting point.

The yield is very close to 11% on this investment.
Since the yield of 11% is greater than the minimum required return of 9%, the investment is
recommended. This project would result in positive net present value to the investor.
