Concept Questions
S1
1. For both risk and return, increasing order is b, c, a, d. On average, the higher the risk of an
S1 S1 S1 S1 S1 S1 S1 S1 S1 S1 S1 S1 S1 S1 S1 S1 S1 S1 S1
investment, the higher is its expected return.
S1 S1 S1 S1 S1 S1 S1
2. Since the price didn’t change, the capital gains yield was zero.
S1 S1 S1 S1 S1 S1 S1 S1 S1 S1 S 1 If the total return was four
S1 S1 S1 S1 S1
percent, then the dividend yield must be four percent.
S1 S1 S1 S1 S1 S1 S1 S1 S1
3. It is impossible to lose more than –100 percent of your investment. Therefore, return
S1 S1 S1 S1 S1 S1 S1 S1 S1 S1 S1 S1 S1
distributions are cut off on the lower tail at –100 percent; if returns were truly normally
S1 S 1 S1 S1 S1 S1 S1 S1 S1 S1 S1 S1 S1 S1 S1 S1
distributed, you could lose much more.
S1 S1 S1 S1 S1 S1
4. To calculate an arithmetic return, you sum the returns and divide by the number of returns.
S1 S1 S1 S1 S1 S1 S1 S1 S1 S1 S1 S1 S1 S1 S1
As such, arithmetic returns do not account for the effects of compounding (and, in
S1 S1 S1 S1 S1 S1 S1 S1 S1 S1 S1 S1 S1 S1
particular, the effect of volatility). Geometric returns do account for the effects of
S1 S1 S1 S1 S1 S1 S1 S1 S1 S1 S1 S1 S1
compounding and for changes in the base used for each year’s calculation of returns. As an
S1 S1 S1 S1 S1 S1 S1 S1 S1 S1 S1 S1 S1 S1 S1 S1
investor, the more important return of an asset is the geometric return.
S1 S1 S1 S1 S1 S1 S1 S1 S1 S 1 S1 S1
5. Blume’s formula uses the arithmetic and geometric returns along with the number of
S1 S1 S1 S1 S1 S1 S1 S1 S1 S1 S1 S1
observations to approximate a holding period return. When predicting a holding period
S1 S1 S1 S1 S1 S1 S1 S1 S1 S1 S1 S1
return, the arithmetic return will tend to be too high and the geometric return will tend to
S1 S1 S1 S1 S1 S1 S1 S1 S1 S1 S1 S1 S1 S1 S1 S1 S1
be too low. Blume’s formula adjusts these returns for different holding period expected
S1 S1 S1 S1 S1 S1 S1 S1 S1 S1 S1 S1 S1
returns.

6. T-bill rates were highest in the early eighties since inflation at the time was relatively high.
S1 S1 S1 S1 S1 S1 S1 S1 S1 S1 S1 S1 S1 S1 S1
As we discuss in our chapter on interest rates, rates on T-bills will almost always be
S1 S1 S1 S1 S1 S1 S1 S1 S1 S1 S1 S1 S1 S1 S1 S1
slightly higher than the expected rate of inflation.
S1 S1 S1 S1 S1 S1 S1 S1
7. Risk premiums are about the same regardless of whether we account for inflation. The reason
S1 S1 S1 S1 S1 S1 S1 S1 S1 S1 S1 S1 S1 S1
is that risk premiums are the difference between two returns, so inflation essentially nets
S1 S1 S1 S1 S1 S1 S1 S1 S1 S1 S1 S1 S1 S1
out.
S1
8. Returns, risk premiums, and volatility would all be lower than we estimated because aftertax
S1 S1 S1 S1 S1 S1 S1 S1 S1 S1 S1 S1 S1
returns are smaller than pretax returns.
S1 S1 S1 S1 S1 S1
9. We have seen that T-bills barely kept up with inflation before taxes. After taxes, investors in
S1 S1 S1 S1 S1 S1 S1 S1 S1 S1 S1 S1 S1 S1 S1
T-bills actually lost ground (assuming anything other than a very low tax rate). Thus, an all
S1 S1 S1 S1 S1 S1 S1 S1 S1 S1 S1 S1 S1 S1 S1 S1
T-bill strategy will probably lose money in real dollars for a taxable investor.
S1 S1 S1 S1 S1 S1 S1 S1 S1 S1 S1 S1 S1
, 10. It is important not to lose sight of the fact that the results we have discussed cover over 80
S1 S1 S1 S1 S1 S1 S1 S1 S1 S1 S1 S1 S1 S1 S1 S1 S1 S1
years, well beyond the investing lifetime for most of us. There have been extended periods
S1 S 1 S1 S1 S1 S1 S1 S1 S1 S1 S1 S1 S1 S1 S1
during which small stocks have done terribly. Thus, one reason most investors will choose
S1 S1 S1 S1 S1 S1 S1 S1 S1 S1 S1 S1 S1 S1
not to pursue a 100 percent stock (particularly small-cap stocks) strategy is that many
S1 S1 S1 S1 S1 S1 S1 S1 S1 S1 S1 S1 S1 S1
investors have relatively short horizons, and high volatility investments may be very
S1 S1 S1 S1 S1 S1 S1 S1 S1 S1 S1 S1
inappropriate in such cases. There are other reasons, but we will defer discussion of these to
S1 S1 S1 S1 S1 S1 S1 S1 S1 S1 S1 S1 S1 S1 S1 S1
later chapters.

Solutions to Questions and Problems
S1 S1 S1 S1
NOTE: All end of chapter problems were solved using a spreadsheet. Many problems require
S1 S1 S1 S1 S1 S1 S1 S1 S1 S1 S1 S1 S1
multiple steps. Due to space and readability constraints, when these intermediate steps are
S1 S1 S1 S1 S1 S1 S1 S1 S1 S1 S1 S1 S1
included in this solutions manual, rounding may appear to have occurred. However, the final
S1 S1 S1 S1 S1 S1 S1 S1 S1 S1 S1 S1 S1 S1
answer for each problem is found without rounding during any step in the problem.

Core Questions

1. Total dollar return = 100($41 – $37 + $.28) = $428.00
S1 S1 S1 S1 S1 S1 S1 S1 S1 S1
Whether you choose to sell the stock does not affect the gain or loss for the year; your
S1 S1 S1 S1 S1 S1 S1 S1 S1 S1 S1 S1 S1 S1 S1 S1 S1
stock is worth what it would bring if you sold it. Whether you choose to do so or not is
S1 S1 S1 S1 S1 S1 S1 S1 S1 S1 S1 S1 S1 S1 S1 S1 S1 S1 S1 S1
irrelevant (ignoring commissions and taxes).
