The availability of a risk-free asset greatly simplifies the portfolio decision. When all investors can borrow and lend at that risk-free rate, we are led to a unique optimal risky portfolio that is appropriate for all investors given a common input list. This portfolio maximizes the reward-to-variability ratio. All investors use the same risky portfolio and differ only in the proportion they invest in it versus in the risk-free asset.

What if a risk-free asset is not available? Although T-bills are risk-free assets in nominal terms, their real returns are uncertain. Without a risk-free asset, there is no tangency portfolio that is best for all investors. In this case investors have to choose a portfolio from the efficient frontier of risky assets redrawn in Figure 8.15.

Each investor will now choose an optimal risky portfolio by superimposing a personal set of indifference curves on the efficient frontier as in Figure 8.15. An investor with indifference curves marked U', U", and U" in Figure 8.15 will choose Portfolio P. More risk-averse investors with steeper indifference curves will choose portfolios with lower means and smaller standard deviations such as Portfolio Q, while more risk-tolerant investors will choose portfolios with higher means and greater risk, such as Portfolio S. The common feature of all these investors is that each chooses portfolios on the efficient frontier.

Even if virtually risk-free lending opportunities are available, many investors do face borrowing restrictions. They may be unable to borrow altogether, or, more realistically, they may face a borrowing rate that is significantly greater than the lending rate.

When a risk-free investment is available, but an investor cannot borrow, a CAL exists but is limited to the line FP as in Figure 8.16. Any investors whose preferences are represented by indifference curves with tangency portfolios on the portion FP of the CAL, such as Portfolio A, are unaffected by the borrowing restriction. Such investors are net lenders at rate f

Aggressive or more risk-tolerant investors, who would choose Portfolio B in the absence of the borrowing restriction, are affected, however. Such investors will be driven to portfolios such as Portfolio Q, which are on the efficient frontier of risky assets. These investors will not invest in the risk-free asset.

In more realistic scenarios, individuals who wish to borrow to invest in a risky portfolio will have to pay an interest rate higher than the T-bill rate. For example, the call money rate charged by brokers on margin accounts is higher than the T-bill rate.

Investors who face a borrowing rate greater than the lending rate confront a three-part CAL such as in Figure 8.17. CAL1, which is relevant in the range FP1, represents the efficient

portfolio set for defensive (risk-averse) investors. These investors invest part of their funds in T-bills at rate f They find that the tangency Portfolio is P1, and they choose a complete portfolio such as Portfolio A in Figure 8.18.

CALp, which is relevant in a range to the right of Portfolio Pp, represents the efficient portfolio set for more aggressive, or risk-tolerant, investors. This line starts at the borrowing rate rf, but it is unavailable in the range rfP p, because lending (investing in T-bills) is available only at the risk-free rate r, which is less than rf.

Investors who are willing to borrow at the higher rate, rf, to invest in an optimal risky portfolio will choose Portfolio P2 as the risky investment vehicle. Such a case is depicted

in Figure 8.19, which superimposes a relatively risk-tolerant investor's indifference curve on CAL2. The investor with the indifference curve in Figure 8.19 chooses Portfolio P2 as the optimal risky portfolio and borrows to invest in it, arriving at the complete Portfolio B.

Investors in the middle range, neither defensive enough to invest in T-bills nor aggressive enough to borrow, choose a risky portfolio from the efficient frontier in the range P1P2. This case is depicted in Figure 8.20. The indifference curve representing the investor in Figure 8.20 leads to a tangency portfolio on the efficient frontier, Portfolio C.

PART II Portfolio Theory

CONCEPT CHECK ^ QUESTION 5

With differential lending and borrowing rates, only investors with about average degrees of risk aversion will choose a portfolio in the range P1P2 in Figure 8.18. Other investors will choose a portfolio on CAL1 if they are more risk averse, or on CAL2 if they are more risk tolerant.

a. Does this mean that investors with average risk aversion are more dependent on the quality of the forecasts that generate the efficient frontier?

b. Describe the trade-off between expected return and standard deviation for portfolios between P1 and P2 in Figure 8.18 compared with portfolios on CAL2 beyond P2.

SUMMARY

1. The expected return of a portfolio is the weighted average of the component security expected returns with the investment proportions as weights.

2. The variance of a portfolio is the weighted sum of the elements of the covariance matrix with the product of the investment proportions as weights. Thus the variance of each asset is weighted by the square of its investment proportion. Each covariance of any pair of assets appears twice in the covariance matrix; thus the portfolio variance includes twice each covariance weighted by the product of the investment proportions in each of the two assets.

3. Even if the covariances are positive, the portfolio standard deviation is less than the weighted average of the component standard deviations, as long as the assets are not perfectly positively correlated. Thus portfolio diversification is of value as long as assets are less than perfectly correlated.

4. The greater an asset's covariance with the other assets in the portfolio, the more it contributes to portfolio variance. An asset that is perfectly negatively correlated with a portfolio can serve as a perfect hedge. The perfect hedge asset can reduce the portfolio variance to zero.

5. The efficient frontier is the graphical representation of a set of portfolios that maximize expected return for each level of portfolio risk. Rational investors will choose a portfolio on the efficient frontier.

6. A portfolio manager identifies the efficient frontier by first establishing estimates for the asset expected returns and the covariance matrix. This input list is then fed into an optimization program that reports as outputs the investment proportions, expected returns, and standard deviations of the portfolios on the efficient frontier.

7. In general, portfolio managers will arrive at different efficient portfolios because of differences in methods and quality of security analysis. Managers compete on the quality of their security analysis relative to their management fees.

8. If a risk-free asset is available and input lists are identical, all investors will choose the same portfolio on the efficient frontier of risky assets: the portfolio tangent to the CAL. All investors with identical input lists will hold an identical risky portfolio, differing only in how much each allocates to this optimal portfolio and to the risk-free asset. This result is characterized as the separation principle of portfolio construction.

9. When a risk-free asset is not available, each investor chooses a risky portfolio on the efficient frontier. If a risk-free asset is available but borrowing is restricted, only aggressive investors will be affected. They will choose portfolios on the efficient frontier according to their degree of risk tolerance.

PROBLEMS

The following data apply to problems 1 through 8:

A pension fund manager is considering three mutual funds. The first is a stock fund, the second is a long-term government and corporate bond fund, and the third is a T-bill money market fund that yields a rate of 8%. The probability distribution of the risky funds is as follows:

The correlation between the fund returns is .10.

1. What are the investment proportions in the minimum-variance portfolio of the two risky funds, and what is the expected value and standard deviation of its rate of return?

2. Tabulate and draw the investment opportunity set of the two risky funds. Use investment proportions for the stock funds of zero to 100% in increments of 20%.

3. Draw a tangent from the risk-free rate to the opportunity set. What does your graph show for the expected return and standard deviation of the optimal portfolio?

4. Solve numerically for the proportions of each asset and for the expected return and standard deviation of the optimal risky portfolio.

5. What is the reward-to-variability ratio of the best feasible CAL?

6. You require that your portfolio yield an expected return of 14%, and that it be efficient on the best feasible CAL.

a. What is the standard deviation of your portfolio?

b. What is the proportion invested in the T-bill fund and each of the two risky funds?

7. If you were to use only the two risky funds, and still require an expected return of 14%, what must be the investment proportions of your portfolio? Compare its standard deviation to that of the optimized portfolio in problem 6. What do you conclude?

8. Suppose that you face the same opportunity set, but you cannot borrow. You wish to construct a portfolio of only stocks and bonds with an expected return of 24%. What

a. In light of the apparent inferiority of gold with respect to both mean return and volatility, would anyone hold gold? If so, demonstrate graphically why one would do so.

b. Given the data above, reanswer (a) with the additional assumption that the correlation coefficient between gold and stocks equals 1. Draw a graph illustrating why one would or would not hold gold in one's portfolio. Could this set of assumptions for expected returns, standard deviations, and correlation represent an equilibrium for the security market?

Suppose that it is possible to borrow at the risk-free rate, r. What must be the value of the risk-free rate? (Hint: Think about constructing a risk-free portfolio from Stocks A and B.)

Assume that expected returns and standard deviations for all securities (including the risk-free rate for borrowing and lending) are known. In this case all investors will have the same optimal risky portfolio. (True or false?)

The standard deviation of the portfolio is always equal to the weighted average of the standard deviations of the assets in the portfolio. (True or false?) Suppose you have a project that has a .7 chance of doubling your investment in a year and a .3 chance of halving your investment in a year. What is the standard deviation of the rate of return on this investment? 14. Suppose that you have $1 million and the following two opportunities from which to construct a portfolio:

a. Risk-free asset earning 12% per year.

b. Risky asset earning 30% per year with a standard deviation of 40%.

If you construct a portfolio with a standard deviation of 30%, what will be the rate of return?

The following data apply to problems 15 through 17.

Hennessy & Associates manages a $30 million equity portfolio for the multimanager Wilstead Pension Fund. Jason Jones, financial vice president of Wilstead, noted that Hennessy had rather consistently achieved the best record among the Wilstead's six equity managers. Performance of the Hennessy portfolio had been clearly superior to that of the S&P 500 in four of the past five years. In the one less-favorable year, the shortfall was trivial.

Hennessy is a "bottom-up" manager. The firm largely avoids any attempt to "time the market." It also focuses on selection of individual stocks, rather than the weighting of favored industries.

Bodie-Kane-Marcus: Investments, Fifth Edition

CHAPTER 8 Optimal Risky Portfolios

There is no apparent conformity of style among the six equity managers. The five managers, other than Hennessy, manage portfolios aggregating $250 million made up of more than 150 individual issues.

Jones is convinced that Hennessy is able to apply superior skill to stock selection, but the favorable returns are limited by the high degree of diversification in the portfolio. Over the years, the portfolio generally held 40-50 stocks, with about 2%-3% of total funds committed to each issue. The reason Hennessy seemed to do well most years was because the firm was able to identify each year 10 or 12 issues which registered particularly large gains.

Based on this overview, Jones outlined the following plan to the Wilstead pension committee:

Let's tell Hennessy to limit the portfolio to no more than 20 stocks. Hennessy will double the commitments to the stocks that it really favors, and eliminate the remainder. Except for this one new restriction, Hennessy should be free to manage the portfolio exactly as before.

All the members of the pension committee generally supported Jones's proposal because all agreed that Hennessy had seemed to demonstrate superior skill in selecting stocks. Yet the proposal was a considerable departure from previous practice, and several committee members raised questions. Respond to each of the following questions.

15. a. Will the limitations of 20 stocks likely increase or decrease the risk of the portfolio?

Explain.

b. Is there any way Hennessy could reduce the number of issues from 40 to 20 without significantly affecting risk? Explain.

16. One committee member was particularly enthusiastic concerning Jones's proposal. He suggested that Hennessy's performance might benefit further from reduction in the number of issues to 10. If the reduction to 20 could be expected to be advantageous, explain why reduction to 10 might be less likely to be advantageous. (Assume that Wilstead will evaluate the Hennessy portfolio independently of the other portfolios in the fund.)

17. Another committee member suggested that, rather than evaluate each managed portfolio independently of other portfolios, it might be better to consider the effects of a change in the Hennessy portfolio on the total fund. Explain how this broader point of view could affect the committee decision to limit the holdings in the Hennessy portfolio to either 10 or 20 issues.

The following data are for problems 18 through 20.

The correlation coefficients between pairs of stocks are as follows: Corr(A,B) = .85; Corr(A,C) = .60; Corr(A,D) = .45. Each stock has an expected return of 8% and a standard deviation of 20%.

18. If your entire portfolio is now composed of Stock A and you can add some of only one stock to your portfolio, would you choose (explain your choice):

d. Need more data.

19. Would the answer to problem 18 change for more risk-averse or risk-tolerant investors? Explain.

20. Suppose that in addition to investing in one more stock you can invest in T-bills as well. Would you change your answers to problems 18 and 19 if the T-bill rate is

2. The parameters of the opportunity set are E(rD) = 8%, E(rE) = 13%, jd = 12%, je = 20%, and p (D,E) = 25. From the standard deviations and the correlation coefficient we generate the covariance matrix:

For the other points we simply increase wD from .10 to .90 in increments of .10; accordingly, wE ranges from .90 to .10 in the same increments. We substitute these portfolio proportions in the formulas for expected return and standard deviation. Note that when wE = 1.0, the portfolio parameters equal those of the stock fund; when wD = 1, the portfolio parameters equal those of the debt fund. We then generate the following table:

The expected return and standard deviation of the optimal risky portfolio are

ctp = {(.68182 X 202) + (.31822 X 602) + [2 X .6818 X .3182(-240)]}1/2 = 21.13%

Note that in this case the standard deviation of the optimal risky portfolio is smaller than the standard deviation of stock A. Note also that portfolio P is not the global minimum-variance portfolio. The proportions of the latter are given by

E(rp) - rf = 16.36 - 5 = y = .01 X Aup .01 X 5 X 21.132

This means that the optimal risky portfolio, with the given data, is attractive enough for an investor with A = 5 to invest 50.89% of his or her wealth in it. Since stock A makes up 68.18% of the risky portfolio and stock B makes up 31.82%, the investment proportions for this investor are

Stock A: .5089 X 68.18 = 34.70% Stock B: .5089 X 31.82 = 16.19%

Total 50.89%

4. Efficient frontiers derived by portfolio managers depend on forecasts of the rates of return on various securities and estimates of risk, that is, the covariance matrix. The forecasts themselves do not control outcomes. Thus preferring managers with rosier forecasts (northwesterly frontiers) is tantamount to rewarding the bearers of good news and punishing the bearers of bad news. What we should do is reward bearers of accurate news. Thus if you get a glimpse of the frontiers (forecasts) of portfolio managers on a regular basis, what you want to do is develop the track record of their forecasting accuracy and steer your advisees toward the more accurate forecaster. Their portfolio choices will, in the long run, outperform the field.

5. a. Portfolios that lie on the CAL are combinations of the tangency (optimal risky)

portfolio and the risk-free asset. Hence they are just as dependent on the accuracy of the efficient frontier as portfolios that are on the frontier itself. If we judge forecasting accuracy by the accuracy of the reward-to-variability ratio, then all portfolios on the CAL will be exactly as accurate as the tangency portfolio. b. All portfolios on CAL1 are combinations of portfolio P1 with lending (buying T-bills). This combination of one risky asset with a risk-free asset leads to a linear relationship between the portfolio expected return and its standard deviation:

The same applies to all portfolios on CAL2; just replace E(rpi), op in equation 5.b with E(rp2), up2.

An investor who wishes to have an expected return between E(rP ) and E(rP ) must find the appropriate portfolio on the efficient frontier of risky assets between p1 and p2 in the correct proportions.
