[1] Financial assets are often classified into three major classes which are the fixed income securities, equities and

derivatives. An example of derivatives is the stock option which is a contract whose value is derived from the

price of underlying stock. Options are traded in the market and the Options Clearing Corporation (OCC) serves as

an intermediary in the transaction. That is, buyers and sellers of options buy from and sell to the OCC. The buyer

of call option has the (i), but no (ii), to (iii) specified number of shares of the underlying stock at a (iv) price by

the (v) date. The seller of call option has the (vi) to (vii) the share if the holder (viii) the option.

[2] 1The price of XYZ stock is $201.09, and the bid/ask prices of call and put options on this stock which expire

in two months are shown below (all in dollars).

Call option Put option

If you buy an option, the price you pay is the (i) price and if you sell an option, the price you receive is the (ii)

price. Suppose you expect that the price of XYZ stock will be $195 by the expiration date. Will you buy a call

option? The short answer is (iii). This can be explained as follows: If you buy a call option, you pay (iv) for the

option. If price reaches your expected price of $195, the option is (v) money. So, you (vi) the option. If you

exercise the option, you pay the strike price $180 and receive a share of stock. Then you sell it in the market at

price $195, making a profit of $15 from this transaction. Your net profit is (vii). Therefore, you will (viii) the call

option if you expect the stock price will be $195. If you do not exercise option, your net profit is (ix).

(vi) (exercise, don’t exercise) (vii) (viii) (buy, not buy) (ix)

[3] If you sell a call option at (i) price, you face two cases by the expiration date: the buyer of your option either

exercises the option or lets it expire. The buyer will exercise the call option only if the call option is (ii) the

money, that is, only if the market price is (iii) than the strike price. If the buyer lets the option expire, your

profit/loss is the price of the option you sold at. If the buyer exercises the call option, you buy shares of stock in

the market at the market price, deliver it to the buyer, and receive the (iv) price. Your net profit/loss is equal to (v)

price + (vi) price - (vii) price.

[4] John sells shares of XYZ stock short at the current market price $69.

(a) Short sale means that you borrow shares of stock from a broker and sell them. The proceeds are kept in your

account. You also have to put up (i)% additional fund in the account, which is called the (ii) requirement.

(i) (iii)

(b) John plans to close his short sale account on February 13. He wants to protect his investment using a call

option. The call option of strike price $70 that expires on February 13 is traded at price $0.5 per share. Will he

buy this call option to protect from a higher price of $71? That is, will he buy the call option if he thinks the price

can rise to $71?

If he does not buy the call option and price rises to $71, his loss is $(i)-$(ii)=$(iii) per share. If he buys the call

option and exercises the option, he buys shares at $(iv) and return them to the broker, incurring $(v) loss per share

from the transaction of shares. Since he paid $(vi) per share for the option, his total loss will be $(vii) per share.

Therefore, his loss is (viii) when he buys and exercises the call option.

1[1] Treasury notes and bonds pay interest every (i) months until they mature. The interest rate on these securities are called the (ii) rate. Maturities of Treasury notes range from (iii) years to (iv) years, and the maturity of a Treasury bond is typically (v) years. To compute the yield to maturity of T-notes or T-bonds, we need to find the interest rate that makes the (vi) value of all coupon and face value be equal to the price of security. TIPS, which stands for Treasury Inflation Protected Securities, are designed to protect investment from the effect of inflation. The coupon rate of TIPS is fixed over time, but the face value is adjusted by the (vii) every (viii) months

[3] Local governments usually issue bonds at a fixed interest rate. But, some local governments issued them at a floating rate and then entered the interest rate swap (IRS) agreement with the banks. To understand how the IRS works, consider two firms, A and B. Firm A wants a floating rate loan because it expects the interest rate will decline while firm B wants a fixed rate loan because it expects a rise in interest rate. The current interest rate they face in the market are as follows.

firm fixed floating

A 5% LIBOR+0.3%

B 6% LIBOR+0.9%

If they borrow what they want, firm A will pay LIBOR+0.3% floating rate and firm B will pay 6% fixed rate.(a) Firm B has to pay a higher interest rate than firm A in either market. But, firm B has a comparative advantage in the (i) interest rate market. Therefore, they agree on an IRS, in which firm B borrows a (ii) rate loan and firm A borrows a (iii) rate loan. Firm A agrees to pay a floating rate LIBOR+0.2% to firm B and firm B pays a fixed rate x% to firm A. We need to determine x that benefits both firms. To do this, we need to figure out the net interest rate each firm pays when they sign on the IRS. Firm A pays (iv) to the lender and pays (v) to firm B, and receives x% from firm B. Therefore, the net interest rate firm A pays is (vi). Similarly, the net rate that firm B has to pay is (vii).

(b) Each firm's net interest rate must be lower than what each firm can borrow their preferred loans. This requires that firm A’s net rate must be lower than (i) and firm B's nest rate must be lower than (ii). These two conditions require that x% must be greater than (iii) and less than (iv). If x% is closer to the lower bound, firm B is better off than firm A. Suppose we choose a fair split by taking the average of the two bounds. Then, x=(v), and the net interest rate for firm A is (vi) and the net interest rate for firm B is (vii). These results show that both firms are better off.

[1] Financial assets are often classified into three major classes which are the fixed income securities, (i) and

derivatives. An example of derivatives is the stock option which is a contract whose value is derived from the

price of underlying stock. Buyers and sellers of options buy from and sell to the OCC which stands for the (ii). A

buyer of put option has the (iii), but no (iv), to (v) specified number of shares of the underlying stock at a (vi)

price by the (vii) date. A put option is in the money if the current market price is (viii) than the strike price.

[2] The IBM stock was traded at $139 per share last Friday. There are call and put options on IBM stock with

strike price $138 that expire on April 5. The bid and ask prices of call option are $3.40 and $3.60 and the bid and

ask prices of put option are $1.87 and $2.00. Assume that there are no other transactions cost. If John bought this

call option, he expects the stock price will (i) at least to $(ii) and more. If Alice bought this put option, she expects

while firm B wants a fixed rate loan because it expects a rise in interest rate. The current interest rate they face in

the market are as follows: Fixed and floating rates for firm A are 4% and LIBOR+0.2% and for firm B are 5% and

LIBOR+0.8%

(a) Firm A and B enter an IRS contract. Firm A borrows a fixed rate loan and firm B borrows a floating rate loan.

Firm A agrees to pay a floating rate LIBOR+0.4% to firm B and firm B pays a fixed rate x% to firm A. We need

[6] (a) Three major stock market indexes are the Dow Jones Industrial Average (DJIA), the S&P 500 composite

index, and the NASDAQ composite index. The DJIA index is a (i) weighted index of (ii) blue chip companies.

The S&P500 index and the NASDAQ index are the (iii) weighted index of 500 large cap companies and all stocks

registered at the NASDAQ market, respectively. Less known index such as S&P500 EWI allocates equal weight

to each of 500 stocks.

(b) You have $24,000 to invest in two stocks: ABC and XYZ. The share prices of ABC and XYZ are $25 and

$75, respectively, and their outstanding shares are 20 million and 4 million, respectively. If you want to track the

DJIA index, the amount you allocate to ABC is computed by $24000*(i)=$(ii) and allocate the remainder $(iii) to

XYZ. If you want track the S&P500 composite index, the amount you allocate to ABC is computed by

$24000*(iv)=$(v) and allocate the remainder $(vi) to XYZ. If you want to track the equally weighted index, you

(b) To explain the indifference curve of a risk averse agent, consider the figure below where P1 represents the risk

and ER of the portfolio that the agent is currently holding.

Can we find a portfolio in quadrant A that can be indifferent to P1? The answer is (i) because any portfolio in that

quadrant has a (ii) expected return and has a (iii) risk than P1. Therefore, the agent prefers (iv). A similar line of

thought indicates that the risk averse agent prefers (v). Can we find a portfolio in quadrant B that can be

indifferent to P1? The answer is (vi) because any portfolio in that quadrant has a (vii) expected return and has a

(viii) risk than P1. Therefore, a portfolio in that quadrant (ix) give the same utility. A similar logic can apply to a

returns of the risk-free asset and risky asset, respectively. Let μp=E(r p) and σ p2=var (r p). Let w be the fraction

of fund to be invested in the risky asset. The investor is concerned only about the expected return μc and the risk

σ c of the complete portfolio in their decision on w. The figure below shows the choice set, i.e., all combinations

of the expected return and risk that an investor faces as she chooses different values of w. This line is called the

[1] Consider the choice set of expected return and risk when two risky assets are available. Let ri, μi, and σ i2 be

the return, expected return and variance of risky asset i, respectively, i=1,2, and let σ 12 and ρ be the covariance

and correlation coefficient between risky assets. . We construct a portfolio by investing w i fraction of fund on

asset i, where w1+w2=1. The curve in the risk and expected return space that represents all pairs of risk and

expected return that are attainable by changing w i is called the portfolio possibility curve (PPC). To compute the

PPC, we need to compute the return, expected return and variance of portfolio which are denoted by r p, μp, and

[1] Consider a single-index model which specifies the excess return of asset i as

Ri=αi+β i Rm+ei

where all notations are as used in the lecture. The index model makes the following assumptions:

(A1) E (e i|Rm )=0

(A2) cov (e i , e j )=0 , i≠ j

Assumption (A1) implies

(A1a) E (e i )=0

(A1b) cov (ei , Rm)=0

Let var ( ei )=σe i

2 .

(a) Assumption (A1) implies the conditional and unconditional means of Ri are as given below:

E ( Ri|Rm )=α i+ βi Rm μi=E (Ri)=α i+ βi μm

Under assumptions (A1) and (A2), derive (i) σ i2, (ii) σ ij, and (iii) σ ℑ. For each case, specify which assumptions

are used. [6 points each. All or None for each]

(i) σ i2=¿

(iii) σ ℑ=¿

Assumption(s) used:

(b) β i is called the "beta" of asset i and it represents the marginal effect of a change in Rm on Ri or on E ( Ri|Rm ). The equation in (i) of question (a) above indicates that, given the market excess return Rm, the expected excess return of asset i is the sum of two components. One component that is attributable to the market condition as a whole is equal to (i), and another component is the (ii) of asset i and it represents the expected excess return of stock i beyond any return induced by market’s excess return. (i) (ii)

(c) The result in question (a) shows two components in the risk of Ri. The risk of asset i attributable to the uncertainty common to the entire market is the term (i) and it is called the (ii) risk, and the risk from the changes in the firm-specific factor is the term (iii) and it is called the (iv) risk. The former is also called the (v) risk and the latter is also called the (vi) risk. The risk that can be removed by diversification is the (vii) risk.

(d) If β i>1, the return of asset i is (i) volatile and it is (ii) than the market as a whole. The converse holds when the beta of asset i is less than 1. The beta of Walmart is expected to be (iii) than 1 and the beta of Bank of America is expected to be (iv) than 1.

(i) (less, more) (ii) (riskier, safer) (iii) (greater, smaller) (iv) (greater, smaller)

[2] Parameters of the single index model are estimated by the ordinary least squares (OLS) method. This method

assumes that alpha and beta stay constant during the sample period. This is usually not true. It has been observed

empirically that betas tend to converge toward the average of betas of all equities, which is 1. This property is

called the (i) property. Merrill Lynch incorporates this property into the computation of beta by taking a weighted

average of estimated historical beta ( β̂) and 1.

Adjusted beta β̂adj = (ii)

An alternative way to take changing beta into account is the method that Blume developed. Blume’s idea is to

find the common trend of betas over time and use the trend to predict the betas in forecasting period. Explain the

steps to follow to execute Blume’s method.

step 1. Select two (non-overlapping) periods, period 1 and period 2.

step 2. Estimate the beta of each stock in each period separately. Let them be denoted by β̂ i 1 and β̂ i 2 for each

stock i=1,2,,n.

step 3. The common time trend between these two sets of estimates is modeled as a linear regression model (iii).

Use notations δ and γ for the coefficients.

step 4. Let the estimates of coefficients be denoted by δ̂ and γ̂, respectively. Compute the forecast of beta in

period 3 using equation (iv).

[5] Consider two firms, A and B. Firm A wants a floating rate loan because it expects the interest rate will decline

while firm B wants a fixed rate loan because it expects a rise in interest rate. The current interest rate they face in

the market are as follows. Firm A can borrow at 5% rate in fixed rate market and at LIBOR+0.2% at floating rate

market. Firm B can borrow at 6% rate in fixed rate market and at LIBOR+1.0% at floating rate market.

(a) Firm B has to pay a higher interest rate than firm A in either market. But, firm B has a comparative advantage

in the (i) interest rate market because firm B has to pay (ii)% higher than firm A in the fixed rate market, while

firm B has to pay (iii)% higher rate than firm A in the floating rate market. Therefore, they agree on an IRS, in

which firm B borrows a (iv) rate loan and firm A borrows a (v) rate loan. Firm A agrees to pay a floating rate

LIBOR+x% to firm B and firm B pays a fixed rate y% to firm A. We need to determine x and y that benefit both

firms. To do this, we need to figure out the net interest rate each firm pays when they sign on the IRS. Firm A

pays (vi) to lender, pays (vii) to B, and receives (viii) from B. A’s net payment is (ix). Similarly, firm B pays (x)

to lender, pays (xi) to A, and receives (xii) from A. B’s net payment is (xiii). For the IRS to benefit both firms, net

payment under IRS must be smaller than the payment to the lender they prefer. This requires for firm A that

(xiv)<(xv), which is simplified to (xvi), and for firm B that (xvii)<(xviii), which is implied to (xix). If they first

agreed on x=0.2, the range of y they can negotiate is from (xx) to (xxi).

[9] Consider the choice set of expected excess return and its risk when two risky assets are available. Let Ri, μi,

and σ i2 be the excess return (Ri=ri−r f), expected excess return and variance of risky asset i, respectively, i=1,2,

and let σ 12 and ρ be the covariance and correlation coefficient between two risky assets. . We construct a portfolio

by investing w i fraction of fund on asset i, where w1+w2=1. (a) To compute the PPC, we need to compute the return, expected return and variance of portfolio which are

denoted by Rp, μp, and σ p2, respectively. It is easy to show Rp=¿(i), μp=¿(ii), and σ p

2 is (iii).

(b) The optimum portfolio P of risky assets on the PPC is found by finding the portfolio that maximizes the (iv) ratio which is equal to (v). Graphically, it is found where the CAL is (vi) to the PPC.(c) The PPC stands for the (vii) and the CAL stands for the (viii).
