```QUIZ 3:
1. You have \$ 100 to invest. You can invest it in one of two alternatives. The first is to invest it in a
stock that is trading for \$100. The second is to buy three-month 100- strike calls on the stock
that are currently trading at \$4 each. You expect the stock price to appreciate with a maximum
price after three months of \$110. What is the maximum return on investment you can

of \$975 per OZ, a short position in a European put option on gold with a strike of \$975 per oz,
and a short forward position in gold with a delivery price of \$1,000 per oz. All three contracts
expire in one month. The value of your position is

QUIZ 4:
1. The delta of an option measures, approximately,
The dollar change in option value for a \$1 change in the price of the Underlying
2. The delta of a call option is 0.6. The current price of the call is \$5, and the stock is at \$100.
What is the approximate price of the call if the stock price increases to \$100.50?
\$5.30
5 + 0.6(0.5) – 5.30
3. The delta of a call option is 0.6 The current price of the call is \$5 and that of a put at the same
strike is \$ 4, and the stock is at \$100. What is the approximate price of the put if the stock
price increases to \$100.50?
\$3.80
0.6 – 1 = -0.4

11. A stock is currently trading at SO = 25.85. It is not expected to pay dividends over
the next year. You price a six-month call option on the stock with a strike of K = 15 using the
Black-Scholes model and find the following numbers:
d1 = 2.115d2 = 1.832
N(d1) = 0.983N(d2) = 0.967
Given this information, the delta of the call is
0.983 (N)d1
12. A stock is currently trading at SO = 25.85. It is not expected to pay dividends over the next
year. You price a six-month call option on the stock with a strike of K = 15 using the BlackScholes model and find the following numbers:
d1 = 2.115d2 = 1.832
N(d1) = 0.983N(d2) = 0.967
Given this information, the delta of the call is
-0.237
13. A stock is currently trading at So = 21.30. It is not expected to pay dividends over the next year.
You price a one-month put option on the stock with a strike of K = 22.50 using the BlackScholes model and find the following numbers:

QUIZ 5:
1. Firm A can borrow at 5 % fixed or at Libor+100 bps in the fixed and floating rate markets,
respectively. Firm B can borrow at % fixed or Libor + 200 bps in the fixed and floating rate
markets, respectively. A want to borrow floating and B wants to borrow fixed. If A borrows
fixed and B borrows floating, and they enter into a fixed-for-Libor interest-rate swap in which
A pays Libor flat, what is the range of fixed rates for B that enables at least one firm or both
firms to improve its financing costs (compared to accessing financing in the market directly)?
5% - 7%
2. You enter into a \$100 million notional swap to pay six-month Libor and receive 7 %. Payment
dates are semi-annual on both legs. The last payment date was March 25 and the next
payment date is September 25. Floating payments are based on the USD money-market
convention, and fixed payments are based on the 30/360convention. If the floating rate was
reset to 6 % on March 25, what is the net amount you will receive on September 25? (March
25-September 25 is 184 days)
433, 333
184/360*0.06*100,000,000 = 30666666.67
184/360*0.07*100,000,000 = 35777777.78
