1. Consider the following bond: annual coupon 5%, maturity 5 years, annual compounding frequency.

i. What is its relative price change if its required yield increases from 10% to 11%?

ii. What is its relative price change if its required yield increases from 5% to 6%?

iii. What conclusion can you draw from these examples? Explain why.

2. The Pamodzi Dairy Company has just come up with a new lactose-free dessert product for people who can't eat or drink ordinary dairy products. Management expects the new product to fuel sales growth at 30% for about two years.

After that competitors will copy the idea and produce similar products, and growth will return to about 3%, which is normal for the dairy industry in the area.

5. Suppose a stock currently trades at a price of K150. The stock price can go up 33 percent or down 15 percent. The risk-free rate is 4.5 percent.

i. Use a one-period binomial model to calculate the price of a put option with exercise price of K150.

ii. Suppose the put price is currently K14. Show how to execute an arbitrage transaction that will earn more than the risk-free rate. Use 10,000 put options.

iii. Suppose the put price is currently K11. Show how to execute an arbitrage transaction that will earn more than the risk-free rate. Use 10,000 put options.

6. With particular reference to the local market, identify and explain six constraints to portfolio revision process.

7. Use the Black-Scholes-Merton model to calculate the prices of European call and put options on an asset priced at K68.5. The exercise price is K65, the continuously compounded risk-free rate is 4 percent, the options expire in 110 days, and the volatility is 0.38. There are no cash flows on the underlying.
