1. The price of gold is currently $600 per ounce. The forward price for delivery in 1 year is $800. An arbitrageur can borrow money at 10% per annum. What should the arbitrageur do? Assume that the cost of storing gold is zero and that gold provides no income.
2. On September 12, 2006, an investor owns 100 Intel shares. As indicated in the table below, the share price is $19.56 and January put option with a strike price of
$17.50 costs $0.475. The investor is comparing two alternatives to limit downside risk. The first is to buy 1 January put option contract with a strike price of $17.50.
The second involves instructing a broker to sell the 100 shares as soon as Intel’s price reaches $17.50. Discuss the advantages and disadvantages of the two strategies. Strike Price
