Assume that a stock trading for $32 today will be worth either $25 or $35 in two years. A risk-free asset offers an annualized 3% return (continuously compounded) over that time period. What is the hedge ratio (delta) of a two-year put option on this stock with a strike price of $28? O a. -0.6 O b. 0.7 ○ c. 0.5 d. 0.6 O e. -0.7

A risk-free asset offers an annualized 3% return (continuously compounded) over that time period. • What is the price today of a two-year put option on this stock with a strike price of $32? The maximum error is 0.1. O a. 1.52 O b. 2.47 O c. 1.82 O d. None of these answers O e. 2.07

Suppose the 1-year futures price on a stock-index portfolio is 1,914, the stock index currently is 1,900, the 1-year risk-free interest rate is 3%, and the year-end dividend that will be paid on a $1,900 investment in the market index portfolio is $40.a. By how much is the contract mispriced?b. Formulate a zero-net-investment arbitrage portfolio and show that you can lock in riskless profits equal to the futures mispricing.c. Now assume (as is true for small investors) that if you short sell the stocks in the market index, the proceeds of the short sale are kept with the broker, and you do not receive any interest income on the funds. Is there still an arbitrage opportunity (assuming that you don’t already own the shares in the index)? Explain.d. Given the short-sale rules, what is the no-arbitrage band for the stock-futures price relation-ship? That is, given a stock index of 1,900, how high and how low can the futures price be without giving rise to arbitrage opportunities?

A European call that will expire in one year is currently trading for $3. Assume the risk-free rate (based on continuous compounding) is 5%, the underlying stock price is $60 and the strike price is $55. a. Is there an arbitrage opportunity? b. Describe exactly what a trader should do to take advantage of the arbitrage opportunity assuming it exists. c. Determine the present value of the profit that the trader can earn assuming you identify an arbitrage opportunity. Use at least four decimal places for those questions that require a numerical answer.
