Assume that an investor holds the following portfolio: short stock bought at a price 90$, long one 3-month maturity call option on the same stock with an exercise price of $88.a) Show the payoff structure of this portfolio at option expiration both numerically and graphically.b) Calculate the profit/loss on this position if stocks are selling at $80 on the option maturity date.Calculate the profit/loss on the position if the stocks are selling at $110. Call option premium is $5,while put option premium is $3. Ignore the transaction costs.c) Explain what kind of "bet" the investor is making. What must the investor in such a portfolio believeabout the stock price to justify this position?

Suppose a stock is currently (time t = 0) worth 100. Further, suppose the one year annually compounded interest rate is 2%, and the two year annually compounded rate is 3%. Find the following:a) The forward price for a forward contract on the stock with maturity year T1 = 1. b) The forward price for a forward contract on the stock with maturity year T2 = 2.c) The forward price for a forward contract with maturity T1 = 1 on a ZCB with maturity T2 = 2.d) The forward price for a forward contract with maturity T1 = 1 on a forward contract on the stock with maturity T2 = 2 and delivery price K = 101.
Consider shorting a call option c on a stock S where S = 24 is the value of the stock, K = 30 is the strike price, T = ½ is the expiration date, r = 0.04 is the continuously compounded interest rate per year, and  = 0.3 is the volatility of the price of the stock. Determine the delta ratio Δ .
Consider the three stocks in the following table. Pt represents price at time t, Qt represents shares outstanding at time t. Stock C splits two for one in the second period from t=1 to t=2. Calculate the rate of return on a price-weighted index consisting of the three stocks for the first period from t=0 to t=1. Answer in percentage. Answer options: 0.00% 2.49% 6.06% 8.95% 1.30%
Suppose that a June call option to buy a share for $65 costs $3.5 and is held until June. Under what circumstances will the holder of the option make profit Under what circumstances will the option be exercised? Draw a diagram showing how the profit on a long position in the option depends on the stock price at the maturity of the option.

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?
given a stock with a current price of 85.50, exercise price of 83.75, put price of 2.60, call price of 4.52, risk ree rate of 0.025, and days in a year of 365, what is the expiration date of the stock?
A stock sells for $125. A call option on the stock has an exercise price of $110 and expires in 3 months. If the interest rate is 0.15 and the standard deviation of the stock’s return is 0.30. What would be the price of a put option on the same stock with an exercise price of $140 and the same time (3 months) until expiration? Show all workings. (See Appendix for the Cumulative Normal Distribution Table) b) Let the spot rate be Yen 100 / $ and the 3-month forward rate be Yen 99/$. Compute the interest rate differential between the U.S. and Japan at which interest rate parity will hold true.
A stock has a price of $73, which can later be $77 or $69 with equal probabilities. The options with exercise price $77 are valued at $1.53 for the call and $1.73 for the put. a. Calculate the gains/losses/returns for the stock. b. Calculate the gain/losses/returns for a covered call and protective put portfolio.
Consider a stock with a current price of P = $27.Suppose that over the next 6 months the stockprice will either go up by a factor of 1.41 or downby a factor of 0.71. Consider a call option on thestock with a strike price of $25 that expires in6 months. The risk-free rate is 6%.(1) Using the binomial model, what are the endingvalues of the stock price? What are the payoffsof the call option?
