In 1973, Fischer Black and Myron Scholes developed the Black-Scholes option pricing model (OPM). (1) What assumptions underlie the OPM? (2) Write out the three equations that constitute the model. (3) According to the OPM, what is the value of a call option with the following characteristics? Stock price = 27.00 Strike price = 25.00 Time to expiration = 6 months = 0.5 years Risk-free rate = 6.0% Stock return standard deviation = 0.49
Put–Call Parity The current price of a stock is $33, and the annual risk-free rate is 6%. A call option with a strike price of $32 and with 1 year until expiration has a current value of $6.56. What is the value of a put option written on the stock with the same exercise price and expiration date as the call option?
An institutional investor holds several European call options on a non-dividend-paying stock with a strike of $55. The current stock price is $65, while the continuously compounded risk-free rate is 2% p.a and volatility is 25%. Assuming that the market follows the assumptions of the Black-Scholes option model: (i) Calculate the price of a one-year call option on the stock. (ii) Calculate the price of a one-year put on the same stock with the same strike price.
The price of a European call option on a non-dividend-paying stock with a strike price of $48.25 is $4.75. The stock price is $51.05, the continuously compounded risk-free rate (all maturities) is 6.45% and the time to maturity is 6 months. What is the price of a 6 months European put option on the stock with a strike price of $48.25? Answer with three decimal digits accuracy.
You observe a nine-month European call option with an exercise price of $115 on a stock that is currently trading for $112 selling for $8.35. What is implied volatility on the option if the stock does not pay a dividend and the current risk-free rate is 2%?
Consider a stock priced at $33 with a standard deviation of 0.3. The risk-free rate is 0.05. There are put and call options available at exercise prices of 35 and a time to expiration of six months. The calls are priced at $2.39 and the puts cost $2.05. There are no dividends on the stock and the options are European. Assume that all transactions consist of 100 shares or one contract (100 options). Suppose the investor constructed a covered call. If the transaction is closed out when the option has three months to go and the stock price is at $39, what is the investor's profit?
Suppose that a stock price is currently 56 dollars, and it is known that five months from now, the price will be either 22 percent higher or 22 percent lower. Find the value of a European put option on the stock that expires five months from now, and has a strike price of 55 dollars. Assume that no arbitrage opportunities exist, and a risk-free interest rate of 6 percent.
A collar is established by buying a share of stock for $54, buying a 6-month put option with exercise price $47, and writing a 6-month call option with exercise price $61. On the basis of the volatility of the stock, you calculate that for a strike price of $47 and expiration of 6 months, N(d1) = 0.7298, whereas for the exercise price of $61, N(d1) = 0.6374. Required: What will be the gain or loss on the collar if the stock price increases by $1? What happens to the delta of the portfolio if the stock price becomes very large? What happens to the delta of the portfolio if the stock price becomes very small?
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?
You observe that a non-dividend paying stock currently trades for ₺150 on Borsa Istanbul. The annual standard deviation of its returns is expected to be 41% per year over the next year and the continuously compounded risk-free rate of interest is flat at 18% per year over all investment horizons. Compute the theoretical price of a European call option with a strike price of ₺200 and five months remaining until expiration written on a single share of this stock using to the Black-Scholes option pricing model
Consider an American put option with time to expiry 15 months, and a strike of 74. The current price of the underlying is 71. Divide the time to expiry into three 5-months intervals. Assume that in each 5-months interval, the price can either rise by 5, or fall by 5, with unknown probability. The risk-free (continuously compounding) rate is 0.042. Using a binomial tree, identify the circumstances under which early exercise would be rational for the holder of this option. Draw the binomial tree and show the necessary calculation and briefly explain the answer.
Suppose that a stock price is currently 49 dollars, and it is known that one month from now, the price will be either 8 percent higher or 8 percent lower. Find the value of an American call option on the stock that expires one month from now, and has a strike price of 51 dollars. Assume that no arbitrage opportunities exist, and a risk-free interest rate of 7 percent.
