A put with 1-year to maturity is written on a stock. The current underlying stock price is $20. The option’s exercise price is $18, the interest rate is 3.74%, and the stock’s volatility is 32.7%. The price of a call written on the same stock with the same exercise price and time to maturity is $4.3. Use BSM pricing to determine if put-call parity holds.

Assume that the value of a call option using the Black-Scholes model is $8.94. The interest rate is 8 percent, and the time to maturity is 90 days. The price of the underlying stock is $47.38, and the exercise price is $45. Calculate the price of a put using the put-call parity relationship.

Data: S0 = 120; X = 126; 1+r = 1.05. The two possibilities for ST are 150 and 102. (Round to 2 decimal places). The range of S is 48 while that of C is 24 across the two states. What is the hedge ratio of the call? Hedge ratio ? Calculate the value of a call option on the stock with an exercise price of 126. (Do not use continuous compounding to calculate the present value of X in this example because we are using a two-state model here; the assumed 5% interest rate is an effective rate per period.) Call value ?
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?
Suppose that a call option with a strike price of $48 expires in one year and has a current market price of $5.17. The market price of the underlying stock is $46.25, and the risk-free rate is 1%. Use put-call parity to calculate the price of a put option on the same underlying stock with a strike of $48 and an expiration of one year. The price of a put option on the same underlying stock with a strike of $48 and an expiration of one year is $. (Round to the nearest cent.)

Q.20 The risk manager of a large investment bank is reviewing the bank's investments in options contracts. He is particularly interested in call options contracts on shares of Hamilton Invest that the bank bought a few months ago. Hamilton Invest just unexpectedly announced that they would pay a USD 3 dividend per share in the sixth and twelfth months. The risk manager is concerned with the impact of dividends on the option's price. The risk- free rate is 5%, and the option has the following characteristics: A By how much will the price of the options change after the announcement of the dividends? Assume that N(d,) before and after the announcement of the dividend is 0.7654 and N(d₂) before and after the announcement of the dividend is 0.5489? B Strike price Expiration Underlying's Price Annual volatility The price of the option will increase by USD 3.32 USD 140 13 months USD 151 35% The price of the option will decrease by USD 3.32
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 .
Use the Black-Scholes formula to find the value of a call option based on the following inputs. Note: Do not round intermediate calculations. Round your final answer to 2 decimal places. Stock price Exercise price Interest rate Dividend yield Time to expiration Standard deviation of stock's returns Call value $ 51 $ 64 0.068 0.04 0.50 0.265
