Question
The Black-Scholes option pricing model states:a.The value of an at-the-money call and put is the same.b.The risk-free interest rate has no bearing on the option price.c.The option price is independent of the underlying stock's anticipated return on investment.d.The risk-free interest rate is the most challenging metric to measure.
Solution
The Black-Scholes option pricing model is a mathematical model used to calculate the theoretical price of options. Here are the answers to your statements:
a. False. The Black-Scholes model does not state that the value of an at-the-money call and put is the same. The value of a call and a put option can be different due to factors such as the underlying asset's price, the strike price, the time to expiration, the risk-free interest rate, and the volatility of the underlying asset.
b. False. The risk-free interest rate does have a bearing on the option price. According to the Black-Scholes model, an increase in the risk-free interest rate will increase the price of a call option and decrease the price of a put option.
c. True. The Black-Scholes model assumes that the option price is independent of the underlying stock's anticipated return on investment. This is because the model assumes that the returns on the underlying asset are lognormally distributed and that the return on the asset is constant.
d. False. The risk-free interest rate is not the most challenging metric to measure. In fact, it is usually the volatility of the underlying asset that is the most difficult to estimate in the Black-Scholes model. The risk-free rate can be easily obtained from government securities.
