We showed in the text that the value of a call option increases with the volatility of the stock. Is this also true of put option values? Use the put-call parity theorem as well as a numerical example to prove your answer.
Describe two conditions which will determine whether or not a stock is in equilibrium. Can either of these conditions show the stock is in equilibrium? Please use a numerical example to describe your response.
Both call and put options are affected by the following five factors: the exercise price, the underlying stock price, the time to expiration, the stock’s standard deviation, and the risk-free rate. However, the direction of the effects on call and put options could be different.
Use the following table to identify whether each statement describes put options or call options.
Statement
Put Option
Call Option
1. When the exercise price increases, option prices increase.
2. An option is more valuable the longer the maturity.
3. The effect of the time to maturity on the option prices is indeterminate.
4. As the risk-free rate increases, the value of the option increases.
