• The maturity of the option is 90 days or .25 year;
• The (annualized) variance in the returns of the stock is .16; and
• The risk-free rate of interest is 4 percent.
a. What is the value of this call option?
b. Value the call option where the exercise price is only $25.
c. Value the call option under the original assumptions stated earlier but with an annualized variance in stock returns of .32. Why did the value of the call option increase when compared to part a?
