Question

A current price of a stock is $22 and the end of one year its price will be either $27 or $17. The annual risk free rate is 6.0% based on daily compounding. A 1-year call option on the stock with an exercise price of $22 is available. Based on the binominal model, what is the options value?

A. $2.99

B. $2.70

C. 2.43

D. 3.29

E. $3.62

These are the only options give on the practice quiz, and I'm not getting any of these answers. The closest I get is $3.01, and I'm not even sure if that is right. Help!

Explanation / Answer

Value of option today= C1*P+(C2*(1-p)/(1+r)

           Probability(P)=spot price(1+interest rate)-lower price/higher price-lower price

                                 =22(1+.06)-17/27-17

                            P   =.632

                        1-P   =.368

maturity price premium                   value of call on expiry               probability                expected value

27                                                      5                                              .632                          3.16

17                                                       0                                              .368                            0

                                                                                     value as call as on expiry              3.16

value of call option          3.16*1/1.06)

                                     =$2.99

so value of call option is A=$ 2.99

value of option          =
