The price of Chive Corp. stock will be either $70 or $90 at the end of the year. Call options are available with one year to expiration. T-bills currently yield 6 percent. |
Suppose the current price of the company's stock is $75. What is the value of the call option if the exercise price is $65 per share? Suppose the exercise price is $85 in requirement 1. What is the value of the call option now? |
Answer | ||||
CMP as on expiry | Probablity | Expected CMP as on Expiry | ||
90 | p | 90p | ||
70 | 1-p | 70(1-p) | ||
Therfore | 1 | 90p+70(1-p) | ||
Therefore CMP as on Today= | 90p+70(1-p) | |||
(1+0.06) | ||||
75= | 90p+70(1-p) | |||
(1+0.06) | ||||
75(1+0.06)= | 90p+70-70p | |||
75*1.06= | 20p+70 | |||
79.5-70= | 20p | |||
9.5= | 20p | |||
p= | 9.5/20 | |||
p= | 0.475 | |||
Therefore | 1-p= | 1-0.475 | ||
1-p= | 0.525 | |||
CMP as on expiry | exercise price | Fair value of call | Probablity | Expected Fair OP |
90 | 65 | 25 | 0.475 | 11.875 |
70 | 65 | 5 | 0.525 | 2.625 |
= | 14.5 | |||
Expected Fair OP as on Today= | 14.5 | = | 13.68 | |
1.06 | ||||
IF CMP as on Expiry= | 85 | |||
CMP as on expiry | exercise price | Fair value of call | Probablity | Expected Fair OP |
90 | 85 | 5 | 0.475 | 2.375 |
70 | 85 | 0 | 0.525 | 0 |
= | 2.375 | |||
Expected Fair OP as on Today= | 2.375 | = | 2.24 | |
1.06 | ||||
