Question
You are given the following information about a securities market: (i) There are two nondividend-paying stocks, X and Y. (ii) The current prices for X
You are given the following information about a securities market:
(i) There are two nondividend-paying stocks, X and Y.
(ii) The current prices for X and Y are both $100.
(iii) The continuously compounded risk-free interest rate is 10%.
(iv) There are three possible outcomes for the prices of X and Y one year from now:
Outcome | X | Y |
1 | $200 | $0 |
2 | $50 | $0 |
3 | $200 | $300 |
Let C_X be the price of a European call option on X, and P_Y be the price of a European put option on Y. Both options expire in one year and have a strike price of $95. Calculate P_Y - C_X
NOTES: This is a problem almost identical to a problem from the MFE Fall 2008 exam, but a value (Outcome 3 X Price) has been changed. Also, we have not used any linear algebra (directly) in this class so I need to be able to demonstrate work that doesn't utilize linear algebra, if that's possible.
