[Forward price for delivery date T]=S(t)exp((rq)(Tt)) In this example ... is the forward price for delivery in 6 months higher or lower than the current price of $50? [B] Recall the put-call parity relationship: [PRICE OF K-STRIKE CALL (EXPIRY T)] - [PRICE OF K-STRIKE PUT (EXPIRY T)] = [VALUE OF FORWARD CONTRACT WITH INVOICE PRICE K (DELIVERY DATE T)] Look at the table. At what strike do the put and the call have the same value? Is this consistent with put-call parity? [C] Revisit the put-call parity relationship: CK(S,t)PK(S,t)=VK(S,t) where the subscript " K " means strike =K (for the two options C and P ) and invoice price =K (for the forward contract V). Assume that the dividend rate is zero (like we have here). Take the derivative with respect to the current stock price S of the put-call parity relationship. Show that: ( DELTA of CALL) ( DELTA of PUT )=1
