正确的应该是borrow369.17?

NO.PZ2023041003000034

问题如下:

Messer explains, “Of course, with the index moving down 10% in the last twelve months, the payoffs with these options could have been replicated without using options.” Szillat responds, “My understanding is that the payoff would have been the same as the call option if you had purchased 0.5697 index units and lent EUR 356.79 at the 1-year interest rate.”

With respect to his assessment of replicating the option payoff, Szillat is least likely correct about:

选项:

A.

lending EUR 356.79.

B.

using the one-year interest rate.

C.

purchasing 0.5697 index units.

解释:

Szillat is incorrect in his method of replicating the call option. It can be replicated by purchasing the amount of the underlying shares designated by the hedge ratio and then borrowing (not lending) an amount equal to the present value of ((hedge ratio × S–) + c–).

嗨,从没放弃的小努力你好:


正确的做法应该是borrow PV(h × S- + c-) = (0.5697 * 648 + 0) / 1.03 = 358.41
