d**m 发帖数: 1 | 1 現在有個call option, 它的payoff是max(0, V1-V2).V1,V2分別為兩個不同stock的價
格。在這種情況下,如果要用black-scholes model, assumuptions 要作哪些改變?謝

of one BM and convert that problem to V2*max(0,V1/V2-1), where V1/V2 follow
one dimensional BM. That is a standard B-S problem. You need to consider
correlation between V1 and V2 to get the correct BM of V1/V2.

numeraire.
