I will go through some proofs in details so you can better understand the materials. 2 Homework Review 27.15 Suppose that S is the security price and is the expected return from the security. Then dS S = dt + 1 dz 1 + 2 dz 2 where dz 1 and dz 2 are Wiener processes, 1 dz 1 is the component of the risk in the return attributable to the price of copper and 2 dz 2 is the component of the risk in the return attributable to the yen-dollar exchange rate. If the price of copper is held fixed, dz 1 = 0 and: dS S = dt + 2 dz 2 . Hence 2 is 8% per annum or 0 . 08. If the yen-dollar exchange rate is held fixed, dz 2 = 0 and: dS S = dt + 1 dz 1 . Hence 1 is 12% per annum or 0 . 12....
