Schweser Book 5. SS17/Q5/Page 109

Question asks to calculate contribution of currency risk, which is relatively easy enough : = sd of portfolio (us) - sd of foreign stock(fc) The confusion is within the Schweser answer: it states that the contribution of currency risk measures the risk incremental to foreign asset rick AFTER considering currency risk, and is the difference between asset risk in domestic currency terms minus the risk of the foreign asset in foreign currency terms: Is there a difference between contribution of currency risk and currency risk? Thanks,
