Bouderi’s portfolio was hedged with a 50 percent hedge ratio. Examining just his U.S. equity exposure of A$285,000, suppose he sold U.S. dollars forward at A$:US$ = 0.56 forward rate. Over his portfolio performance measurement period, the exchange rate moved to A$:US$ = 0.50. What would the currency hedge have contributed in negative performance to the un-hedged U.S. equity portfolio return?
