How does the value of an asset (valued in two different currencies) change when the exchange rate changes?
Gold is traded on the London stock exchange (LSE) and the New York stock exchange (NYSE) under various separate asset tickers, mainly denominated in sterling and US dollars respectively.  These stocks will reflect FX changes very quickly.  If you sold LSE gold and foreign exchanged your sterling to dollars to buy NYSE gold you would almost certainly lose on the spreads upon selling, FX'ing and re-buying. In short, the same asset doesn't exist in multiple currencies.  It may have the same International Securities Identification Number (ISIN), but it can trade with different Stock Exchange Daily Official List (SEDOL) identifiers, reflecting different currencies and/or exchanges, each carrying a different price at any one time.
