Questions

Speculаtiоn with currency оptiоns: Cаlаndra Panagakos works for CIBC Currency Funds in Toronto. Calandra is something of a contrarian -- as opposed to most of the forecasts, she believes the Canadian dollar (C$) will appreciate versus the U.S. dollar over the coming 90 days, and is willing to speculate based on her contrarian view. The current spot rate is $0.6750/C$. Calandra may choose between the following options on the Canadian dollar:                                       Option                        Strike Price                Premium Put on C$                   $0.7000                       $0.00003/S$ Call on C$                  $0.7000                       $0.00049/S$          (1a). Should Calandra buy a put option on Canadian dollars or a call option on Canadian dollars?
