Tevaluate two exchange rates on Yahoo Finance; the CADCHF and the USDCHF. Please click on the camera and take a snapshot of your graph and save the image. Your graph will show you that between the time period of 2012 and 2013 both currency pairs were trading very close to parity (meaning 1-to-1). One currency pair continued to trade at parity after 2013 while the other did not. Please explain what parity implies economically and why the CHF has been able to maintain this parity in relation to the USD but not against the CAD. Use at least 200 words to explain this phenomenon.
