How would the stock price of each of the following Swiss companies be affected by an unanticipated appreciation in the Swiss franc of 10 percent, only 2 percent of which could be justified by comparing Swiss inflation to that in the rest of the world?

a. Swiss Air: More than two-thirds of its employees are Swiss. Most revenues come from international fares set in U.S. dollars.

b. Nestlé: Fewer than 5 percent of its employees are Swiss. Most revenues are derived from sales of consumer goods in a wide range of countries with competition from local producers.

c. Union Bank of Switzerland: Most employees are Swiss. All non–Swiss franc monetary positions are fully hedged.
