Suppose a Canadian investor wishes to invest in a British stock currently selling for 40 per share. The investor has $1,600,000 to invest, and the current exchange rate is $1.60/. Consider three possible prices per share at 30, 40 and 50 after 1 year. Also, consider three possible exchange rates at $1.5/, $1.6/ and $1.7/ after 1 year. If each of outcomes in terms of share price and exchange rates are equally likely, calculate the standard deviation of Pound-denominated and dollar denominated rates of return.
