143. Assume that your uncle holds just one stock, East Coast Bank (ECB),
which he thinks has very little risk. You agree that the stock is
relatively safe, but you want to demonstrate that his risk would be
even lower if he were more diversified. You obtain the following
returns data for West Coast Bank (WCB). Both banks have had less
variability than most other stocks over the past 5 years. Measured by
the standard deviation of returns, by how much would your uncle's risk
have been reduced if he had held a portfolio consisting of 60% in ECB
and the remainder in WCB? (Hint: Use the sample standard deviation
formula.)
