1. Assume a particular stock has an annual standard deviation of 55 percent. What is the standard deviation for a 2-month period? (Round your answer to 2 decimal place. Omit the "%" sign in your response.)

Explanation / Answer

1.Monthly standard deviation=Annual standard deviation/Square root of 12 months

=55%/Square root of 12 months

=15.88

=(12.5-6.2)/1.45
