The returns of Company A for the past six months are 12%, 11%,
16%, 8%, 13%, and 14%. Calculate the standard deviation of this
company’s return.
In your portfolio you have invested 30% and 70% in Stock X and
Stock Z, respectively. The standard deviation of X is 12%. The
standard deviation of Z is 9%. The correlation between X and Z is
0.50. Calculate the portfolio standard deviation.
For the same problem before, now calculate the portfolio
standard deviation...
