Answer:
c. 10.05
less than 39%
Explanation:
an expected return is defined as the profit or loss an investor may earn based on the given rates of return.
to calculate the expected rate of return, we multiply each of the stock's weight by its expected return value. Thus we have;
0.06×0.2 + 0.3×0.14 + 0.35×0.12 + 0.15×0.03 = 0.012+0.042+0.042+0.0045
= 0.1005
multiply the above result by 100% we have 10.05
since the correlation coefficient is 0.4 which is less than 1, then the correlation is not perfectly distributed thus the standard deviation is most likely to be less than 39%.
