there is no correlation given, i believe they want us to do "(variance_1*0.5 + variance_2*0.5) = variance between two stocks" but I am not sure.

Given Stock 1 Stock 2 Variance_1 = 5.42% Standard Deviation_1 = 23.28% Variance_2 = 8.62% Standard Deviation_2 = 29.36% a) Annualize the variance by multiplying by 12. Annualize the standard deviation by multiplying by the square root of 12 b) Calculate the annualized variance and standard deviation for a portfolio that each month has equal holdings in the two stocks. Is the result more or less than the average of standard deviations of the two stocks? Why?
