Calculate the arithmetic mean and geometric mean historical rates of return on these asset classes across the 15 years period. Calculate the standard deviations, assuming this fifteen year period to be a sample drawn from a single underlying population of possible outcomes. Comment on your results. > b). Calculate the correlation matrix for the above data set. Comment on the asset class correlations you have identified, from the perspective of the risk reducing effects of diversification across asset classes. c). Calculate the covariance matrix and the border-multiplied covariance matrix for an equally weighted portfolio. Identify the arithmetic mean returrn
