Consider a portfolio of 5 assets, where each asset in the portfolio is equally weighted at 1/5. The variance of each asset's return is given by v=0.32. The covariance of any two asset returns is given by c=0.02. Suppose you want to increase the number of assets in order to halve the variance on the portfolio. Assuming the new set of assets have the same variance and covariance, and the weights on each asset are given by 1/N, how many assets N are in the new portfolio? (Hint: refer to notes on Nave diversification) (a) N=10 (b) N=15 (c) N=20 (d) N=25 (e) N=30
