Consider the same situation with 4 assets and the following expected rates of return and variance-covariance matrix: 0.1784 0.093857 -0.000233 0.000195 -0.000094 m= 0.0234 V= -0.000233 0.051747 -0.000149 0.000081 0.1320 0.000195 -0.000149 0.056614 -0.000052 0.1375 -0.000094 0.000081 -0.000052 0.060000 1) Find the weights of a portfolio that achieves an expected rate of return of 10% with the lowest possible variance (or standard deviation). 2) Show that using the weights obtained you do indeed have a portfolio expected return of 10% (i.e., verify the result you just obtained) 3) Compute the resulting portfolio's standard deviation. How does this optimal portfolio compare against asset # 2 ?
