Use any 5 of the 6 risky assets (i.e. stock market indices). They are all measured in US Dollars. Use data only up to the end of February 2019 and calculate the weights of the market (i.e. optimum) portfolio and the weights in the minimum variance portfolio. Plot the efficient frontier. Suppose at the end of February 2019 you invest $1,000 into the (i.) market portfolio, (ii.) the minimum variance portfolio and an (iii.) equally weighted portfolio. What would be the value of your investment 5 years later at the end of February 2024? Comment on all your results. Discuss, generally, whether you would recommend investing in a portfolio whose weights have been calculated through optimization based on historic data.
