8. [10] You have been hired as a portfolio manager for a fancy hedge-fund. Your first job is to invest $100,000 in a portfolio of two assets. The first asset is a safe asset with a certain return of 4%. The second asset is shares of a dying video-game store that has become popular with retail investors, it has a 26% expected rate of return, but the standard deviation of this return is 10%. Your manager wants a portfolio with as high a rate of return as possible while keeping the standard deviation at or below 4%. How much of the fund's money do you invest in the safe asset?
