Answer the following questions given the information provide to you Show work on all calculations 15. Suppose you creatod a 2-stock portfolio by investing $0,000 in high tech and $50,000 in collections: 1. Calculate the expectod return (fp), standard deviation (p), and the coefficient of variation (CV/) for this portfolio and fill in the blanks. Expected retum is weighted average, =0.5(9.9%)+0.5(1.2%)=5.5% ii How does the riskiness of this two-stock portfolio compare to the riskiness of the indrvidual stocks if they were held in isolation? 16. Suppose an investor starts with a portfolio consisting of one randomly selected stock. This investor then adds more randomly sclocted stocks her portfolio: i. What happens to the riskiness and to the expectod refurn of her portfolio as mord randomily selected atocks are added to her portfolio? 11. Draw a graph of portfolio risk (i.e, ) on the vertical axis verses the number of randomly selected securities added to a portfolio on the horizontal axis. iit.
