7. Portfolio expected return and risk Aa Aa A collection of financial assets and securities is referred to as a portfolio. Most individuals and institutions invest in a portfolio, making portfolio risk analysis an integral part of the field of finance.

The stock holdings in his portfolio are shown in the following table Percentage of Expected Standard Stock Portfolio Deviation Return Artemis Inc 20% 8.00% 32.00% 14.00% Babish & Co 30% 36.00% 39.00% Cornell Industries 35% 13.00% Danforth Motors 41.00% 15% 3.00% What is the expected return on Andre's stock portfolio? 10.80% O 8.10% O 16.20% O 14.58% Suppose each stock in Andre's portfolio has a correlation coefficient of 0.40 (p 0.40) with each of the other stocks The market's average standard deviation is approximately 20%, and the weighted average of the risk of the individual securities in the partially diversified four-stock portfolio is 37% If 40 additional, randomly selected stocks with a correlation coefficient of 0.30 with the other stocks in the portfolio were added to the portfolio, what effect would this have on the portfolio's standard deviation (op)? O It would gradually settle at approximately 50%. O It would gradually settle at about 35% O It would stay constant at 37% O It would gradually settle at approximately 2
