7. Portfolio expected return and risk 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 finance. Just like standalone assets and securities, portfolios are also exposed to risk. Portfolio risk refers to the possibility that an investment portfolio will not generate the expected rate of return. Analyzing portfolio risk and return involves the understanding of expected returns from a portfolio Consider the following case: Jacques is an amateur investor who holds a small portfolio consisting of only four stocks. The stock holdings in his portfolio are shown in the following table: Stock Percentage of Portfolio 20% Artemis Inc. Expected Return 8.00% Standard Deviation 28.00% Babish & Co. 30% 14.00% 32.00% 35% 13.00% 35.00% Cornell Industries Danforth Motors 15% 3.00% 37.00% The expected return on Jacques's stock portfolio is Suppose each stock in the preceding portfolio has a correlation coefficient of 0.4 (p = 0.4) with each of the other stocks. The market's average standard deviation is around 20%, and the weighted average of the risk of the individual securities in the partially diversified portfolio of four stocks in 33% If 40 additional, randomly selected stocks with a correlation coefficient of 0.3 with the other stocks in the portfolio were added to the portfolio, what effect would this have on the portfolio's standard deviation (p)? Consider the following case: Jacques is an amateur investor who holds a small portfolio consisting of only four stocks. The stock holdings in his portfolio are shown in the follow table: Percentage of Portfolio Stock Artemis Inc. Expected Return Standard Deviation 20% 8.00% 28.00% Babish & Co. 30% 14.00% 32.00% 35% Cornell Industries Danforth Motors 13.00% 35.00% 15% 3.00% 37.00% The expected return on Jacques's stock portfolio is Suppose each stock in the preceding portfolio has a correlation coefficient of 0.4 (p = 0.4) with each of the other stocks. The market's average standard deviation is around 20%, and the weighted average of the risk of the individual securities in the partially diversified portfolio of four stocks 33%. If 40 additional, randomly selected stocks with a correlation coefficient of 0.3 with the other stocks in the portfolio were added to the portfolio, what effect would this have on the portfolio's standard deviation (ap)? It would gradually settle at about 20%. O It would gradually settle at about 35%. It would stay constant at 33%. It would decrease gradually, settling at about 0%.
