5. 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 the field of finance. Just like stand-alone assets and securities, portfollos are also exposed to risk. Portfolio risk refers to the possibility that an investment portfolio will not generate the investor's expected rate of return. Analyzing portfollo risk and return involves the understanding of expected returns from a portfolio. Consider the following case: Andre is an amateur investor who holds a small portfolio consisting of only four stocks. The stock holdings in his portfollo are shown in the following table: What is the expected return on Andre's stock portfolio? 14.55% 7.28% 13.10% 0.70% Andre 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: What is the expected return on Andre's stock portfolio? 14.55% 7.28% 13.10% 9.7045 Suppose each stock in Andre's portfolio has a correlation coefficient of 0.4(=0.4) with each of the other stocks. If the weighted average of the risk of the individuat securities (as measured by their standard deviations) included in the partially diversified fourstock portfolio is 36%, the portfolio's standart deviation (p) most likely is 36%
