It has an expected return of 10.0% and a Session Corporation at $30 a share to your portfolio. beta of 1.10. You want to add 500 shares of Tundra9 Tundra has an expected return of 14.0% and a beta of 1.30. The total value of your current portfolio is $50,000. a.

Since the total percentages invested in the assets must add up to 1, (1-w A) is 12 the percent of the portfolio invested in asset B. 13 14 The expected return on the portfolio is the weighted average of the expected returns 15 on asset A and asset B. 16 17 18 ^ ^ ^ 19 20 r p w A r A (1 w A ) r B 21 22 23 24 The standard deviation of the portfolio, p, is not a weighted average.

(We converted these from monthly figures to annual figures. Notice that you must multiply the monthly standard deviation by the square root of 12, and not 12, to convert it to an annual basis.) These are shown in the rows above. We also use the CORREL function to find the correlation of the market with the other assets. Using the function Wizard for SLOPE, we found the slope of the regression line, which is the beta coefficient. We also use the function Wizard and the RSQ function to find the R-Squared of the regression. Using the Chart Wizard, we plotted the GE returns on the y-axis and the market returns on the x-axis. We also used the menu Chart > Options to add a trend line, and to display the regression equation and R2 on the chart. The chart is shown below. We also used the regression feature to get more detailed data. These results are also shown below.

However, CAPM actually states that we should regress the excess stock returns (the stock return minus the short-term risk free rate) against the excess market returns (the market return minus the short-term risk free rate). We show the graph for such a regression below. Notice that it is virtually identical to the market model regression we used earlier for GE. Since it usually doesn't change the results whether we use the market model to estimate beta instead of the CAPM model, we usually use the market model.
