Consider the following information on a portfolio of three stocks: Note: Don't forget to click the button for HINT for a video as it shows the formulas to complete this problem. This question is mostly like an earlier Excel-based problem you did earlier. The one added element is you must calculate the risk premium in question b, which is the expected return - risk-free rate. The risk-free rate is assumed to be the T-bill rate. State of Probability of Economy State of Economy Stock A Rate of Return Boom Normal Bust .15 .54 .31 .08 .16 .17 Stock B Rate of Return .33 .28 -.27 Stock C Rate of Return .44 .26 -.36 a. If your portfolio is invested 38 percent each in A and B and 24 percent in C, what is the portfolio's expected return, the variance, and the standard deviation? Note: Do not round intermediate calculations. Round your variance answer to 5 decimal places, e.g., .16161. Enter your other answers as a percent rounded to 2 decimal places, e.g., 32.16. b. If the expected T-bill rate is 4.55 percent, what is the expected risk premium on the portfolio? Note: Do not round intermediate calculations and enter your answer as a percent rounded to 2 decimal places, e.g., 32.16.
