What is the standard deviation of the portfolio that is 50% in

please this part of the question ASAP too  What is the standard deviation of the rate of return on your client's portfolio? (Round your intermediate calculations and final answer to 1 decimal place.)

Assume that the following data available for the portfolio, calculate the expected return, variance and standard deviation of the portfolio given stock A accounts for 45% and stock B accounts for 55% of your portfolio? (4 marks) A B Expected return 12.5% 18.5% Standard Deviation of return 15% 20% Correlation of coefficient (p) 0.4

Consider the following information on a portfolio of three stocks: State of Economy Probability of State of Economy Stock A Rate of Return Stock B Rate of Return Stock C Rate of Return Boom.13.02.32.50 Normal.55.10.22.20 Bust .32.16.21.35 If your portfolio is invested 40 percent each in A and B and 20 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. If the expected T-bill rate is 4.25 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.

Suppose Asset A has an expected return of 10 percent and a standard deviation of 10 percent. Asset B has an expected return of 20 percent and a standard deviation of 20 percent. If the correlation between A and B is (- 1), what are the expected return and standard deviation for a portfolio comprised of 40 percent Asset A and 60 percent Asset B?

You are given the following information concerning three portfolios, the market portfolio, and the risk-free asset: Portfolio Rp op Bp X 14.0% 31% 1.35 Y 13.0 26 1.10 Z 7.0 14 .75 Market 10.2 19 1.00 Risk-free 6.0 0 0 What are the Sharpe ratio, Treynor ratio, and Jensen's alpha for each portfolio? (A negative value should be indicated by a minus sign. Leave no cells blank - be certain to enter "0" wherever required. Do not round intermediate calculations. Round your ratio answers to 5 decimal places. Enter your alpha answers as a percent rounded to 2 decimal places.) Sharpe Ratio Treynor Ratio Jensen's Alpha Portfolio X % Y % Z % Market %
