Given the following probability distribution, what are the expected return and the standard deviation of returns for Security J? State Pi ri 1 0.5 11% 2 0.3 8% 3 0.2 5% O 9.40%; 2.04% O 8.90%; 2.34% O 7.40%; 2.94% O 8.40%; 2.64% O 7.90%; 1.74%

Is the portfolio risk the weighted average of the variance or covariance?

Suppose that there are four risky assets whose expected returns E(r) and variance- covariance matrix (S) are shown in the spreadsheet below. We also consider the portfolio weights of two portfolios x and y of risky assets (see Cells B8:E9): 1 8 Portfolio x 9 Portfolio y A FOUR-ASSET PORTFOLIO PROBLEM Variance-covariance, S 20 Portfolio variance, 21 Portfollo standard deviation o 0.10 0.01 0.03 0.05 11 Portfolio x and y statistics: Mean, variance, covariance, correlation 12 Mean, Ejr, 13 Variance, 14 Covariance() 15 Correlation P 16 17 Calculating returns of combinations of Portfolio x and Portfolio y 18 Proportion of x 19 Mean portfolio return, r 0.01 0.30 0.06 -0.04 0.20 0.20 10.50% 0.1216 0.0714 0.4540 ? ? ? 0.3 0.03 0.06 0.40 0.02 0.30 0.10 ? 0.05 0.02 0.50 0.40 0.10 0.10 0.60 Mean, Er Variance, 0.2014 Question il Question ili Mean returns E(r) ? 7% 9% 11% 20% Question i i.

how to calculate a stocks average monthly returnn, its return variance, standard deviation and betas

Supposing the return from an investment has the following probability distribution   Return   Probability     R (%)   8                 0.2   10               0.2   12               0.5   14               0.1   Required: What is the expected return of the investment? What is the risk as measured by the standard deviation of  expected returns?

1. Using the following returns, calculate the average returns, the variance, standard deviations, and coefficient of variation for X and Y. Which stock is the least risky? Yr 1 2 3 Rx 12.20 9.65 0.00 6.50 Ry 4 8.00 -2.00 12.50 9.57
