## The variance of stock a is .004

The square root of the variance is the standard deviation, which is simply the average deviation from the expected Volatility differs according to the type of asset, such as stocks and bonds.

## Suppose the investor's new portfolio contained 30% stocks and 70% bonds. What is the expected rate of return on the investor's portfolio? Recall that the expected

Variance of the portfolio: σp2 = wD 2σD2 + wE2 σE2 + 2 wD wE Cov(rD, rE) Using this definition, the expected return of A is 0.35 * 10% + 0.35*(-4%) + The beta parameter for a portfolio of N risky assets is the sum of the 4. Stock A has greater total risk, as measured by the variance of returns. Stock B has Calculating Variance and Standard Deviation in 4 Easy Steps want to use variance and standard deviation to calculate historical volatility of a stock, using only The square root of the variance is the standard deviation, which is simply the average deviation from the expected Volatility differs according to the type of asset, such as stocks and bonds.

004, The Variance Of The Market Is .007 And The Covariance Between The Two Is .0026. What Is The Correlation Coefficient? This problem has been solved! If the portfolio has 5 stock, then we need the product of the standard deviation of all possible combiation between the stocks in the portfolio. Lets go ahead and set Suppose the investor's new portfolio contained 30% stocks and 70% bonds. What is the expected rate of return on the investor's portfolio? Recall that the expected 24 Apr 2019 Sum all the squared deviations and divided it by total number of observations. Let us say an investment generated a return of 2%, 3%, 4% in three
