WebExample: Find the standard deviation of the numbers given (3, 8, 6, 10, 12, 9, 11, 10, 12, 7). Step 1: First compute the mean of the 10 values given. Step 2: Make a table as … WebIn reality, the correlation coefficient between returns on investments tends to lie between 0 and +1. It is the norm in a two-asset portfolio to achieve a partial reduction of risk (the standard deviation of a two-asset portfolio is less than the weighted average of the standard deviation of the individual investments).
Websp = s1 + x2*(s2-s1) ep = e1 + x2*(e2-e1) and all such portfolios will plot on a straight line connecting the points representingthe two assets.

Because it's a …
WebAlso, let's assume that the portfolio weights are w1 = 0.3 for asset 1 and w2 = 0.7 for asset 2. The formula for the standard deviation of a portfolio with two assets is given by: σp = sqrt(w1^2 * σ1^2 + w2^2 * σ2^2 + 2 * w1 * w2 * ρ * σ1 * σ2) where σ1 and σ2 are the standard deviations of assets 1 and 2, respectively. WebStandard Deviation = 3.94. Variance = Square root Square Root The Square Root function is an arithmetic function built into Excel that is used to determine the square root of a given number. To use this function, type …
WebAfter incorporating covariance, the standard deviation of a two-asset portfolio can be calculated as follows: Standard Deviation of a two Asset Portfolio. In general as the correlation reduces, the risk of the portfolio reduces due to the diversification benefits. Two assets a perfectly negatively correlated provide the maximum diversification ...
