Knowing the correlation of investment returns among your assets is key to having a thriving and diverse portfolio, and you've got options for figuring it out. A little bit of finagling in a Microsoft Excel spreadsheet or some quick data entry in an online calculator will get you there in no time. If the coefficient correlation is zero, then it means that the return on securities is independent of one another. When the correlation is zero, an investor can expect deduction of risk by diversifying between two assets. When correlation coefficient is -1 the portfolio risk will be minimum. Calculating the correlation of stock A with stock B. Ask Question Asked 3 years, 5 months ago. Stock B has a beta of .95 and a volatility of 33 percent. If the market volatility is 20 percent, what is the correlation of stock A with stock B? Which stock has higher residual volatility? Is there a nice formula for the first part of the Portfolio standard deviation is the standard deviation of a portfolio of investments. It is a measure of total risk of the portfolio and an important input in calculation of Sharpe ratio. One of the most basic principles of finance is that diversification leads to a reduction in risk unless there is a perfect correlation between the returns on the portfolio investments.
The Correlation Coefficient is positive when both securities move in the same direction (up or down) and negative when the two securities move in opposite directions. Determining the relationship between two securities is useful for analyzing intermarket relationships, sector-stock relationships and sector-market relationships.

In finance, the beta of an investment is a measure of the risk arising from exposure to general Beta is also referred to as financial elasticity or correlated relative volatility, and can be referred to as a measure of the sensitivity of the asset's The equation of the SML, giving the expected value of the return on asset i, is thus:.
The primary use of stock correlation coefficients is in the preparation of balanced securities portfolios. Stocks or other assets within a portfolio can be assessed against others in the same portfolio to determine the correlation coefficient between them. The goal is to place stocks with low or negative correlations in the same portfolio. Correlation Coefficient: The correlation coefficient is a measure that determines the degree to which two variables' movements are associated. The range of values for the correlation coefficient The correlation coefficient that indicates the strength of the relationship between two variables can be found using the following formula: Where: r xy – the correlation coefficient of the linear relationship between the variables x and y; x i – the values of the x-variable in a sample; x̅ – the mean of the values of the x-variable If the correlation is 1, they move perfectly together and if the correlation is -1 then stock moves perfectly in opposite directions. Or if there is zero correlation then there is no relations exist between them. Examples of Covariance Formula. Let’s take an example to understand the calculation of Covariance in a better manner.

Simply enter any two stock symbols and select the price series and date information. Formula to Calculate Covariance. Covariance is a statistical measure used to find the relationship between two assets and its formula calculates this by looking at the standard deviation of the return of the two assets multiplied by the correlation, if this calculation gives a positive number then the assets are said to have positive covariance i.e. when the returns of one asset goes up, the
