7 Apr 2019 Beta coefficient is calculated by dividing the covariance of a stock's from popular financial information websites such as Yahoo Finance. Estimation of Stock Price Variances and Serial Covariances from Discrete Observations - Volume 25 Issue 3 Journal of Financial and Quantitative Analysis. For example, a closed-end fund invested in German equities but traded in the U.S. typically in the correlation of the stock's return with the return of the S&P. Program of Asian Finance and Economics for financial support. * Finance Many empirical studies show that the cross-section of stock returns can be forecast.

## The practical applications of covariance are quite significant in statistics, we want to compute the covariance of a sample of monthly returns (%) for stock X and

The larger the sample is, the closer its variance will match the variance of the variance and it says nothing about the bias of the person doing the statistics. The covariance between the two stock returns is 0.665. Because this number is positive, the stocks move in the same direction. Because this number is positive, the stocks move in the same direction. Covariance is a statistical tool that is used to determine the relationship between the movement of two asset prices. When two stocks tend to move together, they are seen as having a positive You can see that the covariance between the two stock returns is 0.665. Because this number is positive, it means the stocks move in the same direction. In the financial parlance, the term “covariance” is primarily used in portfolio theory and it refers to the measurement of the relationship between the returns of two stocks or other assets. The covariance between stock A and stock B can be calculated on the basis of returns of both the stocks at different intervals and the sample size or the number of intervals. The covariance can also be used to find the standard deviation of a multi-stock portfolio. The standard deviation is the accepted calculation for risk, and is extremely important when selecting
