Why is covariance important?
Maybe I'm not providing a full information. But if you're asking about importance of covariance in trading, then before investing you should assess if your stocks are codependent. All investors try to diversify a portfolio and minimize risks. and covariance can show if two stocks are exposed to the same risk. Now it's easily calculated, there're different services. Actually, for better understanding just read Investopedia really.

How do you calculate variance covariance matrix for daily market prices of stock in excel?
To calculate the variance-covariance matrix for daily market prices of stocks in Excel, first, gather the daily prices of the stocks in a spreadsheet. Convert these prices into daily returns by using the formula: ( \text{Return} = \frac{\text{Price Today} - \text{Price Yesterday}}{\text{Price Yesterday}} ) for each stock. Once you have the daily returns, use the Excel function =COVARIANCE.P(array1, array2) to calculate the covariances between each pair of stock returns, and =VAR.P(array) for the variances of individual stock returns. Finally, organize these values into a matrix format to represent the variance-covariance matrix.

What is degrees of freedom of covariance?
Degrees of freedom in the context of covariance typically refer to the number of independent values that can vary in the calculation of the covariance between two variables. When calculating sample covariance, the degrees of freedom are often adjusted by subtracting one from the sample size (n-1) to account for the estimation of the mean values from the same data set. This adjustment helps provide a more accurate estimate of the population covariance. Therefore, the degrees of freedom for covariance in a sample of size n is generally n-2, as both variables' means are estimated from the data.

How do you find covariance of two variables?
The covariance between two variables is simply the average product of the values of two variables that have been expressed as deviations from their respective means. ------------------------------------------------------------------------------------------------- A worked example may be referenced at: http://math.info/Statistics/Covariance
What is the meaning of analysis of covariance?
A mix of linear regression and analysis of variance. analysis of covariance is responsible for intergroup variance when analysis of variance is performed.
What is difference between covariance and variance?
Covariance: An Overview. Variance refers to the spread of a data set around its mean value, while a covariance refers to the measure of the directional relationship between two random variables.
