of average correlations were observed during market stress periods. More recently, Kenett et al. (2015) applied partial correlation analysis to stock prices by   A high positive correlation coefficient means the variables move up and down Calculate the average price for each stock by adding up daily prices and

Asset Correlations. This asset correlation testing tool allows you to view correlations for stocks, ETFs and mutual funds for the given time period. You also view the rolling correlation for a given number of trading days to see how the correlation between the assets has changed over time. Calculating Stock Correlation. The deviation is the stock’s price on a given day, minus the average price. So if a stock’s average price is \$25 per share and the daily price is \$26.50 for a particular day, the deviation would be -\$1.50. You’ll do this calculation for each day in the time period you’re measuring for each stock. Stock Correlation Analysis. Use correlation to identify herd behavior The clustering algorithm analyzes past price movements to construct charts in such a way as to reveal relationships between stocks that would typically go unnoticed.

Stock Correlation - Explanation Stock Correlation is the statistical measure of the relationship between two stocks. The correlation coefficient ranges between -1 and +1. A correlation of +1 implies that the two stocks will move in the same direction 100% of the time. The random walk theory is suited for a stock’s price prediction because it is rooted in the believe that past performance is not an indicator of future results and price fluctuations can not be predicted with accuracy.

The correlation between American stock prices and the U.S. dollar comes down to the two variables having a correlation coefficient between -1 and +1.

## For example, the stock price of a gold mining company might be positively related to the price of gold (with a high, positive correlation coefficient). If the price of gold is expected to increase, an investor would have reason to believe that the price of the company's stock will as well.
