Over the last two decades there has been much focus on how network theory can be used correlation coefficient between stock i and stock j. With this distance How to Calculate Stock Correlation Coefficient. It's often useful to know if two stocks tend to move together. To build a diversified portfolio, you would want stocks that do not closely track each other. The Pearson Correlation The correlation between any two variables tells you how closely their ups and downs mimic each other and is measured by a figure known as the correlation coefficient. A high positive correlation coefficient means the variables move up and down together. A high negative coefficient means that when one variable advances, the other tends to decline. 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 Stock Correlation Calculator. Use the Stock Correlation Calculator to compute the correlation coefficient using closing prices for any two stocks listed on a major U.S. stock exchange and supported by Quandl.. Simply enter any two stock symbols and select the price series and date information. 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. A correlation of -1 implies the two stocks will move in the opposite direction 100% of the time. When two stocks, for example, move in the same direction, the correlation coefficient is positive. Conversely, when two stocks move in opposite directions, the correlation coefficient is negative.
