Correlation Coefficient:
The sign of the correlation coefficient shows whether the two stock prices are positively or negatively correlated. Positively correlated stock prices move in the same directions, and have a correlation coefficient that greater than zero, but not greater than +1. Negatively correlated stock prices move in opposite directions, and have a correlation coefficient that less than zero, but not less than -1.
The correlation coefficient's numerical value shows the strength of the correlation between the two ...
