Stock Quote Correlation
Is there a relation between the stock prices of two quotes? The Stock Quotes Correlation analysis attempts to measure the strength of such relationships by means of a single number varying between 1 to 1 called correlation coefficient.
 +1.0 is a perfect match (if one quote goes up, the other one follow).
 1.0 is perfect negative (inverse) correlation (if one quote goes down, the other one go up).
 0.0 is no correlation (random).
