Correlation, in the finance and investment industries, is a statistic that measures the degree to which two securities move in relation to each other. Correlations are used in advanced portfolio management , computed as the correlation coefficient, which has a value that must fall between -1.0 and +1.0. The Correlation Coefficient is positive when both securities move in the same direction (up or down) and negative when the two securities move in opposite directions. Determining the relationship between two securities is useful for analyzing intermarket relationships, sector-stock relationships and sector-market relationships. Stock correlation describes the relationship that exists between two stocks and their respective price movements. It can also refer to the relationship between stocks and other asset classes, such as bonds or real estate. 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. A correlation of zero implies that the relationship between the stocks is completely random. When correlation coefficient is -1 the portfolio risk will be minimum. Markowitz has shown the effect of diversification by reading the risk of securities. According to him, the security with covariance which is either negative or low amongst themselves is the best manner to reduce risk.
