Stock portfolio correlation coefficient
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. Note that since the correlation coefficient is a statistical measure, a perfectly uncorrelated pair of investments will rarely, if ever, have an exact correlation coefficient of zero. The most diversified portfolio consists of securities with the greatest negative correlation. A working example. To demonstrate how the correlation analysis could be applied in practice, let's assume an investor holds a simple portfolio that is 75% invested in US stocks (NYSEARCA:VTI) and

That is, how closely the return values satisfy a linear relation such as Y = βX + α for some constants α and β. Correlation statistics can be used in finance and investing. For example, a correlation coefficient could be calculated to determine the level of correlation between the price of crude oil and the stock price of an oil-producing company, such as Exxon Mobil Corporation. Stock analysts use a measure called the correlation coefficient to make predictions about how a stock will behave based on past performance and the activity of another security with which the Stock Correlation Calculator.
