## Definition of 'Positive Correlation'

Positive correlation is a statistical relationship between two variables in which the values of one variable tend to increase as the values of the other variable increase, and vice versa. In other words, positive correlation means that the two variables are moving in the same direction.

For example, the price of a stock and the volume of trading in that stock are positively correlated. As the price of the stock increases, the volume of trading tends to increase as well. This is because when the price of a stock increases, more investors are interested in buying it, which leads to increased trading volume.

Another example of positive correlation is the relationship between the interest rate and the value of a bond. As the interest rate increases, the value of a bond tends to decrease. This is because when the interest rate increases, bonds become less attractive to investors, who can earn a higher return by investing in other types of investments, such as stocks.

Positive correlation is not always the case. Sometimes, two variables may be negatively correlated, which means that as the values of one variable increase, the values of the other variable decrease. For example, the price of a stock and the dividend yield on that stock are negatively correlated. As the price of a stock increases, the dividend yield tends to decrease. This is because when the price of a stock increases, investors are willing to pay more for the stock, which means that the company has to pay out less in dividends in order to keep its stock price high.

It is important to note that correlation does not imply causation. Just because two variables are correlated does not mean that one variable causes the other variable. For example, the price of a stock and the volume of trading in that stock are positively correlated, but this does not mean that the volume of trading causes the price of the stock to increase. Rather, it is more likely that both variables are being influenced by some other factor, such as the overall performance of the stock market.

Positive correlation is a useful tool for financial analysis. It can help investors to identify potential investment opportunities and to manage their risk.
