What do correlations in finance measure?

Correlations in finance measure the degree to which two assets move in relation to each other. This statistical measure identifies how closely the movements of two different financial instruments are related. A positive correlation indicates that the assets tend to move in the same direction; for example, if one asset's price increases, the other asset is likely to increase as well. Conversely, a negative correlation suggests that the assets move in opposite directions. Understanding these relationships is crucial for investors and portfolio managers as it helps in diversification strategies and risk management. By analyzing correlations, investors can better anticipate how assets will behave in different market conditions and adjust their portfolios accordingly to achieve desired risk-return profiles.

The other options emphasize various aspects of finance but do not accurately capture the essence of correlation as it specifically relates to the relationship between the movements of two assets.
