Quick Definition

Correlation in finance measures the degree to which two securities move in relation to each other, indicating how investments might behave under similar market conditions.

Formula

Correlation coefficient, r = Σ[(Xi - X̄)(Yi - Ȳ)] / [√(Σ(Xi - X̄)²) * √(Σ(Yi - Ȳ)²)]

Examples

  • 1If stock A and stock B have a high positive correlation, when stock A's price increases, stock B's price is likely to increase as well.
  • 2A negative correlation between gold and the stock market often means that when stocks go down, gold prices might rise, serving as a hedge.
  • 3Correlation between currency pairs in Forex trading can help traders manage risk and develop strategies.
