Pairs Trading Strategy

Pairs trading is a market-neutral strategy that exploits temporary divergences between two historically correlated stocks. By going long the underperformer and short the outperformer, you profit when the spread converges — regardless of overall market direction.

How It Works

  1. 1

    Identify stock pairs with high historical correlation (r > 0.8) within the same sector

  2. 2

    Calculate the z-score of the price ratio or spread between the two stocks

  3. 3

    Enter when the z-score exceeds 2 standard deviations (long the laggard, short the leader)

  4. 4

    Exit when the z-score returns to 0 (spread has normalized)

  5. 5

    Set a stop if the z-score exceeds 3 standard deviations (divergence is structural)

What is pairs trading?
