⎊ This approach to trading relies on identifying statistical relationships between two or more assets or instruments that are expected to revert to a historical mean or cointegrated path. The strategy does not rely on fundamental valuation but rather on the probabilistic expectation of price convergence. Developing robust cointegration tests is a prerequisite for any viable implementation.
Signal
⎊ The trading signal is generated when the observed deviation between the actual price relationship and the expected statistical norm exceeds a predefined threshold, often measured in standard deviations. This deviation suggests a temporary mispricing that the market will eventually correct. Sophisticated quantitative analysts focus on minimizing false positives through rigorous statistical testing.
Trade
⎊ Execution in this domain is typically high-frequency, requiring low-latency infrastructure to capture the ephemeral profit opportunity before mean reversion occurs. The position sizing must be inversely proportional to the confidence level derived from the statistical analysis. Successful deployment demands superior computational resources and precise trade management.
