The process of identifying price discrepancies in statistical arbitrage is a sophisticated exercise that requires a deep understanding of both financial markets and statistical modeling. This core aspect of statistical arbitrage involves several nuanced steps and considerations.

The foundation of identifying price discrepancies lies in the development of robust predictive models. These models are constructed using historical market data, incorporating various statistical and econometric methods to forecast the expected prices of assets. Techniques might include regression analysis, machine learning algorithms, and mean reversion models, among others. The accuracy and reliability of these models are critical, as they directly influence the ability to identify profitable arbitrage opportunities.

Once the models are developed, statistical arbitrage strategies rely on real-time market data feeds to continuously compare the live market prices of assets against the prices predicted by the models. This real-time analysis requires sophisticated technology infrastructure capable of processing high volumes of data with minimal latency to ensure that opportunities can be captured as they arise.

Price discrepancies may result from a range of factors, including temporary supply and demand imbalances…
