What is the definition of stat arb?
Statistical arbitrage or stat arb is a quantitative trading strategy that involves exploiting the pricing inefficiencies in the market. The strategy relies on the use of statistical models to identify market anomalies and profit from them. The core principle of stat arb is to identify two or more securities that are mispriced relative to each other and take offsetting positions in them to generate profit. In this blog post, we will discuss stat arb in detail and provide three examples of successful stat arb trades.
Examples of companies that use stat arb.
Example 1: Renaissance Technologies
Renaissance Technologies is a hedge fund that is widely regarded as one of the pioneers of stat arb trading.
