In financial markets, noise is constant — but logic endures. Behind the short-term volatility and narrative churn lies a deeper structure: the relationships between assets, sectors, and flows. These relationships can be measured, modeled, and traded. That’s the essence of a statistical arbitrage edge — and the foundation of our work at PairTrade Finder®.
This October, after hundreds of hours of research, recalibration, and validation, we’re releasing the October 2025 Vintage of our Top 50 USA Stock Pair Stars — a selective, systematically refined collection of high probability USA stock pairs to drive your statistical arbitrage edge. Here are the results of the Last 12 Months Backtest, which includes 31 pairs “out-of-sample/live” and 19 new pairs “in-sample”:

And here are the results of the full Three-Year Backtest for the same pair set:
Each figure represents a modelled observation, not a guarantee. What matters most is the process discipline that produces these results — the repeatability of the method. Full details of the pair selection universe and backtesting filter applied are available HERE.
The Philosophy Behind the Work
Markets are efficient most of the time. What creates edge is not prediction, but identifying small, repeatable inefficiencies in relative value — and capturing them consistently while managing risk.
That is what we mean by a statistical arbitrage edge: disciplined exploitation of temporary mispricings between fundamentally linked equities.
Rather than chasing momentum or headlines, this approach begins with cointegration and correlation testing across U.S. equities. Pairs that demonstrate stable, statistically significant long-term relationships are retained; those that do not are discarded. The surviving set becomes our trade universe.

The Broader View on a Statistical Arbitrage Edge
The edge in statistical arbitrage is not found in any one trade. It lies in the process — the continual refinement of models, data integrity, and disciplined risk control. Over time, small edges, repeated consistently, compound into something meaningful.
The October 2025 Vintage reflects that philosophy. It is not a prediction; it is preparation.
