About us

A conviction born in Switzerland

We are based in Switzerland, at the heart of a tradition where risk management is not a slogan but a discipline. That is where one conviction took shape: the strategies studied and published by finance research should not be reserved for people who can code.

Our mission

Make research-backed quantitative strategies accessible without code. PairScanner does a quantitative analyst's work: update the data, apply each rule, replay it on history and compute the useful numbers. You read the result in your browser, and you decide.

Six research-backed strategies

Each strategy has its own page, with a simple explanation, an example signal and its sources:

• Pair trading Gatev, Goetzmann and Rouwenhorst, 2006
• Momentum Jegadeesh and Titman, 1993
• Relative reversal Blitz, Huij, Lansdorp and Verbeek, 2013
• Short-term reversal Jegadeesh, 1990; Lehmann, 1990
• Statistical peers Chen, Chen, Chen and Li, 2019
• Lead-lag Cohen and Frazzini, 2008

How we compute

Every evening after the US close, our servers update prices from a professional financial data provider and apply the six strategies. Every signal shows the change that triggered it; for pair trading a success rate is added, with no fees, drawn from five years of the pair's history.

Every number is defined in plain words in the metrics dictionary. PairScanner connects to no broker and places no orders: you stay in control.

Our values

• Evidence-based: every strategy rests on published academic work, cited on its page.
• Mathematics-driven: statistical tests, validation on unseen data, false-discovery control; method before opinion.
• Trust: we show the freshness of the data and the sample size behind every number.
• Transparency: what the tool measures and how it measures it, all publicly documented.

A simple model

PairScanner is free during its development phase. We earn no brokerage commission and show no ads: our only interest is that the tool is useful to you.
