# How (and why) does trading cointegration work?

Published 2026-08-10

Many explanations of how and why cointegration works, and what makes it a powerful tool, serve the uninitiated poorly. Forests of algebra do not make for approachability.

Worse, the links between cointegration and tradability are often assumed to be part of a reader’s knowledge – and that is when it is not being rashly implied that *cointegration = tradablility* and is thus enough to transact upon.

So we have put together this *[Quick Guide: Principles & Practicalities](https://arb-maker.com/wp-content/uploads/2012/06/Quick-guide-Principles-and-Practicalities.pdf)* to sketch out in simple terms the mechanics behind good potential trades. It focuses on situations where the pre-requisite of cointegration has already been established by ArbMakerPlus and helps answer the question “Now what?”
