The Quant Secret Weapon: Win Trades Like Clockwork With Markov Chains

In today’s edittion, I’m going to break down how hedge funds use Markov Chains to find high probability winning trades consistently & share the exact framework you can start building today.

Overview

Most traders look at a chart and see price.

Most traders look at a chart and see price.

Quants look at the same chart and see something completely different. They see a sequence of states. Bull. Bear. Sideways. Each state carrying its own probability of persisting or transitioning into the next one. Each transition governed by mathematics that has been used to model everything from loan defaults to DNA sequences to Google’s original PageRank algorithm.

The framework is called a Markov Chain. And it is one of the most versatile and underused tools in systematic trading.

While most retail traders are drawing support lines and watching RSI, the quantitative research teams at firms like Citadel and Two Sigma are building regime-switching models that understand not just where the market is, but where it is most likely to go next based on where it has been. The math behind those models starts exactly here.
