Using an Ornstein–Uhlenbeck Model to Identify Mean-Reverting Regimes
Summary
This document presents an Ornstein–Uhlenbeck (OU) process as a framework for distinguishing mean-reverting behavior from persistent drift. It contrasts the model with conventional volatility bands, arguing that bands around a moving average do not by themselves establish that prices have a statistical pull toward a baseline. The proposed matrix estimates an equilibrium level, reversion speed, and diffusion scale, then displays channels around the estimated equilibrium.
Its suggested procedure is to check that estimated reversion speed is positive before trading for convergence, and to avoid mean-reversion execution when the model indicates drift. The text supplies the OU equation and describes the parameters, but gives no data, estimation details, validation, or performance results. Its claims about standard bands and the accuracy of the indicator are unsupported in the document, so the approach should be viewed as a proposed framework rather than demonstrated trading evidence.
Key ideas
- The OU process models movement toward an estimated equilibrium level amid stochastic noise.
- The described matrix uses equilibrium, reversion-speed, and diffusion estimates to define channels.
- The proposed rule is to consider convergence trades only when estimated reversion speed is positive.
- The document provides no estimation procedure, empirical validation, or strategy performance evidence.
- Its broad criticism of conventional volatility bands is asserted rather than supported with analysis.
