Optimal switching for the pairs trading rule: A viscosity solutions approach

 http://repository.vnu.edu.vn/handle/VNU_123/26862
This paper studies the problem of determining the optimal cut-off for pairs trading rules.

We consider two cointegrated assets whose spread is modelled by a general mean-reverting process, and the optimal pair trading rule is formulated as an optimal switching problem between three regimes: flat position (no holding stocks), long one short the other and short one long the other.



A fixed commission cost is charged with each transaction.

We use a viscosity solutions approach to prove the existence and the explicit characterization of cut-off points via the resolution of quasi-algebraic equations.

We illustrate our results by numerical simulations.
