Pairs trading

Abstract: 'Pairs Trading' is an investment strategy used by many Hedge Funds. Consider two similar stocks which trade at some spread. If the spread widens short the high stock and buy the low stock. As the spread narrows again to some equilibrium value, a profit results. This paper provides an analytical framework for such an investment strategy. We propose a mean-reverting Gaussian Markov chain model for the spread which is observed in Gaussian noise. Predictions from the calibrated model are then compared with subsequ… Show more

“…All of these share pairs produce cointegration error with AR(1) processes. Elliott (2005) and Herlemont (www.yats.com) also suggested AR(1) processes for modeling pairs trading, but they used the Ornstein-Uhlenbeck process which is the continuous-time counterpart of an AR(1) process to estimate the optimal boundaries. However, due to the complexity of stochastic analysis in the Ornstein-Uhlenbeck process, their results are difficult to be applied in practical situation.…”

“…The simplest special case of these strategies is perhaps pairs trading (see Elliott, van der Hoek, & Malcolm, 2005;Gatev, Goetzmann, & Rouwenhorst, 2006). In this case, two assets are initially chosen by the trader, usually based on an analysis of historical data or other financial considerations.…”

“…Vidyamurthy (2004) details an implementation strategy based on a cointegration-based framework, without empirical results. Elliott et al (2005) apply a Kalman filter to estimate a parametric model of the spread. These methods can be shown to be applicable for special cases of the underlying equilibrium relationship between two stocks.…”
