Abstract:

Pairs trading is a type of risk-neutral quantitative strategy. By analyzing the pairs trading principal and observing the actual market data, this paper proposes a new type of execution methods for pairs trading strategy based on the work carried out by Bertram(2010). Using the out-of-sample data to simulate real trading and demonstrate the pros and cons of different methods, we find that the trading strategy based on co-integration theory and OU stochastic process has a better returns expectation given the same risk exposure and the result of the strategy is solid.

Key words: pairs trading, co-integration, OU process, quantitative strategy
