A synthetic asset based on the cointegration relationship of the stocks with Index was constructed. The classic stat arb strategy is pairs trading, which involves finding two assets that are highly correlated and trading the spread between them. In order to capture the dynamic of the market time adaptive algorithms have been developed and discussed. Trading signals are based on the z-score, given they pass the test for co-integration. I set up three tests, each with a different number of observations (120, 90, 60), all three tests have to reject the null hypothesis that the pair is not co-integrated. FX Statistical Arbitrage. But since you can’t trade the NAV, although you are still able to make bets on convergence (by going long the CEF when it is trading at a discount), such bets would not be pure bets on the spread.
