This paper argues that inferring long-horizon asset-return predictability from the properties of vector autoregressive (VAR) models on relatively short spans of data is potentially unreliable. We illustrate the problems that can arise by re-examining the findings of Bekaert and Hodrick (1992),...

This paper extends the genetic programming techniques developed in Neely, Weller and Dittmar (1997) to provide some evidence that information about U.S. foreign exchange intervention can improve technical trading rules' profitability for two of four exchange rates over part of the out-of-sample...

Using genetic programming, we find trading rules that generate significant excess returns for three of four EMS exchange rates over the out-of-sample period 1986-1996. Permitting the rules to use information about the interest rate differential proved to be important. The reduction in volatility...

This paper examines the out-of-sample performance of intraday technical trading strategies selected using two methodologies, a genetic program and an optimized linear forecasting model. When realistic transaction costs and trading hours are taken into account, we find no evidence of excess...

This paper describes the use of genetic programming to create trading rules based on past exchange rates and interest differentials. In an out-of-sample period, 1986-1996, these rules make significantly positive excess returns for three of four EMS exchange rates. There is evidence that the...

Using genetic programming techniques to find technical trading rules, we find strong evidence of economically significant out-of-sample excess returns to those rules for each of six exchange rates, over the period 1981-1995. Further, when the dollar/deutschemark rules are allowed to determine...
