Do Momentum-Based Strategies Still Work in Foreign Currency Markets?

This paper examines the performance of momentum trading strategies in foreign exchange markets. We find the well-documented profitability of momentum strategies during the 1970s and the 1980s has continued throughout the 1990s. Our approach and findings are insensitive to the specification of the trading rule and the base currency for analysis. Finally, we show that the performance is not due to a time-varying risk premium but rather depends on the underlying autocorrelation structure of the currency returns. In sum, the results lend further support to prior momentum studies on equities. The profitability to momentum-based strategies holds for currencies as well.
