We test whether exchange rate trading is profitable in the emerging markets of Brazil, China, India, and South Africa. Using momentum trading strategies applied to high frequency data, we discover that: (a) momentum-based trading strategies lead to statistically significant profits from the currencies of all four emerging markets; (b) the South African Rand is generally the most profitable, followed by the Brazilian Real and the Indian Rupee; (c) profits are persistent during the day and are trading frequency dependent; and (d) during the period of the global financial crisis currency profits were maximised.
