Working Papers from African Economic Research Consortium

Abstract: Previous studies on the Nigerian parallel market found "return predictability". Based on this finding, we quantify, using Hansen's GMM estimation technique, the risk-return charateristics implicit in the simplest trading strategy of "buy and hold" an optimal portfolio of currencies. The risk-return profile suggests that profitable trading opportunities found in the Nigerian market may not indeed be exploitable.
