TY - JOUR T1 - Optimal Portfolios of Foreign Currencies JF - The Journal of Portfolio Management SP - 102 LP - 111 DO - 10.3905/jpm.2001.319826 VL - 28 IS - 1 AU - Jamil Baz AU - Francis Breedon AU - Vasant Naik AU - Joel Peress Y1 - 2001/10/31 UR - https://pm-research.com/content/28/1/102.abstract N2 - Empirical evidence suggests that forward exchange rates are biased predictors of future spot exchange rates. Currencies with higher nominal interest rates tend to appreciate rather than depreciate as predicted by the forward rates. Simultaneously, exchange rates also turn out to be notoriously difficult to predict using plausible macroeconomic variables. The authors demonstrate how these two hypotheses can be combined with standard mean–variance analysis to construct optimal currency portfolios. They simulate the optimal portfolio strategies on historically observed data for the period 1989–1999 for DEM, JPY, GBP, and CHF (with the USD as the base currency). These portfolios generate positive excess returns. Moreover, the returns on optimal currency portfolios do not appear to be correlated with the returns on major fixed–income and equity indexes. These findings suggest that the methodology can provide a useful benchmark against which to evaluate more elaborate active currency strategies. ER -
