Table A.III<br />
<strong>Option</strong>-<strong>Implied</strong> <strong>Currency</strong> <strong>Risk</strong> <strong>Premia</strong>: Empirical factor mimicking portfolio returns<br />
(Specification II; constant global factor loadings)<br />
The table compares the historical (realized) returns to factor mimicking portfolios, with the corresponding model-implied risk<br />
premia. The data span the period from January 1999 to June 2012 (N = 162 months). Realized returns are computed on the basis<br />
of monthly buy-and-hold returns. The conditional HML F X factor mimicking portfolios is a dollar-neutral portfolio formed by<br />
sorting currencies into long and short portfolios on the basis of their prevailing one-month LIBOR rates. Within each portfolio<br />
currencies are spread weighted, on the basis of the distance of their respective interest rates to the mean of the interest rates in<br />
countries with ranks five and six. The unconditional HML F X portfolios is formed on the basis of the historical interest rate<br />
differentials computed using an expanding window starting in January 1990. The conditional short USD factor mimicking goes<br />
long (short) the U.S. dollar when the prevailing U.S. dollar interest rate is above (below) the prevailing average of the nine other<br />
G10 interest rates. The unconditional short USD factor mimicking portfolio is long an equal-weighted basket of G10 currencies<br />
against the U.S. dollar. Model risk premia are computed on the basis of Specification II. We report the moments of various<br />
quantities of interest, the p-values of the Jarque-Bera test for the realized portfolio returns, and comparisons of the mean realized<br />
and model-implied risk premia (t-stats in square brackets).<br />
