Abstract
Convex Strategies on the Exchange Market: Forecasting Ability and Economic Value
The subject of this empirical study is the predictability of deviations, defined as yield on foreign exchange transactions, from the forward rate parity for five rates of exchange in the period 1977/88. Starting from the question whether such deviations are predictable and not random in character, this paper analyzes the yield on foreign exchange transactions for regularity. The following shows that, where foreign exchange transaction yields auto-correlate in a positive sense, a convex investment behaviour is advantageous and that the Trading Rules set out in the “technical analysis” may be referred to as convex in nature. The forecasting value of the strategies examined has been analyzed on the basis of both the Henriksson/Merton and the Cumby/ Modest tests. On this basis, the economics element involved in the forecasting value is ascertained with the help of the options price theory. Simulation runs covering the period 1977/1988 have confirmed the results obtained. It is subsequently -shown that optimal strategy implementation by investors depends not only on the quality of the forecasts made, but also on individual risk aversion.
