Efficient Selection of Insured Currency Positions: Protective Puts vs. Fiduciary Calls

We examine the empirical results from implementation of portfolio insurance strategies employing currency spot and futures options. Hypotheses are generated from Ogden and Tucker's (1988) generalizations concerning the relative values of American spot currency options and currency futures options. We find that protective puts using futures options are generally dominated by both protective puts that use options on spot currencies and by fiduciary calls on futures contracts. This suggests that the prices of puts on foreign currency futures contracts are too high, relative to foreign currency futures calls and to puts on spot currencies.
