Abstract

The Sydney Futures Exchange is one of the few exchanges world-wide where the options traded on the exchange are subject to futures-style margining. In this paper the valuation equation relating to pure futures options (the Asay model) is reviewed and the pricing performance of the model is examined on transaction prices from the SPI futures option market for the period from 1 June 1993 through to 30 June 1994. The Asay model is shown to generate significant pricing errors. These errors are related to the degree of moneyness and the maturity of the option. The errors are consistent with an observed smile in the implied volatilities.
