This paper studies the trading of Hang Seng Index futures contracts on the Hong Kong Futures Exchange since the Exchange began to open earlier and close later than the underlying cash market by 15 min. We show that the extension of trading hours stimulates the opening trading volume of the futures market. Futures returns surrounding the market opening are found to be relatively less volatile with insignificant change in pricing errors when compared with the pre-extension period. These observations suggest that activities during the extended opening session are related with private information but not with public information or noise.
