  • Customers will be able to better tap Hong Kong’s market, managing their risk and capitalizing on opportunities


Hong Kong Exchanges and Clearing Limited (HKEX) is pleased to announce today (Monday) that it is to extend its after-hours trading session (T+1 Session) by two hours. Effective Monday 17 June 2019, trading in the T+1 Session will be open from 5:15 pm to 3 am. As well, the T+1 Session Cutoff Time (the deadline for system input of post-trade after the T+1 Session) will be extended from 1:45 am to 3 am.

Calvin Tai, HKEX’s Co-President and Chief Operating Officer said, “We are committed to continuously improving our trading platform to meet investment and risk-management needs of our customers around the world.  This latest enhancement will provide them greater flexibility to capture investment opportunities during the US market hours and effect timely risk-management actions.

HKEX announced plans in 2017 to enhance after-hours trading on its markets, to 3 am, in phases.  Trading in the T+1 Session was extended to 1 am the next day, from 11:45 pm, in November 2017; while options contracts, as well as a trading halt mechanism for index options in the T+1 Session, were introduced in May 2018.  

The T+1 Session has proven to be very popular with investors since it was launched in 2013 to initially offer trading in equity index futures, while products of other asset classes including currencies and commodities were progressively included in the T+1 Session.  Futures trading volumes in the T+1 Session has seen a 50 per cent compound annual growth rate since 2013, and now1 accounts for around 18 per cent of the day trading session, compared with 4 per cent in 20132.  

Equity index options, which were added to the T+1 Session last year, now account for nearly 7 per cent of day trading session, with over 10,500 contracts traded during each session.
