HKEX schedules 12 new stock-option classes for 9 November, extending weekly expiry coverage

HKEX announced on 12 October that 12 additional stock-option classes, including one ETF underlying, are scheduled to start on 9 November 2026. Each class will offer weekly and monthly expiries. The expansion will bring weekly-option coverage to 66 stocks or ETFs.[1]

The first weekly expiries are 13 and 20 November. The initial monthly schedule covers November and December 2026, followed by January, February, March, June and September 2027.[1]

Contract size is the implementation detail that matters

The multipliers range from 100 to 4,000 shares or units. Comparing premiums per share can therefore conceal large differences in the cash amount and underlying exposure of one contract. Brokers must load the correct multiplier into order validation, margin calculations and customer confirmations.[1]

For example, a hypothetical premium of HK$0.50 would represent HK$50 on a 100-share contract and HK$2,000 on a 4,000-unit contract, before charges. This is an arithmetic illustration, not a market quote or a comparison of actual contract values.[1]

A scheduled exchange launch also leaves a separate distribution question: whether a client’s broker supports the class, the requested expiry and the relevant options permission. The announcement establishes the exchange timetable; it does not guarantee access or liquidity through every intermediary.[1]
