- H shares which have corresponding A shares listed on the exchanges in Mainland China
- All ETFs
List of CAS Securities 
https://www.hkex.com.hk/eng/market/sec_tradinfra/vcm_cas/Documents/List%20of%20CAS%20securities.xls

Under the CAS, the market closing time will change from 16:00 to a random closing of anytime between 16:08 and 16:10 for a normal trading day and it will change from 12:00 to a random closing of anytime between 12:08 and 12:10 for a half trading day (i.e. eves of Christmas, New Year and Chinese New Year).

The below are the details of the CAS and the trading arrangement:

Random Closing Period16:08 - 16:1012:08 - 12:10Input allowed, Admen/ Cancel not allowed


Notes:

  • The reference price is determined by taking the median of 5 nominal prices in the last minute of the Continuous Trading Session and the system will take 5 snapshots on the nominal prices at 15-second interval starting from 15:59:00.

  • Order Input Period: At-auction orders and at-auction limit orders within the ±5 per cent of reference price as price limit.

  • No Cancellation Period: At-auction orders and at-auction limit orders can be entered. At-auction limit orders must be between the lowest ask & highest bid recorded at the end of Order Input Period (i.e. recorded at 16:06). 

  • Orders outstanding at the end of the preceding Continuous Trading Session will be automatically carried forward to the CAS and treated as at-auction limit orders except that the system will cancel those aggressive orders with prices outside the permissible price limit.

  • The market closing time for non CAS securities, structured product (i.e. DWs and CBBCs) and short-selling will continue to be 16:00 for full day trading and 12:00 for half day trading. 

  • The price checking in relation to 24-spread rule is not applicable during CAS; while the 9-time rule for at-auction limit order is applicable as usual during CAS.


Details about CAS is available on HKEX website.

HKEX has adopted a dynamic price limit VCM model, which would trigger a cooling-off period in case of abrupt price volatility detected at the instrument level.


The VCM is only applicable for board lot order input during the Continuous Trading Session (CTS), but not for any orders input during the Pre-opening Session (POS) and the CAS.


During the CTS, the potential trade price of a VCM security will be continuously checked against a dynamic price limit of ±10%, ±15% and ±20% for Hang Seng Composite LargeCap, MidCap and SmallCap Indexes constituent stocks respectively based upon the reference price which is the last traded price 5 minutes ago.


The VCM is triggered if a stock is ±10%, ±15% and ±20% away (for Hang Seng Composite LargeCap, MidCap and SmallCap Indexes constituent stocks respectively) from the last traded price 5-min ago; A 5-min cooling-off period will start.


Normal trading and VCM monitoring will resume on the VCM-triggered instrument after the cooling-off period.
