Frequently Asked Question

No. The HKExH K E x only accepts board lot trading on CBBC for both buy and sell orders. While other trading arrangement is the same as that for listed shares.

CBBC will be called immediately when the price of the underlying asset reaches a pre-determined level known as the Call Price before the expiration date (“Mandatory Call Event”). The issuer of the CBBC informs HKExH K E x about the Mandatory Call Event and the call time, and the HKExH K E x suspends the trading of that CBBC on behalf of the issuer. There may be a possible time delay between the Mandatory Call Event and the suspension of the trading of the CBBC. In such case, any CBBC trades executed after the exact Mandatory Call Event time will be cancelled. We can only inform customers of the latest order status upon receipt of final confirmation from the HKExH K E x. The status of orders received after the Mandatory Call Event will thus change from “executed” to “unexecuted”. At the same time, for a CBBC buy order, the buying amount which is earmarked for settlement purpose will then be released immediately.

We can only inform you of the latest order status from “executed” to “unexecuted” upon receipt of final confirmation from the HKExH K E x. If you place your order through electronic channels such as internet and automated hotline, you MUST check your final status in Order Status through the specific electronic channels:

The receivable funds from the revoked CBBC sell order will be cancelled as well. In the event that there is any outstanding buy order using these receivable funds, you must settle any resulting overdraft in the settlement account with enough funds before T+plus2 to avoid unauthorized overdraft. The Bank reserves the right to sell the related securities to offset any unauthorized overdraft.

No. Only those quantities executed after the Mandatory Call Event time will be revoked. Quantities executed before the Mandatory Call Event time will be settled as usual on T+plus2.

The charges for trading CBBC is the same as that for local securities trading. Apart from the purchase amount, you may also need to pay brokerage fees and third-party transaction charges such as stamp duty, transaction levy, trading fee, etc. For details, please refer to the Securities Services Charges.
