I hold a bull CBBC linked to Stock X, with a call price of HK$50. The spot price of Stock X is now trading at HK$52. Will the issuer provide active quotes for this CBBC?

Issuers provide active quotes for bull CBBCs linked to stocks where the spot price of the underlying stock is above 2% of the call price.

Where the call price of a bull CBBC is HK$50, a spot price above HK$51 meets the percentage requirement for the bull CBBC. In this case, your CBBC should be eligible for active quotes (subject to it meeting the other criteria, such as the aggregate number outstanding in the market) since the spot price is above 2% of the call price. You should also note that the bull CBBC would be knocked out when the spot price reaches HK$50.
