I hold a bull CBBC linked to HSI expiring in 6 months and the entitlement ratio is 10,000. The bull CBBC was about 400 points to be knocked out. HSI index and futures both increased by 100 points but the bull CBBC only increased by HK$0.009.

This is because the delta of the bull CBBC is not exactly equal to 1. Besides, there are a number of different factors which may affect the price of a CBBC other than underlying spot such as expected dividend and funding cost.
