Hong Kong Exchanges and Clearing, which operates the local stock and futures markets, is expected to report a decline of up to 20 per cent in net profit last year as a result of lower market turnover and fewer initial public offerings (IPOs).

Analysts estimated profit could drop 12 to 20 per cent to between HK$ 4 billion and HK$ 4.5 billion in the year to December.

Announcement of the results is due on Wednesday.
