Shares of China Unicom - the mainland's second-largest telecommunications operator - jumped yesterday after the company announced better-than-expected earnings in the year to December 31.
But the counter finished 10 HK cents lower at HK$8.55 on news its parent, China Unicom Group, was considering an issue of A shares.
The share price had improved by as much as 60 HK cents after China Unicom reported net profit last year surged more than threefold from a year earlier to 3.23 billion yuan (about HK$3.02 billion).
Analysts had forecast its earnings for the year at 1.58 billion yuan.
Chairman Yang Xianzu said the parent company was reviewing the feasibility of issuing A shares to help finance its 20 billion yuan code division multiple access network in the mainland.
Brokers said investors were worried that an A-share listing by the parent company could hurt expected asset-injections of China Unicom.
