HONG KONG (Nikkei Markets) -- Hong Kong shares retreated Tuesday morning, dragged down by losses among financial heavyweights.
The Hang Seng Index was down 0.6% at 30,601.31 at noon after rising 0.7% on Monday. Insurer AIA Group had slid 1.2% by the lunch break, the biggest drag on the gauge by points. On Monday, the company named Daisuke Iwase as group chief digital officer with effect from July 1.
London-headquartered lender HSBC Holdings and China Construction Bank (CCB) fell 0.7% each. Ping An Insurance Group shed 1.1%, putting it among the top five biggest contributors to the Hang Seng's losses.
Hang Lung Properties declined 1.5% after a subsidiary made a successful 10.73 billion yuan ($1.67 billion) bid for land use rights in Hangzhou, China. Guotai Junan Securities said the estimated 4.6% gross rental yield of the project meant the site was fairly priced but added that it was "definitely not cheap."
The Hang Seng has alternated between gains and losses over the last five days as ongoing trade tensions between the world's largest economies and uncertainty related to the U.S.-North Korea summit have made investors cautious. The index is down 0.8% in May so far, despite rising as much as 2.5% at one point from April's close.
Jason Lee, vice president for stocks at Hong Kong investment consultancy Investment Strategy Institute, said the index has lost momentum recently. "There are no new trading themes, only old themes like education, medical stocks and sporadic themes such as Alibaba affiliates," he said. "The market has been silent, as MSCI's inclusion of A-shares [on June 1] will put weight dilution pressure on other heavyweights and H-shares."
Lee expects the Hang Seng to trade between 30,500 and 31,000 points in the short term. "I think market momentum will improve a bit after early June," he said.
The Nikkei Asia300 Index was down 0.4% on Tuesday while the Shanghai Composite shed 0.6%.
