China shares were mixed last week, as turnover dwindled and investors waited on the sidelines ahead of the spate of the earnings results due out soon. Over the week the Shanghai B-Share Index finished 0.3 per cent up at 51.062 points, while the Shenzhen B-Share Index lost 1.3 per cent to 60.42 points. Edward Chan, research director at Standard Chartered Securities, said: 'The markets continued to trend sideways and the turnover was small. 'Investors do not yet see any benefits from the easing of austerity measures.' Many of the B-share companies announce their results over the next few weeks and most investors were staying away from the market ahead of that. Mr Chan said: 'This round of results will show how bad the performance has been, and until then investors will stay on the sidelines.' Brokers said concern about China-Taiwan tensions also played their part in keeping turnover depressed. The centre of attention last week was the slide of Guangdong Electric Power Development Co, which accounts for more than 10 per cent of the Shenzhen B-Share Index. The counter dropped 6.6 per cent to HK$4.20 on Wednesday, with 3.4 million shares traded. Joyce Leung Ho-kit, institutional trader at Sun Hung Kai Investment Services, said: 'The fundamentals have not changed, but there was a big seller and a big buyer.' 'Some people said investors were switching to the newcoming B share, Heilongjiang Electric, but I am not sure this is feasible.' Another broker said concern about an oversupply of electricity to Guangdong province was keeping investors nervous. Guangdong Electric shares have risen 16 per cent this year, after the company completed repair work to one of its plants at a lower-than-expected cost. Some Shanghai-listed B shares also had a rocky week. Shanghai Yaohua Pilkington Glass Co dropped 3.4 per cent to 96.6 US cents on Friday, amid concern about its forthcoming results. Shanghai Refrigerator Compressor performed better, gaining 4.76 per cent to 44 cents over the week. The company has said it planned to expand its joint venture with Hitachi. Brokers said B shares were likely to continue to trade sideways this week. Ms Leung said: 'It will probably remain flat, but there could be some follow through from improving sentiment in Hong Kong. 'As the China-Taiwan issue becomes clearer, we look forward to a better performance of the [Hang Seng Index], and that should boost B shares.'
