SHANGHAI B shares rose for the ninth time in 10 days on hopes that many listed companies would report good interim earnings, said traders. The Credit Lyonnais B-share index surged 48.40 points, or 5.84 per cent, to 876.94 points on turnover worth US$8.98 million. All 28 stocks rose. ''The interim earnings released so far have been good, and investors feel there is more to come,'' said Wendy Rong, a trader with Shanghai's Wangguo Securities. Several Shanghai companies reported strong earnings growth last week, pointing the way for other B shares, traders said. Real estate stocks Jinqiao and Outer Gaoqiao were the star performers, having seen their net profits for the first half of this year jump 120 per cent and 160 per cent respectively. Jinqiao gained 8.7 per cent to 87 cents on turnover worth $160,000. Outer Gaoqiao rose 4.8 per cent to 77.6 cents on turnover worth $1.9 million. China First Pencil jumped 7.7 per cent to 28 cents after reporting a 61 per cent jump in net profits for the first half, compared with the same period last year. ''Chinese investors gained some money from A shares last week and are now switching to B shares,'' said Julie Leung, an analyst with Sassoon Securities. ''Retail investors from within China were aggressively bidding up prices in the morning,'' said Samson Chau, a trader with Peregrine Brokerage. Chinese investors may trade B shares provided they have access to a foreign passport or can remit money from Hong Kong. Traders say mainland investors account for between 30 per cent and 50 per cent of B-share turnover. The B-share market looks strong, said Ms Rong, with several companies including glass manufacturer Yaohua Pilkington Glass and air-conditioner maker Shangling Electric Appliances Co expected to post good interims this week.
