SHANGHAI B shares rose in light trading as volume fell because of Hong Kong's Mid-Autumn Festival. The Credit Lyonnais Shanghai B Index rose 6.12 points, or 0.66 per cent, to 928.01 points on trading worth just US$2.24 million. The best performers were Friendship and Dajiang, which gained 5.6 per cent and 3.9 per cent respectively on light turnover. Pudong developer Outer Gaoqiao was again among the most favoured counters, being most active and picking up 2.8 per cent. The stock has been a consistent gainer in recent trading as investors see Pudong as a solid long-term opportunity. The A-share index continued its roller-coaster ride, surging 310.64 points, or 6.12 per cent, to close at 5,358.30 on what traders described as a major technical rebound after heavy losses in the past six trading days. 'Market sentiment is improved after the index overcame psychologically important points,' said Zhang Tao, a broker with Shanghai Shenying Securities. He said large counters, blue-chip Pudong shares and policy-sensitive Beijing companies led the rise, displaying strengthened confidence. 'The index is likely to further gain in the coming days because of today's breakthrough,' said Zhang Lei, a broker with Shanghai International Securities. Brokers said both institutions and individual investors were poised to build stocks today, especially in influential counters, after the index fell to threaten 5,000 at Tuesday's close.
