The Credit Lyonnais Shanghai B Index added 0.35 per cent, 2.21 points, to close at 629.12, pushed up by gains in stocks of No 2 Textile Machinery, Wing Sung and Tyre and Rubber. In the A market for domestic investors, trading was moderate. The Credit Lyonnais index ended down 1.92 per cent, just over 100 points, at 5,151.75. In Shenzhen, the B share market was active, with turnover of US$1.92 million. The biggest mover was China Bicycle, whose shares plunged 16.67 per cent to HK$7.5. The Credit Lyonnais Shenzhen B index lost 0.57 per cent, 4.61 points, to close at 810.61. The Credit Lyonnais Shenzhen A index was the day's worst loser, down by 2.4 per cent to end at 1,844.10. Bao Heng, a Shenzhen property development company, has delayed its B share issue due to the present weak market sentiment, but it will go ahead with its 67 million A share issue at 4.38 yuan a share, the company says.
