SHENZHEN B shares closed flat yesterday on very low volume, with attention focused on Shanghai, brokers said. ''The Shenzhen market just doesn't have the same appeal,'' said SBCI Finance Asia. The B share index added 0.194 point to 105.207. Two stocks closed lower, one up and the rest were either unchanged or untraded. The one stock to rise was television and consumer electronics manufacturer Konka, which added 40 cents or 5.3 per cent to $7.90 on a volume of just 14,000 shares. Taiwan-funded toymaker Tsann Kuen was the day's most active stock, losing 10 cents to $4.50. A Hong Kong newspaper report that Japanese retail investors might soon be given access to the Shenzhen market failed to inspire trading. ''Even if Japanese investors are given the go-ahead, it will be at least two months before funds enter the market,'' SBCI said.
