Shares in Sanlian Commerce, a Shanghai-listed consumer electronics store chain, rose by the 10 per cent daily limit yesterday after bigger rival Gome Electrical Appliances Holding became its largest shareholder. The investment spurred speculation the nation's largest consumer electronics retailer will buy out Sanlian, paving the way for a back-door listing by Gome in the A-share market. Sanlian, which has surged 73.17 per cent over the past year, closed 10.02 per cent up at 10.65 yuan (HK$11.68) after being suspended from February 14. Hong Kong-listed Gome rose 1.01 per cent to HK$17.92. Loss-making Sanlian Commerce told the Shanghai exchange a subsidiary of Gome agreed to pay 541.12 million yuan for a 10.69 per cent stake in the firm at an auction last month. Gome bought 27 million shares in Sanlian at 19.90 yuan each, a 105.6 per cent premium to the last closing price of 9.68 yuan before the suspension.
