Provided by Dow Jones By Yifan Wang Hong Kong and China-listed solar-energy stocks rose sharply on Wednesday, extending the sector s momentum as investors bet on strong demand and favorable policies. Hong Kong-listed Flat Glass Group Co., one of the world s largest solar glass makers, jumped as much as 18%, while its peer Xinyi Solar Holdings Ltd. rose up to 9.3%. Both stocks have more than tripled so far this year. In the Chinese market, polysilicon suppliers led the sector s advance. Tongwei Co. shares rose up to 9.4% and LONGi Green Energy Technology Co. added as much as 6.4% to hit a new record. The upbeat trend came after Chinese authorities last week issued a draft regulation that would allow solar glass manufacturers to increase capacity free of restrictions.
