HONG KONG -- China's official policy shows the desire to put an end to cutthroat price competition and overproduction, as a prolonged streak of producer price deflation haunts the world's second-largest economy. With hopes of potential reforms upcoming, stock prices of Chinese solar panel makers have been among the first to rally.

Shanghai-listed Tongwei jumped as much as 12% in the five trading days to Thursday afternoon. Shares of Sungrow Power Supply also jumped 8.2% in Shanghai. Hong Kong-listed GCL Technology Holdings was 16.5% higher over the same period.
