China-based solar stocks continued to rally on Wednesday.

A report on tickerspy.com, however, says analysts are mixed on the sector because while China's government will increase subsidies to the country's solar power industry, questions remain about whether demand is sufficient. An index of China solar stocks that tickerspy maintains was up 59% in the past month.
