Over on CAPS, fully 89 of the 97 All-Star members who have rated Gushan Environmental -- some 92% -- believe the stock will outperform the S&P 500 going forward. These All-Star bulls include madcowmonkey and TheHarm, both of whom are ranked in the top 16% of our community.

In April, madcowmonkey noted:

Biodiesel might be a speculative call in China, but the company's platform may change in the future with China being scrutanized of their polluting practices. Biodiesel has a future in China and I don't just believe [Gushan] will outperform the S&P, but will be a long term outperforming stock that some will wish they had chosen 5 yrs from now.

A more recent pitch from TheHarm last month shared that bullish sentiment, further emphasizing China's need to get clean:

China has pollution problems and this is one of the solutions (and the are no real clear competitors). This company's numbers are stellar and they have been expanding at a nice clip. I expect this trend not only to continue but to continue with additional fervor as this segment of the market continues to heat up. China will only increasingly become more and more aware of the fact that they need to clean up their environment and this company stands to benefit from that awareness. Also, take into account an emerging middle-class that wants to drive more and more, and bio-diesel becomes more and more of an answer.
