Over on CAPS, some 97% of the 806 members who have rated Gushan believe the stock will outperform the S&P 500 going forward. These bulls include noblepaladin and All-Star mrindependent, who is ranked in the top 4% of our community.

Late last month, noblepaladin tapped Gushan's current tax dispute as a compelling catalyst:

Large cash/share. Current quarter should be much better than last quarter since oil is up from its lows. There is a tax problem that is keeping the company down for now (whether biofuel should be taxed like normal fuel), but I believe it will be resolved in the favor of [Gushan]. Even if it is not in the favor of [Gushan], valuation alone should give [Gushan] limited downside as it is trading around liquidation value.

In a pitch from two weeks earlier, mrindependent shares that sentiment on the special situation:

The balance sheet is rock solid ... The company is waiting on a ruling as to whether the Chinese consumption tax applies to the product of one of its plants. If I were a Chinese official, I certainly would support alternative energy - considering commodities inflation is the leading threat to China's longterm growth prospects. Accordingly, I suspect that this company is in favor with the Chinese government. Last, but not least, I suspect this company's fortunes will wax and want with: (1) the Chinese market and (2) oil prices. I personally expect China to hold up better than the US stock market and I expect oil prices to remain fairly strong.
