On CAPS, 99% of the 341 members who have rated Longwei believe the stock will outperform the S&P 500 going forward. These bulls include staranalystkc and bokononblue22.

Just last month, staranalystkc listed several of Longwei's positives: "Very [robust] competitive advantages, stable, highly predictable, safe, and healthy profit margins, high short-term and long-term organic and external growth potential, and dirt [cheap], unduly discounted valuation level."

In fact, Longwei currently sports a paltry P/E of 3.7. That represents a clear discount to listed rivals Sinopec (8.4) and PetroChina (13.5), as well as other foreign energy plays like Petrobras (NYSE: PBR) (9.2)

CAPS member bokononblue22 elaborates on the bull case:

Very simple -- they're an energy distributor in China, supporting mainly commercial operations in a mountainous mining region. Energy prices will go up, demand for that energy will go home. Ergo, the business will go up. And those mountains, moats don't get much more imposing than that. They'll bar oil producers from building a pipeline to the region.
