Late last month, epeon touched on several of Alliance Resource's positives:

It has a nice cashflow, long term contracts, and increasing production. What is not hard to like? It pays you a nice dividend while you hold it and it has been increasing the dividend.

Alliance Resource's robust three-year average return on capital of 19.3% even tops that of rivals Arch Coal (5.2%), CONSOL (13.4%), and Peabody (11.8%).

CAPS member secretbonus expands on the Alliance Resource outperform argument:

[E]ven if you add a carbon VAT tax to the coal business, which seems to be the major fear, I believe this company will still hang in. Coal demand is expected to grow substantially ... but even if this company has 0 growth and earns $7 per share ... 10 years worth of earnings is plenty. ... ROE, ROI, ROA is incredible meaning there likely is good management. On the upside if there is growth and no political intervention this is an incredible opportunity here.
