Over on CAPS, 1,203 of the 1,250 members who have rated Arch -- or 96% -- believe the stock will outperform the S&P 500 going forward. These bulls include All-Star SuperPicks, who is ranked in the top 0.5% of our community, and FitzColinGerald.

Late last month, SuperPicks tapped Arch as a top opportunity: "Of the big coal plays, I like this one. It has been relatively conservative in the industry in recent years and pays a decent dividend. Today's levels appear quite cheap."

In a pitch from one week later, FitzColinGerald agrees with that bullish line of reasoning:

With the price of oil expected to rise once again in the next few years, coal will certainly be labeled as the most economical and practical alternative. Although adamant environmentalists need not apply, the coal mining industry has made vast gains with respect to environmental concerns. Arch Coal is definitely a leader in this field, as it seeks to mine coal for the purposes of electricity and steel production both domestically and internationally.
