There's really only one word to describe what kind of year 2014 has been for Peabody Energy (NYSE:BTU) and its fellow coals stocks: rough. Shares of Peabody are down 23% this year, but, hey, at least it isn't on the list of worst performing energy stocks like Alpha Natural Resources (NASDAQOTH:ANRZQ).

Because of their dismal performance thus far, any news that isn't bad would be welcome. And this quarter there was a small sliver of hope in Peabody's earnings: the price for coal from the Powder River Basin. Since Peabody, Alpha, Arch Coal (NASDAQOTH:ACIIQ), and Cloud Peak Energy (NYSE:CLD)-- America's four largest coal producers -- all source a significant part of their coal from this basin, the price of Powder River Basin coal will have a significant role in all of these companies future.
