btu: 1 of the "cheap" coal stocks?

There is an article on afr.com about undervalued coal stocks. I think BTU must get a mention as it came up from a search for BTU Unfortunately, I don't have a subscription so can't read it, but the byline says
'Fund managers and analysts are shouting ?buy? from the rooftops as coal companies tipped as M&A targets trade at extraordinary value.'

Don't know about you, but I think BTU can bounce hard even without the appeals being sorted. It's been beat up severely, but it could jump 20% pretty quickly IMO
