Peabody Energy Group (BTU) was higher in the morning, but failed to hold the gains, closing 0.75% lower @ $27.09. There is a very viable large H/S formation that stretches from the low in late July. If there is renewed weakness in the main indexes in early 2013, then a break back <$20 seems likely.
BTU, daily
Summary
A break under rising support - into the $22s, would be the first major warning, and open up a test of the July $19 low.
There remains a distinct chance of a hit of the 2008 low, more likely in the latter half of next year. That of course would only occur if a broadly deflationary outcome occurred, and considering the printing of the central banks...that is somewhat hard to imagine.
BTU, as a company is one of the best coal miners out there...

On any basis, $15 would be appear a very good entry for long term buyers, although right now, that is some 40% lower from the current level.
