Coal shares fall as Alpha, Walter cut outlooks

Coal miner Alpha Natural Resources Inc (ANR.N) cut its 2011 shipment forecast, citing reduced demand from the key Asian steel market among other things, sending its shares down 10 percent and dragging down the whole sector. The news came as another major coal producer, Walter Energy (WLT.N) (WLT.TO), lowered its sales forecast for the second half of this year, because of weather and problems at some of its mines. Walter's stock dropped 10.1 percent to $67.42 and Alpha shares were down 12.1 percent at $23.65 on Wednesday afternoon on the New York Stock Exchange. Arch Coal (ACI.N) shares were down 8.8 percent at $16.44 and Peabody Energy (BTU.N) stock was down 4.6 percent at $40.91.

But even as US stocks fell nearly 3 percent and other commodities tumbled, gold came under renewed pressure as two weeks of extreme volatility for bullion rattled some confidence in its bull run -- despite the prospect of a second recession.
