What: Shares of Peabody Energy (NYSE:BTU) just can't seem to stop the bleeding, as shares declined another 18% in the month of November. Continued weakness in coal markets and a bloated balance sheet weigh heavily on the stock.

So What: The month of November didn't exactly start off on a bright note. At the end of October, the company posted a loss of $16.74 per share -- $8.13 per share excluding one-time items. It also lowered its 2015 guidance for coal volumes, with most of the cuts coming to its U.S. operations. Probably the more-important part of the company's lowered guidance was that the company's capital expenditures will be lower than originally expected. Considering that almost all of the company's operations are selling at a loss today, any way to preserve cash is critical.

Also, in an effort to raise cash and lower its liabilities, Peabody sold three mines to Bowie Resource Partners for $358 million in cash and the assumption of $105 million in debt -- although $105 million is a small drop in the bucket compared to the $6.3 billion in debt on the company's balance sheet.

Now What: The topic of climate change and environmental regulations has received a lot of attention from the coal space. Sure, these regulations could have an impact, but they are nothing in comparison to the fact that cheap natural gas is taking market share from coal in the electricity generation space, and forcing coal prices to such low levels that only a select few companies can wring out a profit.

As long as gas prices are cheap, coal will remain cheap, and it will continue to impact Peabody's bottom line. Without any price relief, it would not be surprising to see Peabody continue to see its shares slide like they have during the past several years.
