Although we don't believe in timing the market or panicking over market movements, we do like to keep an eye on big changes -- just in case they're material to our investing thesis.
What: Shares of coal miner Patriot Coal (NYSE: PCX ) have fallen 10% today after a competitor announced another plant closure.
So what: Alpha Natural Resources (NYSE: ANR ) said it would close four mines that had become uneconomical. Falling coal prices and coal usage have caused companies to start closing plants that aren't cost-competitive, just as Patriot Coal did earlier this year.
Now what: You might think that less supply in the industry would be good for everyone, but what this really does is show just how dire the conditions are in coal. The low cost of natural gas has caused power generators to switch to natural gas, and more stringent regulations have caused older plants to close.
