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 rare-earth miner Molycorp (OTC:MCPIQ) dropped as much as 16% today after reporting second-quarter earnings.

So what: Revenue rose 31% in the quarter to $136.9 million but net loss was $70.0 million, or $0.44 per share. Wall Street was expecting revenue of $157.6 million and a loss of just $0.23 per share versus a reported adjusted loss of $0.36.  

Now what: There's no improvement in sight for rare-earth element prices and that's the core problem for Molycorp right now. The company has flooded the market with supply and that's forced prices lower and profits have evaporated. I don't think any of the market pressures will ease and there's not a lot of hope for a profit going forward.
