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 Commercial Vehicle Group (NASDAQ:CVGI) fell as much as 14.7% today after reporting earnings.

So what: Third-quarter revenue fell 8.2% to $187.9 million and the company swung to a loss of $7.3 million. Analysts were expecting an $0.08 profit per share; after reporting earnings of $1.07 per share a year ago, this was a big hit for investors.  

Now what: Management said that end markets were weak last quarter and are expected to struggle into next year. A consultant was also hired to help streamline the business, which isn't usually a good sign for a company. I'm definitely not buying in after this report and would wait until revenue and earnings begin growing to take a hard look at the stock.
