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: Darling International (NYSE: DAR) shares were all over the place today after the company reported earnings.

So what: Revenue for the third quarter was $168.7 million, and net income fell to $11.4 million, or $0.14 per share, both below expectations. After falling 10% to open the session, the stock recovered and is now trading higher.

Now what: I'm never excited about an earnings miss, and this is the fourth quarter in a row Darling International has missed estimates. The hot weather that affected material quality will improve, but I don't like the deteriorating profit at Darling, which recycles food waste. I'm staying away, especially after the rally later in the day.
