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: Endeavour International (AMEX: END) shares fell 10% today after the company announced earnings.

So What: Net loss increased to $11.7 million from $4.5 million last year, partly thanks to the early termination of a derivatives contract. Discretionary cash flow in the quarter came in at $6.1 million compared to $7.6 million in the third quarter last year.

Now What: Yesterday, the energy company announced a 1-for-7 stock split to appeal to a wider array of investors and to keep from falling below the dreaded $1 mark again. Today's results weren't encouraging and investors have punished this volatile stock as a result. This Fool doesn't have the stomach to buy a volatile stock like this on a down day, so I'll wait for some good news before getting excited about Endeavour.
