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 liquor distributor Central European Distribution (Nasdaq: CEDC) fell as much as 10% today.

So what: The market is again worried about Europe today after forgetting about it yesterday, and investors are now concerned about a possible downgrade of the company. Moody's placed its corporate family rating (CFR) and probability of default rating (PDR) under review for a possible downgrade.

Now what: The company's $1.3 billion in debt is a huge overhang, and after missing estimates the past three quarters, investors should be concerned. If rating agencies downgrade the company, borrowing costs can go up, making profitability even harder to come by. I would avoid this stock for now, considering the uncertainty in Europe and the heavy debt load on the balance sheet.
