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: Well, they did it. After today's initial steep sell-off, the Dow Jones Industrial Average (INDEX: ^DJI) -- and other indices as well -- somehow managed to end the day in the green. But not everyone's smiling. Shareholders of DryShips (Nasdaq: DRYS), for one, may have dodged a bullet after pulling out of their 17% dive but still ended the day with a loss.

So what: Why is DryShips the odd man out? Why is it ever? Just like yesterday, the company remains tarred by its reputation as a "Greek shipper." (Greece, as you may have heard, is having some problems lately.) And as fellow Fool Anders Bylund pointed out yesterday, DryShips' venture into oil drilling with its drillships program is also hurting, as oil prices continue to sink.

Now what: Two months ago, I warned investors that DryShips' earnings weren't all they were cracked up to be, inasmuch as they lacked free cash flow to back them up. Two months later, we see this reflected in a P/E that's doubled even as earnings keep falling. With the company still burning cash, and with no end in sight, I see little reason for investors to board the stock today. Stay away.
