Well, OK, we can't exactly call these stocks naughty. There are days when five-star winners and newsletter recommendations appear here. Today isn't one of those days.

But if you're an investor, you'll have plenty of bad days. The trick is to avoid dating -- or, worse, marrying -- your losers. That's why I listen when our 110,000-person-strong Motley Fool CAPS community of stock pickers speaks with a poor rating or a negative pitch. You should listen, too.

Thus, here is today's list of the worst stocks in the world.

We begin with Rockwell Automation, which reduced guidance. Management had projected between $4.25 and $4.45 in per-share earnings for the year. No longer.

Rockwell CEO Keith Nosbusch told investors that "market growth is slowing in two key regions," Forbes reports. I've no doubt that's true. What's troubling is that Rockwell had been on a great run. Return on invested capital has been rising steadily since 2001.

Wait for insiders to buy before betting on a turnaround here. They've dumped more than $10 million in shares since last June.

Next up is American Greetings, which reported a 56% decline in its fiscal first-quarter earnings. But you wouldn't know that from the comments CEO Zev Weiss made in a company statement: "I am pleased with our revenue performance, particularly given current economic conditions. Our point of sale performance is encouraging."

Revenue was up a breathtaking 2%. (My apologies for the sarcasm.)

CAPS investors have been expecting trouble like this. All-Star BiLoandWise wrote in May that American Greetings is a "long-term loser." And investor BalmInGilead said in December that "the greeting card will go the way of the telephone booth."

You can't question those calls so far.

But our winner is Monaco Coach, which fell 10% on high fuel prices and weak discretionary spending, the Associated Press is reporting.

Probably true. Gas now averages better than $4 per gallon across the country, and Monaco's 2009 LaPalma features a 75-gallon tank. That's at least $300 per fill-up for a monster that -- historically, at least -- doesn't average much more than 7 miles per gallon.

CAPS investor Seanonymous adds further perspective in this pitch from April:

I think it is too soon for a turnaround. I imagine people selling their big RVs for smaller ones and causing an over saturated market of new and used mobile homes that people don't want or can't afford. Short term this stock is bound to continue down through most of 2008.

Good points, all. Even Winnebago (NYSE:WGO) CEO Bob Olson says the market is too crowded and that a "discounting war" could break out. A price war? Now? That giant sucking sound you hear is shareholder equity being eaten by a vast and growing void.

Monaco Coach ... and Winnebago ... and Fleetwood Enterprises (NYSE:FLE) ... and, well, every other RV maker in the country right now -- Wednesday's worst stocks in the CAPS world.
