Holland America Line

Maybe it's time for Carnival to beach its Costa brand. The cruise line suffered another ugly mishap this week when a fire aboard the Costa Allegra left the ship powerless on the Indian Ocean, stranding passengers for three days with no hot food, air conditioning or running water.

It's now been two weeks since the Costa Concordia accident off the Tuscan coast of Italy. That tragic event aside, cruising is still a remarkably safe vacation choice. What's probably not as safe is investing in Costa's parent Carnival.

There's never a dull moment on Wall Street, not even when most of us are distracted by imminent arrival of the holidays. Let's go over some of the items that will help shape the week that lies ahead.
