On CAPS, 31% of the 444 members who have rated Marriott believe the stock will underperform the S&P 500 going forward. These bears include JackCaps and kurtdabear.

Just last week, JackCaps offered two good reasons why investors need to check out of the stock: "Marriot has too much debt and too little operating income."

In a pitch from one month earlier, kurtdabear also explained why Marriott seems less than hospitable:

Regardless of how good a brand is, [Marriott] is in a business whose tide is going out -- and will stay out -- for years to come. Closing floors, laying off staff, etc., can cut costs short term in a business downturn, but it doesn't change fixed costs and debt service that were taken out in better times for a bigger business model.

What do you think about Marriott, or any other stock for that matter? If you want to retire rich, you need to protect your portfolio from any undue risk.
