A couple of days ago, my colleague Jeff Reeves took a look at 7-Eleven's decision to enter into the beer game. Yes, 7-Eleven -- the sultan of Slurpees, the high priest of week-old hot dogs, the convenience king -- is going to throw its proverbial hat in the ring, looking for your beer bucks.

I did not know this, but 7-Eleven is the third-largest beer retailer in the United States. Perhaps my ignorance is born from the fact that there are no 7-Elevens in my hometown.

Not all companies in these love-struck industries are good buys. Here are 10 stocks to break up with this Valentine's Day.

• 1-800-Flowers (FLWS): A good gift, but a poorly run company that has posted a loss for three of the past four quarters.
• Hershey (HSY): Missing out on the Cadbury merger was not so sweet for Hershey.
• Cardiac Sciences (CSCX): It's hard to have a heart for a company that fails seven out of my eight fundamental screens.

Where can you find the "Wall Street of the West?" In Colorado, of course -- specifically, Denver's 17th Street financial district.

Colorado's economy has come a long way from its foundation on trapping and mining. Denver's location, equidistant between Los Angeles and Chicago, between Seattle and New Orleans, has helped the Centennial State become the economic center of Rocky Mountain states -- even Denver's time zone and elevation help it keep in touch with the rest of the world. It's no wonder there's a large federal government presence in the state (U.S. Air Force Academy, NORAD, NOAA, Denver Mint, U.S. Geological Survey).

Companies such as Lockheed-Martin (NYSE: LMT), Qwest Communications (NYSE: Q), Comcast (NASDAQ: CMCSA), Molson Coors (NYSE: TAP), and Crocs (NASDAQ: CROX) offer a sense of the diversity of the state's economy. And so do the three companies examined here: Vail Resorts Inc. (NYSE: MTN), Dynamic Materials Corp. (NASDAQ: BOOM), and Newmont Mining Corp. (NYSE: NEM).
