On CAPS, 47% of the 740 members who have rated RadioShack believe the stock will underperform the S&P 500 going forward. These bears include vaderblue and A6EIntruder.

Just last month, vaderblue summed up RadioShack's bleak situation:

Poorly managed here. This stock relies on holiday sales and have a hard time now competing with Walmart, Target, Best Buy. I see a strong decline unless they sell out and or reorganize quickly.

Over the past five years, in fact, RadioShack's top line has decreased at rate of 2.6% annually. Over the same time period, rivals Amazon, Best Buy, and Wal-Mart have grown their revenues at an annual rate of 33%, 10%, and 6%, respectively.

CAPS member A6EIntruder elaborates on the bull case:

What do you call a national chain of small electronics stores that once catered to the hobbyist set and a generation of tinkerers that is now best known for selling cell phones? One more hint: this company has virtually no moat!

Radio Shack, Radio Shack. How far you have fallen. Time was it was a respectable place where you could buy diodes, pick up programming on a TRS-80, and buy first-generation rechargeable batteries. You're but a shadow of your former self. Really, bud--take a look in the mirror! It's time to freshen up and greet the day!

I can't imagine how Radio Shack could be relevant to anyone. Its one advantage is the small store footprint, but how many cell phones in a near-saturated NA market do you have to sell before you're profitable? Honestly, selling cell phones out of those carts in the mall might be more lucrative.
