On CAPS, 53% of the 640 members who have rated RadioShack believe the stock will underperform the S&P 500 going forward. These bears include All-Star minnjim1, who is ranked in the top 15% of our community, and mfoDon.

Just two months ago, minnjim1 touched on RadioShack's disappointing track record:

Radio Shack's management has been spectacularly unable to achieve success during three decades of massive electronics gadget, computer and internet revolution. With all that going on in the market, they have just barely been able to hang on. I will miss them when they depart the malls and strip malls of America.

Fools remain skeptical about how RadioShack can differentiate itself in the increasingly competitive consumer electronics space. Over the past five years, RadioShack's bottom line has steadily declined (-8.3% per annum), while electronics stores Best Buy (5.6%) and hhgregg (NYSE: HGG) (9.9%), online players like Amazon (17.2%), and even discounting foes such as Wal-Mart (6.5%) and Costco (Nasdaq: COST) (4.4%), have all managed to show positive earnings growth.

CAPS member mfoDon elaborates on the bear case:

When was the last time you actually went inside a Radio Shack? Yeah. Me too. Perhaps a merger would bump the stock but, really, what would a buyer be getting? Small footprint stores in malls that already have cheaper rents and include custom build-out for new lessees? Hard to see the 'Shack as anything but another icon slowing becoming as relevant as vinyl and CDs.
