A weaker-than-expected quarterly profit from electronics bellwether Best Buy Co Inc led to a decline in shares across multiple platforms.

Smaller rival HHGregg Inc tumbled 9.1 percent to $22.39 while RadioShack dipped 3.6 percent to $18.52.

The retailer attributed tepid demand for televisions and entertainment hardware and software to its weakness in the domestic segment.

It's tapping the demand curve, said Cliff Draughn, President & Chief Investment Officer at Excelsia Investment Advisors in Savannah, Georgia.

The television that sold for $5,000 three years ago sells for $1,500 today -- how many people need four flat-screen televisions in their apartment?

Sony Corp , maker of the PlayStation game platform as well as flat-screen TVs, saw its U.S.-listed shares slip 0.6 percent to $35.66. Video game retailer GameStop Corp shed 0.9 percent to $21.72.

U.S.-listed shares of flat-screen maker LG Display Co Ltd lost nearly 1 percent to 18.10.

Corning Inc , which makes components for flat-screen televisions, also lost nearly 1 percent, to $19.11.
