Some confused investors sent Tweeter's stock up as much as 1,400 percent on Friday. And trading volume skyrocketed to 14.4 million shares. Over the past year, the daily average was about 29,000, according to FactSet.
The Financial Industry Regulatory Authority, Wall Street's industry regulator, halted trading of Tweeter's stock Friday afternoon. The over-the-counter stock resumed trading with its new stock symbol Tuesday.
Tweeter's stock is down 76 percent to 1 cent in afternoon trading. It closed at 1 cent on Thursday before the mix-up and jumped as high as 15 cents on Friday.
Twitter's stock, meanwhile, won't be available for trading until the social media company actually goes public. That could be before Thanksgiving.
Anticipation around Twitter's IPO is high among investors after Facebook Inc. went public in May 2012. San Francisco-based Twitter has about 218 million users, far fewer than Facebook, which has more than 1 billion. But celebrities, from Oprah Winfrey to Justin Bieber, are on it. And many TV networks and news organizations encourage their viewers and readers to follow their Twitter pages.
Tweeter, meanwhile, was founded in 1972. The Canton, Mass., chain had sold TVs, audio equipment and other electronics, but the stores disappeared years ago. The company filed for bankruptcy protection in 2007 and closed the stores in 2008.
