"Tweeter is a bankrupt company and penny stock. On average about 29,000 shares of the company trade daily — minuscule by Wall Street standards. Its shares trade under the TWTRQ symbol.
But on Friday, after Twitter released its securities filing, some 14.4 million Tweeter shares traded hands, with prices peaking at 15 cents each before declining to 5 cents at the time of the trading halt. The previous day the stock had closed at one red cent per share."
