Idiots Send Stock Soaring

The hottest stock on the markets today is Tweeter Home Entertainment, a bankrupt chain of consumer electronics stores that trades on the pink sheets under the ticker TWTRQ.
The stock closed yesterday at less than a penny a share, and hit a high around 13 cents this morning.
The pop in the stock is happening because of confusion with Twitter which will trade under the ticker TWTR.
I don't know how anyone could think that a stock could take preliminary steps to file for an IPO on Thursday and be trading on Friday, but at least a few people made that mistake, it seems, and once they did, the stock got attention, maybe from computers, which triggered more buying, which triggered even more buying.
But once the mistake was revealed the stock didn't crater to its previous level, instead it kept trading all day at at least 500% than yesterday's close.
