Tweeter, Twitter: It’s all in the name

This final note today, in which we learn exactly how important ticker symbols really are.

We told you yesterday that Twitter’s gonna trade under the symbol TWTR. Which makes sense.

TWTR, however, is not the same as TWTRQ, which is the ticker symbol for a defunct consumer electronics company called Tweeter Home Entertainment. (Q gets tacked on there when a company files for bankruptcy.)

So, why am I telling you that? Because today 5 million shares of TWTRQ changed hands. It closed up 684 percent, at just over a nickel a share.
