It is not.
Tweeter Home Entertainment (TWTRQ) was a consumer electronics retailer that sold TVs, car radios, home theater systems, and the like at more than 100 U.S. stores. In 2007 it filed for Chapter 11 bankruptcy protection and had its assets sold to a new owner, who also filed for Chapter 11 a year later.
So why did shares of Tweeter stock jump more than 1500% this morning?
hah who would not do their research and base buying this stock off of 5 similar ticker symbol letters?
