The teen market can be extremely difficult and competitive, especially with the fickle changes in tastes. But, rue21 has been able to beat the odds and as a result, has become a strong growth company.

To continue the momentum, rue21 launched its IPO today. The company issued 6.77 million shares at $19 each (the price range was $16 to $18). The lead underwriters included BofA Merrill Lynch (BAC), Goldman Sachs (GS) and J.P.Morgan (JPM).

Interestingly enough, rue21 has a spotty past. Keep in mind that in 2002 the company filed for bankruptcy. However, a new management team has certainly made the right moves to get things back on track.

With a name like rue21, the company must be cool, right? Well, it is. rue21 is a specialty apparel operator that is focused on the fickle young crowd -- that is, those between 11 and 17 who want to look "21." Or, for older people who want to feel "21."

Capitalizing on things, rue21 has filed to go public. And it should be a hot offering.
