Hungry For Some Action Ahead Of Twitter's Open? Here Are Some Of The Best And Worst IPOs Of 2013... - Professional Diversity (NASDAQ:IPDN), Chipotle Mexican Grill (NYSE:CMG)

With U.S. stocks trading at all-time highs on the eve of what could be one of the more prominent public offerings of the last five years, IPO fever is spreading. Twitter

TWTR

is expected to begin trade sometime near the end of this week (likely Thursday) and talks of oversubscription in the issue are flying. Despite the bull market in U.S. stocks, IPOs for companies outside of the social-media space have not attracted much attention lately. That's a shame as a few initial public offerings seem to haven doing pretty well lately. Some of the best IPOs investors may not heard of include:

Xoom Corp. XOOM - The money-transfer company's stock went public on Feb. 15 with an initial offering at $16. On Monday, November 4th, shares were trading at $30.30 a share, an increase of nearly 50 percent. The stock has been as high as $35.08. XOOM's revenue has been growing all year -- rising from around $80 million in January to $112.25 in September.
Noodles & Company NDLS - Noodles shares premiered at $18 on June 18th and have recently traded at $44.58, up over 50 percent. Noodles has been compared to Chipotle Mexican Grill CMG.
Sprouts Farmers Market SFM - The stock went public at $35 on August 1st and traded at $46.66 on Monday. On October 18th, SFM shares traded as high as $48.10. Sprouts is a supermarket operator that aims to be a low cost alternative to Whole Foods Market WFM.

Here's three IPOs many investors probably wish they had never heard of:

ExOne XONE - This 3D-printer manufacturer has been on a roller coaster ride since its February 7th IPO. The company's stock premiered at $30 a share, rose to $75.67 on August 13th and fell to $42.60 on September 30th. The stock rose back to $53.35 as of Monday's trading session, a gain of a little over 75 percent in a few months followed by a loss of 40 percent. Obviously IPOs are not for the faint of heart.
KaloBios Pharmaceuticals KBIO - The shares of this maker of next-generation antibody drugs are rapidly moving towards penny-stock status. The stock premiered at $8 a share on January 31st and had fallen to $4.04 as of Monday, a loss of nearly 50 percent.
Professional Diversity Network IPDN - The Network premiered at around $8 on March 5 and was down to around $4.99 on Monday, a loss of a little over 40 percent. The idea here was to create a LinkedIn LNKD for minority groups. The company's revenue has fallen by nearly $1 million since January 2013.
