Sourcefire Glows on Debut

In its first day of trading as a public company, Sourcefire Inc. (Nasdaq: FIRE) shares opened at $15 -- higher than initial estimates -- and peaking at $16.45 before they closed at $15.49. (See Sourcefire Fires Up for IPO and Sourcefire Shapes Up for IPO.)

And for its trouble, the open-source security vendor raised $89.4 million today, well above its estimate of $80.8 million.

Trading under the symbol "FIRE," the company originally priced its 5,770,000 shares between $12 and $14, although these were over-subscribed in the run-up to today's IPO.
