At the opening, Groupon shares sold at $28 per share, a 40% increase over the IPO price. The stock price peaked at $31.14 early, then dropped down to under $26 but is now trading at just under $29 (at 1:25 pm EDT).
In my view, the Groupon IPO is very welcomed. I'm hopeful that the stock price continues to perform well throughout the day and going forward, as it would be very good news for the IPO market overall, and especially for venture-backed companies waiting to go public. Venture Capital investors in Groupon include Accel Partners, Andreessen Horowitz, Battery Ventures, Greylock Partners, Kleiner Perkins Caufield & Byers, Maveron, New Enterprise Associates, Silver Lake Partners and Technology Crossover Ventures (TCV).
