Groupon takes a major hit

Groupon takes a major hit

A broader market downturn has hit tech stocks this week, but newly public startups like Groupon were hit especially hard. Some economists say this could indicate renewed dot-com bubble concerns.

Groupon shares plunged 10% on Monday and were down another 12% midday Tuesday to trade at $20.61. That's mere pennies above the $20 price of Groupon's initial public offering earlier this month.
This year has been chock-full of Internet IPOs, and their typically large early gains have led to concerns about overvaluation.
Shares of business networking site LinkedIn were trading 7% lower for much of the session on Monday, the first day that some company insiders were allowed to dump the stock.
That phenomenon isn't exclusive to LinkedIn. It's typical for IPOs to include 180-day "lockup" agreements that prevent certain early investors from unloading their stakes.
Groupon's own lockup period ends May 2. Internet radio company Pandora's ends on December 12, and real estate Zillow's expires January 16.
