NEW YORK ( TheStreet) -- While recent technology initial public offerings enjoyed large pops on their first day of trading, these stocks have come crashing back to earth. Groupon ( GRPN), whose shares rose 40% on the company's first day of trading, has seen its fortunes largely reverse since then. Shares of the daily deal site closed Friday at $16.75, a decline of 36% since Groupon's IPO debut and well below its initial offer price of $20.
Other newly public tech companies also have seen sharp declines in their stock prices within the last two weeks, including LinkedIn ( LNKD) and Pandora ( P). This trend could have serious consequences for other tech companies looking to access the public markets this year, including Yelp, which recently filed a $100 million IPO, and Zynga. Forty-one tech companies have gone public so far this year, the most of any other industry, according to Renaissance Capital. But tech stocks have lost an average of 18%, making the sector among the worst performing. "The luster of going public is slowly wearing off now," said Scott Sweet, senior managing partner at IPO Boutique. But not all tech stocks have seen a significant drop this year. We take a look at several notable newly public tech companies, how they've performed and what analysts are expecting going into 2012.
