NEW YORK — A handful of young technology companies are expected to kick off the market for initial public offerings in the third quarter on a hopeful note.

Demand for IPOs was volatile during the second quarter as economic uncertainty weighed on stock markets, and numerous companies canceled IPOs or slashed prices. But a couple debuts had blowout first trading days, including options exchange CBOE Holdings Inc. and electric car maker Tesla Motors Inc.

This week’s new listings include private equity firm KKR & Co. LP, the parent of private equity firm Kohlberg Kravis Roberts, which launches Thursday on the New York Stock Exchange. It plans to register 204.9 million common units worth about $1.93 billion and said it may later raise about $500 million in a share offering.

KKR originally sought a U.S. listing in July 2007, hoping to raise as much as $1.25 billion, but it shelved those plans when the financial crisis hit.

Three young tech companies — long the IPO market’s mainstay — stand out among firms that plan to raise money this week:

  • RealD Inc., a California-based firm which supplies projectors for 3-D cinema screens and glasses for viewers;
  • SMART Technologies Inc., a Canadian company that makes interactive white boards; and
  • Qlik Technologies Inc., a Pennsylvania-based provider of business intelligence software;

"We’re very positive on Qlik and RealD," said Richard Schultz, president of Triad Securities, a brokerage firm in New York that tracks IPOs.

But it’s an IPO market "still in recovery," said PricewaterhouseCoopers’ Scott Gehsmann. With broad uncertainty about the strength of the economic rebound, it’s hard for companies with less name recognition than Tesla to take off in first-day trading.

During the second quarter, 17 companies canceled IPOs as the Standard & Poor’s 500 index dropped nearly 12 percent, and only 39 companies went public in the whole period, according to auditing firm PricewaterhouseCoopers. That may be 69 percent more than a year earlier, but it’s only half the number of companies that went public in the same period in 2007.

Still, there is hope in the backlog of companies waiting to go public. And if Qlik, RealD and SMART’s IPOs go well, "that’s more evidence that perhaps (IPOs) are coming into a better period," said Scott Sweet of IPOBoutique.
