NEW YORK

Wall Street has a major craving for takeout.

Investors sent shares of GrubHub Inc. up more than 30 percent Friday in an initial public offering that gave the online food-ordering service a market capitalization of nearly $2.7 billion.

GrubHub was one of four companies to go public Friday in what has been a very hot IPO market, especially for businesses in the cloud software and biotech industries. There have been 71 IPOs priced so far this year, up 115 percent from the same time last year, according to IPO investment adviser and research company Renaissance Capital.

“Investors are looking for growth in a slow-growth economy,” says Kathleen Smith, a Renaissance Capital principal.

Smith said she is seeing signs of investors getting more cautious, though, after some hot debuts quickly cooled off. One such company is Castlight Health Inc. Shares of the cloud-based health care software company more than doubled on their first day of trading last month. But the stock is now down about 50 percent from the high of $41.95 that it reached during its March 14 debut.

Whether GrubHub can hold on to its gains remains to be seen.
