NEW YORK (AP) -- If Twitter's bankers and executives were hoping for a surge on the day of the stock's public debut, they got it. The stock opened at $45.10 a share on its first day of trading today, 73% above its initial offering price.
In what's expected to be a volatile day, the stock is now trading on the New York Stock Exchange under the symbol "TWTR." It's the most highly anticipated initial public stock offering since Facebook debuted last year.
The opening price values Twitter at $31 billion, which puts it in in range of KFC and Pizza Hut owner Yum! Brands, tractor and tool maker Deere & Co. and slightly below State Street Corp., a financial services holding company.
Earlier in the day, Twitter gave users the opportunity to ring NYSE's opening bell instead of executives. The users included Sir Patrick Stewart, Captain Jean-Luc Picard in Star Trek: The Next Generation, Vivienne Harr, a 9-year-old girl who ran a lemonade stand for a year to raise money to end child slavery, and Cheryl Fiandaca of the Boston Police Department.
Twitter's initial public offering, has been carefully orchestrated to avoid the glitches and eventual letdown that surrounded Facebook's initial public offering on the Nasdaq 18 months ago. Still, it's the most highly anticipated IPO since its Silicon Valley rival's 2012 debut.
On Wednesday, Twitter had set an IPO price of $26, which valued the company at more than $18 billion based on its outstanding stock, options and restricted stock expected to be available after the IPO. That already put it above Macy's and Bed Bath & Beyond. Facebook's value, meanwhile, stood at $104 billion at the time of its IPO.
Twitter, named after the sound of a chirping bird, got its start seven years ago, first with Jack Dorsey and then Evan Williams as CEO. Its current chief is Dick Costolo, a former Google executive who once aspired to be a stand-up comedian. On March 21, 2006, Dorsey posted the world's first tweet: "Just setting up my twttr." Noah Glass, who helped create Twitter, posted the same words just 10 minutes later.
Since then, the social network that lets users send short messages in 140-character bursts has attracted world leaders, religious icons and celebrities, along with CEOs, businesses and a slew of marketers and self-promoters.
Tempering expectations was a big theme in the weeks leading up to Twitter's IPO, but that all but flew out the window with the stock's opening surge.
The company tried to avoid the trouble that plagued Facebook's high-profile offering. Facebook's public debut was marred by technical glitches on the Nasdaq Stock Exchange. As a result, the Securities and Exchange Commission fined Nasdaq $10 million, the largest ever levied against an exchange. Those problems likely led Twitter to the NYSE.
Twitter is also likely hoping for a first-day pop of its shares that eluded Facebook's stock. Facebook's shares closed just $0.23 above their $38 IPO price on their first trading day. They traded below $38 for more than a year.
Still, $18 billion is a lofty valuation for Twitter compared with its peers. At its IPO price, Twitter is valued at roughly 28 times its projected 2013 revenue -- $650 million based on its current growth rate. In comparison, Facebook trades at about 16 times its projected 2013 revenue, according to analyst forecasts from FactSet. Google meanwhile, is trading at about 7 times its net revenue, the figure Wall Street follows that excludes ad commissions.
Research firm Outsell puts Twitter's fundamental value at about half of the IPO price, says analyst Ken Doctor. That figure is based on factors such as revenue and revenue growth.
"That's not unusual," Doctor says. "Especially for tech companies. You are betting on a big future."
One of Twitter's biggest challenges as a newly public company will be to generate more revenue outside the U.S. More than three-quarters of Twitter's 232 million users are outside the U.S. But only 26% of Twitter's revenue comes from abroad. The company has said that it plans to bring in more international revenue by hiring more sales representatives in countries such as Australia, Brazil and Ireland.
The pricing means Twitter raised $1.8 billion in the offering before expenses. Twitter was offering 70 million shares in the IPO, plus an option to buy another 10.5 million. If all shares are sold, the IPO will raise $2.09 billion, making it the biggest IPO for an Internet company since Facebook raised $16 billion last year.
Twitter, which has never turned a profit in seven years of existence, had originally set a price range of $17 to $20 per share for the IPO, but that was an obvious lowball designed to temper expectations. It was widely expected that the price range would go higher. Back in August, for example, the company priced some of its employee stock options at $20.62, based on an appraisal by an investment firm and it's unlikely to have lost value since.
Twitter's shares enter a frothy market. The Dow Jones Industrial Average closed at a record high on Wednesday, up 128 points, or 0.8%, to 15,746. The Standard & Poor's 500 index rose seven points, or 0.4%, to 1,770, just one point below its own all-time high.
