SUNNYVALE -- Wall Street bought the Ruckus on Friday, as the Silicon Valley enterprise wireless dealer exercised an initial public offering that raked in $126 million at a valuation of $1.2 billion. When shares reached the floor of the New York Stock Exchange, investors were less kind, however, with shares plunging more than 18 percent.

Ruckus Wireless sold 8.4 million shares at $15 apiece, the top of the proposed price range, and began trading Friday morning under the ticker symbol "RKUS." After opening at the $15 IPO price, shares immediately dropped, trading in a range between $13.50 and $14.50 until a sharp drop at the end of the session left the stock at its lowest point of the day for the closing quote: $12.25, a drop of 18.3 percent.

Sam Hamadeh, CEO of analysis firm PrivCo, said Ruckus had priced the shares too high by aiming for the top of the range when $13 or $14 a share would have been welcomed more warmly.

"Ruckus Wireless overreached on pricing despite weak market conditions, and stock fell today due to mostly overall market conditions," Hamadeh wrote in an email.

Wall Street's weakness in the past two weeks, as a diminished European economy and the "fiscal cliff" debate in the United States make investors nervous, should have factored into Ruckus' pricing decision, offering a lesson to other companies looking to go public this year, Hamadeh said.

"Here, management did get too greedy, and it should be a lesson for private companies with IPOs in the pipeline: Best to leave a little money on the table and a positive narrative than have us now talking about a 'busted IPO' -- which Ruckus Wireless is," Hamadeh wrote.

The company sells advanced wireless equipment to mid- and large-size businesses, mostly focusing on Internet service providers. While battling with large companies that offer similar products along with their more natural offerings, such as networking giant Cisco (CSCO), Ruckus must also compete with similar companies like its Sunnyvale neighbor, Aruba Networks, which has a market cap of about $2.2 billion while trading on the Nasdaq.

Ruckus has managed to build strong financials despite the competition, boosting revenues 41 percent between 2009 and 2010, then another 26 percent in 2011, when the company produced a profit of $4 million. So far in 2012, that rate of growth has sped up, with the first nine months out of the year showing 93 percent revenue growth with net income nearing $30 million and a customer base of 16,000 companies and counting, a majority of them overseas.

The company's cofounders remain as executives, with Bill Kish serving as chief technical officer and Victor Shtrom acting as chief wireless architect while president and CEO Selina Lo runs the business. Lo has a history of developing startups, with her last effort, Alteon WebSystems, selling to Nortel for $7.8 billion.

The 10-year-old purveyor of "Smart Wi-Fi" products sold 7 million of the IPO shares -- the rest were sold by early investors -- to add more than $100 million to its company coffers. The company has 559 workers, according to its website, which manages to show the company's sense of humor as well, announcing the company's favorite holiday is "Festivus" and favorite food is chili cheese dogs. It has received nearly $73 million in venture capital from the likes of Sequoia Capital, Sutter Hill Ventures and Motorola Ventures.
