Twitter Inc investors who heeded the advice of high-profile banks such as Goldman Sachs Group Inc and Deutsche Bank AG to buy the social media company's shares might be kicking themselves.
Much more accurate calls were made by Wells Fargo, Atlantic Equities and Macquarie Research, whose analysts advised clients to get out of the high-flying stock about the time it peaked in December.
On Wednesday the stock fell as low as $37.24, 50 percent below its peak of $74.73 the day after Christmas, wiping almost $18 billion off Twitter's market capitalization.
The downgrades, and the subsequent swoon by the stock, reflect concern about slowing growth in Twitter's user base and the company's ability to reverse the trend. Year-on-year growth in the number of Twitter users has fallen for five straight quarters, and the company said on Tuesday that its 255 million monthly users, on average, appeared to check the service less frequently than a year ago.
That in turn has fueled doubts that Twitter could one day attract as many users as Facebook Inc's 1.2 billion, or match its much larger rival's power as an advertising vehicle. It's also raised questions over whether it can sustain growth over the long term. While no one is suggesting Twitter will lose its consumer cachet as happened to companies such as MySpace or Orkut, neither can anyone guarantee that as tastes change newer rivals won't usurp it.
"Can they become a mainstream company? That's the open question," said Ben Schachter, the Macquarie Securities analyst who downgraded Twitter's stock to "underperform" on Dec. 27 - the day after it peaked.
It's a far cry from the enthusiasm that greeted the company when it debuted on the New York Stock Exchange on Nov. 7 and its shares soared 73 percent over the offering price. There was no let-up for the next two months, as the stock scaled fresh highs with little or no news to justify the valuation.
That got some analysts worried. Schachter, speaking to Reuters on Thursday, recalls a "runaway momentum."
Starting mid-December, seven brokerages downgraded the stock within a span of three weeks. Wells Fargo and SunTrust Robinson kicked off the first round of downgrades on Dec. 16, followed by Atlantic Equities. Macquarie timed its downgrade to perfection.
In his downgrade note on Dec. 16, Wells Fargo analyst Peter Stabler said investors were "underestimating the challenges facing the company".
A common theme was that Twitter, though innovative, well-run and full of potential, simply did not warrant such a rich valuation, so soon.
"They are focusing on the right things. I only have positive things to say about the company. My quibble is with the stock," said Brian Wieser, Pivotal Research Group analyst, who was among the first to urge clients to retreat.
He downgraded the stock to "sell" immediately after Twitter's shares jumped on its opening day. At the time, he had a $30 target price on the stock and recommended selling after they breached the $45 level in their market debut.
Twitter said in 2010 that it aims one day to have 1 billion users. It did not specify a time frame.
Some of the analysts who downgraded the stock in December are not as confident in Twitter's long-term outlook, much of which will hinge on the company's ability to increase both the number of users and how much time they spend on the site.
A fast-growing and engaged user base would help Twitter rake in more advertiser dollars; however, those are issues over which management has limited control, Atlantic Equities analyst James Cordwell said in December.
Investor worries were reflected in the response to Twitter's quarterly results this week, when the market overlooked higher-than-expected revenue to focus instead on the slow user and usage growth. Twitter's shares fell 10 percent.
The expiration on May 5 of Twitter's six-month "lockup" - the period after the initial public offering during which early investors are barred from selling their shares - could put the stock under more pressure. Restrictions on about 470 million shares will be removed.
Twitter's co-founders, Jack Dorsey and Evan Williams, and Chief Executive Richard Costolo have said they do not plan to sell their shares after the post-IPO restrictions are lifted.
Only one other major investor, Benchmark Capital Management Co LLC, which owns 31.6 million shares, has publicly stated that it will not sell the stock when the lock-up expires.
"Despite some key investor and executive statements that they will not sell near term, we estimate that 50-70 percent of shares could be unlocked," JPMorgan Chase & Co analyst Doug Anmuth said in a research note on April 30.
THE OTHER CAMP
Still, Goldman and Deutsche Bank, both underwriters of the high-profile IPO, maintain their positive views of the stock, in spite of the user trends, two consecutive quarters of disappointing results and the decline in its shares.
Twitter shares trade at 334.2 times forward earnings, far more than Facebook's 38.1 times, according to StarMine, or the average of 17.95 for the Standard & Poor's 500 Index, according to Thomson Reuters data.
"The company continues to execute near-flawlessly around items in its control like revenue and expenses," Deutsche Bank analyst Ross Sandler wrote in a note on Thursday, a day after Twitter posted its second-quarter results. Sandler didn't immediately return a phone call and an e-mail. Goldman Sachs analyst Heath Terry was traveling and not available for comment, his assistant said.
Sandler said market sentiment would eventually shift away from users toward revenue growth. Facebook, he argued, also struggled with slow user growth last year before regaining Wall Street's favor thanks to its strong mobile ad business.
Schachter, the Macquarie analyst, says much will depend on how successful Twitter will be in revamping its site to attract mainstream users.
"They are executing well in terms of innovation, but the user growth is a bit of a concern," he said. "The hope is that they can change the site, to make it more user-friendly."
