Twitter IPO: reaction round-up - Telegraph Wedbush analyst Michael Pachter told Market Watch he values Twitter at $37, but said valuation of Twitter is difficult because it is so early in its growth. He said Twitter has strong potential for revenue growth in the future and sees Twitter even surpassing Facebook. He said: "Because Twitter allows users to passively consume content, and does not require them to publish information about themselves, we think that Twitter's ultimate potential for users could exceed even Facebook's potential." Others believe Twitter priced the shares too low, and Ken Polcari, director of the NYSE floor division at O'Neil Securities, told Reuters: "In my mind they certainly could've raised the price on this thing and gone into the low 30s. From an outsider looking in I would say they were overly cautious because they didn't want a disaster on their hands ... I'm sure the company didn't want a Facebook debacle, I get that, but I think they were overly cautious and it cost them some money. Anthony Noto, the Goldman Sachs banker who led Twitter's initial public offering, simply tweeted "Phew!" as the $45.10 share price opened. The tweet suggests he was relieved that Twitter's IPO had made a stronger market debut than Facebook's in 2012, and that the share price was reasonable. Brian Weiser, Pivotal researcher, thinks TWTR shares should only be $30 not $45. He told Bloomberg: "For the $30 billion Twitter's valued for, you could buy the whole of Yahoo. BTIG research said there is a significant upside to investing in Twitter as it compared the company to Facebook. It showed Twitter's year-on-year revenue growth to be 72 per cent this year, compared to Facebook's 39 per cent. BTIG predicts the growth will fall to 60 per cent and then 52 per cent in the next two years, while Facebook's growth drops to 24 per cent by 2016. Gartner's Brian Blau told Cnet as long as Twitter's management can keep the company on the same path, it will continue to do well despite its continued losses. He said: "They have a strong and recognized global brand and they continue to do well with their advertising product. If Twitter can keep going down this track, and I believe they will, their post-IPO performance will be what investors are expecting. I don't get the sense there is a bubble right now. I mean, the level of investment is nowhere near the levels from the 2000 bubble. But Steve Rattner, financier and investment adviser, said the share prices suggest we are in a "tech bubble," as shares almost hit $50 and nearly doubled the IPO price of $26.
