Twitter Stock to Trade as NYSE: TWTR; IPO to Price Nov. 14

San Francisco-based Twitter Inc. (NYSE: TWTR) has found a new home on Wall Street: the Big Board.

"We intend to list the common stock on the New York Stock Exchange under the symbol TWTR," read Tuesday's amendment to the company's Form S-1 filing with the U.S. Securities and Exchange Commission.

Twitter's roadshow to meet with potential investors will take place from Oct. 28 to Nov. 6. The stock is expected to price Nov. 14 and begin trading on Nov. 15, CNBC reported.

The Twitter IPO is one of the most hotly anticipated initial public offerings of 2013 – but the company faces a number of obstacles.

A big one is that it continues to lose money. Just-released financials from the first half of the year indicate Twitter likely won't turn a profit in the second half, either.

Meanwhile, valuations for the company are running high, ranging from a lofty $12 billion up to a massive $25 billion.

That's one of the reasons Money Morning Chief Investment Strategist Keith Fitz-Gerald won't be investing in Twitter stock.

"That valuation is asinine for a company that hasn't showed any profit potential," Fitz-Gerald said. "Twitter Inc. may make a fine trading instrument, as long as the party continues. But as an investment? You can #countmeout."

Among highlights of the amended Twitter IPO filing, and why we here at Money Morning remain skeptical:

• The eight-year-old company reported its third-quarter loss more than tripled to $64.6 million from the same quarter a year ago, up from $2.6 million.

• While revenue rose from $205 million to $422 million over the first nine months of 2013 from the same period a year ago, its net loss surged to $134 million, up from $71 million.

• Revenue in Q3 2013 rose to $168.6 million, up from $82.3 million a year earlier. Yet compared to the second quarter, the revenue growth rate was roughly the same 105%.

• The company continues to book big increases in research and development (R&D), sales, and marketing expenses.
