Twitter shares have surged in morning trade after the messaging platform eased investor concerns with a quarterly report showing strong user growth and robust revenues.

In the first half hour of trading on Wednesday, Twitter rallied 20 per cent to $US46.15 ($A49.93), the highest levels since March.

Investors focused on the number of monthly active users hitting 271 million, up 24 per cent when compared with the same period a year earlier.

Revenues meanwhile leapt to $US312 million, and the market appeared the shrug off Twitter’s widening loss at $US145 million.

Youssef Squali at Cantor Fitzgerald called the financial results “very strong” and added that “what’s more important is that the drivers for this growth seem sustainable, implying faster-than-expected growth and margin over time.”

Ross Sandler, analyst at Deutsche Bank, said the quarterly figures appear to have calmed scepticism about Twitter.

He said that fundamentals for Twitter “are all trending in the right direction” and said the opportunity for the company is “under-appreciated.”

After Twitter’s successful public offering last year, the stock surged to over $70, but since then sceptics have wondered whether it can grow its user base and become profitable.

Daniel Ernst at Hudson Square Research nevertheless maintained his “sell” rating for Twitter, saying that “the platform is not likely as applicable to as broad an audience” as Facebook.

“While we see no obvious negative catalyst near term, expectations are rising and… Twitter in our view is grossly overvalued.”
