There are a lot of smiling people considerably richer than they were 24 hours ago, as Twitter’s  debut on the New York Stock Exchange shattered expectation, with the stock closing up 72%  at the end of trade.

With an initial public offering set at $26US, frenzied early trading saw the stock peak at $50US at one stage, before settling to end the day at $44.90US.

While there was caution in the lead up to the IPO – with many technology and finance professionals doubting Twitter’s business model, concerned that ad revenue from paid and promoted tweets would be insufficient to sustain and grow the business – it seems everyone was keen to get their hands on Twitter stock.

While the long term viability of a profitable Twitter remains unclear, it seems that in the short term at least, investors are prepared to put their money where their tweets are.
