Infosys Technologies have raised revenue predictions to 6.6 percent from 5 percent prompting a share rise of over 15 percent.

The revenue prediction growth comes after expectations from analysts that Infosys would lower predictions.

Infosys posted a net profit of 23.69 billion rupees in the third quarter of the 2012-2013 fiscal year.

Rajiv Bansal, chief financial officer, Infosys, said: “We were able to maintain our margins through efficiency improvements despite increased operating expenses. We remain focused on making the right investments for profitable and sustainable growth in the longer term”.
