As usual Infosys will set the tone for IT firms when it announces Q2 numbers on Monday. Analysts expect Infosys to report a 2.5-3 per cent q-o-q growth in profits and around 5 per cent revenue growth in rupee terms. Fall of the rupee by about 2 per cent is expected to boost margins, analysts feel. Though most analsyts do not expect any change in guidance for the current fiscal, any positive surprise will boost the stock instantly.
