Infosys and other Indian IT shares fell on Monday as investors booked profits after last week’s 4.3% sector rally, spurred by Infosys’ record Rs 18,000 crore buyback. Rising caution ahead of the US Federal Reserve’s policy meeting also weighed on sentiment. The Nifty IT index declined 1%, with Infosys slipping 1.6% to Rs 1,501.40.
