Sensex snapped its three-day winning streak on Friday as market heavyweight Tata Consultancy Services Ltd slumped on worries about its future following key management changes.
Shares of the IT outsourcing giant fell 4 percent to Rs 2,250 as CEO Natarajan Chandrasekaran's departure to head holding company Tata Sons as chairman overshadowed the company's better-than-expected December-quarter results.
Adding to the fall, Infosys shares declined on profit-taking after the company posted positive quarterly results, but narrowed its full-year revenue guidance range. The stock closed 2.74 percent lower at Rs 973.
Infosys fell as much as 3.73 percent to its lowest since December 7, coming off a two-and-a-half-month high touched earlier in the session.
Earlier in the day, the country's second biggest software services company posted a better-than-expected 7 percent rise in third-quarter profit.
"Market was overheated ahead of Tata Consultancy Services and Infosys Ltd reporting their results," said RK Gupta, managing director, Taurus Asset Management Company
"We can also see a bit of profit-booking as well as caution ahead of Donald Trump taking over the U.S. presidency."
