The BSE Sensex experienced a highly volatile session on Friday, closing about 0.3% down at 77,378,9 and marking the third straight day of decreases. Market sentiment continued to be dented by concerns over anticipated weaker Q3 earnings, slowing growth and continued foreign investors outflows. Global uncertainty also contributed, particularly due to worries about the potential policy actions of US President-elect Donald Trump. Despite some support from the IT sector, the weak performance of financials and other heavyweight sectors dragged the markets lower. Shares of Tata Consultancy Services (TCS) rose 5.7%, making it the top performer, as investors reacted positively to its Q3 results and optimistic demand revival guidance. For the week, the Sensex lost approximately 2.3%, following two weeks of gains.
