TCS Q4 Preview: As the information technology (IT) services sector looks poised to continue with its trailblazing journey in the March quarter of the financial year 2020-2021 (Q4FY21), analysts expect the Tata Group crown jewel Tata Consultancy Services (TCS) to maintain its leadership position in the space in terms of revenue growth and margin expansion. TCS is expected to achieve this feat aided by certain large deals such as Postbank and Prudential Financial, ramp-up in multiple $50-100 million deals won in the preceding quarter, and strong demand in areas of cloud and customer experience. Hopes of a strong quarterly performance were visible in the stock price movement. The scrip jumped 11 per cent for the three months ended March 2021 and has risen nearly 16 per cent on a year-to-date (YTD) basis. This is against a 5 per cent rise in Nifty50 and a gain of 6.61 per cent in the Nifty IT index during the March quarter.
