Indian shares are expected to open higher following better-than-expected quarterly results from Tata Consultancy Services (TCS). The company reported a 9.7% rise in revenue and a 12.2% increase in net profit for the March quarter. However, concerns over the durability of a U.S.-Iran ceasefire may dampen risk. The Nifty 50 and Sensex have both gained 4.5% and 4.9% so far this week, putting them on track to break a six-week losing streak after the US and Iran agreed to a temporary two-week ceasefire.
