The Indian stock market experienced a significant downturn last week, with the combined market valuation of nine of the top-10 most valued firms witnessing a substantial loss of Rs 2.94 lakh crore. Tata Consultancy Services (TCS) bore the brunt of the bearish trend, as domestic equities took a severe hit. The Sensex and Nifty indices plummeted by over 2.5%, contributing to the widespread market erosion. While most companies in the top-10 ranking saw substantial valuation drops, Bharti Airtel emerged as the lone gainer in an otherwise grim week for investors.
