The combined market capitalization of four of India's top ten most valued firms decreased by ₹1 lakh crore last week, with the State Bank of India (SBI) suffering the largest drop of ₹44,722.34 crore, bringing its valuation to ₹9,41,107.62 crore. Other firms such as Bharti Airtel and Tata Consultancy Services (TCS) also saw significant losses, with valuations dropping by ₹31,167.1 crore and ₹28,456.26 crore, respectively. Despite a rise in the BSE Sensex by 414.69 points (0.53%) and NSE Nifty by 178.6 points (0.74%), market sentiment remained cautious due to renewed geopolitical tensions, particularly between the United States and Iran. On the other hand, firms like Reliance Industries and HDFC Bank recorded gains, with Reliance's market cap increasing by ₹6,563.28 crore to reach ₹19,42,866.58 crore. This mixed performance highlights the volatility in the Indian equity markets amidst fluctuating global conditions.
