The combined market capitalization of seven of India's top 10 most-valued firms dropped by approximately 3.63 trillion rupees in the past week. Reliance Industries was the biggest laggard, losing over 1.58 trillion rupees. HDFC Bank, Bharti Airtel, TCS, Infosys, Bajaj Finance, and Larsen & Toubro also saw their market caps erode. This decline occurred amid a bearish equity market trend, influenced by renewed US tariff threats and geopolitical tensions. ICICI Bank, State Bank of India, and Hindustan Unilever were among the few gainers.
