Nine of the top 10 most valuable companies in India witnessed a collective market capitalization drop of Rs 2.94 lakh crore during the holiday-shortened week, with TCS and Reliance Industries facing the biggest declines. Bharti Airtel was the sole firm to show an increase in value. The bearish sentiment extended to the BSE Sensex and NSE Nifty, which both recorded notable decreases. This downward trend in market value reflects the challenging economic conditions faced by these leading Indian companies.
