India's top companies face sharp market cap decline amid uneven investor sentiment

Indian equities experienced a volatile week with the biggest loss-making sessions seen among Tata Consultancy Services and Reliance Industries, resulting in over ₹66,000 crore wiped off shareholder wealth despite some firms ending higher.

India’s equity markets ended a choppy week lower, with investors in several of the country’s largest listed groups taking a hit even as a handful of stocks delivered gains. According to reporting from Aaj Tak, the sharpest losses over the five trading sessions were concentrated in Tata Consultancy Services and Reliance Industries, which together wiped out more than ₹66,000 crore in shareholder wealth.

The weakness came against a broader backdrop of selling pressure in Indian equities. The BSE Sensex slipped 490 points over the week and closed on Friday at 78,009, while the NSE Nifty lost 205 points to finish at 24,366. Aaj Tak said the biggest drags on the indices included TCS, Reliance, HDFC Bank, ICICI Bank and State Bank of India.

TCS saw its market capitalisation fall to ₹8.53 lakh crore, erasing ₹34,263 crore in value for investors over the five sessions. Reliance suffered an even larger absolute loss, with its market value dropping to ₹17.70 lakh crore and shareholder wealth shrinking by ₹31,869 crore. The banking sector also came under pressure, with State Bank of India shedding ₹25,892 crore in market value, while HDFC Bank and ICICI Bank also declined.

Yet not every heavyweight moved lower. Aaj Tak reported that Life Insurance Corporation of India posted the strongest gain among the top 10 most-valued firms, adding ₹26,438.49 crore to investor wealth and lifting its market value to ₹5.23 lakh crore. Bharti Airtel, Bajaj Finance, Larsen & Toubro and Hindustan Unilever also ended the week higher, underscoring the uneven nature of the market slide.

Despite the setback, Reliance remained India’s most valuable listed company by market capitalisation, followed by Bharti Airtel, HDFC Bank, ICICI Bank, State Bank of India, TCS, Bajaj Finance, Larsen & Toubro, LIC and Hindustan Unilever. The latest moves fit a wider pattern seen in recent months: business publications have repeatedly reported large swings in the market values of India’s top companies as foreign investors sold shares and global and domestic sentiment shifted.
