Seven of India’s top 10 most-valued listed firms lose a combined market capitalisation over one holiday-shortened week, with Reliance Industries taking the largest decline, according to multiple reports. During the period, the BSE Sensex falls about 0.7%–0.8% (639.61 points in one account) and the NSE Nifty declines around 0.7% (171.55 points in one account; other reports cite slightly different figures). Among the laggards, Reliance Industries’ market value drops by roughly ₹39,718 crore to ₹46,078 crore, depending on the source, leaving it around ₹17.5 lakh crore–₹17.87 lakh crore. Other firms reporting valuation erosion include HDFC Bank (down by about ₹33,333 crore in one report), Bharti Airtel, ICICI Bank, Tata Consultancy Services, Bajaj Finance and Hindustan Unilever. Meanwhile, some large caps gain during the same week, notably State Bank of India and LIC, as well as Larsen & Toubro in at least one account. Separate coverage also describes a different week where the top-10 firms collectively gain about ₹1.9 lakh crore, with ICICI Bank as the biggest gainer, underscoring week-to-week volatility.
