Indian stock markets end the week lower, and the combined market valuation of the top 10 most valued companies declines by Rs 3.12 lakh crore. According to market reports, Reliance Industries records the largest loss among the group, while Bharti Airtel is the only company that gains. The decline comes as the BSE Sensex falls by 2,090.2 points (about 2.7%) and the NSE Nifty drops by 532.65 points (about 2.2%). Analysts attribute the sell-off to lingering geopolitical tensions in West Asia, persistent weakness in the rupee, and concerns about rising inflation. They also point to crude oil prices moving above USD 105 per barrel, which increases worries about imported inflation and potential pressure on corporate margins. Specific valuation changes cited include Reliance Industries, whose market capitalisation falls by about Rs 1.34 lakh crore, and State Bank of India, whose valuation declines by about Rs 52,245 crore. Overall, the sources describe a broad valuation erosion across large-cap companies during the week.
