The combined market valuation of six of the top-10 most valued firms declined by ₹64,734.46 crore in a holiday-shortened last week, with Bharti Airtel taking the biggest hit, reflecting the broader weakness in the equities market.

Last week, the BSE benchmark Sensex declined 263.67 points, or 0.35%, and the NSE Nifty fell 106.5 points, or 0.46%.

“Markets ended lower for the sixth consecutive week, declining by nearly half a per cent, reflecting heightened volatility driven by a mix of global and domestic uncertainties.

“The holiday-shortened week began on a weak note as escalating US-Iran tensions and a sharp rise in crude oil prices weighed on sentiment, triggering broad-based selling pressure,” Ajit Mishra, SVP, Research, Religare Broking Ltd, said.

However, markets staged a mid-week recovery supported by easing geopolitical concerns and softer oil prices, he added.

“Despite this rebound, volatility remained elevated due to fluctuating global cues, continued foreign institutional outflows, rupee weakness, and inflation concerns, Mr. Mishra said.

The market valuation of Bharti Airtel eroded by ₹29,993.07 crore to ₹10,20,420.26 crore.

ICICI Bank’s valuation tanked by ₹12,845.81 crore to ₹8,70,705.49 crore.

Bajaj Finance lost ₹11,169.36 crore from its market valuation, which stood at 5,1₹4,226.12 crore.

The market capitalisation (mcap) of HDFC Bank dropped by ₹7,822.79 crore to ₹11,56,195.90 crore, and that of Hindustan Unilever’s mcap declined by ₹2,349.59 crore to ₹4,85,190.60 crore.

State Bank of India’s market capitalisation diminished by ₹553.84 crore to ₹9,41,015.31 crore.
