Stock market ended the holiday-shortened week in red, dragging down the combined valuation of six of India’s ten most valued companies by Rs 64,734.46 crore, with Bharti Airtel emerging as the biggest loser. The broader market reflected the subdued sentiment, as the BSE Sensex slipped 263.67 points, or 0.35 per cent, while the NSE Nifty declined 106.5 points, or 0.46 per cent over the week.“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.He noted that sentiment improved briefly during the week. “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,” Mishra said.Among the major decliners, Bharti Airtel saw its valuation fall by Rs 29,993.07 crore to Rs 10,20,420.26 crore.
