New Delhi: The combined market valuation of four of the top-10 most valued firms jumped ₹1.43 lakh crore last week, with State Bank of India emerging as the biggest gainer.

Last week, the BSE benchmark Sensex climbed 404.53 points, or 0.51 per cent, and the NSE Nifty went up by 187.05 points, or 0.76 per cent.

"Markets ended the week with modest gains despite heightened volatility, as investors navigated the roll-out of the new Closing Auction Session (CAS) framework for F&O stocks, the Reserve Bank of India's monetary policy decision, and lingering geopolitical uncertainties," Ajit Mishra – SVP, Research, Religare Broking Ltd, said.
