The 30-share BSE index ended 307.66 points or 0.60 per cent higher at 51,422.88. The broader NSE Nifty surged 97.80 points or 0.64 per cent to close at its fresh peak of 15,435.65.
Reliance Industries was the top gainer in the Sensex pack, soaring nearly 6 per cent, followed by M&M, HDFC twins, Kotak Bank, ITC and Bharti Airtel.
On the other hand, Sun Pharma, Bajaj Finserv, ICICI Bank and Dr Reddy’s were among the laggards.
“Domestic equities remained upbeat and recorded fresh high as improved prospects of economy recovery and strong 4QFY21 earnings continued to bolster investors’ sentiments. A strong rebound in Reliance Industries was a key driving force,” said Binod Modi, Head Strategy at Reliance Securities.
Sustained market rally added over Rs 3 trillion in investors’ wealth this week, with the market capitalisation of BSE-listed companies crossing the landmark USD 3 trillion during the week, he noted.
Further, a sharp drop in daily COVID-19 caseload in second wave (remaining below 2 lakhs despite higher testing) and improvement in recovery rates have emboldened investors in the last couple of days, he said.
