Domestic equities look to be flat for the day, said Binod Modi Head-Strategy at Reliance Securities.
According to him, a visible decline in daily caseload has offered comfort to investors, which indicates that earlier assumption of daily caseload in second wave peaking-out by the end of May or mid of June holds true and adverse impact of second wave should not be felt beyond 1QFY22.
"Investors will continue to focus on the trajectory of daily caseload and vaccination ramp-up in the country in the near term," he said.
