According to V K Vijayakumar, Chief Investment Strategist at Geojit Financial Services, there are two macro numbers that will exert a big influence on the markets - externally, US inflation numbers; and internally, India's COVID data.
"The jury is still out on the US inflation with the Fed claiming that the spike in inflation in April is transitory and many economists and market experts believing that inflation will continue to rise to force the Fed to taper earlier than expected. We will have to wait to see how the inflation scenario plays out.
"The other number, India's COVID data, indicates steady improvement with fresh cases steadily declining and the latest number at 2.81 lakh is indeed very positive. And, the recovery numbers at 3.78 lakh indicate a steady decline in total caseload. This means the present increasing lockdowns will be a temporary phase which is likely to be ignored by the market," he said.
