Equity benchmark Sensex rallied 487 points on Monday to close at a fresh lifetime peak, tracking gains in Infosys, HDFC twins and HCL Tech amid massive foreign fund inflows.

According to Binod Modi, Head-Strategy at Reliance Securities, domestic equities remained in the grip of bulls with benchmark indices registering fresh highs as robust earnings performance by TCS and D-Mart bolstered investors' confidence.

"Continued improvement in COVID-19 recovery rates and the announcement of the vaccination process from January 16 offered comfort to markets. Further, expectations of a sharp recovery in corporate earnings led by a sustained rebound in key economic data may propel the market to witness fresh highs in the near term," he stated.

FPI flow may continue to remain favourable given status of global economy, stance of global central bankers and weak dollar, he said, adding that domestic equities can also witness pre-Budget rally in the coming weeks considering broad expectations of pro-growth measures.

Foreign portfolio investors (FPIs) were net buyers in the capital market as they purchased shares worth Rs 6,029.83 crore on Friday, according to exchange data.
