Equity benchmark Sensex soared 689 points to end at a fresh all-time high on Friday, led by Infosys, TCS and Reliance amid strong buying sentiment in global equities.

According to Binod Modi, Head-Strategy at Reliance Securities, growing expectations of stronger fiscal stimulus in the US after Congress confirmed President-elect Joe Biden's victory have fuelled equities rally globally.

"Markets completely downplayed earlier concerns of reversal of lower tax rates in the scenario of Democrats taking control of both the houses of Congress," he added.

A sustained rebound in key economic data for December 2020 and likely commencement of vaccination drive shortly in India augur well for domestic equities, he said, adding that the underlying strength of domestic equities is intact, which essentially can propel benchmark indices to witness fresh highs in coming weeks.

"FPIs are unlikely to turn net sellers barring select weeks of days considering the status of the global economy, stance of global central bankers and a weak dollar," he stated.

Stock exchanges in Europe were also trading on a positive note in early deals.
