According to Binod Modi, Head-Strategy at Reliance Securities, domestic equities continue to look steady and firm at the moment.

A sign of fatigue is visible in the benchmark indices for the last couple of trading days despite key economic data indicated a continued rebound in December 2020, he added.

Similarly, a sharp dip in FPIs net flows in recent days indicate a kind of profit booking and sector rotation given a sharp return generated by select sectors, Modi said.

Domestic markets are, however, following the global investor euphoria around American politics. US markets recorded fresh highs as investors continue to focus of stronger fiscal stimulus after Congress confirmed president elect Joe Biden's victory.

Elsewhere in Asia, bourses in Hong Kong, Tokyo and Seoul were trading with significant gains in mid-session deals, while Shanghai was in the red.
