Domestic equities look to be modestly good as of now, said Binod Modi Head-Strategy at Reliance Securities.

Given the sharp improvement in key economic indicators like GST collection, auto sales volume despite supply disruption and other high frequency indicators like e-way bills in July indicate sustainable rebound in corporate earnings in subsequent quarters. This should aid the market to sustain premium valuations, he noted.

US equities ended mostly higher on Tuesday after the Senate passed a USD 1 trillion infrastructure bill.

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