Domestic equities continue to look good as of now, said Binod Modi Head-Strategy at Reliance Securities.
"Key economic indicators like GST collection, auto sales volume and other high-frequency indicators like e-way bills indicate a strong rebound in July, which bodes well and indicates sustained healthy corporate earnings in subsequent quarters," he noted.
Further, Modi added that India stands to be benefitted from China's regulatory crackdown on technology and education companies in recent weeks in the form of FIIs investments.
Elsewhere in Asia, bourses in Shanghai, Hong Kong and Seoul were trading with gains in mid-session deals, while Tokyo was in the red.
