Domestic equities look to be good at the moment despite mixed cues from global markets, said Binod Modi Head-Strategy at Reliance Securities.

Concerns pertaining to increase in bond yields and higher commodity prices dented investors' sentiments in the last couple of days. However, the underlying strength of the economy and market remains intact in our view and hence any further correction in the market should be used to buy, he said.

He further added that Indian companies are likely to see sustained earnings recovery in subsequent fiscals and therefore premium valuations are likely to sustain.
