"Barring financials, June quarter earnings so far have been encouraging and most companies succeeded to beat consensus estimates, which offered comfort and aided to restrict sharp fall despite selling pressure in global equities," said Binod Modi Head-Strategy at Reliance Securities.

Further, persistent soft monetary policy stance of Federal Reserve along with least possibility of any reversal of monthly bond buying in the near to medium term and recent softening of dollar index augur well for emerging markets including India, Modi added.

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

Meanwhile, international oil benchmark Brent crude declined 1.14 per cent to USD 74.55 per barrel.
