Indian shares rose for a second session on Wednesday, with financials accounting for more than half the gains, as investors expect Prime Minister Narendra Modi to return to power after a national election.
Indian equities have been buoyant since last week over optimism Modi's return would spell stability and policy continuity.
"A higher probability of the current party coming back to power is something the market wants to play. The idea is that the rebound that we saw in 2014 (after Modi was elected) would replay," said Dhananjay Sinha, head-Institutional Research, Economist and Strategy at Emkay Global Financial Services.
"We'll have to see whether the same story can play with effectiveness."
India is set to hold a general election in two weeks and about 900 million citizens will be eligible to vote in the seven-stage exercise lasting over a month.
