Indian shares fell on Wednesday (16 May) as doubts over the composition of the next government in the southern state of Karnataka dampened investor risk appetite.
Prime Minister Narendra Modi's Bharatiya Janata Party (BJP) won 104 seats, falling marginally short of the 113 seats needed to form a government, while the opposition Congress clinched 78.
The Congress said it was ready to let regional party Janata Dal (Secular), which stood third with 37 seats, to form a government to stop the Hindu nationalist BJP from taking power.
However, analysts say the outcome of Karnataka's election results only strengthens the BJP's re-election prospects in 2019, something the markets will be optimistic about.
"Markets are at very high levels and hence very volatile, so every event will be met with overreaction," said Sudhakar Pattabiraman, head of research operations at William O'Neil's MarketSmith.
"Because of a few state elections coming up this year, expect markets to remain volatile but in the long term, things look extremely positive. There are strong indications that BJP will win the 2019 general elections."
