India will announce the results of key state elections this weekend, in an important litmus test for the country's two major parties ahead of next year's general elections.
Exit polls indicate the main opposition Bharatiya Janata Party (BJP), led by Narendra Modi, performed strongly in the elections held in Chattisgarh, Madhya Pradesh, Rajasthan and Delhi. The official results of the elections, which were held between 11 November and 4 December, are due on 8 December.
"Results from exit poll surveys may differ from the official results, but the overall trend of BJP performing well seems consistent across exit polls," Nomura strategists wrote in a report on Thursday.
"From an economic perspective, the exit polls, as well as the final state election results, should impact sentiment positively," they added.
BJP is perceived as more business-friendly and willing to implement reforms compared with the ruling Congress party, which has been tainted by poor economic performance and slow pace of legislative changes.

The Congress party has led coalition governments at a national level in India since 2004, however its support base has been eroded in the recent years due to a string of corruption scandals and rising food prices, among other issues.
Delhi, which has traditionally seen a low voter turnout during state elections, witnessed the highest ever turnout, with the youth coming out in large numbers to cast their ballot for change.
Signs that the BJP is gaining traction have been welcome development by investors, with the rupee strengthening to a five-week high against the dollar, and Indian stocks rising to a one-month high this week.
"We've become pretty constructive on India and the rupee. I think the appointment of Rajan as the new RBI [Reserve Bank of India] governor was very significant. [And] you throw in the elections next year. For us it's a good story," Jonathan Webb, head of FX strategy at Jefferies Bache told CNBC's Capital Connection.
