Domestic stock markets soared on Monday with the Sensex gaining more than 1,400 points, a day after exit polls predicted that the Bharatiya Janata Party led National Democratic Alliance (NDA) will win almost as many seats as it did in 2014 and form a government comfortably. The S&P BSE Sensex surged as much as 1,405.89 points or 3.71 per cent to reclaim the 39,300 mark, and the NSE Nifty climbed 414.85 points from the previous close to hit an intraday high of 11,822.00. Advances in financials, auto, energy and metal stocks supported the strong up move in the equity markets. Analysts said the current rally could be short-lived before election results are declared on Thursday.
