Reliance Industries, State Bank of India (SBI), ICICI Bank, and Larsen & Toubro contributed the most to the advances on Sensex on Thursday.

On Wednesday, the Sensex soared 1,014.75 points - or 2.59 per cent - to surpass its earlier all-time intraday high registered on Tuesday.

The Sensex had crossed the 30,000 mark for the first time in on March 4, 2015, but it took the benchmark index more than two years to take out that level on a closing basis.

On April 26, 2017, the Sensex settled at 30,133.35, in a first closing above the 30,000 mark.

Again, it took the BSE benchmark a little more than two years to complete the journey for the next 10,000 points.

Optimism on the election outcome triggered a rally in the markets late last week, which took a breather on Tuesday.

Some analysts had anticipated the rally ahead of election results to be short-lived.

The BJP has crossed the halfway mark on its own steam and leads showed an NDA sweep in the national elections within two hours of counting of votes.

Investors expect a second term will give PM Modi time to carry through those reforms while pushing for more fiscal and monetary stimulus.
