Strong gains in the broader market also helped the total market valuation of BSE-listed companies hit a record high of Rs 141 lakh crore.
Riding high on strong sentiment in the broader market, the market capitalisation (m-cap) of BSE-listed companies rose by Rs 1,96,629.16 crore to Rs 1,41,79,644 crore.
The 30-share index surged 435.16 points, or 1.33 per cent -- its biggest single session gain since May 25 when it had surged 448.39 points -- to close at a new peak of 33,042.50. The index touched its life high of 33,117.33 intra-day.
From the 30-share pack, 18 stocks ended with gains led by SBI, which surged 27.58 per cent, and ICICI Bank 14.69 per cent.
