Mumbai: Stockmarkets rose sharply on Monday, with Sensex closing higher by 676 points and Nifty climbing one per cent on heavy buying in auto and consumer durables stocks, buoyed by plans for big bang reforms in the GST regime by Diwali. The 30-share BSE Sensex jumped 676.09 points or 0.84 per cent to settle at 81,273.75. During the day, it zoomed by 1,168.11 points or 1.44 per cent to 81,765.77. The 50-share NSE Nifty climbed 245.65 points or 1 per cent to end at 24,876.95. Intra-day, it surged 390.7 points or 1.58 per cent to 25,022.

The global rating agency S&P’s upgrade of India’s sovereign credit rating, as well as US-Russia talks over the Ukraine war, also boosted market sentiment, analysts said. Among Sensex firms, Maruti zoomed the most by 8.94 per cent.

“The proposed rationalisation of GST is a sentiment booster for the domestic market. Additionally, the recent conclusion of the US and Russia summit, without any escalation in geopolitical tensions, has helped ease investor anxiety. The automobile sector outperformed, emerging as a key beneficiary of the anticipated tax reforms,” Vinod Nair, head (research), Geojit Investments Limited, said. The BSE smallcap gauge jumped 1.39 per cent while midcap index climbed 1 per cent.

“Markets staged a strong rally on Monday and ended with gains of over a per cent. The positive sentiment was driven by GST reform proposals, easing concerns over crude oil prices, and a sovereign rating upgrade, which together lifted investor confidence,” added Ajit Mishra, sr V-P (research), Religare Broking Ltd.

The BSE auto index jumped 4.26 per cent to 56,233.33. Hyundai Motor India jumped 8.45 per cent, Ashok Leyland by 8.12 per cent, TVS Motor by 6.58 per cent and Hero MotoCorp by 5.9 per cent.

Bajaj Finance rallied over five per cent, UltraTech Cement by 3.71 per cent, and Bajaj Finserv by 3.7 per cent. Mahindra & Mahindra, Hindustan Unilever and Trent were also among the gainers. However, ITC was the biggest loser, dropping by 1.26 per cent. Eternal, Tech Mahindra and Larsen & Toubro also declined. The Centre has proposed a 2-tier GST structure of 5 per cent and 18 per cent, besides a 40 per cent special rate on a select few items to the GoM on GST rate rationalisation. The proposal, which entails removing the current 12 per cent and 28 per cent tax slabs, will be discussed at the two-day meeting of the state ministerial panel on August 20 and 21 in the national capital, according to sources. Prime Minister Narendra Modi had announced the proposal to reform the GST law in his Independence Day speech on August 15 from the ramparts of the Red Fort.
