New Delhi: The key equity benchmarks, Sensex and Nifty, on Friday started trade on marginal gains in a volatile session tracking mixed global cues. However, the indices erased all gains and turned flat. 


At 10.15 am, the 30-share BSE Sensex was at 57,459, down 136 points, while the NSE Nifty declined 39 points to 17,183.


Among the Sensex platform, Bajaj twins, SBI, HDFC, Bharti Airtel, M&M, and Kotak Bank were the top gainers.


On the flipside, Titan, PowerGrid, Nestle, HDFC Bank, and Maruti were the top losers.


Midcap and smallcap shares were trading on a positive note as Nifty Midcap 100 index rose 0.37 per cent and smallcap shares surged 0.67 per cent.


Nine out of the 15 sector gauges, compiled by the National Stock Exchange, were trading in the negative zone. Nifty Consumer Durables and Bank were underperforming the index by falling as much as 0.87 per cent and 0.29 per cent, respectively. However, Nifty PSU Bank and Nifty Metal gained 0.49 per cent and 0.22 per cent, respectively.


Sectorally, Nifty Auto, Metals, PSBs, Realty and Oil & Gas were the notable gainers. While, Nifty Bank, IT, Pharma, and FMCG were subdued.


In the previous session on Thursday, Sensex had slipped 89 points to close at 57,596, while Nifty had moved 23 points lower to settle at 17,223.


On the other hand, Asian shares traded on a volatile note amid hawkish US monetary policy and ongoing fluctuations in commodity markets due to the conflict between Russia and Ukraine.


Stock exchanges in the US ended higher in the overnight session.

Meanwhile, international oil benchmark Brent crude surged 0.22 per cent to $119.29 per barrel. Crude oil eased as the US and allies considered releasing more oil from storage to cool markets. Brent crude fell 0.22 per cent to $118.77 per barrel and US crude was down 0.5 per cent to $111.74 a barrel, but prices were still very high by historic standards.


Foreign institutional investors (FIIs) turned net sellers in the capital market, as they sold shares worth Rs 1,740.71 crore on Thursday, according to stock exchange data.
