Equity benchmark indices Sensex and Nifty faced heavy volatility on Thursday and ended lower, taking their losing streak to the fourth straight session, dragged by bank stocks and foreign fund outflows.

Concerns over fading rate cut hopes and persisting FII fund exodus from domestic equities also dampened investors' sentiment.

The 30-share BSE Sensex declined abruptly post noon, reflecting heavy fluctuations, wiping out all its early gains. It tanked 454.69 points or 0.62 per cent to settle at 72,488.99. During the day, it gyrated 1,107.38 points between the day's high and low.

The benchmark quoted 73,135.5 at 13:31 hours but within two minutes it declined to 72,817.03 at 13.34 hours, reflecting a drop of 318.47 points.

The NSE Nifty declined 152.05 points or 0.69 per cent to 21,995.85. It hit a high of 22,326.50 and a low of 21,961.70 during the day.

From the Sensex basket, Nestle declined the most by over 3 per cent amid reports that the global FMCG major sold infant milk products with more sugar content in less developed countries.

Titan Company, Axis Bank, NTPC, Tata Motors, ITC, Tech Mahindra, Bajaj Finserv, ICICI Bank, HDFC Bank and Bajaj Finance were the other laggards.

Bharti Airtel, Power Grid, Infosys and Larsen & Toubro were among the gainers.

"Domestic benchmarks extended losses amid mixed sentiments, emerged from escalating geopolitical tensions in the Middle East, and as hopes of US rate cuts waned. Meanwhile, investors will closely monitor the Q4 outcomes for further directions," said Vinod Nair, Head of Research, Geojit Financial Services.

In Asian markets, Seoul, Tokyo, Shanghai, and Hong Kong settled in the positive territory.

European markets were trading mostly with gains. Wall Street ended lower on Wednesday.

Global oil benchmark Brent crude declined 0.63 per cent to $86.74 a barrel.

Foreign Institutional Investors (FIIs) offloaded equities worth ₹4,468.09 crore on Tuesday, according to exchange data.

"Markets witnessed frenzied selling towards the closing stages in a highly volatile trading session, as concerns over fading rate cut hopes and persisting FII fund exodus from local stocks dampened investors' sentiment.

"Even as the Indian economy has been resilient and managed to dodge global worries, worries of stubborn inflation, rising instances of geopolitical tensions and delay in interest rate cut has fuelled profit-taking," said Prashanth Tapse, Senior VP (Research), Mehta Equities Ltd.

Stock markets were closed on Wednesday for Ram Navami.

The 30-share BSE benchmark tanked 456.10 points or 0.62 per cent to settle at 72,943.68 on Tuesday. The NSE Nifty declined 124.60 points or 0.56 per cent to finish at 22,147.90.
