India’s benchmark indices fell for the sixth consecutive session on Monday, as tensions in the Middle East and foreign institutional investor (FII) outflows weighed on investor confidence.

The Sensex dropped 638.45 points, or 0.78 percent, to close at 81,050, while the Nifty shed 218.80 points, or 0.87 percent, finishing at 24,795.80.

Despite opening higher, the market quickly reversed its gains in the early hours and experienced volatility throughout the day, ultimately closing near its lows.

Among the biggest decliners were shares of NTPC, Adani Ports, Adani Enterprises, SBI, and Coal India. Top gainers included ITC, Bharti Airtel, Trent, M&M, and Infosys.

All sectoral indices, except for IT – which rose 0.6 percent – ended lower. The PSU bank, healthcare, capital goods, realty, metal, power, oil and gas, media, and telecom sectors fell by 1-3 percent. The BSE Midcap index dropped 2 percent, while the Smallcap index fell over 3 percent.
