India's BSE Sensex closed about 0.7% down at 83,576 on Friday, the lowest since November 10, extending losses for a fifth day. Persistent FII outflows, uncertainty surrounding US-India tariff negotiations and escalating geopolitical tensions continued to weigh. Investors grew concerned over a potential 500% tariff on countries like India, a major buyer of Russian oil, while awaiting the US Supreme Court’s ruling on Trump-era tariffs. On the macro front, attention turned to the upcoming US jobs report and the release of domestic December inflation data, due next Monday, which is seen rising to 1.5%. Oil and gas stocks were the biggest losers, along with financials, autos, and metals. NTPC (-2.4%), Adani Ports (-2.2%), ICICI Bank (-2.1%), and Bharti Airtel (-1.7%) led the declines, while the IT sector advanced on optimism ahead of TCS and HCL Tech earnings on Monday. For the week, the index shed 2.5%, marking the first weekly fall in three weeks and the worst performance since September.
