India's BSE Sensex closed about 0.5% up at 84,363 on Monday, the highest since September 2024, extending gains for a fourth day, boosted by stronger-than-expected earnings and steady foreign inflows. Hopes of a de-escalation in US-China trade tensions and easing concerns over the US banking sector also provided support. Heavyweight Reliance Industries jumped over 3% to three-month highs after reporting a robust 14.3% year-on-year rise in consolidated net profit for the September quarter. Private and public sector lenders also reported a strong set of earnings over the weekend. Top private sector lender HDFC Bank on Saturday reported a 18% yoy jump in the net profit for the Q2FY26 quarter. ICICI Bank, however, fell 3.2% despite beating quarterly profit estimates due to concerns about soft loan and deposits growth. Domestic equity markets will be shut Tuesday and Wednesday for Diwali holidays, except for a one-hour Muhurat trading session on October 21.
