India’s BSE Sensex fell about 0.2% to 77,234 on Tuesday, extending the previous session’s losses as geopolitical tensions in the Middle East, rising crude oil prices and caution ahead of the Nifty 50 monthly derivatives expiry pressured equities. The Nifty 50 also slipped, with 14 of 16 major sectors trading lower. Markets anticipated greater volatility because Tuesday was the first monthly Nifty derivatives expiry under the new closing-auction system. Global sentiment was subdued ahead of Nvidia’s earnings and amid renewed tensions between the United States and Iran. Foreign portfolio investors bought more than $2.5 billion of Indian equities in August, helping offset some pressure from high oil prices and geopolitical uncertainty. Hindustan led losses with a 6.7% decline, followed by IIFL Finance at 3.1%, Netweb at 3.0% and TCS at 0.8%.
