India’s BSE Sensex gained about 0.2% to finish at 74,902.6 on Thursday, breaking a three-day decline as bargain hunters returned after the recent sell-off. Trading remained volatile near the close, with the expiry of key monthly derivative contracts and a new closing auction mechanism contributing to sharp swings. Investor sentiment stayed fragile because of concerns about surging oil prices and geopolitical uncertainty. Banking, power and selected heavyweight stocks advanced, offsetting losses in metals, pharmaceuticals and technology shares.
