LAGOS — The Nigerian Exchange's Oil and Gas index rose 133.94 per cent in the first nine months of 2026, more than double the 61.43 per cent gain of the All-Share Index. Seplat rose 175 per cent and Aradel 128 per cent. Industrial goods gained 83.9 per cent and banking 78.9 per cent, while insurance was the only index to fall, down 8.6 per cent. Analysts linked the oil sector's performance to high crude prices and strong company earnings.
