Nigeria’s stock market may be experiencing a correction, but investors who positioned themselves in the right sectors have continued to enjoy substantial gains. Data from the Nigerian Exchange (NGX) shows that the All-Share Index (ASI) has delivered a year-to-date return of 51.62% as of June 19, 2026, even after shedding more than 16,500 points from its record high reached in May. However, beneath the impressive headline figure lies a much bigger story of sectoral winners and losers, with Oil & Gas emerging as the undisputed champion of wealth creation.
Leading the pack is the NGX Oil & Gas Index, which has surged an extraordinary 111.13% this year, more than double the broader market’s return. The remarkable performance has largely been driven by Aradel Holdings and Seplat Energy, whose share prices have soared by 161% and 95.6%, respectively. Industrial Goods followed closely with a strong 95.79% gain, benefiting from increased infrastructure spending expectations and improving manufacturing conditions. The Premium Board Index and Lotus II Index also delivered impressive returns, highlighting investors’ growing preference for fundamentally strong and quality-listed companies.
The oil sector’s outstanding performance has been highly concentrated among a few major players. Aradel Holdings has been the star performer, rising from N670 at the beginning of the year to N1,750 per share, while Seplat Energy nearly doubled in value over the same period. Other oil stocks, including Oando, Conoil, and Eterna Oil, posted moderate gains, though Geregu Power stood out as the sector’s only significant underperformer after recording a double-digit decline. Overall, an investor who evenly distributed funds across the six major oil and gas stocks at the start of 2026 would have achieved an average return of nearly 47% by mid-year.
While energy and industrial stocks generated exceptional returns, traditionally dominant sectors such as banking and consumer goods failed to keep pace with the broader market. The NGX Banking Index rose 35.77%, significantly below the benchmark despite strong earnings from major lenders. Analysts attribute the underperformance to elevated valuations, profit-taking activities, and concerns surrounding the Central Bank of Nigeria’s evolving regulatory policies. Consumer goods companies faced even greater challenges, with rising production costs, shrinking profit margins, and weakened consumer spending limiting the sector’s return to just 18.14%.
Insurance stocks delivered the weakest performance of all major sectors, declining 1.75% year-to-date and becoming the only productive-sector index in negative territory. Persistent capital adequacy concerns, low insurance penetration, and the ongoing adjustment to IFRS 17 reporting standards have continued to discourage investor participation. As the first half of 2026 draws to a close, market watchers are closely monitoring whether the dominance of Oil & Gas and Industrial Goods can be sustained or if the recent market correction will trigger a rotation of capital into undervalued sectors. The answer could shape investment strategies for the remainder of the year.
