The Nigerian stock market navigated a volatile period in the first half of 2026, concluding the first six months with a robust year-to-date return of +51.62% for the All-Share Index (ASI). This performance, despite a significant rout in June that saw the market shed approximately 3.59% and N5.64 trillion in investor wealth during the week ended June 19, 2026, positions the Nigerian Exchange (NGX) among the stronger performing global exchanges for the year.
The market's peak year-to-date return reached about 60.9% in May, but a sharp correction in June erased previous gains, bringing the ASI down from its all-time high of 252,508 points to 235,941.27 points by June 19. Market capitalization also fell from N160.59 trillion at the end of May to N151.33 trillion by the close of the week of June 19.
The recent sell-off is attributed to a combination of profit-taking after an extraordinary rally, ongoing dividend season markdowns, half-year portfolio rebalancing by institutional investors, and potential liquidity raising for the Dangote Refinery private placement.
Sectoral Divergence and Top Performers
Beneath the benchmark ASI performance, significant divergence was observed across various sectors. The NGX Oil/Gas Index emerged as the standout performer, boasting a year-to-date return of +111.13% as of June 19, 2026. This exceptional growth was primarily fueled by Aradel Holdings Plc, which gained 161% year-to-date, and Seplat Energy Plc, up 95.6% year-to-date. Conoil Plc also contributed with a 12.2% gain.
The NGX Industrial Goods Index followed with a strong year-to-date return of +95.79%, driven by cement majors and manufacturing stocks. The NGX Premium Index, reflecting the performance of the exchange's largest and most liquid stocks, returned +70.32%, outperforming the ASI by nearly 19 percentage points. The NGX Lotus II Index, tracking Sharia-compliant equities, also performed well with a +85.15% year-to-date return.
In contrast, the banking and consumer goods sectors significantly underperformed. The NGX Banking Index was up +35.77% year-to-date, while the NGX Consumer Goods Index saw a +18.14% return. The NGX Insurance Index was the only major productive-sector index in negative territory, with a year-to-date return of -1.75%.
