Nigeria’s equities market remains heavily tilted toward its biggest listed companies, as the top 10 firms on the Nigerian Exchange (NGX) recorded a combined market capitalization of N110.12 trillion in April 2026.
This is based on an analysis of market data tracking the performance of large-cap stocks.
The figure represents 70.73% of the NGX’s total equity market capitalization of N155.70 trillion, underscoring the growing dominance of blue-chip stocks.
The 10 largest companies on the Nigerian Exchange also account for 77.12% of the total SWOOT market capitalization of N142.79 trillion in the period under review, reflecting that a small group of mega-cap stocks now exerts outsized influence on valuation, liquidity, and investor sentiment.
What the data is saying
The top 10 listed companies continued to post strong gains across key performance indicators, reinforcing their position as the primary drivers of market growth.
Their combined valuation has risen significantly over the past year, reflecting sustained investor interest and favorable macroeconomic conditions.
- Between March 2026 and April 2026, market capitalization for the 10 largest companies increased by N23.15 trillion, rising from N86.96 trillion in March 2026 to N110.12 trillion in April 2026.
- Compared to April 2025, the top 10 added N68.28 trillion compared to N41.83 trillion recorded in April 2025, with several stocks more than doubling in value.
- On a year-to-date basis, the group gained N45.75 trillion from N64.37 trillion in December 2025
- The top 10 now account for 77.12% of the total SWOOT valuation of N142.79 trillion
This growth highlights the continued concentration of market value in a small group of dominant companies.
