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.
