24 Firms Dominate Over 70% of Nigeria’s Stock Market Value

A new report has revealed that just 24 companies account for more than 70 percent of the total value of Nigeria’s stock market, highlighting the level of concentration within the country’s capital market.

The firms, which include leading banks, telecom operators, and major industrial companies, dominate trading activities on the Nigerian Exchange (NGX). Analysts say this concentration raises questions about market diversity and the risks associated with overdependence on a few large players.

Minister of Solid Minerals Development, Dele Alake, who disclosed the figures during a recent briefing, noted that the dominance of a small number of firms reflects both the strength and limitations of Nigeria’s capital market. He explained that while these companies provide stability, the lack of broader participation limits opportunities for growth.

“The reality is that 24 firms control over 70 percent of the market. This shows the need to encourage more companies to list and expand investor options,” Alake said.

Market experts argue that the concentration could expose investors to systemic risks if any of the dominant firms experience financial distress. They emphasise the importance of diversifying listings to include more medium-sized and emerging businesses.

The Nigerian Exchange has in recent years introduced reforms aimed at attracting new listings, but uptake has remained slow. Many companies prefer to remain private due to regulatory requirements and concerns about transparency.

Investors have also expressed concern that the current structure limits competition and innovation. “When a few firms dominate, smaller companies struggle to attract attention. This reduces the vibrancy of the market,” one financial analyst explained.

Despite the concentration, the presence of large firms has helped maintain liquidity and investor confidence. Companies such as Dangote Cement, MTN Nigeria, and major banks continue to drive trading volumes and contribute significantly to market capitalisation.

The Securities and Exchange Commission (SEC) has pledged to intensify efforts to deepen the market by encouraging more listings and strengthening investor protection. Officials say reforms will focus on improving corporate governance and reducing barriers for companies seeking to go public.

For Nigeria’s economy, a more diverse stock market is seen as critical to mobilising capital for growth. Analysts believe that expanding participation will not only reduce risks but also provide opportunities for new sectors such as technology and renewable energy.

As the debate continues, stakeholders agree that addressing market concentration requires coordinated action between regulators, government, and the private sector. The goal, they say, is to build a capital market that reflects the diversity and potential of Nigeria’s economy.
