The traditional Buffett Indicator, market capitalisation divided by GDP, suggests Nigeria is structurally ‘cheap.’ However, post-rebasing data and NGX composition dynamics indicate that this interpretation may be statistically misleading in frontier economies with high informality and ownership concentration.
For full year 2025, Nigeria’s nominal GDP stands at approximately $307.5 billion (N441.53 trillion), with non-oil GDP estimated at N423.87 trillion after stripping oil’s approximately 3.5-4 percent contribution and assuming approximately N1,436/$1 at year end.
NGX total market capitalisation is approximately N157 trillion as at August 31st 2026, with free-float adjusted capitalisation estimated at N41.10 trillion, as our computation works out to around 26 percent, consistent with sector ownership structures (financial services: 57 percent, industrials: 7 percent, conglomerates: 56 percent, consumer goods: 13 percent, etc.).
This produces a structurally adjusted valuation framework of approximately 0.10, implying an Investable Economy Ratio (IER) of roughly 10 percent, significantly below emerging market medians (30-55 percent) and developed markets (100 percent+).
At face value, this suggests deep undervaluation. However, I would caution against linear interpretation. Nigeria is not a cheap equity market rather it is a shallow proxy for a deep but only partially publicly investable economy. The structural explanation lies in three empirically observable distortions:
First, listing density remains low. A large share of GDP is generated by unlisted conglomerates, SMEs, and informal enterprises (50-70 percent of GDP), meaning GDP expansion does not translate proportionally into investable equity supply. In 2025, the Nigerian Exchange (NGX) recorded zero IPO.
In South Africa, at least 5 new firms IPO’ed on the local bourse, while India recorded 373 (103 mainboard and 270 SME). The NGX has just 147 listed firms.
The Johannesburg Stock Exchange has more than 430. India has 5,500 unique companies listed across its two massive stock exchanges. The Technology Board since its launch in 2022 has not recorded a single IPO.
Second, free-float constraints distort market depth. Data shows heavy concentration in a small number of stocks, with over 90 percent of market capitalisation driven by SWOOTs (Stocks Worth Over One Trillion).
The top ten companies with market capitalisation of over N5 trillion each, a subset of the SWOOT group, Airtel (N23.68trn), Dangote Cement (N17.45trn), MTNN (N16.94trn), BUA Foods (N13.69trn), BUA Cement (N10.46trn), Seplat (N7.39trn), First HoldCo (N6.45trn), Aradel (N6.15trn), HBM Nigeria (N5.40trn), and Zenith Bank (N5.23trn), alone are responsible for 72 percent of the total market capitalisation.
The top 20 and top 30 listed firms are responsible for 87 percent and 94 percent respectively. These three categories are also responsible for 69 percent, 86 percent, and 93 percent of the total free float value on the exchange. This concentration risk limits breadth and investable dispersion.
Third, earnings-to-valuation mismatch is narrowing but uneven. While banking sector profitability has expanded under higher interest rate regimes and FX reforms, liquidity constraints and foreign participation volatility are structural market limitations that still suppress valuation convergence.
Foreign portfolio participation, which stood at 19 percent of transaction value in August 2025 (vs. 8 percent in July), fell to 12.1 percent by H1 2026 and touched a 2026 low of 9.45 percent in May and 6 percent in July, even as monthly turnover of N1.5-2tn against a N157tn market cap underscores persistently thin secondary-market liquidity
The Dangote Petroleum Refinery IPO will end the NGX’s IPO drought. However, it will not resolve the concentration problem. In fact, it will deepen it. At $40-50 billion implied valuation, the refinery’s full equity value alone would equal 34-42 percent of the NGX’s entire current market capitalisation of roughly $118 billion.
Even accounting for the fact that only about 10 percent of the company is being floated, the newly floated N7 trillion-equivalent ($5 billion) would immediately constitute roughly 15 percent of the NGX’s total free float (N41.10 trillion plus the new float), making it, on day one, the single largest free-float-weighted constituent on the exchange.
The listing therefore validates the IER framework’s core argument rather than undermining it: Nigeria’s market is not becoming more representative of its economy through this IPO. Instead, it is becoming more concentrated in fewer, larger, closely-held names, precisely the ‘SWOOT-ification’ dynamic, only now with a new apex name at the top of it.
Empirically, this divergence between GDP growth and market capitalisation growth suggests that NGX re-rating is driven more by financial deepening than pure earnings expansion.
It is more capital chasing the same narrow set of listed names, rising participation, and structural re-rating of index-eligible stocks, rather than by new corporate value being created and floated.
This is set to intensify, not resolve, as participation deepens from a genuinely low base with further growth in PFA quoted-equity holdings and retail turnover expected, even as only 10 percent of Nigeria’s six million CSCS accounts stay active.
Both cohorts will funnel toward the same liquid SWOOTs under prudential mandates, deepening concentration rather than resolving it, absent new listings and enforced free-float minimums. In plain terms, the pie isn’t getting bigger; more money is bidding for the same small number of slices.
The central mispricing risk in aggregate as a proxy for the economy is, therefore, not overvaluation or undervaluation; it is under-representation of the investable economy itself. At the constituent level, that does not mean the listed names themselves are fairly priced; ours is a market of undervaluation with significant non fundamental discounting factors.
The implication for institutional investors is clear: the next re-rating cycle in Nigerian equities will not be won by earnings growth alone. It will be won or lost on whether this market becomes structurally investable. That responsibility does not sit with policymakers alone. It sits with us: the investment bankers who structure the deals, the stockbrokers who distribute them, the asset managers who price them, the regulators who set the rules that make or break the incentive to list, and the founders and boards of private conglomerates and family-owned businesses who have chosen to stay private.
Three years of a silent Technology Board, a primary equities market in deep freeze, and a top 10 that already commands 72 percent of all value on the Exchange are not abstract statistics; they are a sobering verdict on our collective execution.
Nigeria does not lack investable companies. Rather, it lacks the capital-markets infrastructure, free-float discipline, and distribution conviction to bring them public and keep them liquid once they are.
Every year we accept a zero-IPO Tech Board as normal, we forfeit another cohort of unicorns to Delaware, London, or private equity exit – and we hand the next generation of Nigerian savers a market that is a proxy for a handful of billionaires’ balance sheets rather than for the economy they actually live in.
The tools to change this, from recalibrated listing requirements and real enforcement of free-float minimums even on flagship deals, to deeper retail and institutional distribution and a pipeline that reaches beyond SWOOTs into mid-cap, tech, and services companies, are within our control today. The only question is whether we treat NGX’s transformation into a genuinely investable economy as this decade’s defining mandate, or as someone else’s problem to solve later.
