How to Use Valuation Ratios to Find Good Stocks on the NGX

Most Nigerian investors buy stocks based on price movement, social media recommendations, or broker tips. Very few buy based on valuation — the systematic comparison of what a stock costs against what the underlying business is actually worth. This gap between price-driven and valuation-driven investing is precisely where the most consistent long-term returns on the Nigerian Exchange are found — and where patient, analytical investors build wealth that momentum chasers never sustain.

Valuation ratios are the tools that make this possible. They convert raw financial data into comparable metrics that reveal whether a Nigerian stock is attractively priced, fairly valued, or dangerously expensive relative to its own history, its sector peers, and the broader market.

Why Valuation Ratios Matter on the NGX Specifically

The Nigerian Exchange has characteristics that make valuation discipline particularly rewarding. Information asymmetry between institutional and retail investors is significant — meaning genuinely undervalued stocks exist and persist longer than they would in more efficient markets. Retail investor behaviour is frequently momentum-driven — meaning overvaluation also persists longer than fundamentals justify before correcting sharply. The investor who understands valuation ratios operates with an analytical advantage over the majority of market participants.

Ratio 1 — Price-to-Earnings Ratio

The PE ratio — current share price divided by earnings per share — is the most widely used valuation measure globally and on the NGX. It tells you how many naira investors are paying for each naira of company profit.

A Nigerian stock trading at a PE of 5x is priced at five times its annual earnings. One trading at 25x is priced at twenty-five times earnings. Neither number is inherently attractive or expensive without context — which is why PE ratios must always be compared against three benchmarks simultaneously.

Compare against the company's own historical PE range. A stock trading at 6x earnings that has historically traded between 8x and 14x earnings is trading at a discount to its own valuation history — a potential opportunity worth investigating. Compare against sector peers. A bank trading at 5x PE when the banking sector average is 8x is either cheap or has a specific fundamental weakness that justifies the discount — and your job is determining which. Compare against the NGX market average. Stocks trading significantly below market PE without fundamental justification frequently represent value opportunities that patient investors can exploit.

Ratio 2 — Price-to-Book Ratio

The PB ratio compares a company's market value to its book value — the net asset value of the business if all assets were liquidated and all liabilities paid. A PB ratio below 1 means the market is pricing the company below the value of its own net assets — a situation that can signal genuine undervaluation in a fundamentally sound business.

For Nigerian banking stocks — where assets and liabilities are well-defined and regularly marked to current values — the PB ratio is particularly meaningful. Several Nigerian banks have historically traded below book value during periods of market pessimism, creating buying opportunities for investors who understood that the discount reflected sentiment rather than fundamental impairment.

Apply the same comparative framework as PE ratios. A PB ratio significantly below the company's own five-year average and below sector peers — without a corresponding deterioration in asset quality — warrants serious investment consideration.

Ratio 3 — Dividend Yield

Dividend yield — annual dividends per share divided by current share price — is both a valuation metric and an income measure. When a company's dividend yield rises significantly above its historical average, it typically means the share price has fallen rather than the dividend increased — a potential value signal for income-oriented investors.

A Nigerian blue-chip stock that historically yielded 6% annually now yielding 14% because its price has declined — while its dividend payment capacity remains intact — is telling a specific story. The market has discounted the price. The business has maintained its cash generation. The gap between current yield and historical yield represents a potential return opportunity for investors who correctly assess that the dividend is sustainable.

Always verify dividend sustainability before acting on a yield signal. Calculate the payout ratio — dividends per share divided by earnings per share. A payout ratio below 60% indicates the dividend is well covered by earnings and unlikely to be cut. A payout ratio above 90% indicates the dividend consumes nearly all earnings — making it vulnerable to even modest earnings decline.

Ratio 4 — Price-to-Sales Ratio

For Nigerian companies where earnings are temporarily compressed by one-time costs, restructuring charges, or cyclical industry downturns, the price-to-sales ratio provides a valuation perspective that PE ratios distort during difficult earnings periods.

The PSR compares market capitalisation to annual revenue. It is particularly useful for evaluating Nigerian consumer goods and industrial companies during periods when earnings are temporarily depressed by input cost inflation — allowing investors to assess whether the underlying revenue base justifies a valuation recovery once earnings normalise.

A Nigerian consumer goods company trading at 0.3x revenue during a period of naira-driven input cost pressure that has temporarily crushed margins may be significantly undervalued if historical margins — which the business has demonstrated the capacity to achieve — would produce earnings that justify a much higher valuation at normalised profitability.

Ratio 5 — Enterprise Value to EBITDA

EV to EBITDA — enterprise value divided by earnings before interest, taxes, depreciation, and amortisation — provides a valuation measure that accounts for a company's total capital structure rather than just equity market value. It is particularly valuable for comparing Nigerian companies with different debt levels, since PE ratios can make heavily indebted companies appear cheap when their true total cost is substantially higher than the equity market cap alone reflects.

Calculate enterprise value as market capitalisation plus total debt minus cash. Divide by EBITDA. Compare against sector peers with similar capital structures. A low EV to EBITDA relative to peers in the same industry — with similar growth prospects and capital requirements — identifies companies where the total business value is priced below what comparable businesses command.

Building a Valuation Screening Process for the NGX

Effective valuation-based stock selection on the NGX requires applying these ratios systematically rather than in isolation. No single ratio provides a complete picture — the analytical value comes from their convergence.

Begin by screening the NGX universe for companies trading below their five-year historical PE averages. Within that list, identify those whose PB ratios are also at or below historical lows. Cross-reference with dividend yield screens to identify companies where yield has risen significantly above historical averages. Calculate EV to EBITDA for remaining candidates to confirm that total capital structure valuation is consistent with the equity valuation signals.

The companies that appear attractively valued across multiple ratios simultaneously — not just one — are the strongest valuation-based investment candidates. Single-ratio cheapness can reflect genuine opportunity or genuine impairment. Multi-ratio cheapness in a fundamentally sound business almost always represents opportunity.

The Most Common Valuation Mistakes Nigerian Investors Make

Applying ratios without comparing them to benchmarks is the most widespread analytical error. A PE ratio of 8x is meaningless without knowing whether the historical range for that company is 6x to 10x — making 8x fair value — or 15x to 25x — making 8x dramatically cheap.

Ignoring the reasons for low valuations consistently produces value trap investments. The stock that screens as cheap across every ratio may be cheap because the market correctly anticipates fundamental deterioration that historical metrics do not yet reflect. Always investigate why a stock is cheap before buying it — and distinguish between temporary and permanent reasons for the discount.

Using ratios in isolation from qualitative analysis misses critical investment context. Valuation ratios tell you what a stock costs relative to financial metrics. They do not tell you whether the business quality, management integrity, and competitive position justify paying even that discounted price. Combine quantitative ratio analysis with honest qualitative assessment of business durability for the most reliable investment outcomes.

The Bottom Line

Valuation ratios are the language through which the Nigerian stock market communicates opportunity to investors willing to listen. PE ratios, PB ratios, dividend yields, PSRs, and EV to EBITDA collectively reveal whether any given NGX stock is priced attractively, fairly, or dangerously — relative to its own history, its sector peers, and the broader market.

Nigerian investors who build the habit of consulting these ratios before every purchase — and who resist the temptation to buy stocks that all ratios indicate are expensive regardless of how compelling the momentum appears — will build portfolios with consistently better risk-adjusted returns than the majority of market participants who buy based on price movement alone.

The best NGX stocks are rarely the ones everyone is talking about. They are frequently the ones trading below historical valuation averages while most investors are focused elsewhere — and valuation ratios are how you find them before the crowd does. Price is what you pay. Valuation is what you know about whether that price is worth paying.
