Don't Buy the Stock Until You Understand the Business

A stock is not simply a number moving up and down on a trading screen.

Behind every share price is a real business—with customers, products, employees, assets, debts, competitors, management and, ultimately, the ability or inability to make money.

This is the starting point of fundamental ,analysis.

Fundamental analysis is the structured process of examining the underlying business and its financial and economic conditions to determine its quality, financial strength, growth prospects, risks and underlying value.

For a long-term investor, the central question is not:

"Will this share price go up tomorrow?"

It is:

"Is this a good business, and am I paying a reasonable price for a share in it?"

That distinction is important.

A company can have an excellent business but an excessively expensive share price. Conversely, a struggling company can experience a temporary rise in its share price without becoming a fundamentally better business.

Fundamental analysis helps investors look beyond the market noise and examine what really matters.

What Is Fundamental Analysis?

Fundamental analysis is a structured approach to evaluating a company by studying its business model, industry, financial performance, financial position, cash flows, management, competitive advantages, risks, and valuation.

The objective is to develop an informed view of the company's ability to generate sustainable earnings and cash flow and create value for shareholders.

This means that fundamental analysis goes considerably further than looking at whether a company's share price has risen or fallen.

For example, suppose Company A's share price has increased by 40% over the past year.

That sounds impressive.

But before concluding that the company is a good investment, a fundamental investor would ask:

• Has revenue increased?
• Has profit increased?
• Has earnings per share increased?
• Is the company generating cash?
• Is debt rising?
• Are profit margins improving or declining?
• Is the business gaining or losing market share?
• Does the company have a competitive advantage?
• Is management allocating capital effectively?
• Are the company's prospects improving?
• And most importantly, has the share price risen beyond what the company's fundamentals justify?

This is the difference between watching a stock and analysing a stock.

Why Does Fundamental Analysis Matter?

Many factors affect share prices in the short term - Investor sentiment, Market rumours, News, Speculation, Interest rates, Economic conditions, Foreign exchange movements, Political developments, Investor expectations.

Some of these factors may have little immediate connection with the underlying performance of the business.

Fundamental analysis provides a framework for separating temporary market movements from changes in the underlying business.

The chapters on which this series is based emphasise that fundamental analysis is particularly relevant to long-term investing because it focuses on earnings power, financial strength, competitive advantage and sustainable value creation rather than daily price movements.

That does not mean fundamental investors ignore the share price.

Quite the opposite.

Price is critical—but price must be considered alongside value.

The Five Questions Every Fundamental Investor Should Ask

Before buying shares in a company, it is useful to reduce the analysis to five fundamental questions.

1. What does the company do? Can you clearly explain how the company makes money?

2. Is the business financially healthy? Is revenue growing? Are profits sustainable? Is the company generating cash? Is debt manageable?

3. Does the company have a competitive advantage? What makes it difficult for competitors to take its customers or erode its profitability?

4. What could go wrong? What are the company's financial, operational, regulatory, economic and industry risks?

5. Am I paying a sensible price? Even an excellent business can become a poor investment if you pay too much for it.

These five questions provide the foundation for a much deeper analysis.

Therefore, to fundamentally analyze a company with a view to investing in its stock requires a step-by-step procedure

Step 1: Understand the Business

The first mistake many new investors make is starting with financial ratios before understanding the company.

Start with the business.

Ask:

What does the company sell?

Who buys its products or services?

How does it make money?

What are its major sources of revenue?

What are its major costs?

Who are its competitors?

What drives demand for its products?

What could cause customers to leave?

The answers provide the context needed to understand the numbers that come later.

For example, a 20% increase in revenue means very different things depending on the business.

For a fast-growing technology company, it might indicate increasing market penetration.

For a consumer company operating in an inflationary environment, it might partly reflect higher selling prices rather than higher volumes.

For an oil company, revenue may be strongly influenced by commodity prices and production volumes.

The number alone does not tell the whole story.

You need to understand what is driving the number.

Step 2: Understand the Industry

A company does not operate in isolation.

It operates within an industry—and the industry's characteristics can have a major influence on its performance.

Consider a Nigerian bank.

Its performance may be affected by: Interest rates, Loan growth, Non-performing loans, Capital requirements, Regulation, Economic growth, Foreign exchange conditions, etc.

A manufacturing company may be more exposed to: Energy costs, Imported inputs, Exchange-rate movements, Consumer demand, Infrastructure, Competition

An oil and gas company may be influenced by: Crude oil prices, Production volumes, Government policy, Security conditions, and Regulatory changes

This is why fundamental analysis requires both company-level analysis and industry-level analysis. 

Step 3: Look for a Competitive Advantage

A company may be profitable today without necessarily being a great long-term business.

The more important question is:

Can the company continue earning attractive returns in the future?

This brings us to the idea of a competitive advantage, sometimes called an economic moat.

A competitive advantage is something that makes it difficult for competitors to take customers or reduce the company's profitability.

Examples include: Strong brands, Large distribution networks, Low-cost production, Economies of scale, Network effects, Customer loyalty, Proprietary technology. Regulatory licences, High barriers to entry.

Suppose two companies operate in the same industry.

Company A has a strong brand, extensive distribution, and loyal customers.

Company B sells essentially the same product but competes mainly by cutting prices.

Even if both companies are profitable today, Company A may have the stronger long-term competitive position.

The objective is therefore not merely to find a profitable company.

It is to understand why the company is profitable and whether that profitability can endure.

Step 4: Read the Financial Statements

Once you understand the business, turn to the numbers.

A company's annual report provides three particularly important financial statements:

1. Income Statement
2. Balance Sheet
3. Cash Flow Statement

Together, they tell different parts of the company's financial story.

The Income Statement

The income statement helps you understand the company's performance over a period.

You will typically find: revenue, cost of sales, gross profit, operating expenses, operating profit, finance costs, profit before tax, profit after tax, and earnings per share (EPS).

The first question is usually:

Is the company growing?

But don't stop at revenue.

You also want to know whether profits are growing and whether margins are improving.

Revenue Growth

Revenue represents the income generated from selling goods or services.

Suppose a company reports:

Revenue has increased by 20%. That looks positive. But what caused the increase?

Perhaps:

• Sales volumes increased.
• Prices increased.
• The company acquired another business.
• The naira depreciated.
• A new product became successful.

These explanations have different implications for future growth. This is why revenue growth should always be investigated rather than simply celebrated.

Step 5: Examine Profitability

Revenue is important, but revenue does not belong to shareholders. Costs have to be deducted before the company generates profit.

One useful starting point is gross profit.

Gross Profit = Revenue − Cost of Sales

You can then examine gross margin:

Gross Margin = Gross Profit ÷ Revenue, expressed in percentages.

Suppose a company generates ₦100 billion in revenue and ₦30 billion in gross profit.

Its gross margin is 30%.

Now imagine that three years later its revenue has grown to ₦150 billion, but gross profit has increased only to ₦37.5 billion.

The gross margin has fallen to 25%.

Revenue has increased significantly, but the company is retaining less gross profit from every naira of sales.

That could indicate rising input costs, pricing pressure, or increased competition.

The opposite trend can also be revealing.

If revenue and gross margins are both rising, the company may be benefiting from stronger pricing power, improved efficiency, or economies of scale.

Step 6: Don't Stop at Profit—Follow the Cash

One of the most important lessons in fundamental analysis is this:

Profit is not the same thing as cash.

A company can report substantial accounting profits while experiencing weak cash generation.

That is why investors should examine the cash flow statement.

In particular, look at: Operating cash flow, Investing cash flow, Financing cash flow and Free cash flow.

A healthy business should generally generate cash from its core operations.

A good fundamental analyst will compare profit growth, operating cash flow growth, and free cash flow generation. When profits and cash flows move together, investors have greater confidence in the quality and sustainability of reported earnings.

A Simple Example

Suppose:

This is encouraging.

Revenue increased, profit increased and operating cash flow also increased.

Now consider:

The second company deserves much more investigation.

Why are accounting profits increasing while cash generated from operations is falling?

Possible explanations could include rising receivables, inventory accumulation, aggressive revenue recognition, or other operational problems.

Step 7: Examine the Balance Sheet

The balance sheet provides a snapshot of the company's financial position.

It tells you about: Assets, Liabilities, Shareholders' equity, Debt, Cash, Receivables, and Inventory.

One of the most important questions is:

How financially strong is this company?

A company can have attractive profits but still be financially vulnerable if it carries excessive debt.

Investors should therefore examine: Debt levels, Short-term obligations, Cash balances, Receivables, Inventory, Shareholders' equity, and Ability to service debt

Excessive leverage is an important warning sign, particularly where debt is growing faster than earnings, interest costs consume significant profits or cash flow is insufficient to service obligations.

Step 8: Use Financial Ratios to Make Sense of the Numbers

Financial ratios help investors interpret financial statements and compare companies.

Some of the most useful ratios for beginners include:

Earnings Per Share (EPS) -EPS tells you how much profit is attributable to each ordinary share.

Price-to-Earnings (P/E) - P/E compares the market price of a share with its earnings per share.

Return on Equity (ROE) - ROE helps assess how effectively a company generates profit from shareholders' equity.

Debt-to-Equity - This provides an indication of the company's leverage.

Dividend Yield - Dividend yield measures dividend income relative to the share price.

Profit Margin - Profit margin shows how much of the company's revenue becomes profit.

But remember: A ratio is not a conclusion.

A P/E of 8x is not automatically cheap.

A P/E of 25x is not automatically expensive.

You need context.

Compare the ratio with: The company's historical levels, Competitors, Industry characteristics, expected growth, Profitability, Financial risk

Ratios become much more useful when compared across companies and over time rather than used in isolation.

Step 9: Look for Red Flags

Fundamental analysis is not only about finding strengths. It is also about identifying things that could go wrong.

Some important warning signs include:

Persistent negative operating cash flow - Particularly when the company continues reporting accounting profits.

Receivables growing much faster than revenue - This can raise questions about collections and earnings quality.

Excessive leverage - High debt can reduce financial flexibility and increase vulnerability when economic conditions deteriorate.

Frequent restatements - Repeated changes to previously reported financial statements may indicate weaknesses in financial reporting or internal controls.

Qualified audit opinions - These require careful investigation because they may identify issues affecting the reliability of the financial statements.

Unexplained related-party transactions - Large or poorly explained transactions involving directors, major shareholders or affiliated companies can raise governance concerns.

Sudden accounting policy changes - Investors should understand why accounting policies changed and how those changes affect reported results.

One red flag does not necessarily mean a company is a bad investment. The important issue is whether several warning signs appear together and whether they point to a deeper structural problem.

Step 10: Assess Management

Numbers tell you what happened.

Management can help explain why it happened and what may happen next.

Investors should consider: Management's track record. Strategic decisions. Capital allocation. Communication with shareholders. Corporate governance. Board independence. Internal controls. Transparency

A company may have strong financial results today because of favourable market conditions.

The more important question is whether management has demonstrated the ability to allocate capital effectively and navigate difficult conditions.

Step 11: Consider the Nigerian Economic Environment

For Nigerian investors, fundamental analysis cannot stop at the company.

The broader economy matters.

Pay attention to:

Inflation - High inflation can increase operating costs and reduce consumers' purchasing power.

Interest rates - Interest rates affect borrowing costs, investment decisions, consumer spending and valuations.

Exchange rates - Naira depreciation can increase the cost of imported inputs and foreign-currency debt, while companies with significant foreign-currency revenues may experience different effects.

Regulation - Regulatory changes can materially affect companies in sectors such as banking, telecommunications, oil and gas, and financial services.

Fiscal policy - Government taxation, spending and borrowing can influence economic activity and corporate profitability.

This company-plus-economy approach is particularly important in Nigeria, where inflation, interest rates, exchange-rate movements and regulation can materially influence corporate performance.

Step 12: Finally, Ask What the Stock Is Worth

This is where valuation comes in.

After studying the business, industry, financial statements, management, and risks, you still have one critical question:

What price should I be willing to pay for this business?

This is the distinction between quality and value.

A company may be:

• Excellent but overpriced
• Average but fairly priced
• Weak but apparently cheap
• Excellent and attractively priced

The last category is what fundamental investors are generally looking for.

The chapters emphasise that even a high-quality business can produce disappointing investment returns if purchased at an excessive valuation.

A Practical Fundamental Analysis Checklist

Before buying a Nigerian stock, work through this checklist:

If you cannot answer these questions, you probably haven't analysed the company deeply enough.

Fundamental Analysis Is a Process, Not a Single Ratio

Perhaps the most important lesson for a new investor is that there is no single number that tells you whether a stock is a good investment.

A low P/E does not automatically make a stock cheap.

High revenue growth does not automatically make a company attractive.

A high dividend yield does not automatically mean a sustainable dividend.

High ROE does not automatically mean excellent management.

And a rising share price does not automatically mean improving fundamentals.

Fundamental analysis works by putting the pieces together.

Business quality + financial strength + earnings + cash flow + competitive advantage + management + risk + valuation = a more complete investment decision.

The Bottom Line

Fundamental analysis is ultimately about understanding what you are buying.

When you buy shares in a listed company, you are buying an ownership interest in a business. The long-term value of that investment depends largely on the business's ability to generate sustainable earnings and cash flow, maintain its competitive position, manage risks and allocate capital effectively.

For the Nigerian investor, the process should go even further by considering the economic environment in which the company operates.

So before buying your next stock, don't begin with:

“How much has the share price increased?”

Begin with:

“What does this company do, how does it make money, how financially strong is it, what could go wrong—and what am I paying for it?”

That is where fundamental analysis begins.

And that is the foundation of intelligent long-term stock investing.
