Before buying any stock, you should think like a part-owner of a business — not just someone buying a ticker symbol.
The question is:
“Is this company financially healthy, profitable, well-managed, reasonably priced, and likely to grow?”
That is what stock fundamentals help you answer.
Here are the major fundamentals every investor should understand before buying a stock.
1. Revenue (Sales)
This is the money the company generates from its business activities.
Ask:
Is revenue growing consistently?
Or is sales growth stagnant or declining?
A company with rising revenue usually indicates:
expanding customers
stronger demand
growing market share
Example:
A bank growing revenue from ₦1 trillion to ₦2 trillion over years is expanding economically.
But revenue alone is not enough.
A company can generate huge sales and still lose money.
2. Profit (Net Income / PAT)
This is what remains after expenses, taxes, and costs.
This is one of the most important metrics.
Look for:
consistent profitability
rising profits over years
stable margins
For Nigerian stocks, you’ll often see:
PAT = Profit After Tax
A company making:
₦500 billion profit today
₦600 billion next year
₦750 billion later
is generally strengthening.
But ask:
“Are these profits sustainable?”
3. Earnings Per Share (EPS)
EPS tells you:
how much profit belongs to each shareholder unit.
Formula:

If profits rise but shares increase massively, shareholders may not benefit much.
Higher EPS growth is usually positive.
4. Dividend History
Many Nigerian investors love dividend-paying stocks.
Check:
Does the company pay dividends consistently?
Is dividend growing?
Or does it skip payments often?
Strong dividend companies often indicate:
stable cash flow
mature business operations
shareholder-friendly management
Examples historically known for dividends:
Zenith Bank
Guaranty Trust Holding Company
MTN Nigeria
5. Price-to-Earnings Ratio (P/E Ratio)
This helps determine whether a stock is expensive or cheap relative to earnings.
Formula:

Example:
Share price = ₦50
EPS = ₦10
P/E = 5
Interpretation:
low P/E may mean undervalued
or market fears future problems
High P/E may mean:
growth expectations
or overvaluation
Always compare P/E with:
industry peers
historical averages
6. Price-to-Book Ratio (P/B)
Very important for banks and financial companies.
Formula:

If:
P/B < 1
the stock may be trading below the value of its assets.
For banks, this can signal:
undervaluation
or hidden risks
7. Debt Level
Too much debt can destroy a company.
Check:
Is debt manageable?
Can profits comfortably cover loans?
Is debt increasing dangerously?
A company drowning in debt becomes vulnerable during:
inflation
recession
FX crisis
high interest rates
This is very important in Nigeria’s high-interest environment.
8. Cash Flow
Profit is accounting. Cash flow is reality.
Some companies report profits but lack actual cash.
Check:
Is operating cash flow positive?
Can the company fund operations without borrowing excessively?
Healthy cash flow supports:
dividends
expansion
debt repayment
9. Return on Equity (ROE)
ROE measures how efficiently management uses shareholders’ money.
Formula:

Higher ROE generally means:
stronger management efficiency
better capital allocation
Banks often compete heavily on ROE.
10. Competitive Advantage (“Moat”)
Numbers matter. Business quality matters too.
Ask:
Why will this company still dominate in 10 years?
What protects it from competitors?
Examples:
strong brand
distribution network
regulation barriers
loyal customers
scale advantage
For example:
Dangote Cement has scale advantage.
MTN Nigeria has network dominance.
11. Management Quality
A great business can be ruined by poor leadership.
Study:
management reputation
governance quality
transparency
insider scandals
capital allocation decisions
Warning signs:
excessive dilution
suspicious acquisitions
inconsistent reporting
regulatory sanctions
12. Industry & Economic Environment
Even strong companies struggle in weak sectors.
For example:
high interest rates can help banks
but hurt manufacturing firms with heavy loans
Consider:
inflation
exchange rate
government policy
regulation
commodity prices
13. Valuation vs Growth
A stock can be:
a great company
but a bad investment at the wrong price
The key question:
“Am I paying a reasonable price for future growth?”
Even excellent businesses can become poor investments if bought too expensively.
A Simple Beginner Framework
Before buying any stock, ask these 7 questions:
Question
What You Want
Is revenue growing?
Yes
Is profit growing?
Yes
Is debt manageable?
Yes
Is cash flow healthy?
Yes
Does it pay dividends?
Preferably
Is valuation reasonable?
Yes
Do I understand the business?
Absolutely
If most answers are “no,” be careful.
For Nigerian Investors Specifically
Pay close attention to:
FX exposure
inflation impact
regulatory risks
dividend consistency
debt costs
ability to survive naira volatility
Many Nigerian stocks look “cheap” but are struggling fundamentally.
Cheap alone is not enough.
Final Principle
A stock is not automatically good because:
price is falling
people are hyping it
influencers are talking about it
dividend yield looks huge
Strong investing comes from combining:
business quality
financial strength
reasonable valuation
patience
That is the foundation of fundamental investing.

Preference shares have not died, but they are far less popular than ordinary shares for retail investors today, especially in the Nigerian market.
Here is the practical reality:
What Preference Shares Are
Preference shares are a hybrid between:
ordinary shares (equity), and
bonds/debt instruments.
They usually:
pay fixed dividends,
have priority over ordinary shareholders during dividend payment,
may have limited or no voting rights,
are generally less volatile than ordinary shares.
In accounting, companies’ equity section is often:
Ordinary Share Capital
Preference Share Capital
Retained Earnings
So what you learned is correct.
Why You Rarely Hear About Them Today
1. Nigerian companies hardly issue them publicly now
On the Nigerian Exchange Group (NGX), most companies raise money through:
ordinary shares,
corporate bonds,
commercial papers,
rights issues.
Preference share offerings are relatively rare.
2. Retail investors prefer capital growth
Most people investing today want:
price appreciation,
capital gains,
aggressive wealth growth.
Ordinary shares give that opportunity better.
For example:
a bank stock can rise 100–300%,
while preference shares may only pay a fixed dividend yearly.
So younger investors especially focus on growth assets.
3. Preference shares behave more like income instruments
They are mainly attractive to:
pension funds,
insurance firms,
institutional investors,
conservative investors needing stable income.
They are not usually “high wealth multiplier” assets.
Do Preference Shares Build Wealth?
Yes — but differently.
They are better for:
preserving capital,
generating predictable income,
reducing portfolio volatility.
They are weaker for:
explosive long-term wealth creation.
Think of it like this:
Asset Type
Main Goal
Ordinary shares
Growth
Preference shares
Stable income
Bonds
Capital preservation + income
Why You Don’t See Them on Many Investment Apps
Most Nigerian retail investment apps focus on:
ordinary NGX-listed stocks,
ETFs,
mutual funds,
treasury bills.
Preference shares have:
lower trading activity,
limited public offerings,
poor liquidity.
So apps may not prioritize displaying them.
Do They Still Exist?
Yes.
Some banks and companies still use preference shares privately or during restructuring/capital raising.
Globally, preference shares are still active in:
banking,
real estate,
infrastructure financing,
venture capital structures.
In advanced markets like the US and UK, preferred stocks are still traded actively.
How Someone Can Participate
In Nigeria
Opportunities are limited but possible through:
stockbrokers,
private placements,
corporate actions,
institutional offerings.
You would usually need:
a licensed stockbroker,
access to primary market offers,
notifications from issuing companies.
Examples of brokers/platforms include:
Meristem Securities
CardinalStone Securities
Stanbic IBTC Stockbrokers
Important Distinction Many Investors Miss
A lot of what preference shares were traditionally used for has now been replaced by:
mutual funds,
bond funds,
REITs,
dividend stocks,
ETFs.
These instruments are:
easier to access,
more liquid,
easier to understand,
available directly on apps.
So preference shares became less visible in retail investing discussions.
For Wealth Building, What Matters More Today?
For most retail investors in Nigeria:
quality ordinary shares,
ETFs,
dividend stocks,
equity mutual funds,
REITs,
disciplined long-term investing,
usually contribute more to meaningful wealth accumulation than preference shares alone.
Preference shares are more of a portfolio stabilizer than a wealth accelerator.
