Stock Investing Fundamentals
The core terms behind buying and holding individual stocks.
Blue-Chip Stock
A share in a large, established company with a strong market position and operating history.
Example: A profitable national bank with decades of operations may be considered a blue-chip company.
A blue-chip stock is a share of a large, established, financially solid company with a long record of profits and, usually, dividends. On NGX the label attaches to the dominant banks, the major cement and consumer names, and the largest telecoms, the companies that anchor the All-Share Index.
The investmentAn asset or commitment of money made with the expectation of future income, growth, or both. case is durability, not excitement. Blue chips survive recessions and devaluations that kill weaker firms, pay dividends through most conditions, and offer the deepest liquidity on the exchange, meaning you can actually enter and exit at quoted prices. The cost of that safety is ceiling: trillion-naira companies rarely multiply the way small ones can.
The label is descriptive, not protective, and the caveats are real. Blue chips fall in crashes, sometimes severely; dominant companies decay (global markets are littered with fallen blue chips); and in Nigeria, even excellent naira earnings can be devalued away in dollar terms. Blue chip means quality business, not guaranteed return.
For beginners, blue chips are the sensible first stocks precisely because their financial statements are legible, their dividends teach the mechanics, and their liquidity forgives mistakes.
Buy Rating
A research opinion that a securityA tradable financial claim or ownership interest, such as a share, bond, or fund unit. is expected to deliver an attractive return relative to the analyst's standard.
Example: The analyst assigns a buy rating because the estimated upside exceeds the required threshold.
Buy Rating is a research opinion that a security is expected to deliver an attractive return relative to the analyst's standard; separate company performance from share-price performance: the business creates earnings and cash flow, while the market decides the multiple paid for them.
The analyst assigns a buy rating because the estimated upside exceeds the required threshold.
The practical test for Buy Rating is whether it improves future cash flow per share after considering the price paid, financing used and new risks assumed; a rising share price can coexist with deteriorating business value, and the reverse can also occur.
Common Stock
A share that usually carries voting rights and a residual claim on a company's profits and assets.
Example: A common shareholder may vote at meetings and receive dividends when declared.
Common Stock is a share that usually carries voting rights and a residual claim on a company's profits and assets; the economic meaning of the transaction should be traced to per-share cash flows, voting or distributionIncome or realised gains paid by a fund to its unitholders. rights and the effect on the company's capital structureThe mix and ranking of a company's debt, preferred securities, and equity financing..
A common shareholder may vote at meetings and receive dividends when declared.
The practical test for Common Stock is whether it improves future cash flow per share after considering the price paid, financing used and new risks assumed; the market may price an expected event before the formal announcement.
Cyclical Stock
A share whose business results tend to rise and fall with the economic cycle.
Example: Car manufacturers and construction companies often perform better during economic expansions.
Cyclical Stock is a share whose business results tend to rise and fall with the economic cycle; the economic meaning of the transaction should be traced to per-share cash flows, voting or distribution rights and the effect on the company's capital structure.
Car manufacturers and construction companies often perform better during economic expansions.
For Cyclical Stock, inspect the company's filings, per-share effect, cash-flow consequence, dilution, control rights, eligibility dates and the board's stated rationale.

An investor may own 5% of the economic interest but less than 5% of the voting power.
The practical test for Economic Interest is whether it improves future cash flow per share after considering the price paid, financing used and new risks assumed; corporate actions can transfer value without creating it.

Example: An equity analyst builds earnings forecasts and publishes a valuation estimate.
Equity Research is the analysis of companies, industries, financial statements, valuation, and risks to support share-investment decisions; the transaction can change an investor's ownership percentage, claim on future earnings or route to liquidity even when the underlying business has not changed immediately.

Market Capitalisation
The market valueThe price at which an asset could trade in the market at a given time. of a company's outstanding shares, calculated as share price multiplied by shares outstanding.
Example: A company with one billion shares at ₦20 has a ₦20 billion market capitalisation.
Market capitalisation is a company's total price tag: share price multiplied by shares outstanding. A bank with 30 billion shares at ₦40 has a market cap of ₦1.2 trillion, and that figure, not the ₦40, is what the market says the whole business is worth.
The measure makes companies comparable. Share prices are arbitrary (they depend on how many pieces the company is cut into); market caps rank actual size. This is why index weights, the ASI's construction, and "largest companies on NGX" lists all run on market cap, and why a high-priced share can belong to a small company and a low-priced share to a giant.
Size classes carry investment meaning. Large caps dominate index movements and offer the deepest liquidity; small caps trade thinly, swing harder, and can be moved by modest orders, which is where both opportunity and manipulation live on NGX.
Market cap prices only the equity. It ignores the company's debt; enterprise valueThe value of a company's operations attributable to debt and equity investors, commonly market capitalisation plus net debt and other claims. adds that back. And it is opinion, not appraisal: a market cap can double or halve while the underlying business barely changes, which is the entire premise of value investingAn approach that seeks assets trading below an estimate of their underlying worth..

A share in a company with a very small market capitalisation.
Example: A micro-cap share may have limited analyst coverage and low trading liquidity.

A share in a company with a medium-sized market capitalisation relative to its market.
Example: A growing manufacturer may fall into the mid-cap segment.
Mid-Cap Stock is a share in a company with a medium-sized market capitalisation relative to its market; the economic meaning of the transaction should be traced to per-share cash flows, voting or distribution rights and the effect on the company's capital structure.
A growing manufacturer may fall into the mid-cap segment.
The practical test for Mid-Cap Stock is whether it improves future cash flow per share after considering the price paid, financing used and new risks assumed.
Penny Stock
A very low-priced, small-company share that often carries high volatilityThe degree and frequency of price or return fluctuations. and liquidity riskThe risk that an asset cannot be sold quickly at a reasonable price or a redemption cannot be met promptly..
Example: A thinly traded share priced below ₦1 may be described as a penny stock.
A penny stock is a very low-priced, small, thinly traded share, NGX's kobo-priced tail is full of them. The low priceThe lowest traded price during a stated period. is the lure: ₦50,000 buys thousands of shares, and a move from 30 kobo to 60 kobo doubles your money. The same arithmetic that attracts is what the risks feed on.
Understand why the price is low. Usually the company is small, struggling, or opaque; sometimes it barely operates. Thin trading means wide spreads and the real possibility that you cannot sell at anything near the quoted price. And illiquidity makes penny stocks the natural habitat of manipulation: a coordinated pump needs little money to double a kobo stock before dumping it on late buyers.
The beginner's error is treating price as valuation. A 40 kobo share is not "cheap" and a ₦400 share "expensive"; cheapness is price against earnings and assets, and many penny stocks are expensive at any price because the underlying business earns nothing.
If you speculate here anyway, do it honestly: money you can lose entirely, positions sized for illiquidity, limit orders always, and no averaging down on a falling story.
Preferred Stock
A class of share that usually has priority over ordinary shares for dividends and liquidationThe process of selling an entity's assets, paying creditors, and distributing any remainder to owners. proceeds.
Example: A preferred shareholder receives the stated dividend before common shareholders.

Read the formal announcement or offer document for Preferred Stock; confirm the dates, ratios, price, treatment of fractions, tax and action required from the shareholder.
Price Target

Example: A broker sets a 12-month price target of ₦80 for a share trading at ₦60.
