3.1 The Nature of Marketing – Markets
What is Market Share? 📊
Market share is the percentage of total sales in a market that a company controls.
If a company sells 20 % of all phones in a country, its market share is 20 %.
It’s like a football team scoring 20 % of the goals in a season.
What is Market Growth? 📈
Market growth is the rate at which the total size of a market changes over time, usually expressed as a percentage.
For example, if the total number of smartphones sold in a year rises from 100 million to 110 million, the market growth rate is 10 %.
Implications of Changing Market Share
- Competitive Advantage: A higher share often means stronger brand recognition and pricing power.
- Economies of Scale: More sales can lower per‑unit costs.
- Market Influence: Companies with large shares can set trends and influence suppliers.
- Risk of Over‑expansion: Rapid growth may stretch resources and dilute quality.
Implications of Market Growth
- Opportunity: Growing markets create new customers and revenue streams.
- Investment Needs: Expansion often requires capital for production, marketing, and distribution.
- Competitive Pressure: A growing market attracts new entrants, increasing rivalry.
- Innovation Demand: Customers expect new features, pushing firms to innovate.
Example: The Smartphone Market ⚽️
Imagine the smartphone market as a football league:
- Each team (company) tries to win more matches (sales).
- The league table shows market share (points).
- When the league expands (market growth), new teams join and the competition intensifies.
Key Formulae
Market Share:
\$ \text{Market Share} = \frac{\text{Company Sales}}{\text{Total Market Sales}} \times 100\% \$
Market Growth Rate:
\$ \text{Growth Rate} = \frac{\text{Current Period Sales} - \text{Previous Period Sales}}{\text{Previous Period Sales}} \times 100\% \$

Exam Tip 💡
When answering questions about market share and growth, always:
- Define each term clearly.
- Use the formulae to calculate values where data is given.
- Discuss the strategic implications for a firm (e.g., pricing, product development, marketing spend).
- Support your points with real‑world examples or analogies to show understanding.
