the implications of changes in market share and market growth

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: $$ \text{Growth Rate} = \frac{\text{Current Period Sales} - \text{Previous Period Sales}}{\text{Previous Period Sales}} \times 100\% $$
