Understanding Market Capitalisation
Market capitalisation, commonly referred to as market capitalisation or simply market cap, is a method of measuring a company’s total value in the stock market. It is calculated by multiplying the company’s current share price by the number of outstanding shares.
Formula:
Market Cap = Share Price × Number of Shares Outstanding
This figure provides investors and analysts with a broad understanding of a company’s size, stability, and overall value. For example, if a UK company has 100 million shares selling at £5 each, its market capitalisation would be £500 million.
Why Market Capitalisation Matters
Market capitalisation plays a key role in shaping investment strategies. It is one of the first metrics that analysts examine before making financial decisions. Here’s why it’s so important:
- Helps determine company size
- Guides investment decisions and strategies
- Reflects a company’s market value and investor confidence
- Used to compare companies across industries
- Affects inclusion in stock indices like the FTSE 100

Market Capitalisation vs. Other Metrics
While market capitalisation is critical, it’s not the only factor to consider. Here’s how it compares to others:
- Market Cap vs. Revenue: Market capitalisation (market cap) is primarily related to a company’s stock value, whereas revenue refers to the company’s total sales.
- Market Cap vs. Enterprise Value: Enterprise value includes debt, providing a more comprehensive picture.
- Market Cap vs. Share Price: A high share price does not necessarily indicate a high market capitalisation.
Always use market capitalisation alongside other financial metrics for better analysis.
