Historical Context
Market capitalization (commonly referred to as market cap) has been a fundamental measure of corporate value and financial stability since the inception of stock markets. Historically, it has served as a critical benchmark for comparing companies and assessing their size within an industry or market.
Types and Categories
Market capitalization is broadly classified into the following categories based on the total value:
- Large-Cap (Big-Cap): Companies with a market cap over $10 billion. These companies are typically well-established and financially stable.
- Mid-Cap: Companies with a market cap between $2 billion and $10 billion. These companies show potential for growth and can be more volatile than large-cap stocks.
- Small-Cap: Companies with a market cap between $300 million and $2 billion. They are often younger and have more growth potential but come with higher risk.
- Micro-Cap: Companies with a market cap below $300 million. These are highly speculative investments with significant risks.
- Nano-Cap: Companies with a market cap below $50 million. They represent the smallest stocks available and carry the highest risk.
