Market Cap, short for Market Capitalization, is the total market value of a company’s outstanding shares of stock. It is calculated by multiplying the current share price by the total number of outstanding shares.

Types of Market Cap
Large Cap
Typically, companies with a market capitalization of $10 billion or more are classified as large-cap companies. These companies are usually well-established and have a stable performance history.

Mid-cap companies have a market capitalization between $2 billion and $10 billion. These companies are often characterized by growth potential and a slightly higher risk compared to large caps.
Small Cap
Companies with a market cap ranging from $300 million to $2 billion are considered small-cap. They may offer high growth potential but come with increased volatility and risk.

Micro-cap companies have a market capitalization between $50 million and $300 million. They are smaller in size and often present significant risks and potential rewards.
Nano Cap
The smallest category, nano-cap companies, have a market capitalization below $50 million. These are often the riskiest investments due to their size and liquidity constraints.
