What is Market Capitalization?

Market capitalization, or 'market cap,' is the total dollar value of a company's outstanding shares of stock. It's calculated by multiplying the company's total number of shares by the current market price of one share.

Market Cap = Total Shares × Stock Price

The Three Main Categories:

1. Large-Cap (>$10 billion): These are typically large, well-established companies with a strong history of stable growth (e.g., Apple, Microsoft). They are often considered safer investments.
2. Mid-Cap ($2 billion - $10 billion): These are companies in their growth phase. They offer a balance between the stability of large-caps and the growth potential of small-caps.
3. Small-Cap (<$2 billion): These are smaller, often newer companies with high growth potential, but they also come with higher risk.

Why Does Market Cap Matter?

Market cap gives you a quick sense of a company's size, which is a key factor in its risk and growth potential. A diversified portfolio often includes a mix of large-cap, mid-cap, and small-cap stocks to balance stability and growth.
