What Is Capitalization
Capitalization is a fundamental concept in the equity market, and it's essential to understand what it means. Market capitalization, or market cap, is the value of a publicly listed company.
It's calculated by multiplying the share price with the amount of outstanding shares. This figure determines a company's size, which is a basic determinant of characteristics like riskiness or volatility.
A company's market cap is used to compare its value to other companies and asset classes. For example, a company with 20 million shares outstanding that sell at $100 per share would have a market cap of $2 billion.
The investment community relies on market cap to determine a company's size and make informed investment decisions. Market cap is also used to compare the value of the equity market relative to other markets.
