Capitalization is the market value of a company whose shares are traded on the stock exchange. It is calculated by multiplying the market price of a share by the total number of the company's shares. Capitalization indicates volatility, risk, and growth potential. This metric is often used for a quick assessment of a company’s investment profile.^[1]

Capitalization is an important indicator for investors and analysts, as it helps determine the size and significance of a company in the stock market. Companies with large capitalization are considered more stable and reliable, as they have more resources and financial power to grow and survive in the market.

This metric can be divided into several categories: small (from 300 million to 2 billion dollars), medium (from 2 to 10 billion dollars), and large (over 10 billion dollars). Companies with different levels of capitalization have their own characteristics and risks, so investors usually take this indicator into account when making investment decisions.

Capitalization can also change over time depending on the share price and the number of shares in circulation. Therefore, it is a dynamic indicator that requires constant monitoring and analysis to make well-informed investment decisions.
