Today’s article is based on one of the most important concepts in the stock market, that is MARKET CAPITALIZATION, and we will learn What Market Capitalization is, how to calculate it, and the different types of market capitalization like micro cap, small cap, mid cap and large cap.
First, let us understand Market Capitalization.
What is Market Capitalization?
In simple words, Market Capitalization means the total market value of a company’s outstanding shares in the stock market.
Market Capitalization is also known as Market Cap.
How to calculate Market Capitalization?
Market Cap = Total number of outstanding shares × Market price per share
Market capitalization keeps changing because stock prices change every day based on market demand and supply.
Let us look at an example of Nvidia.
Nvidia has 24.30 billion shares outstanding, and the share price is $190.
Market Cap = Total outstanding shares of Nvidia × Market share price
= $24.30B × $190
=Approximately $4.62 Trillion
This means Nvidia’s market value is around $4.6 trillion, making it currently the largest company in the world by market value due to the AI infrastructure boom.
(Here, B means Billion and $ means US Dollars)
Types of Market Capitalization
Friends, when we think about investing, we analyze a company’s fundamentals, and company market valuation is a very important part of that analysis. Based on company market valuation, we can estimate the risk level and growth potential of a company.
In the US Stock Market, Market Capitalization is broadly classified into four types:
- Micro cap
- Small Cap
- Mid Cap
- Large Cap
In the US market, this classification is commonly used by investors and financial institutions.
1)Micro Cap
Micro Cap companies are small companies that have a market value below $250 million. Micro Cap companies have very high growth potential, but if they fail to grow or go bankrupt, investors lose their entire investment.
2) Small Cap
Small Cap companies are those that do not fall under Large Cap or Mid Cap categories. Generally, companies with a market capitalization between $250 million and $2 billion are considered Small Cap companies. If the performance of Small Cap companies is good, they can move into the Mid Cap category over time. Before investing in Small Cap stocks, investors should do proper fundamental analysis, because Small Cap companies are more risky, but they also offer higher growth potential.
3) Mid Cap
Companies with a market capitalization typically between $2 billion and $10 billion are called Mid Cap companies. Mid Cap companies are less risky than Small Cap companies and offer a balance between growth and stability. If their performance continues to improve, they can eventually become Large Cap companies.
Mid Cap Example
- AppFolio $8.8 Billion
- Texas Roadhouse $6.5 Billion
4) Large Cap
Companies with a market capitalization of more than $10 billion are called Large Cap companies. These companies are considered less risky because they are well-established, financially strong, and often market leaders in their industries. Even if these companies face temporary losses, they usually have the capacity to recover. Returns from Large Cap companies are generally lower but more stable, making them suitable for long-term and conservative investors.
Large Cap Example
- Nvidia. $4.53 Trillion
- Apple $4.02 Trillion
- Alphabet $3.77 Trillion
