Market Capitalization

Market capitalization describes the market size of a company. Market capitalization is an equity market segregation used broadly in the investment industry. A company's market capitalization is an important characteristic considered by investment companies and individual investors. Market capitalization is one characteristic of a company used in investment analysis. Market capitalization is usually used in conjunction with other stock characteristics, such as price to earnings and earnings growth estimates. It is also an indicator of a company's market depth.

Market capitalization is calculated by multiplying the number of shares outstanding by the share price of the company's stock. The number of shares outstanding is reported on a quarterly basis, but the price of the stock can change from minute to minute. Therefore, the market capitalization value is actively changing with the market price. For example, a company with 10 billion shares outstanding, trading at $10 per share, has a market capitalization of $100 billion. Likewise, a company with 100 billion shares outstanding, and trading at a price of $1, also has a market capitalization of $100 billion.

Publicly traded stock issuance is used as a capital raising mechanism for publicly traded companies. When a company chooses to offer its shares for trading on the open public market, it typically uses share issuance as its primary equity capital raising tool. Thus, equity share management is a primary function used by well-established companies for capital, and shares outstanding are a part of that management process.

Market Capitalization Categories

Typically, stocks are lumped into three main categories of capitalization: large-cap, mid-cap and small-cap. However, mega-cap and micro-cap stock segregation may also be used. Mega-cap refers to stocks with a market cap of greater than $200 billion. Micro-cap is less than $300 million, and nano-cap may also be used for less than $50 million.

A large-cap company has a market capitalization of over $10 billion. A mid-cap company has a market capitalization between $2 billion and $10 billion, and a small-cap company has less than $2 billion in market capitalization. Large-cap companies usually have broader market issuance experience with greater access to the capital markets. Usually, large-caps have the greatest trading liquidity.

Investing in Large-Cap Stocks

Investors like to diversify their portfolios by investing in companies in different industries with varying market caps, revenues, and earnings growth projections. Due to their size, large-cap stocks are generally believed to be safer. While they do not offer the same growth opportunities as emerging mid-cap and small-cap companies, large-cap companies are innovative market leaders. As a result, their stock price can gain significantly through specific market initiatives or around groundbreaking market solutions.

Typically, investing in large-cap companies is used as a core long-term investment strategy within a portfolio because of their stability and dividends. Financial advisers usually suggest diversifying an investment portfolio by including small-cap, mid-cap, and large-cap stocks. Allocations and investment decisions are typically based on risk tolerance and investment horizons.
