These shares are meant to be traded easily. People buy and sell them on a stock exchange. Some companies are listed on an exchange to help trading. Others are unlisted but still public. In the United States, these are usually types of corporations. In the United Kingdom, they are called public limited companies. Other places have different names, like SA in France or AG in Germany.

Public companies work by raising money through selling shares. This is called raising capital. Before this, only a few wealthy people or banks could help. Now, many different investors can provide funds. This helps a business grow much larger. When a company makes a profit, owners may get dividends. They can also gain money if the stock price goes up. This is called a capital gain.

History shows how companies change over time. Many businesses start as private companies. Later, they may have an initial public offering to become public. Facebook is a good example of this. It was a private company before its offering in 2012. Mark Zuckerberg owned 29.3% of its class A shares in 2013. This gave him enough power to control the business. He could also share the risk with other shareholders.

There are many rules for these businesses. In the United States, the Securities Exchange Act of 1934 is important. Companies with over 500 shareholders often must report under this act. They must also share information about their money. This helps the public and the government. Some laws, like the Sarbanes-Oxley Act, add even more rules.

Experts called auditors must check the company accounts. This helps make sure the math is correct. This can be a hard and costly job for a company.

Sometimes, a public company decides to go private. This is often called corporate privatization. A small group of investors might buy all the shares. They might do this through a leveraged buyout. Other times, one public company buys another. This can lead to a merger.

The size of a company is called its market capitalization. You find this by multiplying the number of shares by the share price. This helps people understand how much the company is worth in the market.
