So what is the stock? When you own a share in the company, you own a small share of the company. When the company receives a profit, you too can make a profit, and when the company is experiencing financial difficulties, your investments may also suffer. In addition, ordinary shares have the right to vote, which means that you not only own a part of the company, but also have the right to vote in some decisions made by the company. The more stocks you have, the stronger your voice in the company's affairs. Holders of preferred shares do not have the right to vote.

When you buy promotions, you are issued a paper certificate. Previously, investors physically kept these certificates, and some still keep them, but in today's electronic era, most brokerage firms keep certificates to their name on your name so that they can more effectively fulfill your trading orders.

Stock Exchange
Shares of publicly traded companies are bought and sold in the stock market (or stock exchange). In the above example, stock exchanges work as auction houses. These are trading platforms, on which buyers and sellers are going together for securities trading. NASDAQ and the New York Stock Exchange (NYSE) are stock exchanges.

Exchange simplifies buying and selling. You are using a stock broker, which is doing business with stock exchange. You can buy and sell shares, because your broker presents you on the stock exchange and facilitates your transactions.

Since most of the purchase and sale of shares occurs in one place (on the stock exchange), it allows you to find out the price of the action every second of the day. Thus, you can monitor stock price fluctuations depending on news, economic events, media messages, etc.

Historically, the trade was carried out personally in the physical stock exchange. Now some exchanges, such as NYSE, are still offering this, but also allow you to make transactions in electronic form. NASDAQ, on the other hand, is a completely electronic system in which transactions are accommodated through a branched computerized network.

Publicly traded companies
Corporations issue shares of their shares for the population to attract capital for growth and operating expenses.

In a simplified example, let's say, the company sells 1 million shares of $ 50 per piece. It very quickly attracts 50 million dollars of capital. The company then invests 50 million dollars back to the company (equipment, assets, employees, etc.). Then investors (or people who bought shares) hope that the company will receive a profit, expecting the stock price will increase accordingly.

When the corporation is public, its entire financial information is available to the public. The Securities and Exchange Commission (SEC) collects this information and provides it to investors. When investors are trying to decide whether to invest in a specific company, they can use a number of indicators (company's financial information, historical results, expectations for the future, etc.) to determine how much an action costs and whether it is something special. https://www.producthunt.com/@max_polyakov
