Before jumping into the stock market, it's crucial to have a basic understanding of how it works and the important concepts involved. Here is a comprehensive guide to help you get started: What is a stock exchange? A stock exchange is a market where securities are traded. Securities are financial instruments, such as shares or bonds, that represent ownership in a company or represent a loan. The stock exchange acts as a middleman between buyers and sellers of securities, and transactions are conducted through members of the stock exchange, typically banks and investment firms. The exchange is regulated by the Securities Commission, a government agency. To start trading the US stocks you must first open an account with a regulated broker, there are many review websites that recommend regulated brokers. Like aforextrust. Investing in the stock market gives you the opportunity to make a profit or suffer a loss by investing in different companies' securities. How does trading occur on the stock exchange? Securities are traded in two main markets on the stock exchange: Primary market - this is where you can buy shares directly from the issuing company on a specific date, and the price is determined by a bidding process in which you participate. Secondary market - this is the main platform for securities trading, where you can buy and sell securities with other investors. Trading is conducted through a computerized system, and prices are determined based on supply and demand. Trading happens between a large pool of buyers and sellers, and the identity of the counterparty is not known to the trader. How is the value (price) of securities determined? Trading on the stock exchange occurs during a financial business day and is done using the relay method. Prices for each security can change multiple times during the trading day based on concluded deals. The closing price of a security at the end of the day serves as the starting price for the next business day. Trading hours for each type of security are predetermined and can be found on the stock exchange's website or on atadawul website. It's important to pay attention to the trading hours and restrictions for each security type. How do we invest in the stock market? Investing in the stock market is done through exchange members, such as banks or investment firms, which execute your orders. You can track the value of your securities through the investment management entity you choose. As a beginner, it's wise to consult with an investment advisor to determine the right amount and type of investment, including considering a level of risk that is appropriate for you. Keep in mind that investing in the stock market carries risks and takes time.
