The stock market is the place where issued stocks are transferred, traded and circulated, including exchange market and OTC market. Because it is based on the distribution market, it is also called the secondary market. The structure and trading activities of the stock market are more complicated than the issuance market (primary market), and its role and influence are also greater.
Stock trading is the buying and selling of stocks. There are two main forms of stock trading, one is to buy and sell stocks through the stock exchange, which is called floor trading; The other is to buy and sell stocks without going through the stock exchange, which is called OTC. Most stocks are bought and sold on stock exchanges, while over-the-counter trading is only perfect in the United States, but not in other countries, or it is just starting. The main process of stock trading (floor trading) is as follows: (1) Opening an account. If customers want to buy or sell stocks, they should first open an account with a brokerage company. (2) Through instructions, after opening an account, customers can buy and sell stocks through their brokers. Every time a stock is bought or sold, the customer gives an order to the brokerage company, and the brokerage company quickly transmits the customer's order to its broker in the exchange, and the broker executes the order. (3) During the trading process, as soon as the brokers in the exchange receive the instructions, they will quickly go to the trading desk (trading hall) where the stocks are bought and sold to execute the instructions. (4) Delivery: After stock trading, the buyer pays cash to obtain the stock, and the seller hands over the stock to obtain the cash. Some delivery procedures are carried out after the transaction, and some are completed through clearing companies within a certain period of time, such as a few days to dozens of days. (5) After the transfer and delivery, the new shareholder shall go through the transfer formalities with the issuing company where he holds the shares, that is, register his name and the number of shares held in the company's register of shareholders. When this step is completed, the stock exchange is finally completed.
The first thing that new shareholders should do is to open a stock account (that is, a shareholder card) for themselves. A stock account is equivalent to a "bank account", and investors can only buy and sell securities by opening a stock account.
