[Extended information] Securities accounts refer to the account books established by securities registration and clearing institutions for investors to accurately record the types, names, quantities, corresponding rights and changes of securities held by investors.

Introduction: When investors buy stocks in the securities circulation market, they need to entrust a securities company and "open an account" with the other party, that is, the investor and the securities company sign a "securities purchase and sale entrustment contract."

For investors to open accounts, securities companies should conduct necessary investigations in advance.

For example, Rule 405 of the New York Stock Exchange stipulates that its member brokerage firms should try their best to understand the basic information of each customer and grasp the content of the trading instructions received.

If it is difficult for a securities company to understand the customer's situation, it can require the customer to pay a deposit or ask the other party to find a bank guarantee.

Its purpose is to ensure the safety and reliability of customer credit and enable securities transactions to proceed smoothly.

Usually when going through the account opening procedures, you need to fill in the "Entrusted Securities Trading Contract."

The content includes the client’s name, gender, age, place of origin, occupation, address, service organization, position, phone number, ID number, and signature and seal.

At the same time, the securities company should check the customer's ID card, compile an account number, fill out the "account opening card" and hand it to the customer.

In addition, customers should provide necessary explanations for stock transactions.

When opening an account, the securities company also provides the customer with the required account type.

Account Type: Cash Account: Upon purchase of securities, the client opening this account is required to pay the purchase price of all shares before or after the liquidation date.

Likewise, upon sale of shares, the shares should be delivered to the assessor on or before the liquidation date.

The specific date of closing the position will usually be stated in the stock "transaction notice" sent to the customer.

In the United States, the fifth business day after the trading day is the settlement day.

Margin account: also known as ordinary account.

When customers purchase securities, securities companies will provide investors with partial financing in the form of advance payments and charge interest on the advance payments.

For example, the margin ratio for an account is stipulated to be 65%, which means that the merchant must immediately pay 65% ??of the security price when purchasing securities.

The remaining 35% of the price and interest will be paid.

Converted based on borrowing costs provided by marketable securities.

Joint account: An investor opens an account at a securities company that is a partnership between two or more people.

This kind of household registration is suitable for husband and wife or father-son relationship.

Account at any time: When opening the account, the customer gives the securities company priority written consent and agrees to the securities company conducting transactions without consulting the investor.

Moreover, the trading objects, prices, quantities, and timing of stocks are all chosen by the securities firms themselves.

Of course, securities companies must not harm the interests of customers.

In many countries, investors can only open an account with a securities company if they reach legal age.

In European and American countries, the contractual behavior of minors is not legally binding.

Therefore, minors can hold stocks in name, but only parents can trade in the name of guardians.
