Investment and financial management methods:

Investors need to open corresponding investment and wealth management accounts before investing and wealth management. In order to prevent investors from falling into the misunderstanding of investment and financial management, resulting in property and spiritual losses, investors should go to formal financial institutions that meet the requirements of national supervision when opening investment and financial management accounts such as savings, insurance, stocks, bonds, foreign exchange, futures and gold.

Due to the wide distribution of bank outlets, investment and wealth management accounts opened through bank channels can be handled at bank counters. For insurance companies, investment and wealth management products such as life insurance and property insurance can be purchased through investment and wealth management accounts opened by insurance companies.

For securities companies, stocks (including A shares, B shares, H shares, etc.) and other investment and financial management tools. ), bonds (including government bonds, corporate bonds, corporate bonds, etc. ) and futures (including financial futures such as stock index futures and foreign exchange futures, and commodity futures such as gold futures and agricultural products futures) can be used for investment and wealth management.

The opening of a securities account can be handled in the business department of a securities company, and it needs to be handled within the trading day. Some securities companies can make online appointments through the websites of various provinces, and the opening time of accounts by appointment is also flexible, which can support opening accounts on Saturday and Sunday.
