Fund agency refers to the institutions that engage in fund sales business with the approval of China Securities Regulatory Commission, including banks, securities companies and fund sales companies. Different fund institutions can open a fund account of the same fund company and purchase and hold the fund products of the fund company. This is because the fund products of fund companies are sold and served through fund consignment agencies, and investors can choose appropriate fund consignment agencies to open accounts and trade according to their own needs. Investors can consider factors such as credibility, service quality and cost when choosing fund institutions. The advantage of opening a capital account in the same institution is that it can be managed and traded in the same institution, which is convenient for investors to allocate funds and control risks.
