A fund has different participants, besides investors, there are managers and custodians. They perform different duties in the operation of the fund. Fund manager: generally refers to institutions. The fund manager is the initiator and fundraiser of the fund, who is responsible for the operation of the fund assets, and uses his own professional knowledge and management methods to continuously increase the value of the fund assets and control the risks of the fund. The conditions for becoming a fund manager are very harsh. Not only do you need enough professionals, but you also need more than 654.38 billion yuan of paid-in capital to set up a fund. Fund custodian: China's "Securities Law" stipulates that where a fund is established, a fund custodian institution must be established. The fund custodian exists to protect the rights and interests of fund investors, and its purpose is to supervise the fund operation and keep the fund. Its responsibilities include but are not limited to asset custody, transaction supervision, information disclosure, fund settlement and accounting. Fund custodians are generally held by powerful and reputable financial institutions, mainly commercial banks in China. In short, fund investment needs to gather the funds of many investors. In order to safeguard the interests of investors, many processes of fund operation must be separated. Generally speaking, the fund manager is responsible for the daily fund investment, and the custodian is responsible for supervising whether the fund manager has violated the rights and interests of customers and other illegal acts.
