A fund manager whose company size is above the average needs certain strength to match the sponsor's current annual salary, and requires very high requirements in terms of contacts and specific practical skills. It is difficult for sponsors to pass the qualification examination, but it is easier to engage in sponsorship than fund managers, and besides top fund managers, sponsors' salaries are slightly higher than fund managers. If you are a sponsor, you must develop in a large brokerage firm to have a better future. Small brokerage business is limited, which has great restrictions on personal development.
