The research department is the supporting department of fund investment, mainly engaged in macroeconomic analysis, industry development analysis and investment value analysis of listed companies, and provides research reports and investment suggestions to fund investment decision-making departments. In addition, the research department also has fund managers to manage funds. Compared with the seller's research, the buyer's investment research serves the investment manager, in order to gain the approval of the investment manager and promote the growth of the fund's net value and the fund's ranking in the market. The research of the buyer's researcher needs to provide clear investment advice to the investment manager and be responsible for the investment advice. For this reason, most reports have a fixed structure, including industry status, company status, business development and profit analysis, and finally investment suggestions. Buyer researchers pay more attention to the independence of their own research, integrate the logic and viewpoints of brokerage research, conduct more in-depth independent research with their own judgment, and draw clear conclusions, which requires high professional quality.
