Fund manager. From the perspective of the industry, the fund manager's past performance reflects the strength of the industry. In detail, the strength of each manager should be compared from the scale and nature of the fund operated by the manager. Take China as an example. There are many Wang Yawei and Xu Xiang, one of the former public offering brothers, but not many foreign countries. Powerful fund managers control the life and death of many rich people and institutions. There is no comparison between fund managers and stockbrokers. To some extent, one is in the sky and the other is underground.
