The selection of funds can be based on the following three aspects: 1. When choosing an industry, investors can choose funds with great development prospects, high profit-making effect or good industry stability; 2. Choose a fund manager, you can choose a fund that has been in business for a long time or managed by a star fund manager; 3. Timing: The timing of fund entry is very important, mainly considering the market situation (when the market situation is good) and the fund position (when the position is low).
