Snowball.com believes that the rise and fall of funds are related to market conditions, the ability of fund managers, the types of funds and other factors. Generally speaking, if the market as a whole is improving, fund managers have strong investment ability, and the industry or target in which the fund invests has good development prospects, then the fund may rebound or rise after experiencing a sharp drop. However, if the overall market is depressed, the fund manager fails to adjust his position or choose the wrong investment direction in time, and the industry or target invested by the fund encounters difficulties or risks, then the fund may continue to fall after experiencing a sharp decline, and may even lose all its principal. Therefore, for fund investors, don't blindly chase up and down. They should choose appropriate fund products according to their own risk preferences, investment objectives, investment duration and other factors, and pay regular attention to the changes in fund net worth, performance, positions and other information, and adjust their investment strategies in time. If you buy a fund with good quality and worth holding for a long time, you can choose to continue holding it, or increase your position appropriately in the case of a big drop in order to look forward to future earnings; If the quality of the fund you buy is poor and does not meet your expectations, you can choose to stop loss or change positions in time to reduce losses when you encounter a big drop.
