2. Overvaluation. Generally, when a fund continues to rise for a period of time and the fund valuation is high, it is more likely to fall, because the fund valuation is based on a certain price to estimate the assets and liabilities of the fund. If the fund valuation is too high, then the risk is greater and the possibility of fund collapse is greater.
3. Encounter unexpected events with great impact. The investment of the fund depends on entering the market. If the financial market has a relatively large impact of emergencies, it will also directly affect the fund. For example, the financial market will lead to a sharp drop in the stock market, which will affect the fund.
