1. Decline in fund net value: Although the number of fund shares remains unchanged, the fund net value may decline due to market fluctuations, investment strategies and other factors. When the net value of the fund falls, the total value of the fund assets held by investors will also decrease accordingly, which may lead you to think that the number of shares will decrease.
2. Dividend or split: The fund may carry out dividend or split operation, which will reduce the net value of the fund and increase the number of shares. If you hold the fund before dividend or split, the number of shares you hold in the fund may increase after the operation is completed, but the net value of the fund will decrease accordingly. This may make you feel that the number of shares has decreased.
3. Portfolio adjustment: The fund manager may adjust the fund's portfolio according to market conditions, sell some stocks or bonds and buy other assets. This adjustment may lead to a temporary reduction in the number of fund shares, thus affecting the net value of the fund.
4. Transaction costs: buying and selling foundations generates certain transaction costs. If you buy a fund and sell it soon, you may lose money on the investment because of the transaction cost.
In view of the greater losses you mentioned, I suggest you have a deep understanding of the investment strategy, asset allocation and investment ability of fund managers. At the same time, please pay attention to the systemic risk of the market and the individual's investment risk tolerance to ensure that your investment decision is in line with your risk preference and investment objectives.
When investing in a fund, please pay attention to the performance, investment risks and expenses of the fund, so as to better grasp the investment opportunities and achieve the investment objectives. If you need further investment advice, please consult a professional financial advisor.
