基金定投是指在固定的时间、金额和渠道进行投资，以达到分散风险、降低成本的目的。然而，有些基金并不能进行定投，这主要是因为以下原因：
- 基金的风险较高。一些基金的波动性较大，定投可能会加大投资者的风险。例如，一些指数基金和股票基金等，其价格会受到市场波动的影响，定投可能会让投资者在市场下跌时增加投资份额，从而加大投资风险。
- 基金的流动性不佳。有些基金的流动性较差，投资者难以在需要资金时以合适的价格卖出。如果投资者在定投过程中需要资金，可能会因为无法及时卖出基金而面临损失。
- 基金的费用较高。一些基金的费用较高，包括管理费、托管费、销售服务费等。如果投资者定投的金额和频率较高，这些费用会累积起来，对投资者的收益产生负面影响。
因此，投资者在选择基金进行定投时，需要了解基金的投资策略、持仓情况、历史业绩和费用情况等信息，以便做出更加明智的投资决策。

Fund investing at a fixed interval and fixed amount is called fund investing. It is designed to diversify risks and reduce costs. However, some funds cannot be invested through fixed-term investing, mainly due to the following reasons:
- The risk of the fund is high. Some funds have high volatility, and fixed-term investing may increase investors' risks. For example, some index funds and equity funds are subject to market fluctuations, and fixed-term investing may cause investors to increase their investment exposure during market downturns, thus increasing investment risks.
- The fund has poor liquidity. Some funds have poor liquidity, making it difficult for investors to sell at a suitable price when they need funds. If investors need funds during the fixed-term investing process, they may face losses due to the inability to sell the fund promptly.
- The fund has high fees. Some funds have high fees, including management fees, custody fees, sales service fees, etc. If investors invest at a high frequency and amount, these fees will accumulate and negatively affect investors' returns.
Therefore, when selecting funds for fixed-term investing, investors need to understand the investment strategy, position, historical performance, and fees of the fund in order to make more informed investment decisions.
