With the improvement of investment awareness and the enrichment of financial products, more and more people begin to pay attention to fund investment. However, as a way of collective investment, whether the fund is held for a long time or sold at a high price and sucked at a low price has always been a topic of concern to investors. This paper will analyze this problem from many angles to help investors understand fund investment more comprehensively.

First, let's look at the advantages of holding funds for a long time. Holding funds for a long time allows investors to enjoy long-term investment returns. This is because fund managers can find companies with long-term investment value through asset allocation and valuation judgment, and continue to track their performance. Long-term holding can also reduce the transaction costs and taxes of investors and reduce the risks brought by market fluctuations. In addition, long-term holding can also bring dividend income and compound interest effect to investors.

However, long-term holding also has some disadvantages. First of all, changes in the market and economic environment will affect the performance of the fund. If there is systemic risk in the market, the income of holding funds for a long time may be hit hard. Secondly, the fund is a collective investment mode, which depends on the asset allocation and investment decision of the fund manager. If the fund manager's investment philosophy and strategy change, it may cause losses to investors.

Next, let's take a look at the advantages of high throwing and low sucking. Selling at a high price and sucking at a low price can enable investors to gain greater profit opportunities in market fluctuations. When the market share price falls, investors can buy fund shares at a low price, and then throw them out when the market picks up, so as to obtain the difference income. In addition, the investment mode of high selling and low sucking can also make investors respond quickly to the market and avoid losses.

However, high throwing and low sucking also have some shortcomings. First of all, it requires investors to master the market situation and investment skills, otherwise it may cause losses. Secondly, high throwing and low sucking will also increase transaction costs and taxes, and reduce the return on investment.

To sum up, whether the fund is good for long-term holding or high-throwing and low-sucking needs to be selected according to the individual's investment philosophy and risk tolerance. If investors are long-term investors and are willing to enjoy long-term investment returns, it may be more appropriate to hold funds for a long time. If investors respond quickly to the market and master advanced investment skills, then the way of high throwing and low sucking may be more appropriate.
