Contrary to the principle of long-term investment, the transaction cost of funds is very high. The reasons for not recommending daily trading funds are:

1. Contrary to the principle of long-term investment, the fund mainly invests in stocks, which is suitable for long-term holding, and the probability of earning and expected income from holding the fund for a long time is greater. Japanese trading funds violate the principle of long-term investment.

2. The fund's transaction cost is very high, and intraday trading is not cost-effective. Long-term holding of funds can be exempted from handling fees.
