According to the regulations, there is no income from the fund's purchase on the same day, and it will not be profitable until the next trading day. If you buy the fund before the trading day 15: 00, you will see the income coming in the next day. It should be noted that if you buy the fund after the trading day 15: 00, you won't get any income until the third working day.

The act of buying a fund is called fund subscription. Generally speaking, the subscription rate of purchasing funds varies from channel to channel, and the subscription fees of brokers and banks are rarely discounted. Fund companies' official channels and third-party Internet channels generally offer a discount of 1%, so it is more cost-effective to buy funds on platforms such as Alipay.

Matters needing attention in purchasing funds:

1. Arrange the proportion of fund types according to your risk tolerance and investment purpose, choose the fund that suits you best, and set the investment ceiling when purchasing partial stock funds.

2. Post-maintenance of your account. Although the funds are worry-free, you can't throw them away. Always pay attention to the new announcements on the fund website, so as to have a more comprehensive and timely understanding of the funds you hold.

3. Pay attention to buying funds and don't care too much about the net value of funds. In fact, the fund's income is only related to the net growth rate.

4. Don't "love the new and hate the old" and don't blindly pursue new funds. Although the new fund has inherent advantages such as preferential prices, the old fund has long-term operating experience and reasonable positions, which is more worthy of attention and investment.
