Up a few points, down a few points, that is, up a few percentage points and down a few percentage points that day. For example, a rise of 5 points on the same day means that the fund rose by 5% on the basis of yesterday's net value, and the calculation method of income is: principal × rate of return. For example, when an investor buys a fund of 10000 yuan, when the fund rises by 5 points, the calculation method is: 10000 yuan ×5%=500 yuan (excluding the handling fee).

The above example does not include the handling fee. When investors buy funds, if they buy funds with front-end charges, the system will deduct the subscription fee at one time; Buy back-end funds, and charge subscription fees according to the holding time; If you buy a Class C fund, you don't need a subscription fee at the time of purchase, but you will accrue a sales fee every day after purchase.

Generally speaking, investors do not need to calculate the income of the fund after purchasing it. General fund companies will announce the fund net value of the day after 9 pm. After the net value is announced, investors can see the profit and loss of the day.
