What is the principal of the fund 100 a day?
How much principal the fund needs to earn 100 a day depends on the principal and the increase. For example, if there is a principal of 10000 yuan and the fund increases by 1%, the money you can earn in one day is 10000 *1%=10000 yuan, but the principal of10000 yuan is a little more. If investors don't have that much principal, they need the principal of the fund.
Then if the fund's increase is relatively high, it will require less principal. For example, if there is a principal of 2000 yuan, the fund will increase by 5%, and the money you can earn in one day is 2000 * 5% = 100 yuan.
The income of the fund is closely related to the principal and the increase. Generally, the higher the increase, the higher the principal and the more income. It should be noted that the fund may lose money when the market is bad, so you need to be cautious when buying funds, and you can't buy them at will.
