Some friends are confused when buying funds. For example, when they buy a fund, they lose 10%, and then when the fund goes up 10%, they find that the fund has not yet returned its capital. What's going on here? How much is the loss 10% fund? For example, interested friends come and have a look!

Generally speaking, when a fund loses money, it needs to increase more than the previous loss before it can recover its capital, rather than saying that it will recover as much as it loses. You can remember the formula to increase its capital to calculate.

The formula for increasing the return on capital is: increased return on capital interval =1(1-loss interval)-1, which means that when investors lose 10%, increased return on capital interval =1(1)

For example, suppose an investor bought a fund with a price of 1 0,000 yuan, but the fund fell by 10% within one month, then the money lost is: 1 0,000 *10% =10,000.

If you want to go back to the original 1 1,000 yuan, then you need to go up 10% to get back to your original cost. The above method is calculation. If investors do not add positions, if they add positions after losses, the increase will be smaller.

For example, when the net fund value is 1 yuan, investors buy 1000 shares and lose 10%, then the net fund value is equal to 0.9 yuan, that is, the loss is 1000 yuan, and they will increase1000 shares.

And the cost after adding positions = (1000×1+0.9×1000)/(1000+1000) = 0.95 yuan, and investors need funds to rise to 0.95 yuan, too.
