Glad to answer your question,

Your question is.

The net value of the fund is 0.9 to 0.8.

Down 10%?

no

0.9~0.8

It has far exceeded 10%.

Generally speaking, reducing the net value of 0.09 from 0.9 is 10%.

That is, when the net value is 0.8 1.

, down 10%.

We use 100 to explain the problem more simply and clearly.

100 decrease 10%, which is 90.

90 drop 10%, that is, 8 1.

The increase in the same proportion is far less than the decrease.

For example, from 100, 10% fell for two consecutive times.

That is 8 1.

Then, starting from 8 1, it continuously increased by two 10%.

It is impossible to rise to 100.
