Does a 20% increase in the fund mean a 20% gain?
If the fund bought by investors has no loss and no profit, the fund has increased by 20%, indicating that the fund has earned 20%. If you buy a fund for a period of time, the fund has suffered losses and gains before, then a 20% increase in the fund does not mean that it has earned 20%, because it depends.
Generally speaking, a 20% increase in the fund is already a good return. At this time, it is necessary to consider whether to redeem it. Generally speaking, funds need to buy at a low level and sell at a high level to make money, so it is very important to set a suitable take profit point.
The fund has gone up by 20%. Do you want to sell it?
It depends on the market situation of the fund. If the market situation of the fund is good and the fund is still rising, then you can consider holding it for a period of time, or selling part of it and leaving part to improvise. Even if the fund falls, the loss will not be as much as before, and at least part of it will be redeemed.
If the fund starts to show signs of decline and the market is not very good, then sell it at this time. Many people will earn 20% when they buy a fund. If they want to earn more, they will still increase their positions when the fund rises, but the subsequent fund has not been redeemed when it falls, so they will lose money.
