Generally speaking, it has something to do with the types of funds. If it is a money fund or a bond fund, it is difficult to double it, because the risk of money funds and bond funds is relatively small, and although the income is relatively stable, the money earned will not be particularly large, unless the principal is sufficient and held for a long time, the money earned may be more.
Generally, funds that can double are high-risk funds, such as stock funds, hybrid funds, index funds, QDII funds and so on. , but it takes a long time, and some may take more than one year to double, depending on the fund market and the increase.
In addition, it is worth noting that the fund has high returns and high risks. If the selected fund is not good or the market is not good, there will be losses, so you must carefully consider buying again.
To buy a high-risk fund, you can use the method of fixed investment, because there is no way to judge whether the fund belongs to a high position or a low position when buying. Fixed investment can average the fund share and reduce the risk.
Another trick is that you can adjust it when you buy it. For example, if you choose to increase your position when the fund falls, you will be more likely to buy at a low level, and you can make money after the fund rises.
