Index funds are different from other active stock funds, and their volatility is relatively small. The index represents the average level of the corresponding market as a whole or an industry sector, and the index is sustainable.
In the process of fixed investment of index funds, if the index falls sharply and the funds are sufficient, you can buy more and more, but the process of falling is painful. No one can predict when the next round of market will start. Long-term positions occupy cash flow, and the investment experience of falling market is not good.
When the overall market goes up, if there is a sudden plunge, you can consider adding positions, which is more likely to make profits later. This way of adding positions is relatively common, but there are certain risks in this way, because there is no absolute law of market changes. It takes courage to add positions in a falling market and it is also a heavy test for investors' mentality.
Ideally, you can add positions, but in practice, not everyone can insist.
In the falling market, whether to add positions ultimately depends on investors' own judgment on the market outlook. If you are firmly optimistic about the market outlook, then at this time, jiacang will be more decisive and persistent, and it will usher in a profitable opportunity. If you don't know the market outlook, you can't judge, but follow the footsteps of others or blindly take the way of adding positions after falling. Even if you add a position, it is easy to doubt your own operation in the follow-up process and it is difficult to persist.
If it is already a fixed investment operation, then it is a better way to adhere to the discipline of fixed investment.
