2. You can use one-time investment or fixed investment.
3. If you have your own independent judgment on the level of the stock market and just have a lot of spare money to invest, you can choose your own time, buy and sell when the index is low and sell when the index is high.
4. If you are optimistic about the economy and the stock market for a long time, but have no confidence in judging the short-term high and low points, but only plan to invest in fixed income regularly in the future, you can adopt the method of fixed investment. If you buy an equal amount of fund shares on a certain day every month, you will stick to it for a long time, no matter whether the stock market goes up or down.
Index funds can be met at the bank counter, and the commission is relatively cheap. If you buy index funds, you don't have to worry about how to choose stocks, which is more suitable for lazy people to invest. If you invest in index funds, you don't have to worry about the ups and downs of the market.
The return of fixed investment index funds will depend on the average cost of your purchase and the timing of your final redemption.
