The return on fixed investment depends on several points:

Fixed investment index fund target. The annualized income of Shanghai and Shenzhen 300 broad-based index is about 1 1%, and some industries have higher income, such as large consumption, medicine, internet, etc., which can be about 15%~20%. Buy when it is relatively cheap, and make a fixed investment in an uncertain way. The more you buy, the cheaper it is. You can refer to PE, moving average and other indicators, which are complicated and need a certain amount of time to accumulate, including a certain understanding of the industry or macroeconomic research.

Take profit and sell. Look at the cycle and purpose of your investment. For example, do you sell the market that rose by about 30% in the first half of the year? If you don't sell it, you have to take a roller coaster. However, if the index is easy to double in 2007 and 15, if it stops at 30%, it will be missed, and it is best to sell it in batches. Make a profit strategy according to your own expectations. You can also refer to the valuation.

1, daily fixed investment

Investors who choose daily fixed investment usually sell the fund when the trend of the fund falls for the purpose of short message investment.

But for most investors, the fixed investment of the fund has always been aimed at medium and long-term investment. Daily fixed investment is not only cumbersome to operate, but also easily affected by the fund's ups and downs, which leads to heavy buying when the fund rises, and it cannot be fixed when it falls, losing the true meaning of fixed investment.

2. Weekly fixed investment

The frequency of weekly fixed investment is actually relatively large, but some investors think that every Thursday is a more suitable time for fixed investment, so they choose to vote every week.

In the stock market, Thursday is called Black Thursday. Because the trading system of "T+ 1" is adopted in stock trading, some investors will choose to cash out their stocks on Thursday. This is also one of the main reasons why investors think Thursday is suitable for the fund to open positions.

In fact, judging from the historical data of the fund's fixed investment, whether it is a daily fixed investment or a weekly fixed investment, the expected income gap of long-term fixed investment is very small and almost negligible. Considering the operating cost and risk tolerance of investors, it is suggested that weekly or monthly fixed investment is better than daily fixed investment with too high frequency.
