Today, we take the smart regular investment algorithm of an Internet ** sales platform as an example to talk about the principle and effect of smart regular investment in detail.
1. The principle of smart regular investment
The platform's smart regular investment adopts the ** model and selects a reference index, such as the CSI 500 Index, the CSI 300 Index or the ChiNext Index, etc.; Then choose a moving flat** to represent the historical average, for example, use 250 days** to represent the average price of the last 250 trading days**.
According to the **price and moving level of the reference index**, the deduction rate is dynamically adjusted: when the **price is higher than **, it will invest less, and when it is lower than **, it will invest more (if the amplitude of the past 10 trading days is large, the deduction will also be reduced to avoid the impact of abnormal **fluctuations).
Actual Subscription Amount = Basic Subscription Amount * Current Deduction Rate (60% Current Deduction Rate 210%).
We summarize the actual deduction rate of this kind of smart fixed investment in different situations in the following two **, the whole is two principles: the **price of the reference index is higher than the selected **, invest less, and lower than **, invest more; When the index price is lower than **, the amplitude of the past 10 days exceeds 5%, and the amplitude is less than 5%, and more is invested.
Second, the effect of smart regular investment
Let's take a look at the effect of this smart investment strategy
The reference index is CSI 500 Index, and the 250-day moving average is selected.
We used 5 different intervals to calculate the fixed investment range: 2015 year-to-date (2021 10 14), 2016 year-to-date, 2017 year-to-date, 2018 year-to-date, 2019 year-to-date.
The regular investment** of each type of regular investment range is all the ordinary **type** and partial stock hybrid ** that have been established before the start date of the regular investment.
Let's compare the difference between the returns of Smart Bi-weekly Regular Investment and ordinary Bi-weekly Fixed Investment, as shown in the chart below.
The following conclusions can be drawn:
1. The effect of this smart regular investment method is indeed better than that of ordinary regular investment; Using this smart regular investment method, the vast majority of ** returns are better than ordinary regular investment;
2. This kind of smart regular investment method is smaller than the excess return of ordinary regular investment, and the advantages are not obvious. If you have been investing since the beginning of 2015, the average annual increase of smart investment is 053% gain; Since the beginning of 2019, smart regular investment has been 1. more than ordinary regular investment on average every year33% gain.
3. The longer the time of regular investment, the smaller the excess return of smart regular investment, because the effect of timing will be ironed out by time, and timing cannot always be accurate; If it is a short- and medium-term regular investment, you can consider using this smart regular investment method.
4. Because the difference in income is relatively small, it is recommended that you still focus on the selection of the best; is also a regular investment, and the difference between the returns of the good and the bad will be very large; If you can choose a good **, you can basically ignore the small excess return of smart regular investment.
