Detailed Description
The following description of the embodiments of the present application is provided by way of specific examples, and other advantages and effects of the present application will be readily apparent to those skilled in the art from the disclosure herein. The present application is capable of other and different embodiments and its several details are capable of modifications and/or changes in various respects, all without departing from the spirit of the present application. It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict.
It should be noted that the drawings provided in the following embodiments are only for illustrating the basic idea of the present invention, and the components related to the present invention are only shown in the drawings rather than drawn according to the number, shape and size of the components in actual implementation, and the type, quantity and proportion of the components in actual implementation may be changed freely, and the layout of the components may be more complicated.
The embodiment aims to provide an intelligent stock recommendation system and method based on backtesting data and an electronic terminal, which are used for recommending more objective and high-accuracy stocks for users.
The principles and implementations of the system and method for intelligently recommending stocks based on measured data and the electronic terminal according to the present embodiment will be described in detail below, so that those skilled in the art can understand the system and method for intelligently recommending stocks based on measured data and the electronic terminal without creative work.
As shown in fig. 1, this embodiment provides an intelligent stock recommendation system based on measured data, which includes: the system comprises a screening model, a sequencing model, a retesting model and a recommending model.
The stock selection strategy in this embodiment is realized through a screening model and a ranking model, and the ranking model determines the stocks meeting the conditions through the screening model.
In this embodiment, as shown in fig. 2, the screening model screens the current stock data according to a configurable screening policy, and outputs the first stock data meeting the screening condition.
Wherein the screening conditions refer to market circulation value, time interval, market value and the like; the screening strategy comprises a configuration strategy for one or more combinations of the market value, the time interval and the market value.
In this embodiment, as shown in fig. 3, the sorting model sorts the first stock data meeting the screening condition according to a configurable sorting policy, and outputs the second sequentially arranged stock data meeting the sorting condition.
Wherein the sorting condition refers to deduction of non-net asset profitability, order, range, weight and the like, and the sorting strategy comprises configuration strategy of one or more combinations of deduction of non-net asset profitability, order, range and weight.
As can be seen from the above, in the present embodiment, the formulation of the stock selection strategy is mainly divided into two parts, the screening condition and the sorting condition.
The screening conditions are just like a sieve, some filtering conditions are specified in a stock set, the qualified filtering conditions are reserved as results, and the unqualified filtering conditions are eliminated. In addition to the filtering condition, the recommendation algorithm needs to use a sorting condition for determining which one is preferentially selected among the stocks that simultaneously satisfy the filtering condition.
For example, a-Z26 stocks are given a certain screening condition such as "stock price > -10 m", resulting in result sets a, B, C, D, a-D closing prices of 40, 30, 10, 20, respectively. And then setting the sorting condition as sorting according to the stock price from high to low, wherein the priority order of the recommended individual stocks is A > B > D > C, namely the individual stocks are sequentially pushed according to the order of A-B-D-C in actual operation. (the screening conditions and the sorting conditions in this example are only simple examples, and actually would be a combination of conditions.)
In addition, the stock selection strategy needs to consider several risk factors at the same time: individual stock liquidity, non-systematic risk (debarkation, pledge, business risk), i.e., the predetermined risk factors include, but are not limited to, individual stock liquidity, non-systematic risk (debarkation, pledge, business risk), etc.
And performing historical data back test on the stock selection strategy on the basis.
In this embodiment, the backtesting model performs historical backtesting on the second stock data according to a configurable first backtesting strategy to obtain a first historical backtesting result; and evaluating the first historical retest result according to at least one evaluation index, and correspondingly adjusting and updating the screening condition or/and the sequencing condition until the retest model is switched from the retest state to the working state when the first historical retest result output by the retest model meets a first expected condition.
In this embodiment, as shown in fig. 4, the retest model preferably employs a periodic rotation model. In the periodic rotation model, simulation conditions such as a bin adjustment period, a bin adjustment time point, a maximum bin holding quantity, a maximum bin position of each strand and the like need to be determined.
Wherein, as shown in fig. 5, the first test strategy comprises a plurality of combinations of test-back time, revenue benchmark, transaction cost and exclusion time period.
In this embodiment, the evaluation index includes a plurality of combinations of a total income evaluation index, a preset key evaluation index, and a positive correlation evaluation index; the preset key evaluation indexes comprise various combinations of sharp rate, maximum withdrawal rate, executable rate and income fluctuation rate.
In this embodiment, one way of evaluating the first historical return result according to at least one evaluation index includes:
judging whether the total income of the first historical return test result is greater than a total income evaluation index: if not, judging that the first historical return test result does not accord with the evaluation index;
if yes, continuously judging whether the key evaluation index of the first historical return test result meets a preset key evaluation index:
if not, judging that the first historical return test result does not accord with the evaluation index;
if yes, continuously judging whether the ranking condition and the income of the first historical return test result meet positive correlation evaluation indexes:
if not, judging that the first historical return test result does not accord with the evaluation index.
And if so, judging that the retest result meets the evaluation index.
In this embodiment, the first expected condition includes: multiple combinations of predetermined time wins (e.g., next day, 3 day, 5 day wins), yield (how much the rise and fall), maximum fall, and maximum gauging back depth (typically gauging back depth not exceeding 7%).
By backtesting the historical data of stock trading over a longer historical period, it is verified that a daily-based stock-selection strategy can theoretically yield positive benefits and properly combat non-systematic risks.
FIG. 6 shows historical data of a stock strategy based on the sun for a short line on a line. As shown in fig. 6, in the 5-year survey interval, the average profitability of the key indexes is 0.88%, the profit and profit are 52.19%, the profit and loss ratio is 5.88% to-4.57%, namely 1.287:1, and the executable proportion of the bin-adjusting instructions reaches 98.1% (almost no unexecutable transactions), and all indexes show that positive profit can be obtained on the stock-selecting strategy.
In this embodiment, after the review model enters the working state, the recommendation model selects, according to a configurable real-time push policy, a third stock of ticket data that meets the real-time recommendation condition from the second stock of ticket data to push and output.
Specifically, in this embodiment, as shown in fig. 7, the real-time pushing policy in the recommendation model includes:
calculating one or more push times for pushing the stock;
and judging whether stocks meeting the pushing conditions in the real-time disk exist in second stock data of the day before the day, if so, pushing the stocks to the user terminal, and if not, selecting corresponding stocks according to the ordering of the stocks in the second stock data to push the stocks to the user terminal when the pushing time is up.
When the conditions required by pushing in the disk are met (such as the real-time volume ratio of the current day is greater than 1.5), directly pushing a stock; when the conditions required by pushing in the disk are not met all the time, when the forced pushing time point calculated in advance arrives, the stocks with the highest scores are pushed out according to the sorting conditions (scores).
In this embodiment, after opening the stock on the second day, the corresponding stocks are sequentially selected from the stock pool in time-sharing mode to be pushed, so that the risk problem is mainly solved, firstly, the stocks can be recommended in time-sharing mode, the condition that the stock trend is influenced due to the fact that users buy the stocks too intensively and consistently is avoided, secondly, the combination condition of the stock-crossing data is difficult to manually judge which stock is recommended in a practical experience due to the fact that the recommendation rule in the stock pool is a series of time-sharing mode, and the A stock is a transaction mechanism of T +1, so that the risk that internal related personnel buy the stocks in advance to establish the rat chamber can be avoided by sequentially selecting the corresponding stocks from the stock pool in time-sharing mode after opening the stock on the second day.
Specifically, in the present embodiment, whether to execute the real-time push policy is controlled by a push probability function satisfying the push condition in the real-time disk. The push probability function is a monotonous function of the real-time comprehensive expansion amplitude, the distance market-receiving time and the push probability of each strand.
Suppose that the set latest recommended time is T0If the current time is T, then T0-T is the latest recommended time Δ T, and when Δ T is 0, selecting the corresponding stock from the second stock data and pushing the stock to the user terminal; and when the real-time comprehensive amplitude of each strand is smaller than the amplitude limit value, stopping executing the real-time pushing strategy.
The probability P that a stock is pushed by satisfying the push condition in real-time disk can be expressed as a function: p ═ F (T, R), there are two arguments:
1) the time is set to be T from the disk opening time, and T > is 0.
2) And (4) large-disc representation, setting real-time comprehensive expansion of two market stocks as R.
The disc opening time is set as a, and the disc closing time is set as b. The threshold for stopping pushing of R is S, and the graph shown in fig. 8 can be obtained.
The closer to market, the larger T and the larger P. As R becomes larger (the better the market), the criteria of the push requirement are more easily satisfied, and P rises. Conversely, when R becomes smaller, the market becomes worse and P decreases. When R < ═ S, the push stops completely. Therefore, in the ab interval, P and T, R have a monotonically increasing relationship, i.e. P is a monotonicity function.
Monotonicity interpretation of the function: monotonicity (monotonicity) of a function is also called as the increase and decrease of the function, and can qualitatively describe the relationship between the change of a function value and the change of an independent variable in a specified interval. When the argument of the function f (x) increases (or decreases) within its defined interval, the function value also increases (or decreases), and the function is said to be monotonous (monotonically increasing or monotonically decreasing) over that interval.
In particular, in this embodiment, the backtesting model performs a backtesting on the third stock of ticket data according to a configurable second backtesting policy to obtain a second historical backtesting result; the retest model judges whether the second historical retest result meets a second expected condition, and if so, the retest model does not act; and if not, the retest model is switched to the retest state from the working state when the state switching condition is met.
In this embodiment, the second retest strategy is as follows:
calculating the minimum price of each stock in the stock pool on the current recommended day, comparing the minimum price with the closing price of the previous day corresponding to the recommended day, and outputting a comparison result, namely a second historical return result;
and confirming whether the income obtained by buying the stock in the disk meets a second expected condition according to the second historical return test result, wherein the second expected condition is but not limited to: the probability of whether the profit gained by buying the stock in the disk is larger than the price of the stock in the second stock data selected according to the stock-selecting strategy; if so, a second expected condition is met; if not, the second expected condition is not satisfied.
As shown in fig. 9, the push time is a plurality of times, but not limited to, morning, noon, and evening hours. It should be noted that since the early disc distance is short per day, especially the last few minutes of disc opening such as volume ratio, and the fluctuation of the drive data such as buying, selling and the like is very large, if the drive data is used in the disc recommendation rule, the recommendation is generally prone to be performed after the disc is opened for a certain time such as 15 minutes; the luncheon disk has enough data volume and does not need to be carried out after 15 minutes. The recommended opportunity is therefore a difference between the morning and lunch recommendation rules.
In this embodiment, the main mechanism of the push condition in the real-time disk is shown in fig. 7. After opening the disc, one or several time points are fixed. And (4) pushing stocks which meet the real-time pushing condition before the time point. If not, pushing according to the sorting condition when reaching the time point.
In this embodiment, the real-time in-disk push condition is mainly based on the following factors: index rise and fall amplitude, individual strand rise and fall amplitude, disc opening information and the like. The purpose of judging the index fluctuation amplitude is to partially avoid systematic risks and stop stock recommendation when the index has a small-probability fluctuation event.
Generally, historical data retrieval of a stock selection rule in a tray based on individual stock fluctuation amplitude and tray opening information conditions needs to be based on a large amount of historical time-sharing data, and the method is very difficult to realize. However, the angle of the problem can be changed, and in the case that the data of the stock-selecting strategy return measurement based on the daily line is ideal, only the lowest price of the recommended day needs to be calculated and compared with the previous closing price of the recommended day, so as to confirm how much probability of buying in the disk can obtain the price which is better than the strategy based on the daily line.
In this example, the half-year data of 2019/6/3-2019/12/3 after the fact that a strategy stock pool is online is used for verification, and it is found that in 405 recommended records, 375 records have the lowest price of the following 1 trading day lower than the closing price of the day before recommendation, and account for 92.6% of the total proportion of all samples. It can be considered that push-in-disk does not significantly reduce profitability.
The stock transaction is divided into three links of buying, holding and selling, and the processes of the method only surround the link of buying. The remaining two important links, holding and selling, are manually judged by most individual investors. In order to provide a more objective and consistent operation methodology for users, it is also of positive significance to make explicit the ending of filling and losing while recommending stocks.
In this embodiment, the recommendation model pushes the determined ending surplus price and ending loss price while recommending the stocks to the user terminal; and the return test model carries out return test on the determined stop loss price and the stop loss price, and determines whether the currently pushed stop loss price and stop loss price are suitable.
Specifically, in this embodiment, one implementation manner of determining the stop filling price and the stop loss price includes:
respectively calculating the total number of profit trades and the total number of loss trades of the stock trading history data of the stock according to the stock selection strategy; respectively calculating the average income of the stock profit transaction and the average income of the loss transaction according to the total number of the profit transaction and the total number of the loss transaction; determining a loss value near 1 standard deviation according to the distribution of the maximum loss of all stocks, determining the loss value as a reserve price, and reversely pushing a minimum reserve value required for realizing profit according to a profit-loss ratio, and determining the minimum reserve price.
For example, there are 1000 transactions in a given time period, with 400 profits, 600 losses, and a profit-loss ratio of 40/60-1: 1.5. The average profit of 400 profit transactions is 10%, the average profit of 600 loss transactions is-5%, theoretically the total profit is 400 × 10% +600 × 5% — 1000%, and the average profit of a single transaction is 1000%/1000 ═ 1%.
According to the calculated profit-loss ratio of 1:1.5, if profit is to be realized, the filling/loss should be at least greater than 1.5, i.e. the filling should be at least greater than 1.5 x% at the loss-stop position.
Table 1 is the share of a stock-picking strategy where the deficit reaches the specified value within 5 days.
As shown in fig. 10, 31.2% of the stocks in the sample reached-4%, i.e., 68.8% of the stocks did not reach-4% of the stocks in the 5-day period, and was just around 1 standard deviation (if the statistics were normal distribution). It is reasonable to set the stop loss at-4%. Meanwhile, according to the profit-loss ratio, the thrust must exceed 6%, and is assumed to be 7%.
In this embodiment, for example, after the ending loss is determined, the final profit for all stocks is controlled to be-4% -7%. And finally, calculating the average profit according to the recalculated final profit to finally determine whether the profit can be realized by the strategy after the filling and the loss stopping are added.
The natural rate of return and the rate of return distribution map 11 and fig. 12 for setting the stop-filling and stop-loss are shown with 5 days as a trading period, and the rate of return is converged to some extent.
Therefore, the stock selection strategy of the stock pool in the embodiment is supported by historical backtesting, the probability of profit is high, corresponding stocks are selected from the stock pool and pushed to the user terminal in time intervals in sequence after the stock pool is opened on the second day, and the stocks can be recommended in time intervals, so that the situation that the stock buying is too concentrated and consistent by the user and the stock buying trend is influenced is avoided.
The embodiment also provides an intelligent stock recommendation method based on the remeasurement data, which comprises the following steps: a step of back test and a step of real-time push.
1) The back measurement step comprises:
screening the current stock data according to a configurable screening strategy, and outputting first stock data meeting screening conditions; sorting the first stock data meeting the screening condition according to a configurable sorting strategy, and outputting second stock data which meet the sorting condition and are sequentially arranged; performing historical backtesting on the second stock data according to a configurable first backtesting strategy to obtain a first historical backtesting result; and evaluating the first historical retest result according to at least one evaluation index, and correspondingly adjusting and updating the screening condition or/and the sequencing condition until the retest model is switched from the retest state to the working state when the first historical retest result output by the retest model meets a first expected condition.
2) The real-time pushing step comprises the following steps:
after the retest model enters a working state, selecting third stock of ticket data meeting real-time recommendation conditions from the second stock of ticket data according to a configurable real-time pushing strategy to carry out pushing output; carrying out retesting on the third stock of ticket data according to a configurable second retesting strategy to obtain a second historical retesting result; judging whether the second historical retest result meets a second expected condition, if so, not acting; and if not, the retest model is switched to the retest state from the working state when the state switching condition is met.
