1 introduction
The strategy team of China Securities Company is one of the important forces in China's securities market. Its main responsibilities are to analyze the macroeconomic situation and market environment, propose investment strategies and industry allocation suggestions, and provide customers with a full range of investment consulting services. Since the 1990s, with the continuous development and growth of China's securities market, the strategy team of securities companies has gradually emerged. The earliest securities company strategy group was mainly based on economic theory and quantitative analysis methods, and put forward investment suggestions by studying economic fundamentals and company financial data. With the continuous development of information technology, the strategy team of securities companies has gradually introduced new technologies such as big data and artificial intelligence to improve the efficiency and accuracy of research. In recent years, the rapid development of China's securities market and the promotion of reform and opening up policies have further strengthened the status and role of the strategy team of securities companies. More and more investors begin to rely on the investment advice of the strategy group to make decisions, which also promotes the professional and diversified development of the strategy group.
According to data from the Securities Association of China, as of the end of 2021, the strategy team of Chinese securities companies has covered more than 90% of securities companies, including more than 600 strategy analysts. In addition, as of the end of 2021, more than 8,000 institutional clients have opened strategic research services, and the coverage and influence continue to expand. According to statistics, in recent years, the research reports issued by the strategy groups of major securities companies have exceeded tens of thousands, forming a securities research report system with great market influence and becoming one of the important research forces in China's capital market.
In short, the strategy team of securities companies has played an important role in the development of China's securities market, not only promoting the development of the market, but also providing investors with important investment decision-making reference. However, whether its research report and industry configuration recommendations are really effective needs further exploration and evaluation. In this article, we will explore the judgment of the Securities Research Institute Strategy Group and the validity of the industry allocation, and how to deal with their opinions and suggestions.
2 Status of the Strategy Group of the Securities Research Institute
The strategy group of the securities research institute refers to a group of experts within the securities company, which is mainly responsible for formulating investment strategies and researching and analyzing information such as securities market conditions, industry trends and company performance, so as to assist customers to make correct investment decisions.

On the one hand, the analysis report of the strategy group may trigger an effect similar to public opinion in the investment community by exporting opinions to institutional investors and individual investors, thereby affecting the market. On the other hand, the analysis of the market by experts in the strategy group belongs to the top-level group in the securities market, and their analysis reports are usually in-depth and forward-looking. Therefore, if we can combine these analysts' judgments on market conditions and industry allocation suggestions to invest, we may be able to obtain considerable returns. This article upholds this point of view, and organizes the research reports released by the strategy groups of major brokerage research institutes on the WeChat public account platform every Sunday to form a weekly sentiment score, weekly industry configuration recommendations, and weekly market style configuration recommendations. Statistical data, and using data structuring factors, for backtesting.
3 The judgment of the strategy group and the validity of the industry allocation
3.1 The strategy group judges the accuracy of market conditions
Collected the reports sent by the strategy groups of major securities companies every weekend starting from 2021-08-16 (including Industrial Securities, GF Securities, Haitong Securities, Tianfeng Securities, China Merchants Securities, China Securities, Guosheng Securities, Minsheng Securities, Cinda Securities, CICC, Huaxi Securities, Essence Securities and Guojun Securities), extract core views and industry configuration data from them, and rate the sentiment of each report. This is a subjective score, with 1 being extremely pessimistic and 5 being Neutral, 10 is extremely optimistic. The picture below shows the core viewpoint extraction and sentiment scoring of the market strategy group for 20210816-20210822.
*It should be noted that due to the long duration of data collection, the data during 2022/9/26-2022/11/20 is missing, and the data from 2022/11/21-2023/3/19 has not been configured by industry statistics.
The study found that the rise and fall of the Shanghai and Shenzhen 300 Index next week is significantly positively correlated with the sentiment of the research report released by the strategy group on Sunday. The graph of the rise and fall of the Shanghai and Shenzhen 300 next week, sentiment judgment, and this week's sentiment changes is shown below .
Figure 1. The rise and fall of the Shanghai and Shenzhen 300 Index next week is significantly positively correlated with the sentiment of the research report released by the strategy group on Sunday
When the sentiment judgment score is high, the probability of the market rising next week is greater, and when the sentiment change is positive, the probability of the market rising next week is also greater.
Then build a strategy backtest, use sentiment changes as factors, hold the CSI 300 index portfolio when the sentiment changes are positive, and short positions when the sentiment changes are negative. The returns of the strategy relative to the CSI 300 are as follows.
Figure 2. The excess return of the Shanghai and Shenzhen 300 Index is positive after the strengthening
The dotted line box in the above figure belongs to the time period when the data is missing. The position during this period is the default short position. It can be seen that except for the sharp drop during this period, there is no sharp drop and retracement in other time periods. The excess return curve There is a clear upward trend. This shows that using the sentiment indicators reported by the strategy group over the weekend to build strategies can obtain excess returns in the market.
3.2 The effectiveness of the industry configuration of the strategy group and the effectiveness of the market style judgment
In addition to forecasting market trends, another important task of the strategy group is to make industry configuration recommendations. If we can carry out excellent industry allocation, or even only need to control the broader market style, we can continue to obtain more returns from the previous excess returns of the CSI 300.
Collected the industry configuration recommendations of the strategy group research reports of major securities companies every weekend starting from 2021-08-16, summarized them according to the first-level industry classification of Shenwan, and calculated the recommended industries belonging to different market styles and calculate the proportion. The figure below shows the recommended statistics of the market strategy group industry configuration for 20210816-20210822.
*It should be noted that due to the long duration of data collection, the data during 2022/9/26-2022/11/20 is missing, and the data from 2022/11/21-2023/3/19 has not been configured by industry statistics.
First, judge the effect of market style control, using 931447.CSI (Technology Pioneer), 510150.sh (Consumer ETF), 510650.sh (Financial Real Estate ETF) and 510110.sh (Cycle ETF) as the benchmarks of the four styles Market data, then build a strategy backtest, use the proportion of the style of the recommended configuration industry as a factor, hold the corresponding index or ETF when the proportion rises, and short the position when the proportion declines, the excess returns of the strategy relative to their respective benchmarks are as follows.
Figure 3. There is a significant positive correlation between the rise and fall of technology pioneers and the proportion of financial real estate in the recommended allocation industry
Figure 4. There is a significant positive correlation between the rise and fall of financial real estate ETFs and the proportion of financial real estate in the recommended allocation industry
Figure 5. There is a significant positive correlation between the rise and fall of financial real estate ETFs and the proportion of financial real estate in the recommended allocation industry
Figure 6. The rise and fall of cyclical ETFs is significantly positively correlated with the proportion of financial real estate in the recommended allocation industry
Figure 7. Excess return after index enhancement (super-corresponding index)
Figure 8. Excess return after index enhancement (exceeding CSI 300)
The dotted line box in the above figure belongs to the time period when the data is missing. The position during this period is the default short position. It can be seen that except for the sharp drop during this period, there is no sharp drop and retracement in other time periods. The excess return curve There is a clear upward trend. Moreover, the excess returns of three of the four styles of trading have exceeded the CSI 300.
In order to judge the effectiveness of industry allocation, the number of recommended industry allocations per week was counted and arranged from high to low, and then the backtest was constructed on the basis of rising sentiment (Figure 2 backtest results), and industry allocation was carried out, while No longer just buy the Shanghai and Shenzhen 300 index portfolio. The results of holding positions in 1 industry to 5 industries were tested respectively, and the top five industries every week are as follows.
