 ZHONGTAI SECURITIES· 2025-08-07 13:05
 Quantitative Models and Construction Methods  - **Model Name**: Floating Frequency Fourier Transform Model     **Construction Idea**: The model aims to overcome the limitations of traditional Fourier analysis by introducing floating frequencies, which adapt to real-world market dynamics such as macroeconomic changes and capital structure shifts[64][65][66]     **Construction Process**:     1. **Filtering**: Use Butterworth filter to remove high-frequency noise and retain trend data. The filter is applied to the logarithmic weekly closing prices of the Shanghai Composite Index, with cutoff frequency set at 0.1 and sampling frequency at 1.0[65][67]     2. **Frequency and Amplitude Selection**: Perform discrete fast Fourier transform on filtered data to extract amplitude and phase information. Key frequencies are identified based on amplitude peaks, e.g., 94.1 weeks, 80.5 weeks, and 62.6 weeks[75][78]     3. **Waveform Reconstruction**: Combine selected frequencies and amplitudes to reconstruct the market trend curve. The reconstructed curve includes direct current components and sinusoidal terms with specific frequencies and initial phases[68][78]     **Evaluation**: The floating frequency approach improves prediction accuracy by preserving real-world frequency characteristics and reducing extrapolation errors[64][65][66]    - **Model Name**: Dual Optimization Floating Frequency Fourier Transform Model     **Construction Idea**: Enhance the floating frequency Fourier transform by optimizing both amplitude and frequency to better fit market trends and improve prediction accuracy[85][86][87]     **Construction Process**:     1. **Inner Optimization**: Use non-linear least squares to optimize amplitude values (sin and cos terms) for given initial frequency values. Frequencies are combined with the top two amplitudes from Fourier transform results to form a fitting curve[87][88]     2. **Outer Optimization**: Apply particle swarm optimization to determine the best floating frequencies (e.g., 39.02 weeks, 19.17 weeks, and 8.13 weeks). Training data spans 10 years (2014-2024), and the model is validated using 2024-2025 data[87][88][100]     **Evaluation**: The dual optimization method significantly improves trend accuracy compared to simple floating frequency models, especially in capturing major market movements[85][86][100]     Model Backtesting Results  - **Floating Frequency Fourier Transform Model**:     - Key frequencies: 94.1 weeks, 80.5 weeks, 62.6 weeks[78][80][81]     - Observed discrepancies in certain periods, e.g., 2014-2015 and 2017-2019, indicating limitations in amplitude selection methods[81]    - **Dual Optimization Floating Frequency Fourier Transform Model**:     - Optimized frequencies: 39.02 weeks, 19.17 weeks, 8.13 weeks[100]     - Improved accuracy in major trend predictions, e.g., capturing relative highs in September 2021[100]     - Future predictions: Long-term upward trend from 2024 to 2027, with key oscillations in August 2025 and August 2026[102][103]     Quantitative Factors and Construction Methods  - **Factor Name**: Harmonic Sine Wave Factor     **Construction Idea**: Simulate price movements using harmonic sine waves to replicate Elliott Wave patterns[39][42]     **Construction Process**:     - Formula: $y(n) = 4*sin(0.00125n)+2*sin(0.01n)+1*sin(0.04n)+0.5*sin(0.16n)$     - Variables: $n$ represents time, $y(n)$ represents price index     - Frequency structure: Base frequency 0.00125, harmonic frequencies follow $2^k$ relationship (k=-3,0,2,4)     - Amplitude decay: Coefficients follow $2^{-m}$ rule (m=-1,0,1,2)[39][42]     **Evaluation**: Successfully replicates 5-3 wave patterns described in Elliott Wave theory, providing a mathematical basis for wave analysis[39][42]    - **Factor Name**: Pletcher Fibonacci Wave Factor     **Construction Idea**: Introduce quasi-periodic characteristics by incorporating non-harmonic frequencies into wave simulation[50][51]     **Construction Process**:     - Formula: $y(n) = 4*sin(0.00125n)+sin(0.01n)+1/2*sin(0.04n)+1/4*sin(0.17n)+1/8*sin(0.72n)+1/16*sin(0.305n)$     - Frequency relationships: Some frequencies maintain harmonic relationships (e.g., 0.00125, 0.01, 0.04), while others exhibit non-harmonic relationships (e.g., 0.17, 0.72, 0.305)[50][51]     **Evaluation**: Captures floating frequency characteristics and quasi-periodic behavior, aligning with real-world market dynamics[50][51]     Factor Backtesting Results  - **Harmonic Sine Wave Factor**:     - Successfully replicates Elliott Wave patterns, including 5-3 wave structures[39][42]    - **Pletcher Fibonacci Wave Factor**:     - Demonstrates quasi-periodic behavior, reflecting floating frequency characteristics in market data[50][51]

 债市“褪色”之后
 ZHONGTAI SECURITIES· 2025-08-06 10:18
 Report Industry Investment Rating - Not provided in the content   Core Viewpoints of the Report - The bond market lacks its own driving factors this year, with its fluctuations mainly influenced by external factors. The "endogenous" fluctuations of the bond market are converging, and it's difficult to change the "meager fluctuations" of this year's bond market. In the second half of the year, the bond market is expected to have narrow - range oscillations each month, and neither excessive short - nor long - positions are advisable [5][10][35]   Summary by Relevant Catalogs  1. 6 - month Bond Market's Expected "Old Script" - Since June, interest rates have been consolidating and oscillating, and fund durations have gradually increased, anticipating a downward trend in interest rates in July. The market was skeptical about the economic outlook despite good Q2 GDP data, expecting a neutral tone from the July Politburo meeting. As a result, in early July, the overall fund duration increased, and there was an expansion of credit - bond ETFs. In June, the net inflow of market - making credit - bond ETFs was 6.3314 billion yuan, a 146% increase from May. In mid - July, the Sci - tech Innovation Bond ETF took over the market, with an average duration of about 4.3 years and 3.9 years for the tracked indices [13]  2. New Developments in the Equity and Commodity Markets - Starting from June, the commodity and equity markets showed a completely opposite trend to the bond market, entering a trading mode with rapidly increasing risk appetite. Commodity prices rebounded from lows and then rose across the board, fully recovering the gap caused by the April tariff shock by July 22. The equity market reached new highs and continued to rise, spreading from bank dividends to low - valuation sectors in the technology sector and then to the cyclical sector. The bond market's expected scenario did not occur, and it started to adjust rapidly on July 21 [4]  3. Bond Market's Rise and Fall Driven by External Factors - The bond market has been in a narrow - range technical oscillation, with interest rates fluctuating around the central level by about 10 BP. Two major factors causing significant adjustments in the bond market are external: the unexpected escalation of trade frictions in April led to a sharp decline in bond interest rates, with the 10Y Treasury bond rate dropping from over 1.8% to 1.61% on April 7; the resonance of the equity and commodity markets in late July led to an accelerated upward movement of the 10Y interest rate, breaking through 1.70% [5][21]  4. The "Positive and Negative" Sides of the Convergence of Bond Market's Endogenous Fluctuations - On one hand, the yields of bond - based funds have declined, and the expected returns of bond - related assets need adjustment. As of August 1, the performance of pure - bond funds this year has been weaker than in 2024. On the other hand, the market's attention to bonds has significantly decreased. The trading volume of Treasury bond futures has not changed significantly, while the trading volume of coking coal contracts has increased. The "asset shortage" narrative in the bond market is also weakening, as insurance premium growth has slowed, rural commercial banks' trading volume has decreased, and the buying power of wealth management products for long - term bonds has weakened [24][25][26]  5. Main Themes in the Second Half of the Year - The market needs to find factors beyond the "stock - bond seesaw" effect. When the equity market stabilizes above 3500 points, it's necessary to consider the factors jointly influencing the stock and bond markets. The expectations, verifications, and adjustments of "anti - involution" will continue, and the market's understanding will change. The underestimated overseas and tariff factors may resurface. The most important factor for the bond market may be its own asset - liability changes. If the average annualized returns of bond funds and wealth management products are less than 1.5% by the end of the year, there may be a shift of deposits to riskier assets [8][30][33]
