Group 1 - The gold market has seen a recent surge, with gold futures reaching a historic high of $3534.1 per ounce, driven by expectations of interest rate cuts by the Federal Reserve and geopolitical uncertainties [1][2] - Analysts suggest that the investment logic for gold stocks is shifting from focusing on short-term production growth to emphasizing companies with larger reserves, as the consensus for long-term gold price increases strengthens [1][2] - Central banks are expected to continue increasing their gold reserves, with China's reserves rising to 73.96 million ounces as of July, marking nine consecutive months of increases [3][4] Group 2 - The World Gold Council reported that while central bank gold purchases slowed in Q2 2025, the volume remains 41% higher than the average from 2010 to 2021, indicating sustained high levels of demand due to geopolitical and economic uncertainties [4] - Institutions remain optimistic about long-term investment opportunities in gold, with expectations that interest rate cuts and geopolitical factors will support gold prices, thereby influencing the investment focus towards companies with stable, large-scale gold mines [5][6]

Group 1: CPI Analysis - In July, the Consumer Price Index (CPI) increased by 0.4% month-on-month, reversing a previous decline of 0.1%, and remained flat year-on-year, with core CPI (excluding food and energy) rising by 0.8% year-on-year, marking a continuous expansion for three months [1][2] - Food prices decreased by 0.8% year-on-year, contributing to a decline of approximately 0.21 percentage points in CPI, while other categories such as transportation, education, and healthcare saw increases [2][3] - The performance of CPI in July was better than seasonal expectations, driven by rising prices in services and industrial consumer goods [2] Group 2: PPI Insights - The Producer Price Index (PPI) decreased by 0.2% month-on-month, but the decline was narrower than the previous month, marking the first contraction reduction since March [4] - The reduction in PPI was primarily observed in upstream industries, with significant improvements in coal, steel, and photovoltaic sectors, indicating a positive impact from anti-involution policies [4][5] - The anti-involution measures are beginning to show effects, leading to a stabilization and potential recovery in prices across various industries [4][5] Group 3: Economic Outlook - Short-term effects of anti-involution policies are expected to reshape supply-demand structures and enhance overall efficiency in the industrial chain, potentially leading to a reasonable price recovery [5] - The sustainability of price increases in the medium to long term remains uncertain, heavily dependent on policy execution and coordination across various sectors, including emerging industries like photovoltaics and electric vehicles [6] - The effectiveness of these policies in creating a virtuous cycle of improved corporate profitability and enhanced economic momentum hinges on the ability to stimulate domestic demand [6]

Report Summary 1. Investment Rating The report does not provide an industry investment rating. 2. Core View - **Market Fundamentals and Logic**: There are both positive and negative factors in the apple market. Positive factors include the potential for lower - quality new - season apples and the expectation of a high opening price. Negative factors are that the new - season apple production is basically the same as last year, the price of inventory apples is falling, and apple performance is average during the off - season. In August, the price of inventory apples in the production areas is stable, with a slightly improved but still slow出库 speed. The price of Crown pears shows a trend of low - opening, high - going, and then low - going. Early - maturing apples are on the market, and the price of new - season Fuji apples may be related to that of early - maturing and old - season apples [4]. - **Strategy Recommendation**: For the single - side strategy, it is recommended to lightly short the 2601 contract at a high position. For the inter - month strategy, it is recommended to go long on 2510 and short on 2601. There are no recommendations for volatility and options [4]. 3.

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]
