Quantitative Models and Construction Methods 1. Model Name: 300ETF Intelligent Investment Strategy - **Model Construction Idea**: This strategy uses the 300ETF index fund as the investment target. It adjusts the investment amount based on the valuation level of the PE ratio of the CSI 300 Index. The lower the valuation, the higher the investment multiple, and vice versa. When the valuation is extremely high, the strategy attempts to reduce or clear positions to avoid potential losses from valuation reversion[18] - **Model Construction Process**: 1. Divide the historical PE ratio of the CSI 300 Index into several valuation intervals based on its mean and standard deviation 2. Determine the investment multiple for each interval: higher multiples for lower valuations and lower multiples for higher valuations 3. Adjust the investment amount dynamically based on the current valuation level[18] - **Model Evaluation**: The strategy demonstrates better excess returns and risk control compared to the 300ETF benchmark[20] 2. Model Name: 300ETF Intelligent Investment and Covered Call Strategy - **Model Construction Idea**: This strategy builds on the intelligent investment strategy by adding a covered call component. When the market is in a long-term oscillation phase, it opens covered call positions to earn option premiums and enhance returns[19] - **Model Construction Process**: 1. Hold 300ETF spot positions based on the intelligent investment strategy 2. During long-term market oscillations, sell 300ETF call options to collect premiums 3. Adjust the strategy dynamically based on market conditions[19] - **Model Evaluation**: The strategy achieves higher excess returns and better risk control compared to the 300ETF benchmark[25] 3. Model Name: Support Vector Machine (SVM) Timing Strategy - **Model Construction Idea**: The SVM model, a supervised machine learning algorithm, is used to predict market trends for the CSI 300 Index. It utilizes 12 indicators as feature vectors to classify and forecast market movements[29][30] - **Model Construction Process**: 1. Select 12 indicators as feature vectors: turnover rate, ADTM, ATR, CCI, MACD, MTM, ROC, SOBV, STD26, STD5, margin trading volume as a percentage of A-share turnover, and previous week's return rate 2. Train the SVM model using historical data to classify market trends into "buy" or "sell" signals 3. Implement the strategy: - For "buy" signals: execute long positions in both single-direction and dual-direction strategies - For "sell" signals: single-direction strategy exits positions, while dual-direction strategy takes short positions[30] - **Model Evaluation**: The SVM model demonstrates effectiveness in market timing, achieving significant excess returns and lower drawdowns compared to the CSI 300 Index[31][32] --- Model Backtesting Results 1. 300ETF Intelligent Investment Strategy - **Final Net Value**: 0.96 - **Annualized Return**: -1.00% - **Annualized Volatility**: 16.78% - **Maximum Drawdown**: 22.39% - **Sharpe Ratio**: -0.24[24] 2. 300ETF Intelligent Investment and Covered Call Strategy - **Final Net Value**: 0.96 - **Annualized Return**: -1.12% - **Annualized Volatility**: 17.22% - **Maximum Drawdown**: 19.61% - **Sharpe Ratio**: -0.25[27] 3.

Investment Rating - The industry investment rating is "Overweight" [2] Core Viewpoints - The recent production halt by BASF due to an incident has led to a supply shortage of Vitamin A and E, which are critical in the feed industry. This is expected to drive prices up and improve market conditions for these vitamins [2] - The recovery of pig farming profits is anticipated to boost the demand for vitamins, particularly as pig feed constitutes the largest portion of total feed production in China [2] - As of August 9, 2024, the wholesale price of live pigs has increased by 42% since the beginning of the year, which is expected to further enhance the profitability of pig farming and consequently the demand for vitamins [2] Summary by Sections Industry Performance - The global market for Vitamin A has only seven producers, with BASF holding a 26.7% market share, while Vitamin E has five producers with BASF holding a 13.8% share. This concentration indicates a potential for significant supply disruptions [2] - Recent maintenance shutdowns at other vitamin production facilities are expected to exacerbate supply constraints [2] Price Trends - As of August 9, 2024, Vitamin A prices reached 210 RMB/kg, and Vitamin E prices reached 150 RMB/kg, marking increases of 132% and 62% respectively since July 29, 2024. Year-to-date, these prices have surged by 190% and 152% [2] - The low proportion of vitamin costs in feed means that downstream industries are less sensitive to price increases, suggesting that demand may remain robust despite rising costs [2] Investment Recommendations - Given the supply gap created by BASF's production halt and the anticipated increase in demand due to improved farming profitability, the outlook for Vitamin A and E is positive, warranting an "Overweight" rating for the industry [2]
