Quantitative Models and Construction Methods - Model Name: Method 1 - "Consumption-Manufacturing-Technology" Investment Mainlines Model Construction Idea: This model draws on the experience of segmenting the pharmaceutical sector and applies a three-pronged investment approach to position electronic enterprises along the axes of consumption, manufacturing, and technology[3] Model Construction Process: The model categorizes electronic companies based on their alignment with the three investment mainlines, aiming to provide a clearer framework for stock selection in the electronics sector[3] Model Evaluation: This method provides a broad perspective but may lack the granularity needed for the electronics sector's diverse business models[3] - Model Name: Method 2 - Capital Intensity and Industry Lifecycle Segmentation Model Construction Idea: This model refines the segmentation of electronic enterprises by integrating capital intensity and industry lifecycle characteristics, classifying companies into three types: innovation-driven (light asset), growth-expansion (heavy asset), and mature-return (heavy asset)[3] Model Construction Process: 1. Assess the capital intensity of electronic enterprises to determine their asset-light or asset-heavy nature 2. Evaluate the lifecycle stage of the enterprise (e.g., innovation, growth, or maturity) 3. Combine these dimensions to classify companies into the three categories mentioned above[3] Model Evaluation: This method better captures the manufacturing attributes and diverse business models of the electronics sector, making it more suitable for stock selection in this industry[3] Model Backtesting Results - Method 1: No specific backtesting results provided in the report[3] - Method 2: No specific backtesting results provided in the report[3] Quantitative Factors and Construction Methods No specific quantitative factors were detailed in the provided content. Factor Backtesting Results No specific backtesting results for factors were detailed in the provided content.
