Group 1: Yi Rating Overview - "Yi Rating" is positioned as a foundational infrastructure for investment research in the AI era, with the goal of enhancing pricing efficiency in China's capital markets [3]. - The deep research rating evaluates companies based on long-term value criteria, including growth potential, profit expectations, industry landscape, and competitive moats [3][4]. - The three rankings are designed to identify high-quality companies with long-term growth potential amidst a noisy capital market [3][4]. Group 2: Evaluation Criteria - The evaluation framework combines qualitative and quantitative methods, covering various dimensions such as business model rating, operational performance rating, deep research rating, trading rating, and risk rating [4]. - The "Most Competitive Moat" ranking focuses on companies' sustainable competitive advantages, which help them withstand market fluctuations and maintain operational stability [4]. - The moat evaluation includes both "moat width" and "moat sustainability," incorporating both qualitative assessments and quantitative measurements of excess profits [4].
