What problem does it solve? Investors waste time researching companies that fail basic quality checks. This Skill applies seven hard financial indicators (ROE, free cash flow, interest coverage, gross margin, cash conversion, net margin, share dilution) to quickly eliminate companies that do not meet first-tier standards before any deep research begins. ## Core Features & Use Cases - Seven-Indicator Screening: Tests 10-year average ROE, 5-year cumulative FCF, interest coverage, gross margin, OCF/net income ratio, net margin, and share dilution against fixed thresholds. - Three Exemption Rules: Applies strategic-investment, low-margin-by-choice, and high-turnover exemptions so quality companies like early-stage Amazon or Costco are not wrongly excluded. - Batch Modes: Screens individual stocks, entire industries, index constituents, or thematic baskets, with pass-rate statistics and sector comparisons. - Use Case: Ask to screen the China beer industry, and receive a summary table marking each listed company as passed, excluded, or exempted, plus an SVG chart ranking companies by 10-year average ROE. ## Quick Start Run the quality screen on Tencent, Meituan, and Nvidia and show which companies pass all seven indicators.
