SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve? It turns a vague investment theme into a structured, decision-ready industry research report, avoiding the vague "on one hand, on the other hand" analysis that generic AI answers produce. ## Core Features & Use Cases - Investment Logic Chain Validation: Maps the causal chain from macro trend to beneficiary companies and verifies each link with real signed deals and evidence. - Global Company Scanning: Scans A-share, Hong Kong, US, and international listed companies plus pre-IPO players, tiered by purity and market cap. - Four-Master Analysis: Applies Duan Yongping, Buffett, Munger, and Li Lu frameworks to each tier-1/tier-2 company, covering moat scoring, risk inversion, management review, and valuation snapshots. - Use Case: Ask it to research the nuclear power industry and receive a full value-chain map, company tiers, portfolio allocation with position sizing, buy/sell signals, and a data-audited Markdown report. ## Quick Start Ask the agent to run an industry investment research report on the solid-state battery industry with global company coverage and portfolio recommendations.

Frequently Asked Questions about industry-research

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I research an industry value chain for investing?

Provide an industry or investment theme as the argument, and the workflow builds a causal logic chain, maps upstream to downstream segments, scans global listed companies, and analyzes tier-1 and tier-2 firms with a four-master framework.

What stock markets does this industry research cover?

It scans US exchanges (NYSE, NASDAQ), A-shares (Shanghai, Shenzhen), Hong Kong stocks, and other international markets such as Japan, Korea, Europe, and Australia, plus industry ETFs and key pre-IPO companies.

How does the four-master investment analysis framework work?

Each leading company is scored on business quality (Duan Yongping), moat strength across five types (Buffett), failure scenarios and inversion risks (Munger), and long-term certainty (Li Lu), producing a 1-5 star recommendation rating.

Does the research report include portfolio allocation advice?

Yes, it outputs a tiered portfolio with core, satellite, and option positions, an ETF alternative, buy/sell/exit signals, and a suggested cap on the theme's share of total portfolio.

How is financial data accuracy verified in the report?

After writing the report, a data audit step runs tools/report_audit.py to extract a 15 percent random sample of claims, re-verify each against reliable sources, and issue a pass or reject verdict before publication.

What are the limitations of AI-generated industry research?

The skill explicitly flags biases such as preference for mature industries, large caps, and English sources. It labels each company with an information sufficiency grade (A/B/C) and marks uncertain conclusions as gray zones rather than fabricating confidence.
