What it does

When you name an industry or investment theme, this skill tells the agent to scan the whole market for candidate companies (including Chinese, Hong Kong, US and some unlisted firms), filter them through five value-investing tests such as valuation, return on equity, cash flow, debt ratio and moat strength, then write a detailed report on the final three. Every rejected company must be logged with a reason, and the report includes position-sizing suggestions and a data-accuracy check. It is a structured research workflow, not a source of real-time market data by itself.

Great for

  • Investors who want a repeatable, documented process for researching a sector
  • Analysts who want a checklist-driven funnel that records why companies were dropped
  • Students learning how value-investing screens are structured

Skip it if

  • People looking for guaranteed or personalised buy/sell advice: the output is AI-generated research, not a licensed recommendation, and can contain errors or stale figures
  • Users who need verified live financial data: the skill relies on the agent's web search and the user's own sources, and the file itself does not guarantee data accuracy
  • Short-term traders, since the framework is long-term value investing

Try asking

  • “Run the industry funnel on AI computing power and list the top three candidates”
  • “Screen the humanoid robot sector across A-shares, Hong Kong and US stocks”
  • “Do a value-investing funnel on innovative drug companies and log every rejected firm with its reason”

    Ask for the task

    No special command needed — the agent reads the skill's description and loads it when your request matches. Try one of the prompts above.

Get better results

  • Name a specific industry or sub-sector, such as 'AI computing power' rather than 'technology', so the screen stays focused
  • Check every figure the agent cites against the original filings, since the skill itself says estimates must be labelled and verified
  • Treat the three final picks as a starting point for your own research, and read the risk and bear-case sections closely
