Preface

Researchers covering A-shares often face an awkward dilemma: a single valuation method cannot handle all companies. For traditional enterprises, “Lao Tang’s Valuation Method” (three prerequisites plus P/E ratio) works well enough, but when encountering tech stocks or asset-light companies, the logic regarding Free Cash Flow (FCF) and discount coefficients requires switching to a different framework. Running these two methods separately leads to mismatched conclusions and makes report integration impossible.

The Skill “Lao Tang’s Valuation Pro” introduced below solves this problem. It executes both Lao Tang’s Valuation Method and “New Tang’s Valuation Method” simultaneously within a single workflow. After inputting a stock code, it automatically fetches financial data and generates a single report containing judgments from both frameworks.

What is this

Lao Tang’s Valuation Pro is a community Skill on SkillHub, located at @user_aa5220ea/tang-valuation-pro. It falls under the “professional” category, is currently at version 2.0.2, and requires an API Key configuration (tagged requires_api_key=true). According to a SkillHub page snapshot, it has a rating of 100,000 and 1,182 downloads; specific figures should refer to the real-time display on the official page.

It solves the following problem: given an A-share code, it outputs a complete valuation analysis report, rather than forcing the user to manually switch back and forth between two distinct valuation frameworks.

Core Features

The verified capabilities are as follows:

  1. Dual-Track Valuation. Runs Lao Tang’s Valuation Method and New Tang’s Valuation Method simultaneously. Lao Tang’s method utilizes the three prerequisites plus P/E valuation for traditional enterprises, while New Tang’s method employs discount coefficients plus Free Cash Flow for tech stocks. Both analyses execute in parallel, with each producing its own set of buy-point and sell-point judgments within the report.
  2. Automated Data Fetching. Upon inputting a stock code, the AI automatically retrieves financial data. Users do not need to manually organize financial statements before feeding them into the model.
  3. Master’s Perspective. Built-in first-person analyses from three masters: Warren Buffett, Charlie Munger, and Duan Yongping. This provides an additional layer of perspective beyond the dual-track conclusions.
  4. Comparison & Tracking. Supports comparative analysis of two enterprises and summary tracking of historical valuations. Users simply input the codes for 1 to 2 A-share companies.

Installation & Activation

Installation commands and directory conventions from the official page were not provided in the retrieved materials, so no speculation is made here. To install, please open the official URL:

Since this Skill carries the requires_api_key=true tag, a valid API Key must be prepared and configured according to the official instructions before activation. Specific integration methods (SkillHub, Cursor, Codex CLI, or Claude Code) should follow the official page; this article makes no assertions regarding them.

Typical Usage

The most direct usage is to provide a single A-share stock code. For example, inputting a traditional enterprise or a tech company code allows the Skill to automatically complete data fetching, dual-track analysis, and master’s perspective breakdowns, finally outputting a complete valuation report.

When two codes are input, it follows a comparative analysis path: it calculates two sets of valuation conclusions separately and then aggregates them into a comparison table, useful for horizontal comparisons of targets within the same industry or track.

For summary tracking of historical valuations, the usage involves placing multiple valuation results for the same target together to observe how buy/sell point judgments change over time.

Use Cases & Caveats

Suitable scenarios: Determining buy/sell points for A-share stocks, switching valuation frameworks between traditional and tech companies, horizontal comparisons of dual targets, and historical tracking of valuation results.

Clearly not applicable: Trend analysis, K-line (candlestick) timing, Hong Kong/US stock valuations, and analysis of unlisted companies. Please use other tools for these scenarios and do not force calculations with this tool.

Two points to note: First, the Skill relies on automated data fetching and API Keys; analysis will be interrupted if data fetching fails or the Key is misconfigured. Second, the coexistence of dual-track conclusions means the report may contain inconsistencies between the two sets of judgments. This is normal output; final decisions must still be made by the user. Do not treat the report as a single definitive answer.

Conclusion

The value of Lao Tang’s Valuation Pro lies in compressing two valuation frameworks into a single workflow, eliminating the repetitive labor of manual switching and data organization. It is suitable for developers or researchers requiring comprehensive valuation analysis of A-share stocks.
