What problem does it solve?

It helps you analyze stocks, businesses, and investment opportunities by applying Warren Buffett’s complete decision system—so you can judge business quality, intrinsic value, and buy/hold/sell actions with disciplined consistency.

Core Features & Use Cases

  • Buffett-style Trigger & Scope Control: Activates when the user discusses stock/company analysis, financial reports/annual reports/shareholder letters, moats/competitive advantage, management integrity, buy/hold/sell decisions, value investing concepts, industry analysis, capital allocation, market sentiment/macro risks, and sell timing.
  • Two-Path Workflow: Runs a Quick Filter first for fast go/no-go decisions, then proceeds to deeper analysis paths for full company evaluation.
  • Decision-Ready Output Structure: Produces a complete, checklisted assessment covering circle of competence, assumptions, business quality (moat + management + model), financial snapshot (e.g., owner earnings, ROIC targets), valuation (intrinsic range + margin of safety), explicit sell criteria, risks, monitoring indicators, and an overall recommendation.

Quick Start

Use the buffett skill to evaluate whether a specific company is a buy, hold, or sell based on moat, management integrity, intrinsic value, and margin of safety.

FAQPage Schema
How do I analyze a stock using Warren Buffett's investment criteria?

Buffett-style investment analysis runs a quick red-flag filter followed by a structured deep-dive across business moat, management integrity, financial metrics, and intrinsic valuation to produce explicit buy, hold, or sell decisions with a defined margin of safety.

What is owner earnings and how does it factor into intrinsic value calculation?

Owner earnings are a financial metric used in intrinsic value calculation to measure the cash a business generates for shareholders. Buffett-style investment analysis uses owner earnings alongside ROIC targets to assess financial quality and establish a valuation range with a margin of safety.

When should I sell a stock to avoid a value trap?

You should sell a stock to avoid a value trap when specific risk-based sell conditions are met, such as deteriorating business fundamentals or management behavior changes. Buffett-style analysis monitors value-trap and risk-behavior criteria to establish explicit sell-timing rules during the initial evaluation.

How do I evaluate management integrity and business moat from annual reports?

To evaluate management integrity and business moat from annual reports, you analyze shareholder letters and financial statements for competitive advantage indicators and capital allocation decisions. Buffett-style analysis interprets these documents to assess governance, business model durability, and management behavior within your circle of competence.

Can I use Buffett-style investment analysis for industry analysis and macro risk assessment?

Yes, Buffett-style investment analysis applies to industry analysis and macro risk assessment by using optional industry playbooks and evaluating market sentiment risks. The framework assesses business quality, capital allocation, and sell-timing conditions within the context of specific industry dynamics and broader market risks.
