Getting Started

What makes this prompt different from other stock analysis tools?
This prompt replicates Warren Buffett's proven investment framework that has delivered 19.8% annual returns over 50+ years. It focuses on economic moats, management quality, and intrinsic value - not short-term price movements or technical indicators.
Can beginners use this prompt effectively?
Yes. The prompt guides you through each analysis step with clear questions. However, basic understanding of financial statements (income statement, balance sheet, cash flow) will help you interpret AI responses better.
What is the difference between this and traditional stock screeners?
Traditional stock screeners filter stocks by numerical criteria (P/E ratio, market cap, etc.). This prompt goes far beyond that by providing qualitative and quantitative analysis within Buffett's framework — evaluating economic moats, management integrity, competitive advantages, and intrinsic value. It delivers a holistic investment thesis, not just a filtered list.

How to Use

Which AI model should I use with this prompt?
GPT-4o, Claude Sonnet 4, or Claude Opus 4.5 work best. These models have stronger reasoning capabilities for complex financial analysis and can better apply Buffett's principles.
How often should I re-analyze a company?
Run analysis when: (1) Quarterly earnings are released, (2) Major company news or management changes occur, (3) Stock price drops significantly, offering a potential buying opportunity.
Can this prompt analyze non-US stocks?
Yes, this prompt works for any publicly traded company worldwide. Simply enter the company name and the AI will apply Buffett's framework. However, data availability may vary for non-US companies, and financial reporting standards differ (e.g., IFRS vs. GAAP), so always cross-reference with local regulatory filings.
How should I interpret the AI's output?
Treat the AI's analysis as a research starting point, not as a buy or sell signal. The output provides a structured framework for thinking about the company, but you should always cross-reference key metrics with actual financial data from official filings. Use the analysis to guide your own due diligence rather than relying on it as the sole basis for investment decisions.
