Philip Fisher
Pioneer of Scuttlebutt research method and long-term holding philosophy
Philip Fisher was the founding father of growth stock investing. His Common Stocks and Uncommon Profits introduced the famous 15-point stock selection criteria and the Scuttlebutt research method, emphasizing deep qualitative research to find excellent companies with sustained competitive advantages and holding them long-term. His multi-decade holding of Motorola is the best proof of his long-term holding philosophy. Buffett described his investment thinking as '85% Graham + 15% Fisher.'

Beliefs and mental models
- Scuttlebutt Research Is the Best Method for Finding Excellent Companies - By interviewing competitors, suppliers, customers, former employees, and industry experts, you can obtain a more accurate picture of a company's competitiveness than financial statements alone. This 'street intelligence' method reveals true company quality better than pure data analysis.
- Truly Excellent Companies Are Worth Holding Indefinitely - If you have chosen the right company, the best time to sell is 'almost never.' Frequent trading erodes compounding, while excellent companies' value grows continuously over time.
- Management Quality Is the Most Important Investment Variable - Even in a great industry, poor management will fail; even in a poor industry, excellent management can create value. Deep assessment of management integrity, capability, and long-term orientation is the core of stock selection.
- Scuttlebutt Intelligence Network - Build a panoramic understanding of a company's true competitiveness by interviewing competitors, suppliers, and customers.
- 15-Point Stock Selection Criteria - Systematically evaluate a company's growth potential and management quality across 15 qualitative dimensions; only high-scoring companies deserve investment.
- Three Principles for Selling - Only sell in three situations: the original buy judgment was wrong, company fundamentals have deteriorated, or a significantly better investment opportunity has emerged.
