Scuttlebutt research, 15 points, growth-at-quality (Common Stocks and Uncommon Profits)

Philip Fisher founded Fisher & Co., an investment counsel firm, and managed it for decades with a concentrated focus on high-quality growth businesses. His 15-point framework for evaluating companies emphasised management integrity, R&D depth, and profit margins over pure balance-sheet metrics. His scuttlebutt method—systematically interviewing competitors, suppliers, and customers—became a foundational practice in fundamental equity research.
