Philip Fisher Growth Stock Investing Framework

This skill encodes the complete methodology from Philip Fisher's Common Stocks and Uncommon Profits (1958, revised 1960). Fisher is one of history's greatest investors — Warren Buffett credits him as a major influence alongside Benjamin Graham.

Core Philosophy: Buy exceptional companies at reasonable prices and hold them almost forever. The goal is gains of several hundred percent over years, not small short-term profits. Most great gains come from a very small number of outstanding companies — finding them requires deep research, not superficial statistics.
