These are 3 Investment Philosophy principles distilled from Philip Fisher's writing and public remarks. Use them as a decision checkpoint: translate each rule into a yes/no test, write what evidence would change your mind, and set a review date before you act.

Treat each principle as a hypothesis. Write the evidence you would need, collect it from primary sources when possible (filings, letters, transcripts), and note what would invalidate the conclusion. If you can’t define inputs and triggers, you’re not applying the rule—you’re quoting it.
