John Neff vs Peter Lynch : Philosophie d'Investissement Comparée
Comparing 49 vs 71 investment principles across 16 common topics
Use this page to compare John Neff and Peter Lynch by decision process, not by performance claims. Start with each investor’s style summary, then scan the 16 shared topics to see where their principles overlap. If you are new, begin with the common topics; if you have a specific problem, jump to the topic table and open the related rule pages. Next, use the unique-topic lists to choose a framework that fits your current question (risk control, valuation discipline, thesis review, or behavior). Open 2–3 linked principle pages and write one “what would change my mind?” trigger in your journal. Educational only.
Decision Checklist (How to Choose)
Name the decision and time horizon (buy/hold/sell review, sizing, or thesis update).
Read both style summaries first; note what each emphasizes and what they explicitly avoid.
Pick 1–2 topics that matter to your decision and compare principle counts side-by-side.
Use the common topics as your baseline checklist, then add one unique topic as a differentiator.
Write 1–3 invalidation triggers (what evidence would change your mind) and set a review date.
If you disagree with a principle, write why—and what evidence would change that view.
Misuse and Risk Warnings
Do not treat principle counts as skill, performance, or expected returns—they only describe coverage.
Avoid cherry-picking the master you already prefer. Force yourself to read the strongest counter-framework.
Quotes, bios, and labels are context; your final decision still requires your own research and risk limits.
