These are 4 Business Judgment principles distilled from Julian Robertson'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. When a rule feels vague, open the full principle page and capture the driver you can verify (cash flows, leverage, incentives, competitive edge). This is educational, not investment advice—double-check primary sources and fit every rule to your time horizon, risk budget, and constraints.

Julian Hart Robertson Jr. He founded Tiger Management Corp.
Julian Robertson has 4 key principles on business judgment. The most important one is "Best vs. Worst Strategy" — Go long the best companies in an industry and short the worst.
Julian Robertson applies business judgment through several key principles including "Best vs. Worst Strategy" and "Deep Fundamental Research". These principles guide practical investment decisions and have been tested across decades of market cycles.
Julian Robertson's approach to business judgment is distinguished by a focus on long-term thinking and fundamental analysis. With 4 specific principles in this area, Julian Robertson provides a comprehensive framework that investors at any level can study and apply to improve their decision-making.
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.
Pick a cadence you can sustain (weekly or monthly) and review process signals first: whether you followed your checklist, respected your boundaries, and documented assumptions. Only then look at outcomes. The goal is fewer low-quality decisions, not perfect prediction.
