These are 3 Selling & Review principles distilled from Ray Dalio'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.
"Don't worry about looking good — worry about achieving your goal. If you're wrong, acknowledge it quickly and move on. The cost of being wrong increases with time."
Cut losses quickly by acknowledging mistakes early.

Ray Dalio has 3 key principles on selling & review. The most important one is "Acknowledge Mistakes Fast" — Don't worry about looking good — worry about achieving your goal.
Ray Dalio applies selling & review through several key principles including "Acknowledge Mistakes Fast" and "Review Through Principles". These principles guide practical investment decisions and have been tested across decades of market cycles.
Ray Dalio's approach to selling & review is distinguished by a focus on long-term thinking and fundamental analysis. With 3 specific principles in this area, Ray Dalio 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.
