INVESTMENT MASTERS

Learn from Legendary Investment Masters

Master pages are decision lenses: they turn a legendary investor’s philosophy into a checklist you can run on any stock. Start by choosing one master whose style fits your question (valuation, quality, cycles, or risk), then rate your evidence and write 1–2 disconfirming signals. Use the Principles tab to explore the full ruleset, and Quotes to see how ideas translate into simple, testable statements. This is educational—not a trade signal—so don’t copy positions without checking your own numbers, constraints, and time horizon.

How to use a master lens

Master pages are thinking tools, not trade signals. Use them to borrow a process: build a checklist, define what would change your mind, and keep your decision record consistent across cycles.

Decision checklist (5 minutes)

  1. Pick one master whose style matches your situation (valuation, quality, cycles, or risk).
  2. Write your thesis in one sentence and list 2–3 disconfirming signals.
  3. Run the master’s core dimensions and rate evidence quality (strong/weak/missing).
  4. Define a guardrail: position size, downside risk, and a review date.
  5. If evidence is missing, create a research task—don’t “fill the gap” with conviction.

When not to use it

  • When you want a price target or a guaranteed buy/sell conclusion.
  • When you are copy-trading a quote without checking your own constraints and numbers.
  • When your plan depends on short-term news timing rather than a repeatable process.

⚠️ Educational only—always do your own research and decide based on your own risk, time horizon, and constraints.

FAQ

Which master should I start with?

Start with the style that matches your current question. If you’re sizing or valuing a long-term position, Buffett/Graham-style checklists tend to help. If your stress is about cycles and risk, Marks/Dalio-style framing can be useful. The best first master is the one whose checklist you will actually execute.

Should I copy a master’s positions or portfolio?

No. Copying positions skips the part that matters: your constraints, entry price, sizing, downside tolerance, and time horizon. Use a master lens to copy the reasoning process (questions to ask), not the conclusion (what to buy).

How do I avoid quote-mining or “name-swapping” analysis?

Use quotes as pointers, not proof. Always translate a quote into a checklist item you can verify (numbers, evidence, triggers). If you can’t write a concrete check, it’s probably inspiration—not a decision rule.

What’s the fastest path from a master page to action?

Pick one master, run the 5-minute checklist, then open one Scenario to rehearse your response under stress. Finally, write one guardrail in your Journal (position size, review date, and what would change your mind).
