  1. Observe before you speculate

    Begin with a record, not a prediction.

  2. A quotation is not an execution

    The market you can observe is not always the market you can trade.

  3. Paper profits are not a complete test

    Money at risk changes both execution and behaviour.

  4. Who controls the rules?

    Counterparty and venue risks belong in your analysis.

  5. Do not force a pattern

    A familiar chart can conceal unfamiliar conditions.

  6. Treat intuition as a question

    A memorable hunch is not a complete record.

  7. Add exposure with a reason

    A better price and a better decision are different things.

  8. Patience needs an investment thesis

    Holding on and refusing to reconsider can look alike.

  9. A rally does not settle the liquidity question

    Price strength and financial resilience are separate observations.

  10. Make mistakes specific

    A useful review changes a process, not just a mood.

  11. Size changes the exit

    A small position’s experience may not scale.

  12. Expertise is not permission to stop thinking

    Separate respect for a person from evidence for a position.

  13. Protect the person making the decision

    Stress changes the quality of judgment.

  14. The market does not owe you an opportunity

    Needing a return is not evidence that one is available.

  15. Prepare for discontinuity

    Not every loss comes from a gradually changing price.

  16. Ask why the tip is reaching you

    Attention can serve the seller’s objective.

  17. Explain the signal, not the legend

    A dramatic story can hide an ordinary decision process.

  18. Understand a squeeze without assuming one

    Short selling creates obligations as well as opinions.

  19. Markets have rules—and the rules evolve

    Historical description is not modern permission.

  20. A story is not a market-impact model

    Large transactions require analysis beyond folklore.

  21. Activity does not establish value

    A market can become lively without improving the business.

  22. Read through financial packaging

    New certificates do not automatically create new value.

  23. Protection is more than a price forecast

    Governance and market integrity belong in the investment process.

  24. Look beyond today’s earnings

    An investment argument needs a future and an incentive check.
