The Post-Error Risk Reset treats being wrong as both a financial event and a decision-quality hazard. Zulauf observes that an investor under pressure becomes more likely to compound the original error. The first task is therefore to stop the immediate damage and create psychological distance rather than force a quick recovery. The investor then returns to the evidence, rebuilds the analysis independently of the failed thesis, and defines a new price range, target, and invalidation condition. Re-entry occurs only when those conditions arrive. Finally, the episode becomes feedback for stronger risk procedures. The mechanism converts a loss from an emotional demand to win the money back into a controlled research and execution process.
Origin
Extracted from Masters in Business through Felix Zulauf's accounts of missing Japan's late-1980s rise and suffering a major loss in silver before rebuilding his analysis.
Core principles
- 01Being wrong increases the risk of further mistakes
- 02Emotional distress is a signal to stop improvising
- 03Fresh analysis should replace attachment to the original position
- 04A recovery trade needs an independent thesis and target
- 05Position size must reflect both evidence and psychological readiness
How to run it
- 1
Stop the damage
Recognize when price action has invalidated the expected move and reduce or close the position. Do not keep changing the forecast merely to justify remaining invested.
Pro tip Use predefined invalidation levels so the decision does not depend entirely on emotion.
Watch out Waiting until distress becomes unbearable can turn a manageable mistake into a severe loss.
- 2
Create psychological distance
Pause active decision-making long enough to weaken the urge to recover the loss immediately. Reduce exposure to emotionally triggering price monitoring if necessary.
Pro tip Write down what happened before looking for the next trade.
Watch out A pause should enable analysis, not become permanent avoidance.
- 3
Return to first-principles analysis
Reassess the market without assuming the original direction or timing remains valid. Determine the new destination, entry conditions, and evidence required.
Pro tip Ask what position you would choose if you had never made the original trade.
Watch out Do not disguise a revenge trade as updated research.

Plan the re-entry
Set a specific entry range, expected path, target, and invalidation point before committing capital. Size the position according to both the evidence and the remaining uncertainty.
Pro tip Wait for the market to reach the planned range rather than chasing it.
Watch out Increasing size after a loss magnifies both financial and psychological risk.
- 5
Upgrade the risk process
Review why the mistake persisted and change the procedures governing exposure, monitoring, or exits. Apply the lesson across similar positions rather than only to the original market.
Pro tip Convert the lesson into a written rule that can be checked before future trades.
Watch out A profitable recovery does not erase flaws in the original risk process.
In the wild
After silver fell from fifty to thirty-five, Zulauf bought expecting a rebound to forty-five. It continued falling, and he exited around eighteen with a roughly fifty percent loss. He stopped watching, redid the analysis, concluded silver could reach ten, and waited. Around that level he bought a much larger position with a forecast that it could double; the subsequent rally allowed him to recover profitably.
→ A damaging trade became a planned re-entry based on fresh analysis rather than an immediate attempt to win back the loss.
Zulauf remained underweight as Japanese equities rose after the 1987 crash. Although he was not short, the relative-performance pain affected him psychologically. He returned to his analysis, later positioned for the 1990 decline, and used the experience to strengthen his risk-management procedures.
→ The missed upside became a lesson in managing the decision risks created by sustained underperformance.
Common mistakes
Trying to win it back immediately
The desire to erase a loss encourages impulsive entries and oversized positions before a valid new thesis exists.
Keeping the failed thesis intact
Changing only the price target while preserving the original assumptions prevents genuine reassessment.
Mistaking recovery for validation
A later profitable trade does not prove the earlier process was sound. The original failure still needs to improve future risk controls.
Is it for you?
Best for
It is best for discretionary investors and traders recovering from a loss, missed move, or invalidated thesis.
Not ideal for
It is not ideal for investors who lack predefined risk limits or cannot tolerate the possibility of another loss.
From the transcript
“when you are wrong in the market, you increase the risk of making wrong decisions and mistakes.”
“And then I went back to the drawing board and doing my analysis,”
“it really helped me to tighten my risk management procedures”
