The Precommitted Volatility Playbook converts future market moves into decisions before emotions run high. While conditions are calm, the team chooses measurable thresholds for adding exposure during declines, specifies how much risk to add at each level, and defines recovery levels at which it will lighten exposure. The staged structure avoids requiring a perfect call on the market bottom and creates a symmetrical plan for both corrections and rebounds. When volatility arrives, the team checks that the playbook's assumptions and risk constraints still hold, then executes rather than improvising under stress. Its mechanism is behavioral as much as financial: advance commitments reduce paralysis, fear, overreaction, and stakeholder bias while making strategy easier and less stressful to implement.

Core principles
- 01Make difficult decisions before stress impairs judgment
- 02Translate market moves into explicit action thresholds
- 03Scale exposure progressively rather than betting on one turning point
- 04Prepare rules for both selloffs and recoveries
- 05Use precommitment to constrain emotion and bias
How to run it
- 1
Select the trigger measure
Choose the index, spread, valuation measure, or portfolio drawdown that will trigger action. Define it precisely enough that everyone observes the same signal.
Pro tip Use measures directly connected to the exposure being changed.
Watch out A vague trigger such as 'markets look cheap' restores discretion at the worst moment.
- 2
Set downside levels
Define a sequence of decline thresholds at which the portfolio will add risk. Space the levels to reflect plausible volatility and available capital.
Pro tip Use several increments rather than one all-or-nothing entry.
Watch out Do not allocate so much at the first threshold that nothing remains for a deeper correction.
- 3
Size every action
Specify exactly how much exposure will be added at each downside level. Verify the cumulative position against liquidity and risk limits.
Pro tip Express sizes in both portfolio percentage and capital terms.
Watch out Triggers without predetermined sizing still leave the hardest decision unresolved.
- 4
Plan the recovery
Define levels at which a rebound has gone far enough to justify reducing the added exposure. State how quickly the portfolio will return toward its strategic allocation.
Pro tip Make recovery rules symmetrical with the downside ladder where appropriate.
Watch out Without an exit rule, a tactical addition can silently become a permanent position.
- 5
Validate and execute
Approve the playbook while calm, then execute it during volatility unless new evidence invalidates its core assumptions. Record any override and its rationale.
Pro tip Review playbooks after each episode to improve thresholds and governance.
Watch out Frequent discretionary overrides destroy the precommitment benefit.
In the wild
A portfolio enters the year cautiously positioned. Before volatility begins, its committee authorizes incremental equity purchases after successive market declines and specifies smaller reductions after a strong recovery. When a policy shock causes a sharp selloff, the team checks liquidity and executes the first scheduled purchase instead of debating whether the headlines feel frightening.
→ The team adds risk systematically without needing to predict the exact bottom.
A credit investor creates spread thresholds for adding high-quality corporate bonds and later trimming them if spreads rapidly normalize. Each step has a fixed allocation and a maximum cumulative risk budget. During a sudden widening, the rules direct measured purchases while preventing an uncontrolled reach for yield.
→ Volatility becomes a planned rebalancing opportunity rather than an emotional decision point.
Common mistakes
Writing the plan during the selloff
Stress and ambiguous information are already impairing judgment by then. Build and approve the rules in advance.
Trying to identify one perfect bottom
A single entry threshold makes success depend on precision. Use a ladder of progressively sized actions.
Preparing buys without exits
A complete playbook must explain when recovered markets warrant lightening the added risk.
Is it for you?
Best for
This is best for disciplined investors who can define risk limits and rebalance across volatile market cycles.
Not ideal for
It is not ideal for portfolios facing forced liquidation or structural changes that invalidate their original assumptions.
From the transcript
“we think ahead of risk events.”
“if the market moves up or down at certain levels, these are the levels at which we'll add risk.”
“those playbooks have taken the emotion and the bias out of the decisions”
