This decision rule starts by identifying the monetary-liquidity regime before drawing conclusions from valuation. When the Federal Reserve is expanding liquidity, easing rates, or validating market expectations, risky assets can remain elevated even when fundamentals appear stretched. Investors therefore distinguish what they believe policy should be from what policymakers are actually doing. The supportive stance is not treated as an unconditional buy signal: tightening, balance-sheet contraction, credit-market stress, or a synchronized global recession can end the regime. The method combines policy direction, balance-sheet movement, market-implied expectations, credit conditions, and international cycle data. Its output is a portfolio risk posture—constructive, cautious, or defensive—rather than a precise price target. Risk controls remain essential because liquidity can delay valuation consequences without eliminating them.
Origin
Extracted from Masters in Business after Danielle DiMartino Booth described fighting Fed policy as the largest mistake of her career and explained her revised investment rule.
Core principles
- 01Liquidity can dominate valuation for extended periods
- 02Accommodative policy supports risky assets until the regime changes
- 03Global recession can overwhelm domestic monetary support
- 04Portfolio positioning should respond to policy direction, not personal approval of it
How to run it
- 1
Identify policy direction
Classify current policy as accommodative, neutral, or restrictive using rates, guidance, and balance-sheet operations. Focus on observable actions rather than rhetoric alone.
Pro tip Track changes in the direction and pace of policy, not just its absolute level.
Watch out A low policy rate can still be restrictive if liquidity is being withdrawn rapidly.
- 2
Compare policy with expectations
Review market-implied paths for rate changes and whether the Fed tends to validate them. Large gaps between expectations and official guidance can create regime-transition risk.
Pro tip Monitor both policy meetings and the expectations embedded in rates markets.
Watch out Market expectations can change abruptly and are not guarantees of Fed action.
- 3
Test global confirmation
Examine yield curves, industrial activity, employment, and recession conditions in major trading partners. Identify whether global weakness is broad enough to overpower domestic liquidity support.
Pro tip Distinguish temporary shocks from synchronized, persistent contraction.
Watch out Calling every foreign slowdown a global recession will produce excessive defensiveness.
- 4
Choose the risk posture
Remain constructive while accommodation and cycle evidence support risky assets, become cautious as signals conflict, and turn defensive when liquidity reverses or synchronized recession takes hold.
Pro tip Translate each regime into predetermined exposure ranges.
Watch out Do not interpret constructive positioning as a reason to use unlimited leverage.
- 5
Rebalance boldly but diversely
Express the regime through deliberate allocations while retaining assets that address uncertainty and tail risk. Review credit quality rather than trusting labels alone.
Pro tip Use position limits and rebalance thresholds to prevent conviction from becoming concentration.
Watch out A liquidity thesis does not protect weak issuers from default.
In the wild
After leaving the Federal Reserve, DiMartino Booth believed risky assets were overvalued but recognized that continued money creation could keep prices elevated. She later described fighting that liquidity as the biggest mistake of her career and adopted a more constructive stance while accommodation persisted.
→ The revised rule separated criticism of policy from the investment implications of policy.
An investor observes an expanding central-bank balance sheet but also sees broad recessions across major economies, contracting trade, and rapidly deteriorating credit. The framework shifts the portfolio from constructive to cautious because global contraction may overwhelm the liquidity support.
→ Exposure is reduced without assuming either liquidity or recession indicators are infallible.
Common mistakes
Trading the policy you want
Moral or economic disagreement with central-bank policy does not determine near-term asset prices. Portfolios must respond to the regime that exists.
Treating liquidity as invincible
A severe synchronized recession or policy reversal can overwhelm support and expose weak fundamentals quickly.
Ignoring credit quality
Broad monetary accommodation does not make every corporate borrower solvent or every investment-grade label reliable.
Is it for you?
Best for
It is best for macro-aware investors allocating across equities, bonds, gold, and other risk assets.
Not ideal for
It is not ideal for short-horizon security selection or as permission to ignore solvency, concentration, and downside risk.

“as long as the as long as the FED is printing, they cannot be fought.”
“I knew in my guts that as long as they printed enough that they were going to hold up risky asset prices, it didn't matter…”
“I've learned to not fight the FED.”
