Patient Liquidity Trading converts the absence of urgent information into an execution advantage. Instead of demanding an immediate transaction, the investor defines a broad set of acceptable holdings and waits for another participant who needs to trade quickly. That urgency creates a willingness to concede price, allowing the patient investor to buy nearer the bid or sell nearer the ask. Flexibility matters because rigid index changes and exact execution dates advertise demand and increase costs. The framework begins by avoiding unnecessary turnover, then treats each remaining trade as an opportunity to provide liquidity rather than consume it. Small savings per transaction can compound into meaningful performance improvements when applied systematically across large, long-held portfolios.
Origin
Extracted from Masters in Business. Booth developed the approach while Dimensional traded small-company stocks against informed and often urgent institutional investors.
Core principles
- 01Immediacy has a price
- 02Patient capital can supply liquidity to urgent traders
- 03Flexible execution avoids the costs of mechanical trading
- 04Low turnover is the first defense against trading costs
- 05A mutually beneficial trade can still reward the more patient party
How to run it
- 1
Minimize required turnover
Question whether each proposed trade is necessary for the portfolio's objective. Retaining an acceptable holding is usually cheaper than replacing it.
Pro tip Set broad eligibility rules rather than prescribing one exact portfolio at every moment.
Watch out Trading merely to make the portfolio cosmetically match a benchmark creates avoidable costs.
- 2
Create execution flexibility
Identify multiple acceptable securities, quantities, and execution windows. Flexibility prevents the portfolio from becoming a forced buyer or seller.
Pro tip Use portfolio-level characteristics to judge substitutions instead of fixating on one security.
Watch out Do not loosen eligibility so far that the intended risk exposure changes materially.
- 3
Find the urgent side
Look for counterparties whose information, mandates, or cash needs make immediacy valuable. Allow their urgency to bring the opportunity to you.
Pro tip Wide-spread and less-liquid markets often offer the clearest concessions.
Watch out Do not assume every apparent discount compensates for liquidity rather than deteriorating fundamentals.
- 4
Make the counterparty move first
Avoid signaling urgency and wait for the motivated participant to accept a favorable price. Supply liquidity only when the concession justifies the trade.
Pro tip Patience is strongest when the portfolio has no deadline and several substitutes.
Watch out Chasing a moving market turns the strategy from liquidity provision into liquidity consumption.
- 5
Capture the spread advantage
Execute near the favorable side of the bid-ask spread and compare the result with the price of immediate execution. Aggregate small improvements across the portfolio.
Pro tip Measure implementation shortfall, not just commissions.
Watch out A low commission does not compensate for a poor execution price.
- 6
Hold for the long term
Allow the execution saving to compound by avoiding rapid reversal of the position. Review whether turnover and realized costs remain consistent with the method.
Pro tip Track cost savings over long periods because individual trades may look immaterial.
Watch out Frequent subsequent trading can erase the original concession.
In the wild
Dimensional entered the small-cap market without claiming superior information about individual companies. Other institutions often believed they possessed short-lived insights and therefore wanted immediate execution. Dimensional waited for those sellers, supplied liquidity, and sought to purchase nearer the bid instead of paying the offer.
→ Patience turned wide spreads from a presumed disadvantage into a source of lower execution costs.
A conventional index fund must buy an addition and sell a deletion on specified dates. A flexible fund instead maintains acceptable exposure without joining the crowded trade immediately, waits for liquidity to improve, and uses substitute securities where its rules permit.
→ The portfolio preserves its intended exposure while reducing the price impact of mechanical trading.
Common mistakes
Advertising urgency
Revealing that a trade must happen immediately gives the counterparty leverage over the execution price.
Confusing activity with value
Frequent trading creates spreads, impact, and commissions without necessarily improving the portfolio.
Forcing exact index timing
Buying and selling on predetermined reconstitution dates concentrates demand and can make execution unnecessarily expensive.
Is it for you?
Best for
It is best for long-horizon funds that can substitute among acceptable securities and wait for liquidity.
Not ideal for
It is not ideal for strategies requiring immediate execution, exact index replication, or rapid response to new information.
From the transcript
“We approached the marketplace basically waiting for sellers wanting to come to us.”
“Absolutely, patients and flexibility, so uh, and coming to the marketplace, if you can get the other person to move first, then uh you can…”
“The best way to save on trading costs is not trade very often.”
