Investment Cooldown Discipline

Investment cooldown discipline is the vol.105 [[QizhulouYanBinke|起朱楼宴宾客]] rule for slowing down large investment decisions before emotion turns into turnover. The host’s personal rule is proportional: a decision involving 1% of liquid assets requires a one-day cooling-off period, 2% requires two days, and monthly investment actions are capped at 5% of liquid assets.

The point is not that every investor should copy those exact numbers. The concept is that process friction can be a risk-control tool when short news cycles, social-media urgency, and market narratives make the investor want to change a portfolio too often.

Key Claims

• Cooldown rules turn emotional certainty into time for review.
• The waiting period should rise with position size because larger decisions can do more portfolio damage.
• Turnover caps help prevent a portfolio from being rebuilt several times a year in response to transient headlines.
• The rule complements Position Sizing because size should determine how much evidence and patience a decision needs.
• The rule also complements Investment Decision Logging: the cooling period is more useful when the thesis and invalidation condition are written down.
• Excessive liquidity can make action too easy, so cooldown discipline can be a behavioral substitute for hard lockups.

Connections

• Investment Risk Management — broader risk-control system.
• Position Sizing — capital-size input for required patience.
• Behavioral Investing Biases — impulse, herding, and confirmation-bias risks the rule slows down.
• Investment Decision Logging — written process that can be paired with the waiting period.
• Investment Liquidity Tradeoff — behavioral reason liquidity sometimes needs self-imposed constraints.
• Portfolio Suitability — the rule helps keep decisions aligned with the investor’s actual goals and tolerance.
