Investment Cooldown Discipline

176.纽约一年：一个悲观主义者的活法｜725沙龙实录 adds the finance-app-friction version. 大卫翁 argues that financial technology can make investing action too easy, so deliberate waiting, written reasoning, and learning from market history become useful artificial friction against loss aversion, premature profit-taking, and narrative chasing.

171.为什么牛市后期更容易亏钱？｜半年度投资账复盘 adds the late-bull-market review version. 大卫翁 says he tries not to trade before finishing his monthly investment-account review, using the bookkeeping rhythm to keep volatile late-cycle information from becoming immediate account action.

Investment cooldown discipline is the vol.105 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.

166.普通人能从机构投资者身上学到什么？｜串台投资ABC adds a simpler stock-pool analogy: when an ordinary investor wants to buy a new stock, they can force themselves to wait seven days, and when they want a very large weight, they should write the reason as if reporting to an investment committee.

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.
• Episode 166 adds that cooldown can imitate part of institutional stock-pool and committee friction without requiring a real institution.
• Episode 171 adds that a fixed review cadence can be especially useful when late-cycle social media, account-checking, and investor groups increase trading impulse.
