Stop-Loss Discipline

所有净值曲线背后都是人，正态分布的普通人 adds the fixed-income-plus stop-profit and stop-loss version. In the source, exits are judged against risk budget and client holdability: a stop may lower the eventual return if the asset rebounds, but it can keep the product inside the drawdown range that lets clients stay.

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 FOMO version. For positions bought from tips, unfamiliarity, or late-cycle fear of missing out, 大卫翁 says a 20%-from-high exit rule remains a usable discipline, while a looser 30% threshold may be debated only if the investor still writes and follows a rule.

157.如何带走牛市的胜利果实？ adds a stop-profit variant. For assets already judged bubbly, 大卫翁 treats a large fall from the high as a reason to leave and keep the gains, while warning that the rule is not a universal interpretation of every drawdown and that immediate reentry can undo the whole purpose.

Stop-loss discipline is the rule-based loss-control practice emphasized in EP76 穿越1940：我与股票大作手利弗莫尔的最后对话. The source treats stop-losses as a way to protect capital and psychological capacity when the market has not confirmed the trader’s thesis.

E153.股神的牌局：复利公式 + 凯利公式 adds a Kelly Criterion and Position Sizing angle: a trade is a probe, and if the market does not confirm the expected path, exiting protects the repeated-game ability to keep playing. The episode also argues that larger or added positions require stricter exits because the same mistake now has more capital behind it.

vol.104.普通人港股完全生存指南 | 串台三点下班 adds the Hong Kong small-cap version. 浩哥 frames fast cutting as essential because Hong Kong Liquidity Exit Risk can make a late exit much worse than the quoted price move suggests.

Key Claims

  • A stop-loss is not only a price level; the episode also mentions time or behavior stops when a position fails to show expected strength after entry.
  • The fixed-income-plus source adds that take-profit can be as important as stop-loss because realized gains become budget for future risk-taking.
  • Technical stops should be tied to meaningful trend or key-point failure rather than moved repeatedly because the trader hopes to be right.
  • Trailing stops let a profitable trend run while still protecting much of the prior gain when trend evidence deteriorates.
  • Stop-loss discipline is the practical opposite of Averaging Down in an active trade.
  • The source warns that “再看一天” can become the emotional loophole through which a small loss becomes a career-ending loss.
  • E153 adds that no-floating-profit trades should be reviewed quickly, while profitable trades can be held only while the trend or thesis remains intact.
  • Stop-loss rules become more important after add-on buying because the correlated exposure has increased.
  • In thin Hong Kong stocks, stop-loss rules also protect exit liquidity: waiting for certainty can mean competing with other sellers in a market with little depth.
  • Episode 157 adds that trailing exits can function as stop-profit rules when the aim is preserving bull-market gains rather than only cutting initial losses.
  • Episode 171 adds that late-cycle FOMO positions need faster exits than long-term value positions because the entry reason is weaker and usually less researched.
