Six Exit Rules Based on Investment Criteria and Trading Signals
Summary
The document argues that investors should define conditions for leaving a position in advance and reassess holdings against their original investment rationale. It uses Warren Buffett and George Soros as examples: Buffett may sell when a company no longer meets his quality criteria, when capital has a better use, or when he recognizes an investment mistake. Soros is presented as exiting when a thesis plays out, when market evidence invalidates it, or when capital is at risk.
It then groups exits into six broad approaches: a changed fundamental case, a predicted event occurring, a target being reached, a technical system signal, a mechanical rule such as a stop, and acknowledgement of an error. These ideas span discretionary investing and systematic trading, but the examples are anecdotal rather than performance tests. The document offers no method for selecting or calibrating rules, and some examples are simplified; investors still need to account for time horizon, transaction costs, execution, and risk when applying them.
Key ideas
- An exit plan can be tied to the criteria that justified entering an investment.
- A position may be closed when its fundamental rationale changes or an expected event occurs.
- Price targets and technical signals provide distinct ways to define exit conditions.
- Mechanical stops can help enforce risk limits and protect accumulated gains.
- Recognizing an invalid thesis and accepting a loss is presented as a necessary exit discipline.
