Exit Strategy

The best time to plan your way out is before you go in.


An Exit Strategy is a plan for leaving an investment, market or commitment: the conditions that trigger it, how you'll do it, and how you'll protect what you've built. At Gallipoli, a carefully planned withdrawal got over 100,000 troops out with very few casualties.

Use it before you start anything uncertain: write your stop and continue criteria, set money rules while calm, and build review points into commitments. Revisit the plan as facts change.
