  3. Hybrid policies work best with role separation

Visual Playbook

Principles-based investing workflow

Step 1

Stop losses protect against market-speed risk

When volatility and liquidity matter more than long-form analysis, stop rules can prevent small mistakes from becoming catastrophic losses.

Portfolio execution and review process

Step 2

Thesis exits protect against reasoning failure

Long-term investors need explicit invalidation logic because some broken theses do not show up cleanly in one price level.

Step 3

Hybrid policies work best with role separation

Use price-based controls for tactical risk and thesis rules for strategic exits, with no overlap ambiguity.

FAQ

Should long-term investors use stop losses?

Some do, but only if the stop policy is consistent with the holding period and thesis structure.

What is the biggest mistake with stop losses?

Applying them mechanically to long-horizon ideas without defining what happens after a stop is triggered.

Can both methods coexist?

Yes. The key is assigning each method a clear role in the decision stack.
