Watchlist Design: Smaller Lists Win

A giant watchlist feels productive. In practice, it weakens signal quality. If you cannot explain each business quickly, alerts will not translate into good actions.

Why Smaller Lists Work

A focused list means:

• You know the business model and balance sheet.
• Alerts have context.
• You can act from a predefined plan.

A Practical Starting Rule

Start with 10 to 20 names you would own for years. Then use the 200-week signal to decide when to run deeper review.

This fits the core Munger-style logic: quality first, timing second.

Expand Slowly

Only add names when your current list is fully documented:

• Thesis in one sentence
• Risk flags you monitor
• Entry and sizing rules

The 200-week line is most useful when the watchlist itself is high quality.

Signals are informational only and not financial advice.
