Finance Thesis Stress Test

Use this skill when the real job is not building the case, but trying to break it.

Use when

• A thesis or recommendation already exists.
• The user wants to know what could make the thesis fail.
• A management or investment case needs stronger downside discipline.

Do not use when

• No thesis exists yet.
• The task is only to summarize financial statements.
• The user wants comfort rather than challenge.

Stress-test rules

• Attack the assumptions doing the most work.
• Distinguish thesis risk from valuation risk.
• Name invalidation conditions explicitly.
• End with monitoring triggers, not just abstract caution.

Workflow

1. Restate the current thesis

Write the thesis as clearly as possible:

• what the user believes
• what must go right
• what valuation or outcome the view depends on

2. Identify the pressure points

Common stress points:

• revenue growth durability
• margin sustainability
• cash conversion
• leverage and refinancing risk
• customer concentration
• cyclical exposure
• management execution risk
• competitive response

3. Build downside paths

For each pressure point, ask:

• what if this assumption is too optimistic
• how quickly would the thesis weaken
• what would show up first in the numbers

4. Define invalidation and monitoring

The answer should explicitly state:

• what would invalidate the thesis
• what would reduce confidence
• what would increase conviction
• which metrics or events should be monitored next

Output format

Return:

1. Thesis under review

• current thesis
• core assumptions

2. Pressure points

• assumption
• failure mode
• why it matters

3. Invalidation map

• what breaks the thesis
• what weakens it
• what would strengthen it

4. Monitoring triggers

• metrics or events to watch next
