Bear Case

A bear case is the downside version of a stock thesis. It explains what could go wrong, which risks matter most, and how those risks could pressure earnings, valuation, liquidity, or investor confidence.

Why it matters

Bear cases reduce blind spots. They force you to ask whether a thesis depends on perfect execution, generous valuation, low interest rates, stable demand, or assumptions that have not been tested in a tougher environment.

Common bear-case drivers

• Revenue growth slows faster than expected.
• Margins compress because input costs rise or pricing power fades.
• Debt, dilution, or refinancing risk becomes more important.
• A major customer, supplier, regulator, or competitor changes the setup.
• The stock's valuation multiple falls even if the company keeps growing.

How to use it

A bear case should inform risk/reward, position sizing, and exit rules. It is not a prediction that the worst outcome will happen. It is a map of what evidence would make the original thesis weaker.
