+
+# Valuation Review
+
+Use this skill when the task requires determining whether a stock is cheap, expensive, or fairly priced.
+
+## Workflow
+
+1. Use more than one valuation method when possible.
+2. Compare intrinsic value estimates with current market pricing.
+3. Explain the key assumptions behind the valuation view.
+4. State the margin of safety and what could compress or expand it.
+
+## Guardrails
+
+- Treat valuation as a range, not a single precise number.
+- Call out assumption sensitivity.
+- Avoid high-confidence calls when inputs are sparse or unstable.
