-# Valuation Review
+# 估值分析
 
-Use this skill when the task requires determining whether a stock is cheap, expensive, or fairly priced.
+当任务需要判断一只股票是低估、高估还是定价合理时，使用这个技能。
 
-## Workflow
+## 工作流程
 
-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.
+1. 条件允许时，使用不止一种估值方法。
+2. 对比内在价值估计与当前市场价格。
+3. 解释估值判断背后的关键假设。
+4. 明确安全边际，以及哪些因素会压缩或扩大它。
 
-## Guardrails
+## 约束
 
-- Treat valuation as a range, not a single precise number.
-- Call out assumption sensitivity.
-- Avoid high-confidence calls when inputs are sparse or unstable.
+- 将估值视为区间，而不是一个精确点值。
+- 明确说明假设敏感性。
+- 当输入稀疏或不稳定时，避免给出高置信度判断。
