From the project README

透视盈余(含所有者收益/反EBITDA)

R — 原文 (Reading)

"We feel that the undistributed earnings of companies we hold in large amounts are fully as important to us as those we report." (1978) "References to EBITDA make us shudder — does management think the tooth fairy pays for capital expenditures?" (2000)

I — 方法论骨架

两个核心概念合并为一个skill:

透视盈余: 真实经济收益 = 报告利润 + 被投资公司未分配利润份额 - 假设税款

  • 会计只显示已收股息,但未分配利润也是你的(如果有控制权或长期持有)

所有者收益: 净利润 + 折旧摊销 - 维持性资本支出 ≠ EBITDA

  • 折旧不是"非现金费用"——它是预付资本的回收
  • EBITDA忽略了维持竞争地位所需的真实资本支出

A1 — 书中的应用

案例: Apple的透视盈余
  • 问题: 伯克希尔从Apple投资中获得多少?
  • 使用: 2021年伯克希尔享有的Apple收益=$56亿,但仅收股息=$7.85亿
  • 结果: 会计利润严重低估真实经济进展(差7倍)

A2 — 触发场景

  1. 分析一家利润高但资本支出也高的公司
  2. 评估一家控股/参股公司的真实盈利能力
  3. 有人用EBITDA估值——需要指出问题
  4. 理解为什么净利润和现金流差距很大
语言信号
  • "这家公司EBITDA很高"
  • "折旧不是现金成本"
  • "利润和现金流为什么差这么多?"
  • "未分配利润算不算我的?"
与相邻 skill 的区分
  • 与 economic-moat 的区别:护城河分析企业竞争力,透视盈余分析企业真实赚钱能力

E — 可执行步骤

  1. 计算所有者收益 = 净利润 + 折旧摊销 - 维持性资本支出

    • 完成标准:区分"维持性"vs"扩张性"资本支出
  2. 检查EBITDA陷阱

    • 完成标准:如果EBITDA >> 所有者收益,标注"盈利质量存疑"
    • 判停:如果EBITDA与自由现金流差距>50% → 发出警告
  3. 计算透视盈余(适用于有参股公司的情况)

    • 完成标准:报告利润 + 按持股比例的未分配利润 - 假设税款

B — 边界

  • 估计"维持性"vs"扩张性"资本支出需要判断——不同人可能得出不同结论
  • 透视盈余对短期投资者意义不大(未分配利润可能永远不实现)
  • 作者盲点:巴菲特有足够的控制权来确保未分配利润最终实现——散户没有
