做生意不做股票
R — 原文 (Reading)
"We think of ourselves as business analysts — not as market analysts, not as macroeconomic analysts, and not even as security analysts." (1987)
"Charlie and I are not stock-pickers; we are business-pickers." (2021)
I — 方法论骨架
买股票 = 买企业的一部分,应该用买整个企业相同的标准评估:
- 关注企业的经济特征(护城河/定价权/管理层),而非股价走势
- 关注长期现金流创造能力,而非季度盈利波动
- 不预测市场方向,只分析企业质量
- 持有期限以"年"计,以"天"计的是交易不是投资
A1 — 书中的应用
案例: Apple投资
- 问题: 如何在科技行业做价值投资?
- 使用: 把Apple当作企业而非股票——评估其生态系统锁定效应、用户忠诚度、现金流
- 结果: 5.55%股权,伯克希尔享有的Apple收益($56亿)远超收到的股息($7.85亿)
A2 — 触发场景
1. 用户问"这只股票会不会涨"——应转向"这个企业好不好" 2. 用户在看K线图或技术指标——应转向看财报和商业模式 3. 用户关注"市场情绪"而非"企业分析" 4. 用户纠结短期股价波动
语言信号
- "这只股票会涨吗?"
- "技术面怎么样?"
- "股价到支撑位了"
- "今天跌了X%,要不要卖?"
与相邻 skill 的区分
- 与
mr-market的区别:市场先生关注如何对待价格波动,做生意关注根本不看价格只看企业
E — 可执行步骤
1. 假设你要买整个公司——用评估私有企业相同的标准
- 完成标准:写出一页"如果这家公司是非上市的,你愿意出多少钱买"
2. 评估三个核心维度
- 经济特征(护城河宽度)
- 管理层质量(诚信+能力)
- 价格与价值的关系
- 完成标准:每个维度有具体证据支持
3. 忽略所有市场噪音(股价走势/分析师评级/市场情绪)
- 完成标准:决策文档中不包含任何价格走势相关的内容
B — 边界
- 需要能力圈——不是所有企业你都能分析
- 非上市企业没有流动性,不能简单类比
- 作者盲点:巴菲特可以影响企业决策(控股/董事席位),散户不能
