An investing mindset that treats buying a share as owning part of a company, rather than betting on its price movements.

In plain words
What is it for?
Use it when someone is anxious about a stock rising or falling, asks whether to take profits or stop losses, or judges a stock by its price, PE ratio, or chart.
Why use it?
It helps separate changes in the market price from changes in the company’s business and cash flows. It is not intended for short-term trading or portfolio allocation.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

ownership-mindset scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

买股票就是买公司(企业所有者视角)

R -- 原文 (Reading)

我理解的投资归纳起来就是:买股票就是买公司,买公司就是买公司的未来现金流折现,句号!这就是我说的所谓的信仰的意思,或者说我是从骨子里相信,不会因为任何影响而动摇。

"买股票就是买公司"这句话会说的人非常多,但我几乎没见过真的骨子里理解并相信这句话的--我知道的人里面大概不超过5个。

-- 段永平, 第一章第1节「投资的信仰」


I -- 方法论骨架 (Interpretion)

  1. 公理: 买入一只股票 = 买入这家企业的一部分所有权,你不再是"炒股的人",而是"企业股东"。
  2. 核心心智模型: 把任何上市公司抽象为"只有一个股东的非上市公司"来思考,市场报价就变成了"别人今天愿意出多少钱买你的公司",而非"你的公司值多少钱"。
  3. 行为推论一 -- 不看盘: 如果你是公司唯一股东,没有人每天给你报价,你不会焦虑。股价下跌不改变公司的生意和现金流。
  4. 行为推论二 -- 全款买下思维: 买入前问自己,"如果我有足够多的钱把整个公司买下来,我愿意按这个价格买吗?"如果不愿意,买一股也不应该。
  5. 行为推论三 -- 上市与否无差别: 同样价钱下,买的公司是不是上市公司没有区别,上市只是提供了退出的便利。
  6. 检验标准: "骨子里理解"的人,在市场暴跌时不慌、在暴涨时不贪、从不因为股价变化而改变对公司的判断。做不到这一点,说明还没有真正理解。
  7. 与其他方法论的关系: 这是所有后续投资分析的元前提。不理解"买股票=买公司",能力圈、估值、好生意分析都建立在错误的地基上。

A1 -- 书中的应用 (Past Application)

案例 1: 网易 -- "买的是公司,上不上市无所谓"

  • 问题: 2002年网易股价跌破1美元,面临被摘牌的风险,市场无人问津。
  • 方法论的使用: 段永平每天买单有一半是他的。他的想法非常简单:买的是公司,上不上市无所谓。他从经营小霸王游戏机多年的经验中深刻理解游戏的巨大市场,所以他能判断网易的价值远高于当时的价格。
  • 结论: 确认网易的生意价值与是否上市无关,摘牌恐惧是市场的非理性定价。
  • 结果: 从约0.8美元买入,大部分拿到120-140美元才卖出,获得100倍以上回报。他说"当有人非要把金子按铜的价钱卖给你的时候,你是不需要勇气的,你只要确认那真的是金就行了"。

案例 2: 茅台 -- "假设茅台是一家非上市公司"

  • 问题: 2012年白酒塑化剂事件 + 禁酒令冲击,茅台股价暴跌至180元左右,市场恐慌。
  • 方法论的使用: 段永平委托朋友在美国送检茅台酒,确认塑化剂问题不是人为添加。然后问自己一个问题:"假设茅台是一家非上市公司,现在手里有200块钱,要么放银行里,要么放茅台上,看看10年后的差异。"从企业所有者视角,茅台的定价权、库存越久越值钱、预收款等特质不会因塑化剂事件改变。
  • 结论: 茅台的生意本质未变,股价下跌提供了更好的买入机会。从180元买到120元,越跌越买。
  • 结果: 持有茅台长期获得丰厚回报。段永平评价:"茅台这个生意和我们的消费电子比较起来,最大的差别可能就在库存上。我们这个行业的库存几乎就是垃圾,茅台几乎就是个宝。"

案例 3: 苹果 -- "用2000亿市值买个年赚200亿、5年后赚500亿的公司"

  • 问题: 2011年苹果市值约3000亿美元,市场对其增长持续性有分歧。
  • 方法论的使用: 段永平不做复杂的估值模型,而是以所有者视角做了一个简单判断:苹果手里有1000亿净现金,实际购买成本约2000亿,当前利润不到200亿/年,预计5年后利润大概率达到500亿/年。"如果有这个结论,买苹果不过是个简单算术题。"他能得出这个结论,靠的是在消费电子行业20多年的亲身体验(小霸王、步步高、OPPO的经历让他理解单品模式的威力)。
  • 结论: 苹果是以所有者视角一眼就能看出的好生意,买入理由与股价走势无关。
  • 结果: 持有苹果至今。他称苹果是"一直梦寐以求但似乎难以达到的生意模式"。

A2 -- 触发场景 (Future Trigger)

用户会在什么情境下需要这个 skill?

  1. 股价波动引发焦虑时: 用户持有的股票涨了或跌了,纠结是否卖出。此时需要把用户从"盯盘者"拉回"所有者"视角,问"如果这是非上市公司,你卖不卖?"
  2. 用错误锚点做决策时: 用户用PE、K线图、消息面、成交量等非本质因素作为买入/卖出的主要依据,需要引导其转向"公司本身值多少钱"的思考。
  3. 纠结"止盈/止损"时: 用户以买入成本为锚点决定是否卖出("已经赚了200%了要不要卖"或"被套了30%要不要割"),需要帮其理解成本价是沉没成本,与当前决策无关。
