Cyclicals

周期性业务分析

Take a cyclical business and locate it in its cycle, normalize its earnings, run the P/E inversion, read the top/bottom tells, and end in a disposition framed as thinking. Cyclicals break naive P/E thinking - the job is to value them on mid-cycle (normalized) earnings and judge where in the cycle they sit, never to trust spot earnings or a spot multiple. This is a thinking tool, not financial advice; never tell the user to buy or sell, surface the reasoning and a disposition.
The playbook (what counts as cyclical, the tells, the normalized-earnings method, Lynch's framing) lives in 
playbook.md
 next to this file. Read it at the start of every run; it is a living list the user grows.
When to use this: 
/cyclicals
, 
/munger
, and 
/investment-checklist
are independent tools. Reach for this one when the business is cyclical and the cycle itself is the crux.
针对某一周期性业务，确定其在周期中的位置，对其收益进行标准化处理，开展市盈率反转分析，识别顶部/底部信号，最终以思考框架给出倾向性判断。周期性业务会打破朴素的市盈率思维——我们需基于周期中期（标准化）收益对其估值，并判断其所处的周期阶段，绝不能轻信即时收益或即时估值倍数。这是一款思考工具，而非财务建议；绝不向用户给出买入或卖出指令，仅展示推理过程和倾向性判断。
操作手册（包括周期性业务的定义、信号识别方法、收益标准化方法、林奇框架）存放在本文件旁的**
playbook.md
**中。每次运行前需阅读该手册；它是一份由用户不断完善的动态清单。
适用场景： 
/cyclicals
、
/munger
和
/investment-checklist
是独立工具。当业务具有周期性且周期本身是核心关注点时，可使用本工具。

Workflow

工作流程

1. Confirm it is actually a cyclical

1. 确认业务确实具有周期性

Apply the earnings-line test: a growth business's earnings slope steadily up; a cyclical's wobble up and down. Does it sell expensive or deferrable goods (postponable when cash is short), as opposed to staples? If it is not cyclical, say so plainly and point the user to 
/munger
or 
/investment-checklist
instead.
应用收益曲线测试：成长型业务的收益呈稳定上升趋势；周期性业务的收益则上下波动。该业务是否销售高价或可延迟购买的商品（资金短缺时可推迟购买），而非必需品？若不具备周期性，需明确告知用户，并引导其使用
/munger
或
/investment-checklist
工具。

2. Locate the cycle position - with evidence

2. 确定周期位置——附证据

Where in the cycle is it, and what is the evidence: demand trend, capacity utilization, order book/backlog, inventories, pricing power, margins vs the cycle's own history, capex, balance sheet/dividend, and sentiment. Lynch's buy zone: economy weakest, earnings lowest, sentiment bleakest.
判断其处于周期的哪个阶段，并提供证据：需求趋势、产能利用率、订单/未交付订单量、库存、定价权、利润率与自身周期历史对比情况、资本支出、资产负债表/股息以及市场情绪。林奇买入区间：经济最疲软、收益最低迷、市场情绪最悲观之时。

3. Normalize the earnings

3. 收益标准化处理

Estimate mid-cycle EPS across a full peak-to-trough cycle (or a normal margin on normal volume). State whether current earnings sit near peak or trough. The airline lesson: "$15 a share one year, minus $15 the next - a $15-a-share operation no matter what." Never extrapolate peak or trough earnings as permanent.
估算完整峰值到谷值周期内的周期中期EPS（或基于正常销量的正常利润率）。说明当前收益是接近峰值还是谷值。航空业的经验：“某一年每股收益15美元，下一年每股亏损15美元——但无论如何，这是一项每股收益15美元的业务。”绝不能将峰值或谷值收益推断为永久性收益。

4. Run the P/E inversion (mandatory - the central trap)

4. 开展市盈率反转分析（必做——核心陷阱）

A low P/E on peak earnings is expensive and late (the multiple is low because the market knows earnings will fall) - the classic value trap. A high or N/A P/E on trough earnings can be cheap and early. Value on the normalized number from step 3, not on the reported one.
峰值收益对应低市盈率，实则估值过高且已处于周期后期（倍数低是因为市场知晓收益将下滑）——这是典型的价值陷阱。谷值收益对应高市盈率或无市盈率，实则估值较低且处于周期早期。需基于步骤3得出的标准化数值进行估值，而非基于报告的即时数值。

5. Read the tells

5. 识别信号

From 
playbook.md
, name which top tells and which bottom tells are firing, each tied to a concrete fact about this business.
从
playbook.md
中找出当前触发的顶部信号和底部信号，每个信号需与该业务的具体事实相关联。

6. Disposition

6. 倾向性判断

Synthesize: where in the cycle, the normalized earnings power, the dominant tells, what would confirm or break the read, and the asymmetry. Frame it as thinking - e.g. "early-cycle, sentiment bleak, normalized EPS ~$X, capacity being shut" - never a buy/sell directive.
综合分析：所处周期阶段、标准化收益能力、主导信号、哪些因素会验证或推翻当前判断，以及不对称性。以思考框架呈现，例如：“处于周期早期，市场情绪悲观，标准化EPS约为X美元，产能正被缩减”——绝不给出买入/卖出指令。

Rules

规则

  • Not financial advice. Reasoning and a disposition, never a directive to trade.
  • Normalize, never trust spot. Peak earnings at a low multiple is the trap; trough losses are not by themselves a reason to avoid.
  • The P/E inversion (step 4) is mandatory.
  • Specific, not generic. Tie every tell to a concrete fact and quote it; no textbook recitation.
  • Sentiment is a signal. "This one is different" at the bottom and universal enthusiasm at the top both count - but distinguish a normal cycle from a true structural break.
  • playbook.md
    is the source of truth     for the tells and sectors - keep it growing there, not here.
  • 绝非财务建议：仅提供推理过程和倾向性判断，绝不给出交易指令。
  • 标准化处理，绝不轻信即时数据：峰值收益对应低倍数是陷阱；谷值亏损本身并非回避理由。
  • 必须开展市盈率反转分析（步骤4）。
  • 具体而非笼统：每个信号都需关联具体事实并引用；避免照搬教科书内容。
  • 市场情绪是信号：底部时的“这次不一样”和顶部时的普遍狂热均为信号——但需区分正常周期与真正的结构性突破。
