dcf-model

A discounted-cash-flow (DCF) valuation workflow, which estimates value by converting expected future free cash flow into today's value.

In plain words
What is it for?
Use it to build FCFF or FCFE models, compare scenarios, test sensitivity to key assumptions, and document the resulting value range.
Why use it?
It makes assumptions such as growth, margins, terminal growth, and discount rate explicit instead of presenting one unexplained target value.

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

dcf-model 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 2d 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.

What it actually says

DCF 模型(现金流折现)

何时使用

用户要做显式假设驱动的 DCF / FCFF·FCFE 折现框架,而非同业倍数表或估值球场汇总。边界:相对估值用 @skill:comps-analysis;多方法区间并排用 @skill:football-field。本技能产出 假设透明的折现模型 + 网页报告,完整度标记为 assumption-only

分析架构(投研方法)

  • 问题/假设:在何种增长、利润率、再投资与折现率下,内在价值区间如何?
  • 证据清单:历史财务与现金流(事实)、用户确认的 WACC/g/预测期(假设)、情景结果(模型输出)
  • 多维交叉验证:历史增长 vs 预测增长;FCF 转化 vs 会计利润;终端价值占比是否过高
  • 结论与不确定:价值区间随假设变动;禁止输出「唯一正确目标价」
  • 风险与缺口:缺历史 FCF、无法估净债务、跨市场税率/WACC 不可比
  • 事实 | 假设 | 推断 分栏:历史数字为事实;WACC/g/增长路径为假设;「合理价值带」为推断

数据维度

维度 取数方向 缺失时
标的 search_instruments / ask_user 先确认再建模
概况 get_instrument_profile 业务章从简
财务与利润 get_instrument_financials / get_instrument_income_statement 标明历史基期不足
现金流 get_instrument_cash_flow 改用间接推算并标假设
关键假设 ask_user(WACC、g、预测期、税率等) 禁止静默填「市场共识」
计算固化 opptrix_run + workspace_write 仅聊天展示公式并说明未落盘
交付 list_web_vendorcreate_web 用户只要口头要点时可跳过

步骤

  1. 确认标的与模型口径:FCFF vs FCFE、币种、预测年数。
  2. 拉取历史事实:财务/利润/现金流;整理基期 FCF 与净债务(若可得)。
  3. 收集假设:对 WACC、永续 g、收入/利润率路径等 必须 ask_user;不得假装共识或卖方默认值。
  4. 建模:可用 opptrix_run 计算;关键中间表 workspace_write 便于复用。
  5. 情景与敏感性:基准/乐观/悲观;对 WACC 与 g 做二维敏感。
  6. 交付网页(默认)list_web_vendorcreate_web;已有则 read_web / update_web
  7. 标注 assumption-only:全程区分事实/假设/推断;不可行则写 not-feasible 原因。

网页报告建议目录

  1. 标的与模型口径、数据时效
  2. 历史基期与事实摘要
  3. 显式假设表(WACC、g、增长、税率等)
  4. 预测期现金流与终值拆解
  5. 企业价值 → 股权价值桥(若可得净债务)
  6. 情景与敏感性(事实输出 + 推断解读分栏)
  7. 局限、缺口与复算清单
  8. 免责声明(无买卖建议;非目标价承诺)

禁止

  • 荐股;编造历史数字或「华尔街共识 WACC」
  • 禁止无交付就结束(默认须有 web 产物,除非用户明确只要口头要点)
  • 禁止假装共识:未返回的一致预期/WACC 不得写成市场共识
  • assumption / not-feasible 须诚实降级(缺基期、用户拒给关键假设则中止估值结论)
  • 禁止把单一点估计包装成「公允目标价」

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

dcf-model is a skill published in the GitHub repository Travisun/Opptrix (224 stars, last pushed 4d ago), licensed Apache-2.0. It adds 104 tokens to every session and 1,263 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
