## Codex adapter note

This skill is generated from `berkshire-financial-data` so Claude Code and Codex users share one canonical workflow.

- Treat `$ARGUMENTS` as the user's request in the current Codex thread.
- When the source mentions Claude-only surfaces such as Task, Agent, WebSearch, Bash, Read, or Write, use the closest Codex capability available in this session: subagents when available, web search when needed, shell commands for local tools, and normal file edits for workspace files.
- Use shared project tools from `tools/` in this repository. Prefer running commands from the repository root with paths like `python3 .claude/skills/berkshire-shared/tools/financial_rigor.py ...`; if the current thread starts outside the repo, locate the actual checkout path first instead of assuming a fixed home-directory path.
- Before starting research, run the `date` command to confirm today's date; treat it as the baseline for "latest" data and state the data cutoff date in the report header. Never assume the current date from training data.
- Preserve the research quality rules from `AGENTS.md`: cross-check financial data, use exact arithmetic tools for valuation/math, and clearly label uncertainty and source gaps.

# 财务数据获取与交叉验证规范

本规范适用于所有涉及企业财务数据的研究。**每个关键数据必须来自两个独立来源,误差>1%须标记。**

---

## 数据源优先级

### 美股(PDD、腾讯ADR、网易ADR等)

| 优先级 | 来源 | URL | 获取方式 |
|--------|------|-----|---------|
| 1(主) | **macrotrends** | macrotrends.net/stocks/charts/{ticker} | 直接访问,无需注册 |
| 2(副) | **stockanalysis** | stockanalysis.com/stocks/{ticker}/financials | 直接访问,无需注册 |
| 原始一手 | SEC EDGAR | sec.gov/cgi-bin/browse-edgar | 10-K / 10-Q 原文 |

### 港股(腾讯0700、网易9999、美团3690等)

| 优先级 | 来源 | URL | 获取方式 |
|--------|------|-----|---------|
| 1(主) | **aastocks** | aastocks.com/tc/stocks/analysis/company-fundamental | 直接访问 |
| 2(副) | **macrotrends**(ADR代码) | 腾讯用TCEHY,网易用NTES | 直接访问 |
| 原始一手 | HKEX披露易 | hkexnews.hk | 年报PDF |

### A股(三七互娱、吉比特等)

| 优先级 | 来源 | URL | 获取方式 |
|--------|------|-----|---------|
| 1(主) | **东方财富** | eastmoney.com → 搜股票代码 → 财务报表 | 直接访问 |
| 2(副) | **巨潮资讯** | cninfo.com.cn | 原始年报/季报PDF |

---

## 执行规范

### 第一步:获取数据

对每个财务指标(收入、净利润、毛利率、经营现金流、资产负债率等),分别从**来源1**和**来源2**取数。

### 第二步:误差计算与标记

```
误差率 = |来源1数值 - 来源2数值| / 来源1数值 × 100%
```

| 误差 | 处理方式 |
|------|---------|
| ≤ 1% | ✅ 一致,取来源1数值,标注两个来源 |
| 1% ~ 5% | ⚠️ 标记"数据存在差异",注明两个数值,说明可能原因(汇率/会计口径) |
| > 5% | ❌ 标记"数据存在重大差异",必须查原始财报核实,不得直接使用 |

### 第三步:数据呈现格式

每个关键数据必须按以下格式标注:

```
收入:1,239亿元 ✅
  - macrotrends: 1,241亿元
  - stockanalysis: 1,237亿元
  - 误差: 0.3%
```

差异示例:
```
净利润:245亿元 ⚠️ 数据存在差异
  - macrotrends: 245亿元(GAAP)
  - stockanalysis: 278亿元(Non-GAAP)
  - 误差: 13.5% — 原因:会计口径不同(GAAP vs Non-GAAP)
```

---

## 常见差异原因(不一定是数据错误)

| 原因 | 说明 |
|------|------|
| GAAP vs Non-GAAP | 最常见,尤其是利润类数据 |
| 汇率换算 | 港币/人民币/美元换算时间点不同 |
| 财年定义 | 自然年 vs 财年(如苹果财年10月结束) |
| 合并口径 | 是否含少数股东权益 |
| 数据更新滞后 | 某平台尚未更新最新一期财报 |

---

## 特别规则

1. **未上市公司**(米哈游、莉莉丝等):只有一手数据来源时,数据前标记 `[估计]`,不执行交叉验证
2. **季度数据 vs 年度数据**:优先使用年度数据做交叉验证,季度数据部分来源可能有滞后
3. **原始财报优先**:若两个来源均与原始财报(10-K/年报PDF)不符,以原始财报为准,标记来源错误

---

## 股价与复权(历史序列必读)

价格有三种口径,混用会让历史股价位置、长期涨幅、历史估值分位全部失真:

| 口径 | 含义 | 用途 |
|------|------|------|
| 不复权 | 实际成交价,除权除息日跳空 | 仅用于"当前时点"快照 |
| 前复权 | 以最新价为基准回调历史价 | 历史股价对比、N年涨幅、历史PE band 一律用它 |
| 后复权 | 以上市首日为基准前推 | 计算历史总回报/年化收益 |

规则:

1. 涉及历史价格的分析统一用**前复权**,且同一分析内**不得混用**复权与不复权来源。
2. 当前市值/当前PE 用**当前实际股价 × 当前总股本**即可,与复权无关——复权只影响历史序列。
3. 跨越拆股/大比例送转的每股指标(历史EPS、历史股价),必须复权还原后再同比。
4. 总回报/年化收益需计入分红(后复权已含),只看价格涨幅会低估。
5. 增发/回购后市值验算以最新总股本为准(`financial_rigor.py verify-market-cap` 偏差>5% 会提示核对)。
