# A股Beta对冲/市场中性策略
## 数据源
```bash
SCRIPTS="$SKILLS_ROOT/cn-stock-data/scripts"
python "$SCRIPTS/cn_stock_data.py" kline --code [CODE] --freq daily --start [日期]
python "$SCRIPTS/cn_stock_data.py" quote --code [CODE]
python "$SCRIPTS/cn_stock_data.py" finance --code [CODE]
```
## Workflow
### Step 1: 计算个股/组合Beta
- 回归法:R_i = α + β × R_m + ε(60日滚动)
- 调整Beta = 0.67 × Raw Beta + 0.33 × 1
### Step 2: 对冲工具选择
- 股指期货(IF/IC/IM/IH)
- ETF融券(如300ETF、500ETF)
- 期权组合
### Step 3: 计算对冲比率
- 全对冲:空头名义值 = 多头名义值 × β
- 部分对冲:根据风险预算调整对冲比例
### Step 4: 基差风险分析
- 期货贴水/升水对对冲成本的影响
- 展期成本估算
### Step 5: 输出
| 维度 | formal | brief |
|------|--------|-------|
| Beta计算 | 多种方法对比 | 当前Beta |
| 对冲方案 | 完整对冲方案 | 推荐工具+比率 |
| 成本分析 | 基差+展期成本 | 年化对冲成本 |
默认风格:brief。
## 关键规则
1. Beta不稳定——需用滚动窗口动态调整
2. A股股指期货长期贴水——对冲成本=贴水+手续费
3. 融券难借且成本高——限制了做空能力
4. 对冲只消除Beta风险——Alpha也可能为负
5. 对冲比例非一成不变——需定期再平衡
## 使用示例
### 示例 1: 基本使用
```python
# 调用 skill
result = run_skill({
"param1": "value1",
"param2": "value2"
})
```
### 示例 2: 命令行使用
```bash
python scripts/run_skill.py --input data.json
```

Playbook for creating and editing uCoz landing pages via MCP tools (`templates_tool`, `ftp_tool`, `modules_tool`). Use for tasks such as: "build a landing page", "update the homepage as a landing page", "create a promo page on the homepage", "add a lead form / menu / SEO to the homepage". Homepage: `page_list`, `page_get`; first publish — `page_update` with full `page_tmpl`; HTML edits after generation — `patch_template` (module_id=2, template_id=1), not `update_template`.
