# A股多策略组合/策略配置分析
## 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: 策略池定义
列出候选策略(动量/价值/均值回归/事件驱动等),明确各策略逻辑。
### Step 2: 单策略回测
分别回测各策略的收益率序列、夏普比率、最大回撤。
### Step 3: 策略相关性分析
计算策略间收益率相关矩阵,识别低相关/负相关策略组合。
### Step 4: 策略权重优化
- 等权配置
- 风险平价(按波动率倒数加权)
- 最大夏普比率优化
- 最小相关性组合
### Step 5: 输出
| 维度 | formal | brief |
|------|--------|-------|
| 策略表现 | 各策略完整回测 | 夏普/回撤 |
| 相关矩阵 | 完整相关性热力图 | 平均相关系数 |
| 组合效果 | 多种配置方案对比 | 推荐配置 |
默认风格:brief。
## 关键规则
1. 低相关性策略组合才有分散化价值
2. 策略相关性在极端行情下会趋同(尾部相关性上升)
3. A 股策略容量有限——小盘策略尤其需要考虑冲击成本
4. 定期再平衡(月度/季度)优于漂移不管
5. 策略失效检测:滚动夏普比率跌破阈值时降权
## 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
```

Manage Globalize translation resources using the CLI. Use this skill when the user asks to create a translation project, add or remove languages, connect a GitHub or GitLab repository, manage glossaries or style guides, invite team members, manage API keys, or perform any Globalize platform operation. Also use when the user mentions managing translations, translation workflow, or wants to "set up translations for this repo." This skill assumes the CLI is already installed and authenticated — ...
