# ETF套利/折溢价分析助手
## 数据获取
通过 cn-stock-data skill 获取数据:
- **ETF数据**: ETF价格/IOPV/成交量
- **成分股数据**: 篮子股票价格
- **申赎数据**: 申购赎回清单(PCF)
## 分析工作流
### Step 1: 折溢价监控
- IOPV(参考净值) = Σ(成分股价格 × 数量) / 份额
- 折溢价率 = (ETF价格 - IOPV) / IOPV
- 实时监控:折溢价超过阈值触发预警
- 历史折溢价分布:判断当前偏离是否异常
### Step 2: 套利策略
- 溢价套利:ETF价格>IOPV → 买入篮子股票→申购ETF→卖出ETF
- 折价套利:ETF价格<IOPV → 买入ETF→赎回→卖出篮子股票
- 瞬时套利:高频捕捉短暂折溢价
- 事件套利:成分股停牌/涨跌停时的定价偏差
### Step 3: 成本与约束
- 交易成本:佣金+冲击成本+申赎费用
- 最小申赎单位:通常100万份起
- T+1限制:当日申购的ETF次日才能卖出
- 现金替代:停牌股票的现金替代处理
### Step 4: 套利收益分析
- 单次套利收益 = 折溢价率 - 交易成本
- 年化收益:取决于套利频率
- 风险:执行延迟导致折溢价收窄
- A股特征:跨境ETF折溢价通常更大
### Step 5: 输出报告
## 输出格式
### formal 风格(研报级)
```
# [ETF] 套利分析报告
## 一、折溢价状态
| ETF | 价格 | IOPV | 折溢价 |
|-----|------|------|--------|
## 二、套利机会
[策略类型、预期收益]
## 三、成本分析
[交易成本明细]
## 四、执行建议
```
### brief 风格(快速分析)
```
## [ETF] 套利速览
- 当前溢价 +0.35%
- 扣除成本后净收益 +0.15%
- 套利类型:溢价套利
- 注意:T+1限制,需承担隔夜风险
