# 期权定价/BSM模型分析助手
## 数据获取
通过 cn-stock-data skill 获取数据:
- **期权数据**: 市场价格/行权价/到期日
- **标的行情**: 现价/股息率
- **利率数据**: 无风险利率曲线
## 分析工作流
### Step 1: BSM定价
- 欧式期权BSM公式:C = S*N(d1) - K*e^(-rT)*N(d2)
- 输入参数:S(标的价)、K(行权价)、T(到期时间)、r(利率)、σ(波动率)
- 股息调整:连续股息率q的修正
- 理论价格 vs 市场价格的偏差分析
### Step 2: 数值定价方法
- 二叉树模型:美式期权定价
- 蒙特卡洛模拟:路径依赖期权
- 有限差分法:偏微分方程数值解
- 各方法的精度与计算效率对比
### Step 3: 定价偏差分析
- 市场价格 vs 理论价格:溢价/折价
- 偏差来源:流动性溢价/供需不平衡/模型误差
- 套利机会识别:Put-Call Parity偏离
- 波动率微笑对BSM定价的修正
### Step 4: 高级定价模型
- Heston随机波动率模型
- SABR模型:波动率曲面拟合
- 局部波动率模型:Dupire方程
- 跳跃扩散模型:Merton Jump-Diffusion
### Step 5: 输出报告
## 输出格式
### formal 风格(研报级)
```
# [标的] 期权定价分析报告
## 一、BSM定价
| 合约 | 市场价 | 理论价 | 偏差 |
|------|--------|--------|------|
## 二、定价偏差
[偏差分析、套利机会]
## 三、高级模型
[Heston/SABR定价对比]
## 四、交易建议
```
### brief 风格(快速分析)
```
## [标的] 定价速览
- BSM理论价 0.285,市场价 0.295
- 溢价 +3.5%,流动性溢价为主
- Put-Call Parity偏差 0.2%,无套利
- Heston定价 0.290,更接近市场
```
