风险预算/风险平价策略助手
SkillDev toolsOnce added, your AI can build risk budget and risk parity portfolios for Chinese A-shares. Ask about risk budgeting, risk parity, risk contribution, or equal-risk allocation and it pulls the data it needs through cn-stock-data, then constructs a portfolio balanced by risk. You can ask for the results in a formal or a brief style.
Available today. Use it from your connected AI after setup.
No other account needed.
Add the skill, then ask your AI to build a risk parity or risk budget portfolio for A-shares. It gets its data through cn-stock-data, so make sure that is available as well.
Then ask your AI: use the 风险预算/风险平价策略助手 skill
What your AI can do with it
- Build risk parity portfolios where each A-share holding contributes equally to total risk
- Build risk budget portfolios that give each holding its assigned share of risk
- Pull the A-share data needed for the calculations through cn-stock-data
- Recognize requests phrased as risk budget, risk parity, risk contribution, or equal-risk allocation
- Present results in either a formal or a brief style

数据获取
通过 cn-stock-data skill 获取数据:
- 持仓数据: 个股/资产权重
- 协方差矩阵: 资产间的风险结构
- 风险预算: 各资产的目标风险贡献
分析工作流
Step 1: 风险贡献分解
- 边际风险贡献 MCTR_i = ∂σ_p/∂w_i
- 风险贡献 RC_i = w_i × MCTR_i
- 风险贡献占比 = RC_i / σ_p
- 验证:Σ RC_i = σ_p (Euler分解)
Step 2: 风险预算设定
- 等风险预算:每个资产风险贡献相等
- 自定义预算:按投资观点分配风险
- 行业风险预算:控制行业层面的风险贡献
- 因子风险预算:控制因子层面的风险暴露
Step 3: 最优权重求解
- 目标:使实际风险贡献匹配预算
- 优化算法:序列二次规划(SQP)/牛顿法
- 约束:权重非负/权重之和=1/个股上限
- 迭代求解:直到风险贡献偏差<阈值
Step 4: 风险平价实施
- 再平衡频率:月度/季度
- 杠杆选择:风险平价通常需要杠杆提升收益
- 交易成本:再平衡的换手成本
- A股实施:无杠杆版本的风险平价
Step 5: 输出报告

formal 风格(研报级)
# 风险预算分析报告
## 一、风险贡献
| 资产 | 权重 | RC | RC占比 | 预算 |
|------|------|-----|--------|------|
## 二、最优权重
[风险预算下的最优配置]
## 三、组合特征
[预期收益/波动率/Sharpe]
## 四、再平衡建议
brief 风格(快速分析)
## 风险预算速览
- 当前:前3大持仓贡献70%风险
- 目标:等风险贡献(每只10%)
- 调整:减持高波动标的,增持低波动
- 预期Sharpe提升 +0.2
