组合优化 Skill
Skill ID
a_share.portfolio_optimization.v1
功能定位
在约束下优化组合权重,控制跟踪误差、集中度、换手和冲击成本。
适用场景
组合再平衡、风险预算调整。
必填输入
as_of_date: 分析截止日期,必须使用当时已公开可得数据。object_type:stock/industry/portfolio/market/theme/factor。object_id: 股票代码、行业名称、组合ID、主题名称或因子名称。investment_horizon:intraday/1w/1m/3m_6m/1y_3y。benchmark: 沪深300、中证500、中证1000、行业指数或自定义基准。data_bundle: 已加载的数据清单、来源、时间戳和质量评分。
可选输入
portfolio_context: 当前持仓、成本、权重、产品约束。risk_budget: 单票、行业、风格、流动性和回撤约束。previous_thesis: 历史投资假设、上次评级、上次目标价。manual_notes: 研究员补充信息或人工调研纪要。
依赖 Skill

通用执行流程
- 校验输入参数,确认
as_of_date、对象、投资期限、基准、股票池和组合约束。 - 检查依赖数据是否齐全,并调用或引用数据质量审计结果。
- 按本 Skill 的专业框架进行分析,不跳步,不省略反证。
- 对所有关键判断打分:事实强度、影响程度、可验证性、时效性、组合相关性。
- 生成结构化 JSON、Markdown 报告和审计日志。
- 给出下游建议:进入哪个 workflow、是否需要人工复核、何时再次更新。
本 Skill 专业步骤
- 设定目标函数:最大信息比率、最小波动、最大效用或约束收益。
- 纳入协方差矩阵、行业和风格暴露、交易成本。
- 输出优化权重、边际贡献、敏感性和不可行约束。
判断与打分框架
fact_strength: 事实强度,公告/财报/交易所数据最高,二手新闻和传闻最低。impact_score: 对盈利、估值、现金流、风险偏好、组合风险的影响程度。time_sensitivity: 信息有效期和是否需要盘中处理。verification_score: 是否可被其他数据源交叉验证。portfolio_relevance: 对当前组合、候选池、禁投池的影响程度。
标准输出
同时输出两种形态:
result.json:供下游 Agent / workflow 读取;report.md:供投研人员阅读。
result.json 至少包含:

报告结构
# 组合优化报告
## 1. 一句话结论
## 2. 核心证据
## 3. 关键数据与图表建议
## 4. 正方观点
## 5. 反方观点
## 6. 风险与证伪条件
## 7. 对估值/盈利/组合/交易的影响
## 8. 后续跟踪指标
## 9. 人工复核事项
## 10. 审计日志
强制约束
- 不得把传闻、新闻标题、管理层口头表述当成确定事实;所有关键结论必须标注证据来源与时间戳。
- 不得使用未来函数:财务数据、公告、研报、价格、指数成分必须以
as_of_date当时已公开可得为准。 - 不得绕过人工复核直接给出实盘下单指令;涉及买入、卖出、加仓、减仓、禁投、强制平仓的结论必须输出
human_review_required: true。 - 数据缺失、数据冲突、来源不可靠时,必须降低置信度,并列出不可验证项。
- 对 ST、*ST、停牌、退市整理、重大违法、财务造假、流动性不足标的,必须优先触发风险检查。
- 报告中必须同时给出正方观点、反方观点、证伪条件和后续跟踪指标。
下游流转
- 若输出影响投资评级、仓位或禁投状态,必须传递给
investment_memo、portfolio_risk_monitor和compliance_check。 - 若发现数据异常,必须回流给
data_quality_audit或data_conflict_resolution。 - 若发现投资假设变化,必须回流给
thesis_review。
