lean-etf-thematic-baskets

lean-etf-thematic-baskets is a skill for Claude Code from Travisun/Opptrix. It costs 81 tokens per session (1,371 once invoked), scanned A, original, Apache-2.0.

A workflow for comparing thematic ETF baskets, meaning groups of exchange-traded funds built around related industries or investment themes. It examines whether their holdings and exposures overlap.

In plain words
What is it for?
Use it to compare several theme baskets, inspect their largest holdings, calculate overlap, and assess concentration and consistency with each theme.
Why use it?
It reveals when different theme labels lead to similar portfolios, which can make diversification smaller than it appears. The comparison uses Chinese-market sector and ETF data and treats theme labels as claims to check against holdings.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

lean-etf-thematic-baskets scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 6d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

LEAN 主题ETF篮

方法溯源 QuantConnect LEAN 社区算法/示例思路;本技能是平台工具编排的投研工作流禁止假装跑完整 LEAN 引擎或输出 LEAN 回测曲线、订单日志冒充引擎结果。实际取数与计算仅限 Opptrix 工具(行情/财务/opptrix_run 沙盒等)。

何时使用

用户要比较多个国内主题场内 ETF 篮子的持仓重叠、集中度与主题一致性(LEAN 方法溯源,非美股原版照搬)。默认交付可预览网页。

边界:单只 ETF 研究用 @skill:etf-research;单 ETF 成分宇宙用 @skill:lean-etf-constituents;政策主题叙事映射用 @skill:theme-policy-map

A股适配(默认)

  • 默认市场 CN(A股 / 场内 ETF)。用户点名美股/港股再切换,并声明数据口径与微观结构差异。
  • 主题宇宙:默认 申万/概念板块get_sector_*)+ 行业 ETF 代理,而非美股主题 ETF 清单。
  • 用户点名海外主题再切换并声明数据差异。
  • 融券受限 → 主题多空改为「多头排序 / 多头+防御 ETF」。
  • 不可硬适配或数据缺口时:首页横幅写清完整度(partial 或更严)+ 必要时 ask_user

分析架构(投研方法)

  • 问题/假设:各主题篮暴露是否重叠?宣称主题与持仓是否一致?
  • 证据清单:多只 ETF 概况与持仓、重叠矩阵(可沙盒算)
  • 多维交叉验证:主题标签 vs 前十大;篮间 Jaccard/权重重叠
  • 结论与不确定:重叠高≠冗余必减仓;主题叙事可漂移
  • 微观/制度风险:涨跌停钝化、T+1、ST/停牌、融券受限(及相关会计口径差异);不得按美股连续可成交或自由做空假设叙事
  • 事实 | 假设 | 推断 分栏强制

数据维度

维度 取数方向 缺失时
主题与 ETF 清单 ask_user / get_etf_list 先确认篮定义
各篮概况/持仓 get_etf_profile / get_etf_holdings 缺持仓的篮单独标注
重叠计算 opptrix_run(可 workspace_write 仅列示前十大对照
交付 list_web_vendorcreate_web 可跳过口头要点
A股主题代理 get_sector_* + 行业 ETF 主题无板块映射则 ask_user / assumption-only

步骤

  1. 确认默认 CN:标的/宇宙为 A股或场内 ETF(用户点名其他市场再切换并声明差异)。应用涨跌停/T+1/融券受限等微观约束(见 A股适配)。
  2. 确认主题与 ETF 映射:每主题至少一只可解析 ETF
  3. LEAN 溯源边界:灵感来自主题篮/ETF 轮动示例;不跑 LEAN
  4. 拉取各篮持仓:对齐报告日
  5. 重叠与集中度:沙盒算重叠表;事实/推断分栏
  6. 交付网页(默认)create_web

网页报告建议目录

  1. 范围:默认 A股/场内 ETF + LEAN 溯源
  2. 主题→ETF 映射表
  3. 各篮持仓与时效
  4. 篮间重叠/集中度
  5. 主题一致性交叉验证
  6. 事实 / 假设 / 推断分栏
  7. A股适配与限制(默认 CN;微观结构/代理/完整度)
  8. 免责声明(无买卖建议)

禁止

  • 荐股、目标价、仓位建议;编造未返回数字
  • 编造持仓重叠或假装完整主题库
  • 禁止假装跑完整 LEAN 引擎或伪造 LEAN 日志/回测净值
  • 禁止无交付就结束(默认须有 web 产物,除非用户明确只要口头要点)
  • 禁止把美股成分/ETF 清单不经映射直接当 A股结果
  • 禁止假设可自由融券做空
