quant-factor-screener is a Claude Code skill that ranks A-share stocks using a six-factor quantitative framework for developers and quants who need systematic equity screening beyond manual watchlists.

About

quant-factor-screener is a geeksfino/finskills agent skill that acts as a quantitative equity analyst for China's A-share market. It scores stocks across six academic factors—value, momentum, quality, low volatility, size, and growth—with equal default weights and percentile-based composite rankings. Developers configure universes such as CSI 300, CSI 500, CSI 1000, or full A-shares, apply optional industry-neutral constraints, and receive a default top-20 ranked list with macro factor-timing context. The skill suits engineers building quant research assistants, fintech dashboards, or automated screening pipelines that need repeatable multi-factor scoring rather than ad-hoc stock picks. Install via npx skills add geeksfino/finskills --skill quant-factor-screener.

How do you screen A-shares with multi-factor scoring?

For development and infrastructure management.

Who is it for?

Quant developers and fintech engineers building A-share screening workflows who need repeatable six-factor ranking with configurable universes and weights.

Skip if: Developers seeking US or European equity screening, live brokerage execution, or infrastructure deployment guidance.

When should I use this skill?

A developer asks to screen A-share stocks, rank equities by value/momentum/quality factors, or run a multi-factor quant screener on CSI indices.

What you get

Ranked A-share stock lists with six-factor composite scores, industry-neutral filters, and macro factor-timing assessments.

By the numbers

  • Scores stocks across 6 quantitative factors with equal default weights
  • Default output returns top 20 ranked stocks from configurable universes

量化因子筛选器

扮演量化权益分析师。使用基于学术因子研究的系统化多因子框架筛选A股——对价值、动量、质量、低波动、规模和成长因子进行评分和排名。

工作流程

第一步:确定参数

与用户确认:

输入选项默认
选股池沪深300 / 中证500 / 中证1000 / 全A / 自定义中证800
因子全部6个或特定因子全部
因子权重等权或自定义等权
行业约束行业中性或不约束行业中性
结果数量前N只前20只
宏观研判当前因子择时评估自动判断
排除项行业、概念、特定个股

第二步:计算因子得分

对选股池中每只股票计算各因子得分。详细定义参见 references/factor-methodology.md

因子主要指标默认权重
价值盈利收益率、PB倒数、FCF收益率、EV/EBITDA1/6
动量12-1月价格动量、盈利预期修正动量1/6
质量ROE、盈利稳定性、低杠杆、应计质量1/6
低波动已实现波动率(1年)、Beta、下行偏差1/6
规模市值(越小得分越高)1/6
成长营收增速、盈利增速、利润率扩张1/6

对每个因子: 1. 计算每只股票的原始指标 2. 在行业内(行业中性时)或全选股池内排名 3. 将排名转换为百分位得分(0–100) 4. 将子指标合成为综合因子得分

第三步:合成得分

综合得分 = Σ (因子权重 × 因子得分)

按综合得分从高到低排列所有股票。

第四步:因子择时评估

评估当前宏观环境及其对因子表现的影响。参见 references/factor-methodology.md

宏观环境利好因子不利因子
经济复苏初期规模、动量低波动
经济扩张中期动量、成长价值
经济扩张末期质量、价值规模
经济下行低波动、质量动量、规模
经济触底价值、规模、动量低波动

基于当前研判,提供因子择时叠加以调整权重。

第五步:因子拥挤度分析

评估热门因子是否过度拥挤:

信号拥挤不拥挤
估值价差因子内高低分组估值差收窄估值差扩大
因子收益相关性高(许多人跟随相同信号)
ETF/基金资金流入因子相关产品大量净申购净赎回
媒体/分析师关注被广泛讨论被忽视

标记拥挤的因子——收益可能被压缩。

第六步:呈现结果

格式参见 references/output-template.md

1. 宏观环境研判 — 当前阶段和因子择时观点 2. 因子拥挤度面板 — 哪些因子拥挤/不拥挤 3. 精选个股表 — 前N只股票的各因子得分和综合得分 4. 行业分布 — 精选结果的行业分布 5. 因子暴露汇总 — 精选列表的整体因子特征 6. 个股简介 — 每只精选个股的简要画像 7. 风险提示 — 因子回撤历史和当前风险 8. 免责声明

数据增强

如需实时市场数据支撑分析,请使用金融数据工具包技能(findata-toolkit-cn)。该工具包提供A股实时行情、财务指标、董监高增减持、北向资金、宏观数据等功能,所有数据源免费,无需API密钥。

重要注意事项

  • 因子不是万能的:因子有长期跑输的时候。A股的价值因子在2019–2020年严重跑输。动量因子会周期性崩溃。设定合理预期。
  • 行业中性很重要:不做行业约束的因子筛选常常产出伪装成因子赌注的行业集中赌注。
  • A股因子特殊性:低波动异象在A股非常显著;动量因子因散户主导的市场结构而表现不同;小盘因子溢价受壳价值和流动性溢价影响。
  • 换手率因子:A股中换手率是一个独特且有效的负向因子(低换手率→高收益),这在成熟市场中不那么显著。
  • 多因子更稳健:没有单一因子永远有效。组合因子可降低回撤、平滑收益。
  • 交易成本:动量策略换手率高。需考虑现实的交易成本(印花税0.05%+佣金)。
  • 非个人化建议:因子筛选是分析工具,不构成投资建议。个人情况各异。
