What it does
Undervalued Stock Screener is an agent skill from Geeksfino/finskills. 扫描A股市场，筛选基本面强劲但市值被低估的上市公司。当用户询问低估值股票、价值投资筛选、A股便宜股票、低PE或低PB公司、基本面强但被低估的公司、或要求运行估值筛选器时使用此技能。
Its SKILL.md is about 470 tokens, which your agent loads only when the skill is triggered. The skill folder holds 4 other files, including reference files (for example `references/output-template.md` and `references/screening-methodology.md`).
It sits in Business, Finance & HR, covering Stock and market analysis. The repository describes itself as: Financial engineering and risk/compliance skills for agents. The licence is Apache-2.0.
When your agent uses it
- Tasks that involve Stock and market analysis
Example prompts
- “/undervalued-stock-screener”
Workflow steps
4 steps, taken from the first numbered list in SKILL.md.
- 筛选范围 — 全市场、特定申万一级行业、主板/创业板/科创板/北交所、或自定义股票池
- 市值范围 — 无限制（默认）、大盘（>500亿）、中盘（100–500亿）、小盘（<100亿）
- 结果数量 — 默认：10家
- 侧重点 — 综合评估（默认）、深度价值（低PB导向）、成长价值（PEG导向）、红利价值
What it can do on your machine
Read from SKILL.md and the folder at commit 8722415. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Undervalued Stock Screener loads about 469 tokens when it runs, and up to ~3k if it reads all its reference files. Until then it costs about 29 tokens; SKILL.md has 86 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

低估值股票筛选器
扮演专业的权益研究分析师。扫描A股市场，筛选出基本面强劲但被市场低估的上市公司。
工作流程
第一步：确定参数
与用户确认：
- 筛选范围 — 全市场、特定申万一级行业、主板/创业板/科创板/北交所、或自定义股票池
- 市值范围 — 无限制（默认）、大盘（>500亿）、中盘（100–500亿）、小盘（<100亿）
- 结果数量 — 默认：10家
- 侧重点 — 综合评估（默认）、深度价值（低PB导向）、成长价值（PEG导向）、红利价值
默认参数：全市场、无市值限制、10家、综合评估。
第二步：应用筛选条件
对全部候选股票应用以下筛选条件。详细标准参见 references/screening-methodology.md。
| 筛选条件 | 标准 |
|---|---|
| PE估值 | 滚动PE低于所属申万行业中位数 |
| PB估值 | PB低于所属行业中位数（配合ROE筛选） |
| 营收与利润增长 | 近3–5年营收和归母净利润复合增长率为正 |
| 资产负债率 | 低于行业中位数（金融行业除外） |
| 自由现金流 | 正值且近3年累计为正 |
| ROIC/ROE | ROE高于行业平均水平 |
自动排除：ST/*ST公司、上市不满2年的公司、近12个月净利润为负的公司。
第三步：深度分析
对通过筛选的股票逐一分析。关注：
- 业务概述 — 主营业务、竞争优势（护城河）、行业地位
- 低估原因分析 — 为什么市场给出了低估值
- 核心风险 — 可能使低估合理化的因素
- 估值区间估计 — 基于多种方法的合理估值范围
第四步：编制报告
以结构化报告呈现，格式参见 references/output-template.md。
筛选条件摘要
| 条件 | 过滤目的 | A股特殊考量 |
|---|---|---|
| PE < 行业中位数 | 排除过度溢价公司 | A股整体PE中枢高于成熟市场，使用行业相对法 |
| PB < 行业中位数 | 识别资产折价 | 银行/地产PB长期破净需额外判断 |
| 营收/利润正增长 | 排除衰退中的"价值陷阱" | 关注扣非净利润（排除一次性损益） |
| 低资产负债率 | 排除财务风险 | 金融行业需使用行业专属指标 |
| 正自由现金流 | 确认盈利质量 | 高应收账款/存货的公司需警惕 |
| 高ROE/ROIC | 确认资本效率 | 关注杜邦分析，区分高杠杆驱动vs真实盈利能力 |
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
- A股估值中枢偏高：A股历史估值中枢高于美股等成熟市场（部分因审批制/注册制初期供给不足），因此使用行业相对估值法更为适用。
- 扣非净利润：A股公司非经常性损益项目（政府补贴、投资收益、资产处置）较多，应使用扣非后净利润评估持续盈利能力。
- 壳价值与注册制：注册制全面推行后壳价值逐渐下降，传统的"小盘股溢价"正在消退。
- 行业差异极大：银行PB长期在0.5–0.8x不代表低估（可能反映资产质量担忧），科技行业高PE可能合理（高增长预期）。须在行业内部比较。
- 国企vs民企：国企可能存在"国企折价"（治理效率担忧），但近年国企改革正在缩小这一差距。
- 非投资建议：低估值筛选仅为信息整理工具，不构成投资建议。"便宜"不等于"值得买"。
