Workflow

工作流程

Step 1: Confirm Screening Parameters

步骤1：确认筛选参数

Before screening, confirm with the user:
  1. Number of stocks to identify (default: 10)
  2. Market scope — US only, global, or specific regions/exchanges
  3. Sector preferences — any sectors to include or exclude
  4. Market cap range — large-cap, mid-cap, small-cap, or all
  5. Additional filters — any custom criteria beyond the defaults
If the user wants defaults, proceed with the standard filters below.
筛选前，与用户确认以下内容：
  1. 要识别的股票数量（默认值：10只）
  2. 市场范围——仅美国、全球，或特定地区/交易所
  3. 行业偏好——需包含或排除的行业
  4. 市值范围——大盘股、中盘股、小盘股，或全部
  5. 额外筛选条件——除默认条件外的任何自定义标准
如果用户选择默认值，则使用以下标准筛选条件进行操作。

Step 2: Apply Screening Filters

步骤2：应用筛选指标

Apply ALL of the following quantitative filters. See references/screening-methodology.md for detailed criteria, thresholds, and edge cases.
FilterCriterion
ValuationP/E ratio below industry average
GrowthConsistent revenue and earnings growth over 3–5 years
LeverageDebt-to-equity ratio below sector median
Cash FlowPositive and growing free cash flow

回报率投入资本回报率（ROIC）高于行业平均水平
上涨空间分析师共识上涨空间≥30%

Step 3: Deep-Dive Analysis

步骤3：深度分析

For each qualifying company, perform a deep-dive analysis covering:
  1. Business Overview — What the company does, its market position, competitive moat
  2. Why It Appears Undervalued — Specific catalysts, market misperception, or temporary headwinds causing the discount
  3. Key Risks — Macro, industry, and company-specific risks that could impair the thesis
  4. Estimated Intrinsic Value Range — Using DCF, comparable multiples, or asset-based approaches as appropriate
See references/output-template.md for the structured report format.
对每一家符合条件的公司，进行深度分析，涵盖以下内容：
  1. 业务概述——公司业务范围、市场地位、竞争护城河
  2. 被低估原因——导致估值折价的具体催化剂、市场误判或暂时性不利因素
  3. 主要风险——可能影响投资逻辑的宏观、行业及公司特定风险
  4. 预估内在价值区间——根据情况使用折现现金流（DCF）、可比倍数或资产基础法进行估算
结构化报告格式请参考references/output-template.md。

Step 4: Compile and Present

步骤4：整理与呈现

Present findings in a structured report:
  1. Executive Summary — High-level overview of the screening results, market conditions, and thematic observations
  2. Screening Criteria Summary — Table of filters applied
  3. Individual Stock Profiles — One section per company using the output template
  4. Comparative Table — Side-by-side metrics for all identified stocks
  5. Disclaimers — Standard investment research disclaimers
将研究结果整理为结构化报告：
  1. 执行摘要——筛选结果、市场环境及主题观察的高层概述
  2. 筛选标准摘要——所应用筛选指标的表格
  3. 个股概况——每家公司单独成节，使用上述输出模板
  4. 对比表格——所有识别出股票的关键指标对比表
  5. 免责声明——标准的投资研究免责声明

Important Guidelines

重要准则

  • Data currency: Always state the date/period of data used. Acknowledge any data limitations.
  • Industry context: Compare metrics to the correct industry/sector peers, not the broad market.
  • Qualitative overlay: Numbers alone are insufficient. Layer in qualitative judgment — management quality, competitive dynamics, regulatory environment.
  • Avoid bias: Do not favor popular or well-known names. Include lesser-known companies if they meet criteria.
  • Risk-first mindset: For each stock, honestly assess what could go wrong. A good screener is not a buy list.
  • Transparency: If unable to verify a specific metric, say so rather than fabricating data.
  • 数据时效性：始终说明所使用数据的日期/时段，同时告知数据存在的局限性。
  • 行业背景：将指标与对应行业/板块的同行对比，而非与整体市场对比。
  • 定性补充：仅靠数据是不够的，需结合定性判断——管理层质量、竞争格局、监管环境。
  • 避免偏见：不要偏好知名公司，若符合标准，也需纳入知名度较低的公司。
  • 风险优先思维：对每只股票，诚实地评估可能出现的问题。优秀的筛选工具不等于买入清单。
  • 透明度：若无法验证特定指标，需明确说明，而非编造数据。
