Workflow

Step 1: Define Screen Criteria

Investment philosophy alignment:

  • Value vs Growth vs GARP vs Momentum
  • Market cap preference (large / mid / small)
  • Sector focus or sector-agnostic
  • Liquidity requirements (turnover threshold)
  • Risk tolerance (volatility, leverage, earnings stability)

Screen parameters (A-share specific):

ParameterTypical RangeNotes
PE (TTM)5-50xAvoid negative PE
PB0.5-5x<1x may indicate distress
PS0.5-5xFor high-growth unprofitable
Market cap>50亿Liquidity threshold
Daily turnover>5000万Tradability
ROE>10%Quality filter
Debt/Equity<100%Financial health
Revenue growth>10%Growth filter
EPS growth>15%Earnings momentum

Step 2: Quantitative Screens

Screen 1: Deep Value (深度价值)

Filters:
- PE (TTM) < 15x AND PB < 1.5x
- ROE > 10% (past 3 years average)
- Debt/Equity < 80%
- Revenue growth > 0% (not declining)
- Market cap > 30亿

Output: Value candidates with potential mispricing

Screen 2: Growth at Reasonable Price (GARP)

Filters:
- PEG < 1.0 (PE / growth rate)
- Revenue growth > 20%
- Gross margin > 30%
- ROE > 15%
- Market cap > 100亿

Output: Quality growth at reasonable multiples

Screen 3: Momentum (趋势跟踪)

Filters:
- Price above 20-day MA AND 60-day MA
- Price within 10% of 52-week high
- Volume above 20-day average
- RSI between 40-70 (not overbought)
- Upward earnings revision

Output: Momentum names in uptrends

Screen 4: Turnaround (困境反转)

Filters:
- Recent loss or margin compression
- New management / strategy announced
- Order book recovering
- Debt restructuring completed
- Insiders buying

Output: Potential turnaround candidates

Screen 5: Dividend Yield (高股息)

Filters:
- Dividend yield > 3%
- Payout ratio < 60%
- FCF positive and stable
- Debt/Equity < 100%
- Stable earnings history

Output: High-quality income names

Screen 6: Special Situations (事件驱动)

Filters:
- Lock-up expiry within 3 months (限售解禁)
- M&A announcement pending
- Regulatory catalyst (集采结果, etc.)
- Index inclusion/exclusion
- STAR/ChiNext eligibility

Output: Event-driven opportunities

Step 3: Thematic Research

Identify emerging themes:

Theme TypeExamples (A-share)Data Sources
Policy-driven国产替代, 新基建, 双碳政策文件, 部委公告
TechnologyAI应用, 自动驾驶, 机器人技术进展, 订单公告
Demographics老龄化, 少子化人口数据, 消费数据
Consumption消费升级, 国货崛起零售数据, 品牌调研
Industrial高端制造, 专精特新行业数据, 政策

Thematic screening approach:

  1. Define theme and investable universe
  2. Map A-share companies to theme
  3. Rank by exposure and quality
  4. Identify pure-plays vs beneficiaries

Step 4: Technical Analysis

A-share technical considerations:

IndicatorUse
均线 (Moving averages)Trend direction (5/10/20/60/120 day)
MACDMomentum and trend changes
RSIOverbought/oversold
KDJShort-term momentum
成交量 (Volume)Confirmation of moves
龙虎榜Institutional activity
北向资金Foreign flows

Chart patterns to watch:

  • 突破 (breakout) — above resistance
  • 回踩 (pullback to support) — entry opportunity
  • 双底/头肩 (double bottom/head & shoulders) — reversal signals
  • 量价背离 (volume-price divergence) — trend exhaustion

Step 5: Fundamental Deep Dive

For each candidate:

  1. Business model review: How does company make money?
  2. Financial health: Balance sheet, cash flow, earnings quality
  3. Competitive position: Market share, moat, pricing power
  4. Management quality: Track record, capital allocation
  5. Valuation: vs peers, vs history, vs international peers
  6. Catalyst: What could re-rate the stock?

Red flag checklist:

  • 商誉占比过高 (>30% of equity)
  • 应收账款增速 > 收入增速
  • 经营现金流持续为负
  • 大股东质押比例过高 (>50%)
  • 审计意见非标准无保留
  • 频繁变更会计师事务所
  • 关联交易占比高

Step 6: Build the Ideas List

Standard format:

RankTickerCompanySectorIdea TypeThesisCatalystRiskConviction
{{RANK}}{{TICKER}}{{COMPANY_NAME}}{{SECTOR}}{{DIRECTION}}{{THESIS}}{{CATALYST}}{{RISK}}{{CONVICTION}}
Example600519贵州茅台白酒Long批价稳+动销旺+分红高Q1业绩超预期批价下行High
2........................

Conviction levels:

  • High: Strong thesis, clear catalyst, limited downside
  • Medium: Good thesis, catalyst timeline uncertain
  • Low: Exploratory, needs more research

Step 7: Monitor & Update

Ongoing tracking:

  • Weekly price and news updates
  • Catalyst tracking (china-catalyst-calendar)
  • Thesis validation / invalidation
  • Position sizing recommendations

Update triggers:

  • Earnings results
  • Material news (M&A, guidance, regulation)
  • Price moves >15% in a week
  • Thesis breaking or confirming

  • Screen criteria documented and reproducible
  • Each candidate has fundamental backing
  • Catalysts identified for each idea
  • Risk factors clearly stated
  • Conviction levels assigned
  • Liquidity verified (tradable)
  • Regulatory/compliance review passed

Data Source Mode Switch: Set env var IFIND_DATA_SOURCE_MODE to control data source preference.

  • ifind-only (strict): Use iFind only, error if unavailable
  • ifind-fallback (default): iFind preferred, fallback to AkShare
  • akshare-only, wind-only (Wind only), wind-fallback (Wind first, fallback to iFind → AkShare): Skip iFind, use AkShare only
