Secondary Sources

Workflow

Step 1: Identify What Changed

Change triggers:

• Quarterly earnings release (季报/年报)
• Management guidance update (管理层指引调整)
• Macro assumption change (rate, tax, policy)
• Model error or refinement
• M&A or restructuring event

Change log template:

Step 2: Update Historical Actuals

Quarterly actuals:

[Company] Q[X] 20XX Actuals (from AkShare / 巨潮):
- 营业收入: XXX亿 (YoY: +XX%)
- 毛利率: XX% (vs prior: XX%)
- 归母净利润: XXX亿 (YoY: +XX%)
- EPS: X.XX元
- 经营现金流: XXX亿

Update sequence:

1. Drop Q[X] actuals into historical columns
2. Verify sum checks (quarterly sum = annual)
3. Update LTM (Last Twelve Months) calculations
4. Check annual-to-quarter relationships

Step 3: Roll Forward Estimates

Revenue projections:

• Update growth rates based on Q[X] performance
• Consider:
• Order backlog changes
• New product ramp
• Market share gains/losses
• Capacity expansion

Margin projections:

• Update gross margin based on actual trend
• Update opex ratios based on actual leverage
• Flag structural changes (input costs, pricing power)

Balance sheet projections:

• Update working capital assumptions
• Update debt schedule if refinancing occurred
• Update CapEx plans

Step 4: Update Valuation

Market data refresh:

get_quote(ticker)  # Current price, PE, PB

Valuation metrics to update:

• Current stock price and change
• Trading multiple (PE, PB, EV/Sales, EV/EBITDA)
• 52-week range position
• Relative to sector median
• Implied growth vs historical

DCF updates (if applicable):

• Roll forward projections by one year
• Update market data inputs (beta, risk-free rate, shares)
• Update terminal growth if outlook changed

Step 5: Flag Material Changes

Change significance assessment:

Red flags to highlight:

• Revenue growth deceleration >500 bps
• Margin compression >300 bps
• Working capital deterioration
• Debt increase >20% vs prior forecast
• Management guidance lower than consensus

Step 6: Document Changes

Model update memo:

[公司名称]（[代码]）模型更新 [Date]

一、更新内容
   [Bullet list of changes made]

二、关键变动
   Revenue FY25E: [Old] → [New] ([Change]%)
   Net Income FY25E: [Old] → [New] ([Change]%)
   Driver: [Explanation]

三、估值影响
   新目标价: ¥XX.XX (之前 ¥XX.XX)
   调整幅度: +X% / -X%
   调整逻辑: [Brief rationale]

四、后续关注
   - [Next catalyst]
   - [Key metric to monitor]
   - [Risk factor]

Step 7: QC Checklist

China-Specific Update Considerations

Earnings Season Timing

Model update priority:

• Annual report: Complete overhaul of historicals
• Semi-annual: Major update, adjust full-year estimates
• Quarterly: Incremental update, verify full-year trajectory

业绩预告 Integration

If company issued 业绩预告:

• Use as directional signal before formal report
• Adjust estimates if variance >20% from prior
• Flag for detailed update when formal report arrives

Consensus Management

• Update consensus assumptions based on new information
• If company guidance differs from consensus, flag divergence
• Note if management commentary suggests estimate revision

Regulatory Changes

Monitor for:

• Tax rate changes (高新技术企业 reclassification)
• Accounting standard updates
• Industry-specific regulation impacts on assumptions
• Dividend policy changes (影响 DCF terminal value)

Quality Checks

Before delivering:

• [ ] All new actuals traceable to source
• [ ] Formulas verified (no hardcodes in calculations)
• [ ] Estimates logically consistent with new data
• [ ] Valuation update reflects current market conditions
• [ ] Changes documented in update memo
• [ ] Model passes basic QC (balance checks, sum checks)

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: Skip iFind, use AkShare only
