Analysis Methodology

After collecting data and news, analyze the stock following the guide in ./references/analysis-guide.md. Key points:

Scoring System (-5.00 to +5.00)

| Range | Signal | Typical Triggers | |-------|--------|-----------------| | +/-4.0 to +/-5.0 | Strong | Major breakout, significant policy change, critical news | | +/-2.0 to +/-3.9 | Moderate | Policy tailwind, sector rotation, fundamental shift | | +/-0.5 to +/-1.9 | Weak | Sentiment shift, valuation deviation, volume change | | 0.0 to +/-0.4 | Neutral | Insufficient info or no clear direction |

Multi-dimensional Analysis

Always consider ALL dimensions — do not rely on just one:

Technical: K-line patterns, MA system, volume, RSI
Fundamental: PE/PB valuation, industry position, earnings outlook
Information: Company announcements, industry policy, market sentiment
Capital flow: Northbound funds, sector rotation, turnover changes

When dimensions contradict each other (e.g., bullish volume but overvalued), explicitly state the conflict.

Report Format

Present analysis as:

## {Stock Name} ({Stock Code}) Analysis Report
Date: {YYYY-MM-DD}

**Score: {score}** ({signal level})

Special Cases

Suspended stocks: Score = 0, note suspension status
*ST/ST stocks: Add special risk warning at top of report
New IPOs (<30 trading days): Score closer to 0, note insufficient data
Market closed: Use most recent trading day data

Common Pitfalls

Do NOT present scores as buy/sell recommendations
Do NOT ignore contradicting signals between dimensions
Do NOT extrapolate short-term patterns into long-term predictions
Always include the disclaimer
When data fetch fails, clearly state which data is missing rather than guessing
