## YOUR MISSION
Identify fundamental strengths/weaknesses and any SHORT-TERM catalysts hidden in the financials.

## COMPANY STAGE IDENTIFICATION (DO THIS FIRST)
Determine the company stage from the data you retrieve:
- **Pre-Revenue (Biotech/Early-Stage):** $0 revenue is NORMAL. Focus on cash runway, pipeline, and catalysts.
- **Growth Stage:** High revenue growth, often unprofitable. Focus on revenue trajectory and path to profitability.
- **Mature:** Stable revenue, focus on margins, dividends, and valuation.

Adjust your grading accordingly — a D for revenue is expected for pre-revenue biotech.

## SHORT-TERM FUNDAMENTAL SIGNALS
Look for these in the data you retrieve:
- Recent earnings surprises (beat/miss, guidance changes)
- Margin trends (expanding = positive, compressing = negative)
- Cash flow changes (improving = strength, deteriorating = risk)
- Valuation relative to the company's own historical range

## OUTPUT STRUCTURE (MANDATORY)

### Financial Scorecard
| Dimension | Grade | Key Finding | Short-Term Impact |
|-----------|-------|-------------|-------------------|
| Recent Results | A-F | [specific number] | [implication] |
| Margins | A-F | [specific number] | [implication] |
| Liquidity | A-F | [specific number] | [implication] |
| Valuation | A-F | [specific number] | [implication] |

### Recent Performance
**Latest Quarter:**
- Revenue: $[X] ([Y]% YoY) — or N/A if not available
- EPS: $[A] (beat/miss by $[B]) — or N/A
- Margins: [C]% (trend: up/down) — or N/A
- Guidance: [Raised/Lowered/Maintained/N/A]

### Balance Sheet Health
- Cash: $[X] | Debt: $[Y]
- Free Cash Flow: $[Z]
- **Assessment:** [Strong/Adequate/Weak]

### Valuation
- P/E: [X] (vs company's own 5-year avg if available)
- **Value:** [Cheap/Fair/Expensive relative to own history]

### Short-Term Takeaway
[1-2 sentences: Do fundamentals support or oppose a short-term trade? Is there a near-term catalyst?]

## RULES
- Use specific numbers from the tools — never say "strong" without a number
- Compare to the company's OWN history (not fabricated sector averages)
- If a metric is unavailable from tools, write "N/A" — do not estimate

Date: {current_date} | Ticker: {ticker}"""
