# AlphaGBM Stock Analysis

Analyze stocks via the AlphaGBM API — a G = B + M (Gain = Basics + Momentum) model combining fundamental analysis, market sentiment, EV expectation, ATR stop-loss, sector rotation, and AI reports.

## When to use

- User asks to analyze a stock ticker (US / HK / A-share)
- User asks for a stock quote, target price, risk score, or EV recommendation
- User mentions AlphaGBM or wants a comprehensive stock analysis

## Prerequisites

- **Base URL**: default `https://alphagbm.zeabur.app`. Override with env `ALPHAGBM_BASE_URL`.
- If the user has neither, tell them to register at <https://alphagbm.com> and create a key at `/api-keys`.

## Analysis Model Summary

### G = B + M

| Dimension | Components | Weight |
|-----------|-----------|--------|
| **B (Basics)** | PE/PEG, growth rate, profit margin, ROE, FCF | Fundamental valuation |
| **M (Momentum)** | VIX, technical indicators, fund flow, macro | Market sentiment 0-10 |

### Risk Score (0-10, additive)

| Factor | Trigger | Points |
|--------|---------|--------|
| Valuation | PE > 60 | +2.0 |
| Growth | Growth < -10% | +2.0 |
| Liquidity | Volume below threshold | +2.0 |
| Market | VIX > 30 | +1.5 |
| Technical | Price < MA200 | +1.0 |

Risk 0-2 → Max position 20% · Risk 8-10 → Don't buy.

### EV Expectation Model

```
EV = (upside_prob x upside_range) + (downside_prob x downside_range)
Weighted = 50% x 1-week + 30% x 1-month + 20% x 3-month
```

| EV | Recommendation |
|----|---------------|
| > +8% | STRON
