# longbridge-tech-hype

Tech hype versus fundamentals — detect valuation bubbles and identify which theme-driven rallies have fundamental backing.

> **Response language**: match the user's input language — Simplified Chinese / Traditional Chinese / English.

## When to use

Trigger on prompts asking for:

- Bubble or hype detection — *"这只 AI 概念股是不是泡沫"*, *"AI bubble check"*, *"估值泡沫"*
- Theme vs. fundamentals — *"主题炒作还是有基本面"*, *"hype vs fundamentals"*, *"narrative vs reality"*
- Tech sector valuation check — *"科技股估值贵不贵"*, *"半导体概念股"*, *"新能源估值"*

For pure valuation percentile defer to `longbridge-valuation`. For sector-wide ranking defer to `longbridge-constituent`.

## Workflow

1. Extract and normalise the symbol(s).
2. Fetch in parallel:
   - Valuation multiples and historical percentile (PE, PS, EV/EBITDA)
   - Industry median valuation for peer context
   - Last 2–3 years income statement (revenue growth, net income growth, gross margin trend)
   - Recent news and narrative themes
3. Compute the **Hype Score**:
   - Valuation percentile (0–100) vs. revenue growth rate
   - Gap = `valuation_percentile − revenue_growth_rank` (positive = hype-heavy)
4. Classify the stock:
   - `Fundamentally Justified` — growth supports valuation
   - `Partially Justified` — moderate gap, watch closely
   - `Hype-Driven` — large gap, sentiment outpacing fundamentals
   - `Detached Bubble` — extreme valuation with decelerating growth
5. Summarise key narrative themes from news and flag whether each has financial backing.

> If unsure of exact flag names, run `longbridge <subcommand> --help` before proceeding.

## CLI

```bash
# Valuation multiples and historical percentile
longbridge valuation <SYMBOL> --format json

# Industry median valuation
longbridge industry-valuation <SYMBOL> --format json

# Income statement — revenue, net income, margins
longbridge financial-report <SYMBOL> --kind IS --format json

# Recent news — theme keywords
longbridge news <SYMBOL> --format json
```

## Output structure

```
TECH HYPE ANALYSIS — <SYMBOL>  <Date>

VERDICT: [Fundamentally Justified | Partially Justified | Hype-Driven | Detached Bubble]
Hype Score: xx/100  (higher = more hype-heavy)

VALUATION SNAPSHOT
PE:  xx.x×  (xx-th percentile, 3Y)   Industry median: xx.x×
PS:  x.x×   (xx-th percentile, 3Y)
EV/EBITDA: xx.x×  (xx-th percentile, 3Y)

FUNDAMENTAL CHECK
Revenue Growth (YoY):  +xx%  →  +xx%  →  +xx%
Net Income Growth:     +xx%  →  +xx%  →  +xx%
Gross Margin:          xx%   →  xx%   →  xx%

NARRATIVE THEMES (from news)
Theme               Has Backing?   Evidence
AI / LLM            ✓ Partial      Revenue up xx%, but margin flat
Semiconductor cycle ✗ No data      Mostly sentiment-driven
...

CONCLUSION
<2–3 sentence synthesis of hype vs. fundamental alignment>
