# AlphaGBM Tepper Panic-Buy Signal

David Tepper made two historic panic-bottom calls: March 2009 ("I'm betting on
the Fed") and March 2020 (COVID bottom). Both had identical fingerprints: VIX
spiked > 40, multi-indicator fear was maxed, and Tepper loaded quality large-caps
(banks 2009, SPY/QQQ 2020).

This skill mechanizes that fingerprint.

## The Signal Logic

Three gates must all pass for the signal to arm:

1. **VIX ≥ 35** — extreme fear, not just elevated
2. **FearScore ≥ 80** — multi-indicator panic (reuses existing FearScore module:
   VIX + IV Rank + RSI + Volume + Put/Call + Consec-Down-Days)
3. **Quality filter** — market cap > $50B AND profit margin > 0 (no memes,
   concept stocks, or pre-revenue small caps)

When all three pass → `signal: true`, level: `armed`.

## Signal Levels

| Level | Condition | Prescription |
|-------|-----------|--------------|
| `armed` | VIX ≥ 35 AND Fear ≥ 80 | 🔥 Historic-level buying moment — scale into SPY/QQQ/DIA |
| `watch` | VIX ≥ 30 OR Fear ≥ 70 | ⚡ Approaching — prepare capital, don't act yet |
| `near` | VIX ≥ 25 OR Fear ≥ 60 | Lukewarm — far from Tepper-level panic |
| `cold` | below | Calm — **the patience state**, which is most of the time |

**Tepper's own framework includes "do nothing" as a first-class state.** Most
calls to this endpoint will return `cold` — that's by design. The value isn't
in the signal firing often, it's in *never missing* a VIX > 40 event.

## Why This Is a Separate Skill

`alphagbm-fear-score` gives the raw panic index. `alphagbm-vix-status` gives
the VIX tier. This skill combines them with Tepper's specific criteria
(quality filter + threshold rules) to produce a single yes/no decision.

## How to Use

**Input:**
- `ticker` (optional, default `SPY`) — the quality-filter applies to this ticker

**Output:**
- `vix`, `fear_score` — the two input signals
- `vix_pass`, `fear_pass`, `quality_pass` — per-gate booleans
- `signal` — final boolean
- `level` — `armed / watch / near / cold`
- `recommended_etfs` — `["SPY", "QQQ", "DIA"]` (quality large-cap universe)
- `advice_zh`, `advice_en` — natural-language prescription

## Example Queries

- `is this a Tepper buy signal` → call with default SPY
- `panic-buy check on QQQ` → substitute QQQ
- `should I buy the panic now` → returns `cold` if calm → "wait, this is the patience state"
- `am I missing a historic bottom` → the only time this fires, the answer is "yes, don't miss it"
- `Tepper-style entry for DIA` → quality large-cap → passes quality filter

## Mock Data

Mock data in `mock-data/tepper-signal/` — samples for `armed` (VIX 42, Fear 85) and `cold` (VIX 17, Fear 35).
