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)
