# AlphaGBM Earnings IV Panel

Everything you need for earnings week — historical IV crush + forward-looking implied
move + IV Rank strategy recommendation + a priced Iron Condor centered on the implied
move — in a single API call.

## What This Skill Does

| Concept | Description |
|---------|-------------|
| IV Crush | The sharp drop in implied volatility after an earnings announcement |
| Average Crush % | Mean IV decline from pre-earnings peak to post-earnings trough (last 8 quarters) |
| **Implied Move ±X%** | What options are pricing the earnings move to be, derived from ATM IV × √(DTE/365) |
| **IV Rank** | Current ATM IV percentile vs 20-day HV over 2y — drives strategy recommendation |
| **Strategy Recommendation** | IV Rank > 70 → short-IV plays (Iron Condor); < 30 → directional (Long Call/Put); 30-70 → wait |
| **Iron Condor Quote** | Ready-to-trade 4-leg spread with short strikes at ±1× implied move, concrete credit / max profit / max loss / breakevens |
| Historical comparison | How implied move compared to actual move across past 8 earnings |

## How to Use

**Input:** A ticker with upcoming or past earnings.

**Output:**
- Days to next earnings (if scheduled)
- Current stock price + ATM IV + IV Rank
- **Implied Move ±X% and ±$Y** — most quoted number during earnings season
- **Recommendation tag** (🔥 short IV / wait / directional) with zh/en copy
- **Iron Condor pricing** — 4 strikes + credit + max profit + max loss + breakeven bounds (Pro tier)
- Last 8 quarters: pre-earnings IV / post-earnings IV / crush % / actual move / straddle PnL
- Avg crush % and straddle win rate

**Example Queries:**
- `earnings crush AAPL` — Full crush history + next earnings IM
- `implied move NVDA` — What the options are pricing for next earnings
- `iron condor for META` — Priced-ready short-premium setup
- `IV rank MSFT earnings` — Strategy tag + recommendation
- `should I short premium before TSLA` — Recommendation + IC quote
- `straddle pnl AMZN last 8 quarters` — Historical short-premium win rate
