| Expiration | IV | Expected move | 1 SD range | Straddle |
|---|---|---|---|---|
| Oct 2, 20264 days | 67.7% | ±$14.14 (7.1%) | $185.25 to $213.53 | $11.30 |

Each expiration has its own implied volatility, and short-dated IV reacts more to near-term events, so the nearest expiration can differ a lot from the 30-day figure.
