Near-settlement moves, shown with context.
Contracts with fewer than 2 full days to expiry remain in the tables but are excluded from headline rankings. Settlement proximity, time decay, changing liquidity and fewer quotes can exaggerate their changes.

Where normalized model Greek intensity is highest.
These are comparable Black-forward Greeks for a one-SOL ATM-forward call at each listed expiry—not portfolio exposure, open interest or a prediction of dealer positioning.
SOL 30-day implied volatility was 3.3 times VIX, while its 30-session return correlation with SPX was low at 0.25.
Implied-volatility premium
SOL 30-day ATM IV was 52.36%, against VIX at 15.72: a 36.64-point spread and 3.33× ratio.
Realised-volatility regime
SOL 20-calendar-day realised volatility was 74.10%, versus SPX 20-session realised volatility of 8.54%. The spread ranked at 52.9 percentile of 223 prior observations.

Fixed tenors
Fixed-tenor measures are published only when listed expiries bracket the target at both comparison snapshots. Targets outside either observable range are suppressed, not extrapolated; headline rankings use only supported tenors.
Smile reconstruction
Listed-expiry smiles are reconstructed from stored SVI total-variance parameters on a fixed log-moneyness grid.
Ultra-short expiries
Expiries with fewer than 2 full days remaining stay in detailed tables but are excluded from headline rankings. Settlement proximity, time decay, changing liquidity and fewer quotes can exaggerate their changes.
