SPHR skew by horizon

As of Nov 11, 2:43 PM ET

Implied volatility by strike as a percent of spot, interpolated between 6 listed expiries. Skew is the 90% strike minus the 110% strike, in volatility points. A dash means no quoted option covers that point.

Horizon	90% strike	95%	At the money	105%	110% strike	Skew
7 days	-	-	-	-	-	-
30 days	59.6%	57.1%	55.3%	54.2%	54.5%	+5.1
90 days	58.0%	56.8%	55.2%	54.0%	53.3%	+4.7

At 30 days, the 90% strike trades at 59.6% implied volatility and the 110% strike at 54.5%: puts are priced 5.1 volatility points above calls. That put-over-call gap is wider than 55% of the 1,449 tickers we cover.

IV Term Structure

ATM implied volatility across expirations. Contango (rising) is normal; backwardation (inverted) signals a near-term event.

Understanding Options Skew

Options skew measures the difference in implied volatility between out-of-the-money puts and equidistant calls. The 25-delta skew compares the IV of a 25-delta put to a 25-delta call.

Steep skew: The market is pricing in higher demand for downside protection. This is typical of equity indices and individual stocks with tail risk.

Flat or inverted skew: Can indicate squeeze positioning, bullish sentiment, or heavy call buying driving up upside IV.

Term Structure Regimes

Contango (normal): Longer-dated options have higher IV than shorter-dated. Reflects time-value premium and normal uncertainty growth.
Backwardation (inverted): Near-term IV exceeds far-term. Signals an imminent catalyst: earnings, FOMC, FDA decision, or other binary event.
Flat: Uniform IV across the curve. Can indicate low conviction or a transition between regimes.
