PFE 25Δ put IV is 23% vs 25Δ call IV 25% — measuring downside protection cost.
Pfizer Inc. — 25Δ put/call IV ratio, 60-day trend, and earnings inflation
Pfizer Inc. (PFE) is a Healthcare stock with actively traded listed options. The 25-delta put IV reads 23.0% versus 25-delta call IV at 25.0%, a difference of -2.0pp. The chain is currently showing call skew (upside strikes priced richer), which describes how implied volatility distributes across strikes rather than where the underlying is heading. PFE strategy builder.
PFE shows inverted skew — 25Δ call IV (25.0%) prices 2.0pp above 25Δ put IV (23.0%); the model marks this as an unusual upside-demand regime.
Volatility skew measures how the options market prices downside protection (puts) compared to upside (calls). When 25-delta puts cost more than 25-delta calls, the market is paying a premium for hedging — a signal worth understanding before selling premium.
Skew is not a direction predictor. Steep skew can persist for months in calm markets, and flat skew can occur right before a crash. Combine with VRP and IV Rank for context.

Skew shows how much more the options market is paying for downside protection (puts) vs upside (calls). When 25Δ puts cost meaningfully more than 25Δ calls, hedging demand is elevated.
Steep put skew shifts the model to a higher tail-risk regime where naked positions carry more drawdown sensitivity than defined-risk structures.

Wave 1 uses static thresholds (1.05/1.15/1.30) — Wave 2 will calibrate per-ticker percentiles. Skew measures positioning and the cost of downside protection, NOT directional prediction. Steep skew can persist for months in calm markets, and flat skew can occur right before a crash.
Pfizer Inc.'s 25-delta put IV is 23.0% versus 25-delta call IV at 25.0%, a difference of -2.0pp. The chain is currently pricing call implied volatility above put implied volatility, which describes how implied volatility distributes across strikes rather than how the underlying is expected to move.
Skew sets the relative IV — and therefore the relative premium — across strikes. With Pfizer Inc.'s current skew regime, short-call premiums collect more, while call spreads cost more on the long-call side. The strategy comparison view shows how this changes the risk and credit profile of common structures across put-side, call-side, and combined wings.
Options skew measures how implied volatility distributes across strikes — specifically, whether 25-delta puts or 25-delta calls carry higher IV. It is a strike-axis observation about Pfizer Inc. options pricing, not a forecast of where the stock is heading. A persistent put skew often reflects steady demand for downside protection; balanced skew reflects symmetric demand for both wings. Skew is one input among several when comparing strike selection on the chain.
Pfizer Inc. is currently showing call skew — 25-delta call IV is above 25-delta put IV. The 25-delta put IV is 23.0% versus the 25-delta call IV at 25.0%, a difference of -2.0pp.

No — Pfizer Inc. is currently showing call skew on the chain (call IV 25.0% vs put IV 23.0%), so 25-delta calls are priced richer than 25-delta puts on an implied-volatility basis. This is less typical for equity options.
Call skew describes a chain configuration where 25-delta call IV is above 25-delta put IV. For Pfizer Inc., it means upside strikes are priced at richer implied volatility than downside strikes. Call skew is less common in equity options and can emerge around takeover speculation, supply squeezes, or asymmetric upside catalysts. Like put skew, it is a strike-axis pricing observation rather than a directional forecast.
Neither — skew describes the chain's pricing of relative downside vs upside IV, not the expected direction of the underlying. Pfizer Inc.'s skew can stay steep for months in calm markets or flatten right before a sharp move. Treat skew as positioning context for strike-level pricing, not as a price-direction signal.
Skew sets the relative IV across strikes, which translates into relative premium. With Pfizer Inc.'s current regime, short-call strikes collect richer premium, while call spreads carry a higher long-leg cost. The same dollar credit on different sides of the chain represents different risk profiles when skew is steep.
