PFE put/call ratio

The put/call ratio for the 2026-Oct-16 expiry is 0.25: well under 1, so traders hold noticeably more calls than puts on that date. Readings well below 0.7 are often read as complacent and above 1.2 as fearful, and extremes are sometimes taken as contrarian signals, but on index products like SPY a high ratio is normal because puts are bought as insurance. It is a sentiment gauge, not a direction call. What the ratio measures and what it does not, or compare it with every tracked stock's put/call ratio today.

Reading the PFE expected move table

Each row is one expiry. The shaded band is the one-standard-deviation range the option chain implies for PFE on that date: the market gives roughly a two-in-three chance that PFE closes inside it and a one-in-three chance it closes outside. The black tick is the last traded price, 28.37. The diamond is max pain, the strike where option holders would collect the least if the stock settled there.

The range widens with time because uncertainty compounds with the square root of time: the 2026-Nov-13 range (±7.32%) is wider than the 2026-Oct-16 range (±2.41%) even though the daily volatility behind both is the same.
