Option Greeks measure how Corning Incorporated (GLW) option prices respond to changes in the stock price (delta and gamma), the passage of time (theta), implied volatility (vega), and interest rates (rho). These charts plot each Greek by strike, so you can see where an expiration's price risk, time decay, and volatility exposure are concentrated. GLW implied volatility is near the middle of its one-year range, so delta and gamma cover about their usual range of strikes.

GLW Option Greeks FAQ
What are option Greeks?
Option Greeks measure how an option's price responds to changes in the stock price (delta and gamma), time (theta), implied volatility (vega), and interest rates (rho).
How do I read the GLW Greeks charts?
Gamma, theta, and vega are largest for strikes near the Corning stock price and shrink for strikes far above or below it. Theta grows as expiration gets closer, while vega is larger for expirations further out. Call delta runs from 0 to 1 and put delta from -1 to 0, near 0.50 and -0.50 at the money, and roughly estimates the chance that an option finishes in the money.
How does implied volatility affect GLW's Greeks?
Corning IV rank is 43, so implied volatility is near the middle of its one-year range. Higher implied volatility raises option premiums and daily time decay (theta), and spreads delta and gamma across a wider range of strikes. Over the past year, 30-day implied volatility ranged from 31.5% to 98.4%. See the GLW implied volatility history for a longer view.
How much gamma and delta do GLW options carry in total?
Across all open Corning options on Nov 4, 2026, net gamma exposure was -$24.09M and net delta exposure was -$925.66M per 1% move in the stock. The GLW gamma exposure chart shows where that gamma sits by strike.
