KMX 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 KMX Greeks charts?
Gamma, theta, and vega are largest for strikes near the CarMax 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 KMX's Greeks?
CarMax IV rank is 14, so implied volatility is near the bottom 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 36.5% to 179.2%. See the KMX implied volatility history for a longer view.
How much gamma and delta do KMX options carry in total?
Across all open CarMax options on Nov 11, 2026, net gamma exposure was $670.69K and net delta exposure was $67.16M per 1% move in the stock. The KMX gamma exposure chart shows where that gamma sits by strike.
