Option Greeks measure how McKesson Corporation (MCK) 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. MCK implied volatility is near the bottom of its one-year range, which keeps delta and gamma in a narrower range of strikes than usual.

MCK 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 MCK Greeks charts?
Gamma, theta, and vega are largest for strikes near the McKesson 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 MCK's Greeks?
McKesson IV rank is 16, 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 20.5% to 131.9%. See the MCK implied volatility history for a longer view.
