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

WAL 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 WAL Greeks charts?
Gamma, theta, and vega are largest for strikes near the Western Alliance Bancorporation 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 WAL's Greeks?
Western Alliance Bancorporation IV rank is 4, 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 28.0% to 150.4%. See the WAL implied volatility history for a longer view.
