Option Greeks measure how Direxion Daily Small Cap Bear 3x ETF (TZA) 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. TZA implied volatility is in the lower part of its one-year range, which keeps delta and gamma in a narrower range of strikes than usual.

How do I read the TZA Greeks charts?
Gamma, theta, and vega are largest for strikes near the TZA 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.
