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).

Gamma, theta, and vega are largest for strikes near the Oil States International 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.

Oil States International IV rank is 29, so implied volatility is in the lower part 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 24.2% to 209.0%. See the OIS implied volatility history for a longer view.

Across all open Oil States International options on Nov 4, 2026, net gamma exposure was $20.12K and net delta exposure was $431.89K per 1% move in the stock. The OIS gamma exposure chart shows where that gamma sits by strike.
