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 Charles Schwab 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.

Charles Schwab IV rank is 34, 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 20.2% to 38.0%. See the SCHW implied volatility history for a longer view.

Across all open Charles Schwab options on Nov 4, 2026, net gamma exposure was -$2.42M and net delta exposure was -$42.31M per 1% move in the stock. The SCHW gamma exposure chart shows where that gamma sits by strike.

Charles Schwab is one of the largest retail-oriented financial-services companies in the US, with $11.9 trillion in client assets across its brokerage, banking, asset management, custody, financial advisory, and wealth management businesses at the end of 2025.
