BXSL 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 BXSL Greeks charts?
Gamma, theta, and vega are largest for strikes near the BXSL 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 BXSL's Greeks?
BXSL IV rank is 9, 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 7.8% to 155.7%. See the BXSL implied volatility history for a longer view.
How much gamma and delta do BXSL options carry in total?
Across all open BXSL options on Nov 9, 2026, net gamma exposure was -$14.69K and net delta exposure was -$9.89M per 1% move in the stock. The BXSL gamma exposure chart shows where that gamma sits by strike.
