Frequently Asked Questions
Delta signifies absolute directional exposure. If you hold a Call option with a Delta of 0.60, the option’s contract value will theoretically increase by $0.60 for every $1.00 increase in the underlying stock. Secondly, Delta is widely utilized as a proxy for probability, indicating roughly a 60% mathematical chance that the option will expire in-the-money.
Gamma measures the acceleration velocity of Delta. In the final hours leading up to an option’s expiration, the Gamma for at-the-money contracts spikes radically. This forces the Delta to oscillate from 0 to 1 violently, resulting in extreme, highly leveraged swings in portfolio equity that can either result in explosive gains or catastrophic wipeouts instantly.
Because options are contracts with a hard expiration date, they legally lose theoretical value every single day relative to time decay (Theta). Option buyers inherently fight actively against Theta, forced to secure a directional move fast enough to offset the daily financial drain. Contrastingly, option sellers fundamentally profit off Theta, mechanically collecting the decaying premium as time vanishes.
This is an iconic symptom of a catastrophic "IV Crush" driven by Vega dynamics. If you bought an extremely inflated option prior to a major earnings report, the subsequent collapse in systemic implied volatility drops the premium structurally faster than the Delta directional gains can compensate for, netting a horrific loss on a "winning" directional prediction.
The risk-free rate (usually pegged to government Treasury yields) structurally dictates the theoretical cost of carrying capital and discounting future payoffs in standard pricing models. While it typically possesses a highly muted impact on daily trading compared to Delta and Vega, significant shifts in macroeconomic Fed policy will actively distort long-term LEAPS option pricing structures.
