3/18/20251 min read
Introduction
Options traders often rely on the Greeks to measure risks and potential profitability. The Greeks help assess how option prices react to changes in stock price, volatility, time decay, and interest rates.
Key Greeks Explained
Delta (Δ)
Measures the rate of change in option price relative to stock price.
Call options have positive delta, while put options have negative delta.
Gamma (Γ)
Measures how fast delta changes as the stock price moves.
Higher gamma increases risk and reward potential.
Theta (Θ)
Measures the rate of time decay in an option’s value.
Options lose value as expiration approaches.
Vega (ν)
Measures an option’s sensitivity to changes in implied volatility.
High Vega options gain value with increased volatility.
Rho (ρ)
Measures sensitivity to interest rate changes.
Most relevant for long-term options.
Applying Greeks in Trading
Use Delta to gauge directional exposure.
Adjust positions based on Gamma to manage risk.
Monitor Theta when trading options close to expiration.
Trade high Vega options during earnings season.
Conclusion
Understanding Greeks improves decision-making and risk control, making them essential tools for profitable options trading.
