Greeks Explained
- Delta (Δ): How much the option price changes for a $1 move in the stock. Ranges from -1 to 1 for individual options.
- Gamma (Γ): How much delta changes for a $1 move in the stock. Higher gamma means delta is more sensitive.
- Theta (Θ): How much value the option loses per day due to time decay. Usually negative for long positions.
- Vega (ν): How much the option price changes for a 1% change in implied volatility. Long options benefit from increasing volatility.
