Buying deep out-of-the-money (OTM) options for ₹20 hoping for a 5x return is the quickest way retail traders destroy trading capital. To survive in options trading, you must master Greeks.
1. Delta (Δ): Directional Sensitivity
Delta tells you how much the option premium moves for every 1-point change in the underlying index or stock. At-The-Money (ATM) options have a Delta around 0.50, meaning if Nifty moves 100 points, the ATM call will gain approximately 50 points.
2. Theta (θ): The Silent Wealth Destroyer
Theta measures the daily rate of decline in option premium due to the passage of time. As expiration nears, Theta decay accelerates exponentially. If you are an option buyer holding trades overnight without sharp momentum, Theta eats into your profits daily.
Expiry Day Zero-Hero Trap:
On weekly expiry days, Theta decay is at maximum velocity. OTM premiums collapse towards zero unless the underlying price moves with extreme velocity (Gamma explosion).
3. Gamma (Γ): The Rate of Delta Change
Gamma represents the rate of change of Delta. During high volatility momentum moves, Gamma accelerates Delta from 0.30 to 0.80 rapidly, which creates explosive multi-bagger moves on expiry afternoons for educated option buyers.
