Level 3: Derivatives & Options
1. What is an Option Contract?
An option is a derivative financial contract that gives the buyer the right, but not the obligation, to buy (Call Option) or sell (Put Option) an underlying asset (e.g., Nifty 50 Index or Reliance Industries) at a specified strike price before a predetermined expiry date.
2. The Two Primary Contract Types
- Call Option (CE – European Call): Gives the buyer the right to profit when the underlying market rallies upwards. You buy CE when you have a bullish view.
- Put Option (PE – European Put): Gives the buyer the right to profit when the underlying market falls downwards. You buy PE when you have a bearish view.
3. Strike Price & Moneyness (ITM, ATM, OTM)
| Moneyness | Call Option (CE) | Put Option (PE) | Analyst Recommendation |
|---|---|---|---|
| ITM (In-The-Money) | Strike < Spot Price | Strike > Spot Price | Best for Option Buyers (High Delta, Low Decay). |
| ATM (At-The-Money) | Strike ≈ Spot Price | Strike ≈ Spot Price | High liquidity; balanced risk-reward. |
| OTM (Out-of-The-Money) | Strike > Spot Price | Strike < Spot Price | Avoid! 95% expire worthless (Hero-to-Zero trap). |
4. The Option Premium Formula
Total Option Premium = Intrinsic Value + Extrinsic (Time) Value
- Intrinsic Value: Real tangible monetary value if exercised right now. Only ITM options contain intrinsic value.
- Extrinsic Value (Time Value): Speculative premium paid for the remaining time until expiry. OTM options contain 100% time value and zero intrinsic value!
