Options trading revolves around two key instruments: call options and put options. Understanding these is critical for profiting in bullish or bearish markets. This guide compares put vs. call options, explains their mechanics, and provides real-world examples.
What Is a Call Option?
A call option grants the buyer the right (but not obligation) to purchase an underlying asset at a predetermined strike price before expiration. Buyers pay a premium for this contract.
Example: BANKNIFTY Call Option
- Index: BANKNIFTY
- Expiry: 30 Jan
- Premium: ₹652.80
- Lot Size: 15
- Strike Price: 49,500

What Is a Put Option?
A put option allows the holder to sell an asset at the strike price. Sellers (writers) must buy the asset if the option is exercised.
Example: BANKNIFTY Put Option
- Index: BANKNIFTY
- Expiry: 30 Jan
- Premium: ₹444.00
- Lot Size: 15
- Strike Price: 49,000
Types of Strike Prices
Options are categorized by their strike price relative to the market price:
Call Options (CE):
- ITM (In-the-Money): Strike < Market Price (e.g., ₹19,800 CE @ ₹20,000 market).
- ATM (At-the-Money): Strike = Market Price (e.g., ₹20,000 CE).
- OTM (Out-of-the-Money): Strike > Market Price (e.g., ₹20,200 CE).
Put Options (PE):
- ITM: Strike > Market Price (e.g., ₹20,100 PE @ ₹20,000 market).
- ATM: Strike = Market Price (e.g., ₹20,000 PE).
- OTM: Strike < Market Price (e.g., ₹19,900 PE).
Key Terms in Options Trading
| Term | Definition |
|---|---|
| Intrinsic Value | Difference between asset price and strike price (applies only to ITM). |
| Time Value | Premium paid for potential future gains before expiration. |
| Theta Decay | Rate at which an option loses value as expiry approaches. |
Call Option Example
Scenario: NIFTY at ₹20,300; buy ₹20,200 CE (ITM) for ₹150 premium (lot size: 25).
NIFTY rises to ₹20,600:
- Profit: (₹20,600 - ₹20,200 - ₹150) × 25 = ₹6,250.
NIFTY stays flat:
- Loss: Entire premium (₹3,750).
Put Option Example
Scenario: NIFTY at ₹20,200; buy ₹20,300 PE (ITM) for ₹150 premium.
NIFTY falls to ₹20,000:
- Profit: (₹20,300 - ₹20,000 - ₹150) × 25 = ₹3,750.
NIFTY rises:
- Loss: Entire premium (₹3,750).

- Hedging: Protect stock holdings (e.g., buy puts to offset equity losses).
- High Volatility: Potential for rapid gains (e.g., ₹30 → ₹300 in a day).
