Options Trading Basics: Call & Put Options
Options trading involves Call Options and Put Options, which allow traders to bet on the rise or fall of an asset.
1. What is a Call Option?
A Call Option gives the buyer the right (but not the obligation) to buy an asset at a fixed price before expiry.
- Bullish View – You buy a Call when you expect the price to rise.
- Profit Formula = (Market Price – Strike Price – Premium Paid)
- Risk – Limited to the premium paid.
- Unlimited Profit Potential
Example:
- Stock: Reliance (₹2500)
- Buy Call Option (₹2600 Strike) at ₹20
- If Reliance goes to ₹2700, your profit = ₹80 per share
2. What is a Put Option?
A Put Option gives the buyer the right to sell an asset at a fixed price before expiry.
- Bearish View – You buy a Put when you expect the price to fall.
- Profit Formula = (Strike Price – Market Price – Premium Paid)
- Risk – Limited to the premium paid.
- Unlimited Profit if Price Falls Sharply
Example:
- Stock: TCS (₹3400)
- Buy Put Option (₹3300 Strike) at ₹30
- If TCS falls to ₹3200, your profit = ₹70 per share
3. Put-Call Parity (Trick for Understanding Relationship)
Put-Call Parity is a concept that helps in arbitrage trading and pricing options correctly.
Formula:
Call Price – Put Price = Spot Price – Strike Price + Risk-Free Interest
OR
Call Option + Cash = Put Option + Stock
This means:
- If Call is expensive, Put is cheap → Buy Put, Sell Call.
- If Put is expensive, Call is cheap → Buy Call, Sell Put.
Put-Call Parity Arbitrage Trick:
- If an option misprices, traders use this formula to make risk-free profits.
- Works best in low volatility markets.
4. Simple Trick to Trade Using Put-Call Parity
If Call is expensive → Sell Call & Buy Put of the same strike.
If Put is expensive → Sell Put & Buy Call of the same strike.
This helps in identifying mispriced options and making quick profits using arbitrage strategies.

Here’s a clear breakdown of Call Option, Put Option, and the Put-Call Parity Trick, simplified for easy understanding:
1. What is a Call Option?
A Call Option gives the buyer the right (but not the obligation) to buy an asset (e.g., stock) at a fixed price (called the strike price) before a certain date.
You buy a Call when:
You think the price will go up.
2. What is a Put Option?
A Put Option gives the buyer the right (but not the obligation) to sell an asset at a fixed strike price before a certain date.
You buy a Put when:
You think the price will go down.
3. Put-Call Parity – Formula & Trick
Put-Call Parity connects the price of calls and puts on the same stock, with the same strike and expiry.
Formula:
Call Price−Put Price=Spot Price−Strike Price×e−rT\text{Call Price} – \text{Put Price} = \text{Spot Price} – \text{Strike Price} \times e^{-rT}
Simplified Trick (for no-arbitrage condition):
If you hold:
-
1 Long Call
-
1 Short Put
You replicate a Forward Contract (same payoff).
OR
Call+PV of Strike=Put+Spot\text{Call} + \text{PV of Strike} = \text{Put} + \text{Spot}
Where:
-
PV = Present Value
-
r = Risk-free rate
-
T = Time to maturity
Easy Memory Trick:
“Call + Bond = Put + Stock”
This means:
-
If you buy a Call and a bond (which pays the strike), it gives the same return as buying a Put and the stock.
Use in Trading:
Put-Call Parity helps you:
-
Spot arbitrage opportunities
-
Check if options are overpriced or underpriced
-
Build synthetic positions (e.g., synthetic long stock)
