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

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:

$Price×e−rT\text{Call Price} – \text{Put Price} = \text{Spot Price} – \text{Strike Price} \times e^{-rT}$

💡 Simplified Trick (for no-arbitrage condition):

If you hold:

1 Long Call
1 Short Put
You replicate a Forward Contract (same payoff).

$Strike=Put+Spot\text{Call} + \text{PV of Strike} = \text{Put} + \text{Spot}$

Where:

PV = Present Value
r = Risk-free rate
T = Time to maturity

🧠 Easy Memory Trick:

“Call + Bond = Put + Stock”
