📊 Call & Put Options – Simple Explanation



Options are derivative contracts whose value is derived from an underlying asset such as:

  • Stocks
  • Indices
  • Commodities
  • Currencies

An option gives the buyer the right, but not the obligation, to buy or sell an asset at a predetermined price before a specific date.


Simple Definition of Options

An option is a contract that gives the buyer the right to buy or sell an asset at a fixed price before expiry.


Types of Options

There are two main types of options:

Call Option (CE)

Put Option (PE)


A Call Option gives the buyer the right to buy an asset at a predetermined price (Strike Price) before expiry.

Traders buy Call Options when they expect the market or stock price to rise.


Simple Definition of Call Option

A Call Option is purchased when you expect prices to move upward.


Suppose:

  • Stock Price = ₹1,000
  • Strike Price = ₹1,000
  • Premium = ₹20

You buy one Call Option.

If the stock rises to ₹1,100:

Profit:

1100−1000−20=801100-1000-20=801100−1000−20=80

Profit = ₹80 per share

The higher the stock rises above the strike price, the greater the profit potential.


Bullish Market View

You expect prices to rise.


Earnings Announcement

You anticipate strong company results.


Market Breakout

A stock breaks an important resistance level.


Limited Risk

Maximum loss is limited to the premium paid.


High Profit Potential

How a Put Option Works

Suppose:

  • Stock Price = ₹1,000
  • Strike Price = ₹1,000
  • Premium = ₹20

You buy one Put Option.

If the stock falls to ₹900:

Profit:

1000−900−20=801000-900-20=801000−900−20=80

Profit = ₹80 per share

The more the stock falls below the strike price, the greater the profit potential.

Premium depends on:

Intrinsic Value

Time Value

Leverage

Potential for larger percentage returns.

Example: Call Option Trade

If Nifty rises to 25,300:

Profit:

300−100=200300-100=200300−100=200

Net Profit = ₹200 per unit


Example: Put Option Trade
