Options Contract Types

1.     Call Option (CE)

Call Option gives the buyer the right, but not the obligation, to purchase the underlying asset at a specified strike price within a certain time period. Buyers of call options expect that the price of the underlying asset will rise above the strike price before the option expires, allowing them to profit from the difference.

  • Call Option: Contract giving right to buy the underlying asset at strike price.
  • Buyer of Call: Expects market price to rise above strike price.
  • Seller of Call: Obligated to sell underlying asset if buyer exercises option.
  • Profit Potential: For buyers, profit is unlimited as prices rise indefinitely; loss limited to premium paid.
  • Risk for Seller: Sellers (writers) of calls face unlimited risk if prices rise sharply.

Example: Buys NIFTY 18000 Call at ₹100; NIFTY rises to 18500 → profit = ₹400.

2.     Put Option (PE)

Put Option gives the buyer the right, but not the obligation, to sell the underlying asset at a specified strike price within a certain time period. Buyers of put options expect that the price of the underlying asset will fall below the strike price before the option expires, allowing them to profit from the decline.

  • Put Option: Contract giving right to sell underlying asset at strike price.
  • Buyer of Put: Expects market price to fall below strike price.
  • Seller of Put: Obligated to buy underlying asset if buyer exercises option.
  • Profit Potential: For buyers, profit increases as prices fall; loss limited to premium paid.
  • Risk for Seller: Sellers (writers) of puts face large risk if prices fall sharply.

Example: Buys NIFTY 18000 Put at ₹120; NIFTY falls to 17500 → profit = ₹380.

3.     What is CE and PE?
Symbol Stands For Meaning
CE Call European Right to Buy at expiry (European style)
PE Put European Right to Sell at expiry (European style)

 

  • CE means you have bought the right to buy the asset on the expiry date.
  • PE means you have bought the right to sell the asset on the expiry date.

The “E” in CE/PE stands for European Style, which indicates that the option can only be exercised on the expiry date, not before.

🔹 European Style Options

A European option can be exercised only on the expiration date, not before. This style simplifies pricing and risk management, and is standard in Indian markets (e.g., NIFTY, BANKNIFTY, RELIANCE options).

🔹 American Style Options

An American option can be exercised at any time up to and including expiry. This added flexibility gives more strategic choices but makes pricing more complex. Commonly used in the US equity markets.
