What happens if an Option Contract is Not Squared Off on Expiry?

• In-The-Money (ITM): The strike price of the option is advantageous for the holder, offering intrinsic value.
• Out-Of-The-Money (OTM): The strike price is unfavorable for the holder, leaving the option with no intrinsic value.
• At-The-Money (ATM): The strike price is approximately equal to the current market price of the underlying asset.

Stock Options

• ITM contracts are physically settled, meaning the buyer or seller must deliver or take delivery of the underlying stock, depending on the position.
• It is essential to understand the physical settlement process, as margins and additional charges may apply before expiry.

• These contracts expire worthless since their intrinsic value is zero.
• The buyer loses the premium paid, and no further obligations remain.

Index Options

If the Index Options Are Bought:

• These are automatically exercised on expiry.
• Profits or losses are settled in cash based on the difference between the strike price and the closing price of the index on the expiry day.
• Securities Transaction Tax (STT): Applicable at 0.125% of the intrinsic value for exercised contracts.
• Brokerage Charges: Charged on both sides — at purchase and settlement on expiry.

• These contracts expire worthless.
• The buyer loses the entire premium paid as there is no intrinsic value.
• Brokerage Charges: Only applicable at the time of purchase. No charges apply on expiry.

If the Index Options Are Shorted (Sold):

• Automatically exercised on expiry.
• Profits or losses are calculated based on the strike price, closing price, and the premium received.
• STT: Not applicable at expiry as it is charged only on the initial sell transaction.
• Brokerage Charges: Charged on both sides — when the options are sold and when they are settled on expiry.

• These expire worthless.
• The seller retains the entire premium received at the time of the transaction.
• Brokerage Charges: Only applicable when the options were sold. No additional charges apply at expiry.

Key Considerations for Traders:

1. Monitor Open Positions Closely: Ensure you are aware of the moneyness of your contracts as expiry approaches. 
2. Physical Settlement for Stock Options: Understand the margin requirements and delivery obligations for ITM stock options. 
3. Cash Settlement for Index Options: Keep track of cash flows associated with ITM index options, especially STT and brokerage charges. 
4. Plan Your Exit: Squaring off your positions before expiry can help avoid surprises, such as additional charges or settlement complexities.
