16. Do All Options Get Exercised?

No, not all options get exercised.
Only in-the-money (ITM) options — those that would result in a profit if exercised — are typically exercised, either manually or automatically by the exchange at expiry.

Options that are at the money (ATM) or out of the money (OTM) do not get exercised, as exercising them would lead to no benefit or even a loss. These contracts expire worthless.

What Does It Mean to "Exercise" an Option?

To exercise an option means to use the right that the option provides:

However, most options are not exercised manually. They are either closed before expiry (by selling or buying back the option), or, in the case of ITM options, automatically exercised by the exchange at expiry.

Scenarios at Expiry

Let’s understand the three types of option moneyness and what typically happens at expiry:

Moneyness TypeDefinitionWill It Be Exercised?Outcome
In the Money (ITM)The option has intrinsic valueYes (automatically)Settled in favor of holder
At the Money (ATM)Spot price equals strike priceNoExpires worthless
Out of the Money (OTM)The option has no intrinsic valueNoExpires worthless

Only in-the-money options are exercised.
All other options are simply allowed to lapse without any action from the trader.

What Happens to Options at Expiry in India?

In India, the NSE Clearing Corporation handles expiry settlements.

You don’t need to manually inform the exchange to exercise your ITM options — the system does it by default.

Example to Illustrate

Suppose you hold the following:

This option is in the money by ₹300.

Do Traders Always Wait for Exercise?

No. In reality, most traders do not hold options till expiry. Instead, they:

Especially in index options like Nifty and Bank Nifty, where physical delivery is not involved, most positions are exited before expiry for better control over profits and losses.

Why OTM and ATM Options Are Not Exercised

In both cases, they expire worthless, and the premium paid is lost.

Key Takeaways
  1. Not all options are exercised — only in-the-money options are exercised, typically automatically by the exchange at expiry
  2. Out-of-the-money and at-the-money options expire worthless because they provide no benefit if exercised
  3. Most traders exit their positions before expiry rather than hold them to exercise
  4. In India, options are cash-settled at expiry, and in-the-money options are settled based on the difference between strike and spot
  5. Understanding which options are likely to be exercised helps in managing positions, calculating risk, and planning margin requirements near expiry
