In-the-Money

In-the-money options are the most straightforward to analyse because their premium includes a concrete, measurable component — intrinsic value — in addition to time value. A Nifty 17,800 call option was in-the-money when Nifty traded above 17,800. The depth of in-the-money-ness depended on how far above the strike the underlying was trading.

Deep in-the-money options have a delta close to 1 for calls or -1 for puts, meaning they move almost in lockstep with the underlying. This makes them function like leveraged positions in the underlying itself, with a lower capital outlay than purchasing the equivalent notional value of shares or futures. However, the premium for deep ITM options is significant because of the intrinsic value embedded in them.

Liquidity is an important consideration for ITM options on NSE. While at-the-money options tend to have the tightest bid-ask spreads and the highest open interest, deep in-the-money options can be relatively illiquid, resulting in wider spreads. Participants attempting to exit large ITM positions in Nifty or Bank Nifty found that impact cost could erode a portion of the theoretical profit, particularly in fast-moving markets.

A nuance often overlooked is that ITM options do not automatically result in profits for the buyer. The profitability depends on whether the premium paid was less than the intrinsic value at exit or expiry. If a participant paid a large premium for a call that was modestly in-the-money at expiry, the net result could still be a loss if the premium exceeded the intrinsic value realised.

For option writers, in-the-money options represent risk. A call writer who sold an option that moved into the money faces mark-to-market losses as the option's delta increases and the intrinsic value grows. Managing or hedging this directional risk is a central concern for professional options desks.
