Introduction
In the realm of financial markets, options occupy a unique space, granting traders the right but not the obligation to buy or sell an asset at a predetermined price on a specific date. This date, known as the option’s expiry date, marks the moment when the option contract ceases to exist and the holder’s rights expire. Understanding the significance of option trading expiry is crucial for both novice and experienced traders alike.

Basic Concepts
An option contract is essentially a bet on the future price of an underlying asset. Call options grant the holder the right to buy the asset at a set price (strike price) by the expiry date, while put options confer the right to sell at the strike price. The difference between the market price of the asset and the strike price, combined with the premium paid upfront, determines the potential profit or loss.
Time Decay
As the option approaches its expiry date, a phenomenon known as time decay comes into play. Time decay erodes the option’s value since the intrinsic value, which represents the potential gap between the strike price and the market price, diminishes as time passes. This is because the probability of the option being in-the-money decreases as the expiry date draws nearer.
Settlement and Exercise
On the expiry date, there are three main scenarios: the option is in-the-money, out-of-the-money, or at-the-money. If the option is in-the-money, the holder is likely to exercise their right to buy (if it’s a call option) or sell (if it’s a put option) the asset. In this case, the settlement occurs via the delivery of the asset.
If the option is out-of-the-money, it expires worthless, and the premium paid for the contract is lost. At-the-money options may offer a partial exercise if the price of the underlying asset is equal to the strike price.

Trading Strategies
Option expiry dates present numerous trading opportunities. Traders may employ certain strategies to manage risk and maximize potential returns. One strategy is selling options near expiry, often known as “selling premium.” By selling options with high time decay, traders aim to collect the premium upfront knowing that the option has a high probability of expiring worthless.
Another strategy is rolling over options. This involves selling the expiring option and buying a new option with a later expiry date. By doing so, traders extend the time value of their option position while adjusting their risk and profit potential.
