Options 102: Moneyness & Valuation

The Three States of Moneyness

The relationship between the Stock Price and the Strike Price determines the "Moneyness" of an option:

1. In-the-Money (ITM): The option has real, tangible value. (e.g., A $45 Call when stock is at $50).

2. Out-of-the-Money (OTM): The option has NO real value yet. It is purely speculative. (e.g., A $55 Call when stock is at $50).

3. At-the-Money (ATM): The Strike Price equals the Stock Price.

The Valuation Formula

An option's total price (Premium) is the sum of two parts:

Premium = Intrinsic Value + Time Value Premium

Intrinsic Value: The profit you would make if you exercised the option right now. For a Call, it is `Stock Price - Strike Price`. If the result is negative, Intrinsic Value is zero.

Time Value: The extra amount buyers pay for the possibility that the stock will move further in their favor before expiration.

The Wasting Asset

Intrinsic Value fluctuates with the stock price. But Time Value behaves differently.

Time Value is strictly a "wasting" asset. As time passes, the probability of a big move decreases. Therefore, the Time Value component shrinks every day, eventually reaching zero at expiration.

At expiration, an option is worth ONLY its Intrinsic Value.

How to read the chart below:

1. Blue Line (Total Value): This is the price you see in the market.

2. Green Line (Intrinsic Value): This is the floor value of the option. It can never be negative.

3. The Gap (Time Value): The distance between the Blue and Green lines represents the "Premium" you pay for potential future movement. Notice how this gap is widest when the stock is At-The-Money.
