How to Calculate the Time Value of an Option

The “time worth” of an choice is the extrinsic worth of an choice.

The time period “time worth” is an off-the-cuff method of claiming the extra correct title of “extrinsic worth.”

Whereas it’s true that “time worth” is predicated on how a lot time is left until expiration.

It isn’t simply “time”.

Earlier than explaining what which means, let’s begin with the fundamentals.

There are two forms of choices contracts: put choices and name choices.

The worth of an choice is what an investor or a dealer is prepared to pay for that choice.

The worth of an choice is additional subdivided into intrinsic worth and extrinsic worth.

Some choices have intrinsic and extrinsic values, whose sum is the choice’s worth.

Some choices haven’t any intrinsic worth and solely have extrinsic worth.

Usually (however not all the time), the extrinsic worth of an choice decreases as the choice will get nearer to expiration.

At expiration, the extrinsic worth will all the time be zero.

If an choice has intrinsic worth left at expiration, that worth is routinely transformed into actual money or inventory, after which the choice disappears.

If a put choice has intrinsic worth at expiration, the holder can train it (most brokers will routinely train it for you).

That implies that the inventory you personal will probably be offered on the choice’s strike worth.

In case you don’t personal any such inventory, then you’re going to get money as in the event you bought the inventory at market worth after which offered it at strike worth.

If a put choice has intrinsic worth, this will probably be to your profit, and you’re going to get cashback.

It is because a put choice can solely have intrinsic worth if its strike worth is above the underlying inventory’s market worth.

This situation is when the choice is “in-the-money”.

Equally, a name choice has intrinsic worth if the underlying inventory’s worth is larger than the strike worth.

The proprietor of a name choice with intrinsic worth at expiration will train (or the dealer will routinely train) that choice to purchase the inventory on the strike worth.

This advantages the proprietor as a result of they purchase inventory at a decrease market worth.

Then, that in-the-money name choice is transformed into inventory, and the choice disappears.

If the proprietor now not desires this inventory, he can then instantly promote that inventory at market worth if she or he needs to take action.

It’s all the time vital that computerized train (in each circumstances) is financially useful to the proprietor of the choice that’s being exercised.

The intrinsic worth is calculated because the distinction between the underlying inventory’s worth and the strike worth.

You may consider intrinsic worth because the “actual tangible worth” of an choice.

Within the case of the put choice

Intrinsic worth of put choice = strike worth of put choice – market worth of the inventory

Okay, not sufficient info.

Additional, assume that this put choice has 27 days until expiration and the put choice is buying and selling at $7.90 (on a per-share foundation).

The time worth is calculated the identical method.

I hope I didn’t make this text sound too sophisticated.

Possibly I may have merely mentioned:

Time worth = extrinsic worth

Extrinsic worth = choice worth – intrinsic worth

Within the case of “out-of-the-money” choices, they haven’t any intrinsic worth, so…

Extrinsic worth = choice worth.
