Lesson
The Greeks - Delta and Theta

Back to the knowledge tree again I see.

Welcome,

New subscribers and day 1ā€™ers thank you for stopping by.

As you may know, we are continuing our option series (not sure how long it will last, certainly has lasted longer than me in Vegas).

Today we are looking at the Greeks. I only want to start with two of the Greeks - Delta and Theta.

Delta āˆ† ā€œcompares the change in price of the underlying security to the change in price of the optionā€

ā€œYou lost me šŸ˜•ā€ - nah, stay with me. So we know that options give you the right to buy or sell a stock at a certain price (ā€œstrike priceā€). Well, if the stock price is going up and up and you have the right to buy at a locked in price, that makes your option contract more valuable. Say you looked at one of your Amazon call options on Robinhood and the Delta āˆ† is 0.4 this means - for every $1 that Amazon goes up, your option contract goes up 40 cents. Opposite is also true for a put. If your Amazon putā€™s Delta āˆ†  is -0.4, then you lose 40 cents for each dollar Amazon goes up.

Boom - thatā€™s Delta (well, the gist of it). Good shitšŸ¤Œ

Theta Ļ“ ā€œmeasures the value of the option relative to how much time is leftā€

So we know there is an expiration date on option contracts. Imagine you make a $20 bet with your buddy that a football team wonā€™t score at all during the game. If the team hasnā€™t scored at all and there is 1 minute left, that bet becomes really valuable to you and worthless to him. This is because there is less of a chance for something to happen with only 1 minute left. The same is true with options, as you move closer to the expiration date, the value decreases because of the lower likelihood of something happening before it expires. šŸ¤” *Theta is also called ā€œTime Decayā€

A Theta Ļ“ of -0.06 (negative for the buyer of an option) means the option loses 6 cents every day. This value can change, and as you can imagine, it starts really chunking as it gets towards expiring.

But hey, thatā€™s the scoop of Theta. Not so bad.

Summary:

  • Delta measures the change in option value due to the change in stock price.

  • Theta measures the ā€œdecayā€ of option value over time.

Thank you
Thatā€™s All Folks

Hey, thanks for getting down to here. I hope you learned something new and can now (ideally) use some of this in your own investing. If you want to see some other topics, use the comment part of the rating scale below (pick a rating then you will be prompted). Yes, I read each of them by the way. Halfway through the week, keep chugging along champ.

Cheers,
