Stock options lose value over time and that can be used in your favor by reversing the logic. I’ll show you how to put the odds in your favor by reversing the logic and by defining your risk.

Let's first understand why options tend to lose value:

  1. When you buy an option you are actually placing a bet that the underlying stock will reach or exceed a certain price by a certain date.

  2. If it fails to reach that goal by the date you specified, it expires worthless.


So it has a time premium added to it when you buy it. As it gets closer to the expiration date, the time premium erodes and the option loses value.

When you buy options on a stock, the stock has to move in the right direction and move far enough in time for you to make any money.


How to Make the Odds in Your Favor


The eroding time premium works in your favor when you reverse the logic. Instead of buying options, you sell them. You become the option writer. Any stock/option broker will allow you to do this.

Writing an option is the term used for selling an option you don’t own. It's also known as selling short. You basically are creating the option. Which is why we refer to it as writing options.

How do you write an option? You sell it in your broker account just like you buy or sell stocks. But when you write an option, you indicate an order to “sell to open”. This is because you are opening a transaction.

When I try to explain this to some people, they say they never knew you can sell something you don't own. It's simply doing the trade backwards and it's the trick with putting the odds in your favor with options.

Someday you will have to buy it back to close the deal. That’s done with a “buy to close” order. But you don't always have to buy it back. If the underlying stock never goes past your strike price (we all that in-the-money), then the option expires worthless and you don't really need to buy it back. You just keep all the money you got for it.

But what if it is close to the strike price and you still have time left before expiration? Remember how I said that most options lose value over time? Well, you can buy it back for less than you sold it for, and you keep the difference as your profit.


What Are You Really Selling When You Sell Options?


There are two kinds of options. A PUT and a CALL:

  • When you sell a CALL you are selling someone the right to buy the underlying stock from you at a specific price by a specific date.

  • When you sell a PUT you are selling someone the right to sell his or her owned stock to you at a specific price by a specific date.


Options can have expiration dates from one week to several years.

I like to write 30-day options. The time premium erodes quickly in the last 30 days, and that works in your favor when you sell short.


How it Works when You Already Have the Stock


If you already own a stock and you don’t think it’s going to move much in the next 30 days, but you don’t really want to sell it, you can squeeze some extra money out of it by selling someone else a CALL option on that stock. That is, you are selling him or her the right to “call” the stock away from you at the agreed price. Ah! Now you know why it’s referred to as a CALL option.

If the stock drops or stays the same for 30 days, the option expires worthless and you keep all the money you got for the option.

I know what you're thinking... “But I lost money on the stock.”

Remember that you do this with a stock that you really don’t want to sell. So now you still have the stock and you also have some extra money from the expired call option to make up for the lower price on the stock.



When You Don’t Have the Stock but Would Not Mind Owning It


What if you don’t have a stock and you think you would like to buy it, but you are not sure what it will do.

In that case you can sell a PUT option. This means that you are selling someone the right to sell you his or her stock at an agreed price. If the stock goes down below the agreed price within the 30-day period, they can “put” their shares of the stock to you and you are forced to buy it at the agreed price.

But if the stock goes up in that 30-day period, they can sell it on the open market for more. So they would never exercise their option. They would just let it expire worthless and you keep all of the premium they paid you for the option.



What Can Go Wrong With CALL Options?


Now. In the case where you sold (wrote) a CALL option on the shares you own...

What if the stock goes up over the price you said you’d let the other person have it for. Well, in that case they will “call” the stock away from you at the agreed price.

You are forced to sell your stock at that price. But isn’t that a good price? It’s higher than it was 30 days ago. Plus you get to keep the premium you received for the option too.

The really bad thing that can happen is that the stock shoots really high and you are forced to sell it that that agreed price. You lost out on that tremendous gain. You still have the gain you expected plus the money from the option, but you lost out on the huge gain on the stock.

That's another reason for selling option that expire in 30 days. The chances are slimmer for a stock to make a huge move upward in such as short time. But it happens.


What Can Go Wrong With PUT Options?


In the case where you sold (wrote) a PUT option...

Remember that you are doing this under the condition that you would like to buy the stock.

You don’t ever want to sell a PUT option if you are not willing, or able, to buy the stock. I'll tell you why.

If the stock goes down, then the buyer of the option will sell you their stock at the agreed price. That price is higher than it's selling for on the market, and you have to buy it anyway.

This is why I said to only sell PUT options when you want to buy the stock anyway. You may end up buying the stock if you are wrong with the timing or the price.

It's not really a bad thing because even if this is the case, you are still buying the stock at a lower price than if you had just bought it when you first thought about buying it.

Why is that? Because the PUT option you sold was an offer to buy the stock at a price that is lower than it was when you sold the option. That is, you made an agreement to buy the stock at that price in case the stock goes below that strike price by the expiration date.

So you bought the stock at a better price, plus you got to keep the extra premium you received for the option. So in effect, you paid that much less for the stock.

What's the worst case? If the stock goes really low, you are still buying it at that agreed price. That's not such a great deal, because it is worth so much less on the market. But then again, you did this only in the case where you wanted to buy the stock anyway.



How to Define Your Risk


As I mentioned above, things can go wrong. Especially if you are not on top of things and if you are not managing your trades when you see things changing against you.

It is true that options lose their premium value over time. And now you know how to make this work in your favor. But there is a way to improve your success even further. You can define your risk.

Note that so far I showed you how to sell puts or calls and wait for the premium value to erode. But your risk is still the cost of the underlying stock in the case where it goes in-the-money by crossing the options strike price.

If a put option you sold goes in-the-money, the stock may be PUT to you. That means you have to buy it at the strike (agreed) price.

If a call option you sold goes in-the-money, the stock may be called away from you. This is usually fine if you own the stock. You probably sold an option offering a higher price anyway, and you sell the stock at a profit PLUS keep the premium you got for the option.

But if you don't own the stock, you have to buy it at the higher price in order to sell it at the lower price. That's not a good thing.

So what to do? You can define your risk by buying further out-of-the-money options.

Say you decide to sell a call option to sell XYZ at $50. You can buy a call option to buy the same stock at $60. You will pay less for the $60 call than what you got for the $50 call, so you have a credit on the trade. And what this does is -- it locks you into a total risk of the difference between the two strike prices.

No matter how high the underlying stock goes, you can always exercise your right to buy it at $60. You still have to sell it at $50 if it went over that. But $10 is your total risk.



Success by Terminating the Deal Before Expiration


You don't need to wait for options to expire. You can buy them back at any time to terminate your contract to buy or sell the stock.

If you see it going against you before the 30 days are up, and you change your mind about buying or selling the stock, you can close out the deal by buying back the option.

Since options lose value as they approach expiration, you may still end up buying back the option at a lower price even if the stock started going against you.

This means you can get out of the deal and still make some a nice profit. But there's no guarantee of having that opportunity. This usually happens only when the stock moves against you by just a little.

As you can see, you can have the odds in your favor by selling options rather than buying them. It's just important to understand the entire process and know how to manage your trades. Hopefully I have given you some clues on how this is done.

      Vortrek Grafix - You can find a lot of useful videos from TastyTrade on YouTube as well as on their site. They teach how to sell options in a manner where you define your risk so you put the odds of success in your favor. TastyTrade explained this very well. I talk about them and using the Think-or-Swim platform in my other article - Effective Stock Option Trading with Think-or-Swim.

      Hi Glenn, appreciate the options trading info. Looks like selling options rather than buying options, is a solid percentage play. I like to see live demos in motion so I get more confident with this subject. Hopefully youtube.com will have something on selling options. Thanks for narrowing the focus of what matters from the whole body of this subject way down Glenn.

      Old Poolman - You picked up on another thing I remember learning from Tasty Trade. That is that investing in stocks ties up all your investment. It's all at risk. With these new methods we can define our risk with the spreads. Try asking any professional trader how they define their risk. See if they even understand the question.

      What you learned about options trading before learning Tasty Trade you can throw out. I used to think I knew options trading. Remember that buying options is usually a losers game. Since they expire worthless, most people can lose all their money. That's why we don't buy options. We sell them. We sell premium. The premium errodes and we keep the profit. I'm just articulating what you already know for other readers to understand.

      Thanks and I will probably have some questions for you as I get into some new strategies if that would be OK. I just want to make sure I am totally on top of the credit spreads and iron condors I use now before I try to move on.

      Your correct that stocks are pretty much the same as flipping a coin, could be heads and could be tails. I guess if one owns a basket full of dividend paying stocks that is how they make their money. But that takes a very large trading budget and ties up a huge sum of money for a long time.

      Other option traders I have talked with tell me that through trial and error they have a dozen or so stocks, indexes, and etf's they trade over and over. One gentleman told me these become like old friends and you can fairly well predict what they are going to do at any given time. I hope I can reach that point in my trading career/hobby.

      I now know just about enough about options to be dangerous, but I can see the opportunities for anyone with even a small trading account like mine being able to bring in some extra cash or grow that account. Having that extra edge with otions over buying stocks makes a huge difference. I don't even have enough money in my account to buy some of the stocks I trade, but options let me trade them anyhow.

      My only regret is not getting into options earlier in life.

      Old Poolman - That's right. You want your options to remain out of the money till expiration. Then you an just let it expire and keep 100% profit. That's why a lower delta is better. Delta of 5 means two standard deviations. There is less premium in it, but a better chance of keeping it all.

      Something else I learned from Tasty Trade is that buying and selling in stocks only gives you a 50% chance of success. They can only go up or down. by selling premium and knowing how to place the trade, we increase our chances. But I'm sure you know that part already.

      Your comments and my responses to you are not a waste of time. It benefits all who read this. Your comments are very meaningful. No need to worry.

      My problem is remembering I don't really want the trade to end up In The Money, I just want to collect the premium and let the options expire worthless.

      One thing I learned the hard way was to remember if I was paper trading or live trading. I accidently bought 100 shares of stock I really didn't want because I thought I was paper trading. So, I sold my first covered call and made a little money. Right after the option expired the stock went up for one day and I sold it for a profit.

      I think I have watched every video Tasty Trade has to offer at least once, some twice. The light bulb finally came on, but was still on the dim side. Now it is starting to make sense. I think anyone wanting to get into options trading should start with Tasty Trade and TOS. Besides it costs less per trade if you enter the trade using the Dough Platform.

      Ok, I have wasted enough of your time

      Old Poolman - I may write more hubs on the topic if I see more interest. There are presently only about 70,000 people who understand and follow the Tasty Trade methods at this time. Be careful with reading books on trading. After learning from Tasty Trade I see that most "professionals" don't understand that risk can be defined by buying protection with a further out option. I suggest you just watch as many videos from the Tasty Trade archives as you can. They are all there. Professionals also don't realize that buying stocks is more dangerous because all your money is at risk.

      Glenn - I'm trying hard to gain confidence in my trading ability, but some days it just won't work for me.

      I wish you didn't live so far away, I would love to buy you a cup of coffee and pick your brain for awhile.

      Most of the books I have read actually leave me a little more confused than I was before I read the book. You have a way with words to get the message across and yet keep it simple.

      Perhaps you should write a book on options trading?

      Old Poolman - Thank you. I really appreciate the positive feedback comparing my writing to other trading books. That means a lot coming from someone who understands options trading.

      I have read lots of books on trading options, and none of them explained it as clearly and simply as you do. Job well done.

      redwhiskeypete,

      Options definitely do have time decay. And I have had a lot of hits and misses myself when buying options. That is why I found that the best way to succeed with options is to short them. That way the time decay works in my favor. Many times I let the option expire worthless and I get to keep all the money without ever having to buy it back to close.

      I know you understand this, but when I try to explain this to some people, they say they never knew you can sell something you don't own and buy it back later. That's the trick with making time decay work for you.

      I'm going to look for your hub on DRIPS. Thanks for checking this out and for your comment. Oh and thanks a bunch for the link to my article. Much appreciated.
