70% of options expire purposeless to the buyer! That means 70% expire profitable to the seller.
Garbage! incredible garbage! Absolutely amazing garbage! The logic in this declaration is just plain wrong and of course the website does not have statistics to urge on their claim.
To be fair this website was not the without help area I have come across a assertion behind this. I have in fact seen a figure of going on to 90% quoted. However even if it is a common belief does not make it correct.
Lets first have a think not quite the logic, then lets see at some stats and come to some real conclusions.
Profit Logic
Lets receive 70% of options reach expire worthless. How can anyone appeal conclusions as to the profitability of a long trade or a rude trade? You helpfully cannot.
If you sell an out of the ordinary at say 10pts, you could then watch it go to 100 or 200pts and wipe out all the allowance in your account. The publicize may next point of view around and eventually look the different expire worthless, but that does not target your trade has been profitable. This is not nit picking. This is genuine moving picture trading - things concern taking place and alongside and you cannot always afford to sit upon a approach and hope for a zero value at expiry.
It is suitably not possible to glamor a conclusion approximately profitability based on expiration statistics.
The statistics
In a wedding album entitled Options on Futures by Summa and Lubow they quote the 80% figure and it is backed in the works by numbers from the Chicago Mercantile row (CME).
In a section entitled The Numbers talk for Themselves, they act out a table of data sourced from the CME. The numbers represent the percentage of options that expire worthless. The data from the book is as follows:
YearCME optionsS&P optionsS&P putsS&P calls
199776.381.794.154.8
199875.882.293.143.9
199977.584.794.566.7
1997-9976.683.394.055.3
Assuming we have no defense the doubt these statistics, later this seems to back up occurring the well-liked belief. upon cautious reading however, it appears the figures represent lonesome those options that are held to expiration and not those that are closed out OR exercised before expiration (remember we are dealing behind American style options here in view of that some can be exercised previously expiration).
Maybe we reach not have the gather together picture...
I moreover came across some more stats from the Chicago Board Options row (CBOE) that I thought were interesting. Their figures are:
- Approximately 10% of options are exercised;
- 50-60% of options positions are closed prior to expiration;
- The enduring (about 30 40%) are held to expiry.
At first these figures might see rather contradictory, but they are not. The CME numbers are based upon options that are held to expiry. That is they do not insert options that are exercised or closed since expiry and thats 60-70% of all options according to the CBOE.
If we say you will both exchanges statistics as fact, after that drawing a conclusion from deserted the expiry numbers could be a bit biased.
Think practically the CBOE numbers for a moment. The 10% that are exercised ahead of time would in every but utterly scarce cases be in-the-money (why else would you exercise?) If we take thus that and no-one else in-the-money options are exercised, later this would depart more out-of-the-money options heading to expiry than in-the-money.
What not quite the options that are closed in the past expiry? One could hazard a guess that most options closed near expiry would be either in-the-money, at-the-money or just out-of-the-money.
Why? In-the-money options will feat more and more similar to the underlying the deeper they are in-the-money and the closer they get to expiration. Holding in-the-money options so will carry more risk. This could be a explanation why some holders may want to near their in-the-money positions prior to expiration. Out-of-the-money options on the supplementary hand may be worth categorically tiny and sustain little risk (low delta/gamma/theta/vega). for that reason you might tell there is larger fortuitous of an out-of-the-money complementary subconscious held until expiration.
Therefore, the 50%-60% of options that the CBOE affirmation are closed in the past expiration could after that be weighted towards in-the-money options. For the numbers below, we will tolerate the split is 60-40% (60% in-the-money and 40% out-of-the-money).
So then, the majority of the 30-40% that go on to expiry would correspondingly be out-of-the-money and of course would expire uselessness once out-of-the-money options do. Does that objective you should be a net seller? Does that goal 70% of options expire profitable to the seller?
Lets proceed subsequently some numbers. Lets say we have an exchange behind 1,000 way in other contracts.
- First, 10% of the options (all in-the-money) are exercised prematurely leaving 400 in-the-money and 500 out-of-the-money. There are 900 options remaining.
- Then 55%* or 550 of the initial pool are closed out rejection 350 right of entry contracts. (* 55% is half pretension in the company of the 50-60% CBOE number.)
- Of these 550, we dependence to estimate how many are in-the-money and how many are out-of-the-money. back we have standard a weighing towards in-the-money options, lets take 60% of these are in-the-money and 40% are out-of-the-money.
- In the end, we have 350 contracts manage to expiration.
Based upon our calculations, that would leave 70 in-the-money options and 280 out-of-the-money options that will rule until expiration. (see table). Based upon the one assumption above, 80% of the options that will go to expiry are out-of-the-money and for that reason will expire worthless.
TOTALIn-the-moneyOut-of-the-money

Remaining900400500
Closed positions (55% of 1000)550330220
Option to trade to expiry35070 or 20%280or 80%
So now the figures make sense. Perhaps 80% of options that manage to expiry pull off expire worthless. (Perhaps the genuine figure is 70% or 90%.) However that is not the similar as motto 80% of every options expire worthless. Can you see the difference? Furthermore, coming to the conclusion that is it improved to be a seller than a buyer from a single biased statistic in imitation of this is plain nonsense.
In a topic as soon as that of as options trading, it is easy to acquire caught taking place subsequently statistics, but if we take the mature to think and research in the past drawing conclusions, subsequently surely we will become augmented traders.
