70% of options expire meaningless to the buyer! That means 70% expire profitable to the seller.
Garbage! amazing garbage! Absolutely unbelievable garbage! The logic in this confirmation is just plain wrong and of course the website does not have statistics to help their claim.
To be fair this website was not the by yourself area I have arrive across a statement considering this. I have in fact seen a figure of happening to 90% quoted. However even if it is a common belief does not create it correct.
Lets first have a think very nearly the logic, next lets see at some stats and come to some real conclusions.
Profit Logic
Lets take 70% of options get expire worthless. How can anyone charm conclusions as to the profitability of a long trade or a quick trade? You usefully cannot.
If you sell an marginal at say 10pts, you could later watch it go to 100 or 200pts and wipe out every the child support in your account. The market may subsequently slope roughly speaking and eventually see the unconventional expire worthless, but that does not objective your trade has been profitable. This is not nit picking. This is genuine vigor trading - things have emotional impact going on and the length of and you cannot always afford to sit upon a aim and hope for a zero value at expiry.
It is handily not possible to magnetism a conclusion practically profitability based on expiration statistics.
The statistics
In a lp entitled Options upon Futures by Summa and Lubow they quote the 80% figure and it is backed taking place by numbers from the Chicago Mercantile quarrel (CME).
In a section entitled The Numbers talk for Themselves, they produce an effect a table of data sourced from the CME. The numbers represent the percentage of options that expire worthless. The data from the sticker album 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 reason the doubt these statistics, next this seems to incite up the popular belief. on careful reading however, it appears the figures represent without help those options that are held to expiration and not those that are closed out OR exercised back expiration (remember we are dealing next American style options here in view of that some can be exercised in the past expiration).
Maybe we attain not have the cumulative picture...
I furthermore came across some more stats from the Chicago Board Options dispute (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 long-lasting (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 reach not enhance options that are exercised or closed in the past expiry and thats 60-70% of all options according to the CBOE.
If we give a positive response both exchanges statistics as fact, next drawing a conclusion from single-handedly the expiry numbers could be a bit biased.
Think virtually the CBOE numbers for a moment. The 10% that are exercised upfront would in all but categorically rare cases be in-the-money (why else would you exercise?) If we acknowledge appropriately that unaided in-the-money options are exercised, later this would leave more out-of-the-money options heading to expiry than in-the-money.
What not quite the options that are closed before 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 play-act more and more subsequent to the underlying the deeper they are in-the-money and the closer they acquire to expiration. Holding in-the-money options fittingly will carry more risk. This could be a excuse why some holders may want to near their in-the-money positions prior to expiration. Out-of-the-money options upon the other hand may be worth extremely tiny and keep little risk (low delta/gamma/theta/vega). fittingly you might tell there is larger unplanned of an out-of-the-money marginal physical held until expiration.
Therefore, the 50%-60% of options that the CBOE allegation are closed since expiration could in addition to be weighted towards in-the-money options. For the numbers below, we will say you will 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 upon to expiry would correspondingly be out-of-the-money and of course would expire worthless once out-of-the-money options do. Does that strive for you should be a net seller? Does that endeavor 70% of options expire profitable to the seller?
Lets play later than some numbers. Lets tell we have an difference of opinion as soon as 1,000 approach marginal contracts.
- First, 10% of the options (all in-the-money) are exercised in the future desertion 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 desertion 350 edit contracts. (* 55% is half exaggeration amid the 50-60% CBOE number.)
- Of these 550, we need to estimate how many are in-the-money and how many are out-of-the-money. since we have time-honored a weighing towards in-the-money options, lets allow 60% of these are in-the-money and 40% are out-of-the-money.
- In the end, we have 350 contracts govern to expiration.
Based upon our calculations, that would depart 70 in-the-money options and 280 out-of-the-money options that will govern 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 therefore will expire worthless.

Remaining900400500
Closed positions (55% of 1000)550330220
Option to trade to expiry35070 or 20%280or 80%
So now the figures create sense. Perhaps 80% of options that control to expiry get expire worthless. (Perhaps the real figure is 70% or 90%.) However that is not the similar as maxim 80% of every options expire worthless. Can you see the difference? Furthermore, coming to the conclusion that is it greater than before to be a seller than a buyer from a single biased statistic when this is plain nonsense.
In a subject following that of as options trading, it is easy to get caught going on subsequently statistics, but if we say you will the period to think and research previously drawing conclusions, then surely we will become improved traders.
