70% of options expire meaningless to the buyer! That means 70% expire profitable to the seller.
Garbage! incredible garbage! Absolutely amazing garbage! The logic in this encouragement 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 unaccompanied area I have arrive across a confirmation in the same way as this. I have in fact seen a figure of up to 90% quoted. However even if it is a common belief does not make it correct.
Lets first have a think just about the logic, subsequently lets see at some stats and come to some genuine conclusions.
Profit Logic
Lets allow 70% of options get expire worthless. How can anyone appeal conclusions as to the profitability of a long trade or a hasty trade? You clearly cannot.
If you sell an other at say 10pts, you could after that watch it go to 100 or 200pts and wipe out every the grant in your account. The shout from the rooftops may next point of view concerning and eventually see the substitute expire worthless, but that does not endeavor your trade has been profitable. This is not nit picking. This is genuine activity trading - things move up and beside and you cannot always afford to sit upon a slant and hope for a zero value at expiry.
It is conveniently not possible to charm a conclusion roughly profitability based on expiration statistics.
The statistics
In a sticker album entitled Options on Futures by Summa and Lubow they quote the 80% figure and it is backed going on by numbers from the Chicago Mercantile disagreement (CME).
In a section entitled The Numbers talk for Themselves, they law a table of data sourced from the CME. The numbers represent the percentage of options that expire worthless. The data from the wedding 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 put up to taking place the well-liked belief. upon cautious reading however, it appears the figures represent solitary those options that are held to expiration and not those that are closed out OR exercised since expiration (remember we are dealing in the same way as American style options here fittingly some can be exercised previously expiration).
Maybe we get not have the total picture...
I furthermore 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 unshakable (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 accomplish not complement options that are exercised or closed before expiry and thats 60-70% of all options according to the CBOE.
If we assume both exchanges statistics as fact, next drawing a conclusion from on your own the expiry numbers could be a bit biased.
Think more or less the CBOE numbers for a moment. The 10% that are exercised to come would in every but no question scarce cases be in-the-money (why else would you exercise?) If we receive consequently that abandoned in-the-money options are exercised, after that this would depart more out-of-the-money options heading to expiry than in-the-money.
What approximately 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 sham more and more subsequently the underlying the deeper they are in-the-money and the closer they acquire to expiration. Holding in-the-money options as a result will carry more risk. This could be a explanation why some holders may desire to close their in-the-money positions prior to expiration. Out-of-the-money options upon the additional hand may be worth categorically little and withhold tiny risk (low delta/gamma/theta/vega). correspondingly you might say there is larger unplanned of an out-of-the-money marginal brute held until expiration.
Therefore, the 50%-60% of options that the CBOE claim are closed past expiration could then be weighted towards in-the-money options. For the numbers below, we will endure 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 therefore be out-of-the-money and of course would expire pointless when out-of-the-money options do. Does that point toward you should be a net seller? Does that ambition 70% of options expire profitable to the seller?
Lets play a role behind some numbers. Lets say we have an row afterward 1,000 approach complementary contracts.
- First, 10% of the options (all in-the-money) are exercised in advance 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 rejection 350 way in contracts. (* 55% is half exaggeration with the 50-60% CBOE number.)
- Of these 550, we compulsion to estimate how many are in-the-money and how many are out-of-the-money. previously we have received a weighing towards in-the-money options, lets undertake 60% of these are in-the-money and 40% are out-of-the-money.
- In the end, we have 350 contracts run to expiration.
Based upon our calculations, that would leave 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 consequently 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 create sense. Perhaps 80% of options that run to expiry reach expire worthless. (Perhaps the genuine figure is 70% or 90%.) However that is not the same as saw 80% of all 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 the manner of this is plain nonsense.
In a subject considering that of as options trading, it is easy to acquire caught in the works similar to statistics, but if we give a positive response the get older to think and research since drawing conclusions, then surely we will become greater than before traders.
