What percentage of in the money call options get exercised?

I always heard that most call options dont get exercised. If I own the stock and sell the call option, what are the odds that the person who bought the option will let it expire if it is in the money?

 

100% guarantee your stock gets called away if the options are ITM when they expire. No free lunch.

 

Odds of in the money call *not* being exercised at expiration are zero. They are automatically exercised.

 

Several years ago I was not paying attention and let a small amount of in the money options expire. What happened to the writer of those options?

 

If they were $0.25* - or more - ITM then the writer lost his shares.

* I believe it was $0.25 a few years ago.

 

Who gets the shares on the cheap when someone doesnt exercise them? The market makers? Etrade?

 

Holder of the long calls.

 

what if the holders of the long call options forget to exercise them?

 

Then he is the proud owner of 100 shares per contract on Monday.

 

I am assuming from your wording there is a differance between a call and a long call option...
