Calculating American Early Exercise Premium
 
|
Hi,
I'm trying to calculate the european option price from an american by taking out the early exercise premium. I first use FDDividendAmericanEngine to calculte the implied vol, then use Barone-Adesy and Whaley engine and Black Scholes engines to calculate the american and european prices which I thought would allow me to get the american premium. But, when I do this calculation, my two option prices always match. Do you think my above thinking is flawed or it could be due to a programming error on my part. Anycase, if you have a better alternative for what I'm trying to do, I really appreciate to hear that too. Thank you very much. C |

mmm... in the case of a call option on a non-dividend paying stock the
american and european prices are the same. Do you have dividends? What about put options? ciao -- Nando On Mon, Aug 25, 2008 at 5:30 PM, nabbleuser2008 <[hidden email]> wrote: > > Hi, > I'm trying to calculate the european option price from an american by > taking out the early exercise premium.

thanks.
the stocks I've tried do have the dividends. I didn't try the puts since i'm only interested in calls for my current work, but I can check the puts. thank you. C

Upon further investigation, for call options, I noticed that the two prices differ by a small amount in some cases, specially for the longer maturities, but the difference is in 1/100th of a penny, so the difference is not significant when pricing to the nearest penny.
Does that observation make sense ? I expected to see bigger premium, specially for longer maturities. I am looking at upto almost 2 years maturity. Thanks much for any suggestions, and comments ..

It would help to know the specs of the option you're trying to price:
strike, vol, expiry, spot value, interest rate, dividends...
