Schwager and covered calls

["Andy Dunn" <andy@xxxxxxxx>]

I have a friend who is using covered calls.

I am almost positive that I read in one of Schwagers books that he explains that a covered call is mathematically the exact same as an outright position but costs twice as much in comission...I think it was during an interview. Does anyone remember this, and which book it was in and maybe the page? I am trying to help out a friend with the knowledge.

thanks

Andy
