You can write an option using a covered call strategy (any broker will let you do that), or you can write an option w/out owning the underlying stock (which is what I have described). So yes, I was talking about a naked put option. I didnt think I needed to specify covered or naked due to the context. Sorry.
I could be wrong, but I dont think this poster was really looking at a covered call. With $3k he wouldnt be able to pay his cell phone bill writing covered calls.
