Mark, I'm sure it was a brain fart, but that's not a collar. In a collar with a long stock you short the call and buy the put.
I usually start the trade with a covered call (long stock, short call). I'll add the long put (turning it in to a collar trade) if the stock goes very bearish. Usually if it breaks a support line. Regards, Chad
