ForExTactor, in the example short call/long put is a synthetic short position no? Your risk pofile is topside loss with downside gain. If you are long (spot) and put on that option position on (short call/long put) for expitation one year out (atm), guess what you have?
You have created a swap, no?

You have bought essentially for one value date and sold it for further out via the options (if you hold it to expiration).
You will have earned time/vol and the short and paid on the long (crossing spreads though). Like you suggested, I have no idea of the cost effectiveness of this via options, but like I said before you could just use a swap if you can find a retail broker who offers them.
Where do you think he would be earning his yield from? The tom/next roll on the spot position. So effectively he would earn his yield one day at a time via a swap no?
