Stock on average (assuming put-call parity or whatever its call, which is not likely the case, but just assuming that for simplicity for example purposes) you win 40 cents, pretty much risk free.
Any further questions?
Yeah. The entire point of put-call parity (or, ya know, whatever it's called
) is "no arbitrage" - meaning that no combination of puts and calls will result in a greater return than the underlying. Otherwise, you'd buy (sell) synthetic longs (shorts) and immediately close them out by selling (buying) the stock. Rinse, repeat, billionaire by day's end.So I'm afraid the "put-call whatever" is going to create a bit of inconvenience for you if you try what you've suggested in real life. But give it a shot and post the blotter... it'll be a learning experience for someone.
