Here's an easy one, AMZN closed at exactly 3200. so, the ITM(In the money) (long guts) position of 3190 calls and 3210 puts cost 83.60(calls) and 79.39( puts) for a combined 162.99. Worst case, the stock closes at 3200 next Friday. You get a total of $20...$10 for the calls and $10 for the puts. which is "The ITM position will at least give you something in every scenario"
On the other hand, the OTM(out of the money) position of 3210 calls and 3190 puts cost $73.60(calls) and $68(puts) for a combined $141.60 If, worst case, AMZN expires anywhere between 3190 and 3210 you get zero, which is "whereas the OTM may not"
I know this may seem complicated, but it's not. In the worst case with the In the Money position, you get $10 for puts plus $10 for calls, total $20... and in the worst case in the Out of the Money position, you get $0.
Actually, it don't even seem complicated.
