Here is the situation: Sold 1 ES put with a strike of 1,300. At expiration the index was at 1,275. it is possible to be assigned 1 ES at 1,300? (So you would now be long 1 ES with a purchase price of 1,300) And if so what month would you get the future in? Lets say you had a June put. I am assuming you could not get a June ES since that is now expired too. Is there a way to end up long 1 ES September? Thanks in advance for any help.
