Hi all The Emini options expiring 30th of AUgust 2013, if in the money at expiry, are the excercised into the into the 20th Sep 2013 E-Mini Future? THanks in advance.
Keep in mind that futures settle differently at month-end than on other days: http://www.cmegroup.com/trading/equity-index/fairvaluefaq.html
I believe all the posts so far have been correct. I don't recall seeing an overlap in ES/EW, but they happen in the Euro futures, including next month. The 6EU3 options expire on 9/6 and are exercised into ECU3 futures that expire on 9/16. The 6E2U3 options expire on 9/13 and are exercised into ECZ3 futures that expire on 12/16. NOTE: the week 2 options are labelled "September" and expire while September futures are still trading, but are exercised into December futures. Very confusing, and this can bite you! You have to read the contract spex very carefully.
