What if the Amex receives no MOC orders in a particular security? How will it be publicly known that the Amex is not the official close?
While the Amex believes that this will be an unlikely and infrequent scenario, contingencies are in place if this occurs. If the Amex receives no MOC orders, the Amex will not post an AOCP and firms can revert to the NOCP for that stock on that particular day. In addition, the Amex posts AOCP information on the Amex website starting at 4:15 p.m. on a daily basis. If no AOCP is posted for a given stock, it can be assumed that the Amex is not the official close on that day.
