The American Stock Exchange has amended its Rule 126A-AEMI, which implements the order protection requirements of Regulation NMS on AMEX’s NMS-compliant platform, AEMI, to include additional exceptions and exemptions from those requirements. The amended rule adds the “stopped order” exception set out in Regulation NMS Rule 611(b)(9), as well as the exemptions for “qualified contingent trades” and “sub-penny trade-throughs,” to the list of circumstances under which AEMI may execute a trade that would otherwise constitute a trade-through without simultaneously generating an Intermarket Sweep Order to the away protected quotation.
