Select Your DMM

Identifying your Designated Market Maker (DMM) is the beginning of an important partnership that perseveres well beyond listing day. DMMs have an obligation to maintain fair and orderly markets for your stock. They facilitate price discovery during market openings, closings and during periods of substantial trading imbalances or instability. DMMs provide listed companies regular communication and step in to make capital commitments and maintain market integrity during special situations.

Contact our listings team to get a list of eligible DMMs, contact information for the DMM firms and other information related to DMM selection.
