Designated Market Makers

Designated Market Makers 

The cornerstone of the NYSE market model is the Designated Market Maker or DMM. Formerly known as “Specialists,” DMMs are the only participant to have true obligations for maintaining fair and orderly markets for their assigned securities.They operate both manually and electronically to facilitate price discovery during market openings, closings and during periods of substantial trading imbalances or instability. This "high touch" approach is crucial for improving prices, dampening volatility, adding liquidity and enhancing value. DMMs apply keen judgment to knowledge of dynamic trading systems, macroeconomic news and industry specific intelligence, to make their trading decisions. The DMMs are a valuable resource for our listed company community, providing regular communication, making capital commitments, maintaining market integrity, and stepping in during special situations. Read case studies about our DMMs in action or a fact sheet with more details on their roles and responsibilities. You can also watch a video with DMMs on our enhanced trading floor
