Background about listing on NYSE Arca^SM

NYSE Euronext’s multiple market platforms share similar attributes, providing superior trading quality over competitor models. In the NYSE Arca market model, listed issuers participate in the selection of a “Lead Market Maker” responsible for maintaining tight spreads and providing the opportunity for price improvement. NYSE Arca has captured a significant portion of trading in Nasdaq stocks by providing excellent market quality, as measured by its superior effective spreads and speed.

NYSE Arca listing standards extend the NYSE’s focus on providing a listing and trading venue for quality companies.

• Emerging growth companies – both domestic as well as non-US companies - have the opportunity to list on NYSE Arca as an alternative listing venue, enabling NYSE Euronext to compete for smaller-sized companies that previously did not qualify.

• NYSE Arca is a globally recognized, fully electronic platform that trades around one billion shares each day on average, and that is growing quickly.

• NYSE Arca-listed companies participate in the selection of a “Lead Market Maker” responsible for maintaining depth and quality of trading in the stock. The “Lead Market Maker” brokerage firm has quote and execution obligations and the responsibility for keeping tight spreads in the stock – resulting in the superior market quality that issues have come to expect. 

• NYSE Arca's affiliation with NYSE, through their common parent NYSE Euronext, is attractive to companies considering a listing on NYSE Arca.  These companies have the ability to choose their own lead market maker which provides additional liquidity in their shares.  In addition, NYSE Arca listed companies have the opportunity, once they qualify, to seamlessly transfer to the NYSE without paying the initial listing fee.
