NYSE Arca Is The World’s Premier ETF Platform - Largest Public ETF Liquidity Pool in the U.S. - Leading Share Of Trading, Total Listings And Assets Under Management - NYSE Group Markets Have 220 Primary ETF Listings, 41% Of Total ETF Listings

NYSE Euronext (NYSE Euronext: NYX) today announced that the first group of 14 WisdomTree ETFs completed their scheduled transfer from the NYSE to NYSE Arca on Oct. 10, 2007.    NYSE Euronext expects the phased transfer of all NYSE listed ETFs to NYSE Arca to be completed by year-end.

With 67% of the total assets under management and over 42% of ETF trading volume for all U.S. ETFs, NYSE Arca is the first electronic stock exchange to offer investors the benefits and stability of a dedicated liquidity provider in the form of a Lead Market Maker for each primary listed ETF.    NYSE Arca offers a proven market structure for trading both listed and unlisted ETFs. 

“Our industry leading market quality and continued endorsements from the ETF issuers have been fantastic support for our unique exchange model,” said NYSE Euronext Senior Vice President, Exchange Traded Funds and Indexes, Lisa Dallmer.   “Across all ETFs, NYSE Arca is driving the NBBO 85% of the time, providing the tightest quoted spread of 0.04% and the largest depth of quote across all exchanges, year-to-date through September[1].”

“We are pleased to continue our strong relationship with NYSE Euronext by listing a total of 31of our products on NYSE Arca,” said WisdomTree Investments CEO, Jonathan Steinberg.  “With many of our funds trading on NYSE Arca as their primary market, we are confident that this platform’s market structure will continue to provide superior market quality and exceptional service for investors in WisdomTree ETFs.”

Initiated by specialist firms and undertaken in conjunction with issuers, NYSE Group concluded that the most efficient and industry-preferred market structure for listing and trading ETFs is the NYSE Arca platform, which utilizes dedicated liquidity providers in the form of Lead Market Makers (LMMs).   This model, which requires LMMs to maintain certain performance obligations for all NYSE Arca listed securities, benefits investors and issuers with consistent liquidity and more orderly trading than a market model without such structure.   NYSE Arca has offered this market model to all NYSE Arca primary listed stocks and ETFs since 2006.

NYSE Arca’s all-electronic market is the single largest public liquidity pool for ETFs in the U.S.  and presents a compelling value proposition for investors and market professionals.  So far in 2007, NYSE Arca handled 42.3% of all ETF shares traded in the U.S. , representing an average volume of approximately 216.36 million shares per day.
