It’s definitely going to happen.
NYSE Euronext will transfer to the NYSE Arca all the ETF listings from the former American Stock Exchange, renamed the NYSE Alternext US after its purchase by the NYSE. On Monday, the Arca began trading 74 PowerShares ETFs after the ETF sponsor transferred their primary listings to the NYSE’s electronic stock exchange. With the new PowerShares ETFs, the NYSE Arca has primary listings for 423 ETFs and 82 ETNs. According to the NYSE, the NYSE Arca holds 59% of the ETF and ETN assets under management in the U.S., or nearly $353 billion. When the transfer is done, the NYSE Alternext will only trade equities that had listed on the Amex.
