New NYSE Group stock surges 25%

NEW YORK — Investors welcomed the NYSE Group Inc. to Wall Street Wednesday, sending shares of the newly public New York Stock Exchange up 25 percent in its first trading session on the Big Board.

After nearly 214 years as a not-for-profit exchange, the NYSE transformed itself into a public company following its $10 billion acquisition of electronic rival Archipelago Holdings Inc. on Tuesday.

"It feels good," said John Thain, chief executive of NYSE Group and the architect of the deal. "Now, of course, we have to demonstrate to our shareholders that there's real value to be had here."

The new company began trading under the ticker symbol NYX Wednesday, with Thain and NYSE Group Chairman Marshall Carter each purchasing 100 shares at $67 in ceremonial first trades; the price was up $2.75 from Archipelago's close Tuesday of $64.25. The stock continued to climb afterward, and finished the session at $80 per share, up $15.75. Volume came to more than 18 million shares, about 36 times Archipelago's average daily trade of just under 500,000 shares.

The second trade after Thain's was actually conducted on the electronic Nasdaq Stock Market, according to Nasdaq officials, where 100 shares were sold at the same $67 price one second after Thain's trade was completed. According to Nasdaq's Web site, nearly 6 million NYX shares traded hands through its system.

With 158 million shares outstanding, the NYSE Group has a market capitalization of roughly $12.6 billion. By way of comparison, the Nasdaq has a market cap of about $3.4 billion, while Chicago Mercantile Exchange Holdings Inc. has a $14.5 billion cap and CBOT Holdings Inc., which operates the Chicago Board of Trade, has a $6.2 billion cap.

The NYSE Group's new equity, the majority of which is still held by the NYSE's former seat holders, will help the exchange expand into new businesses, such as derivatives trading, and could fund acquisitions as well.

The NYSE and Archipelago will continue to operate separately under the NYSE Group umbrella, at least for a short time. Eventually, the exchange hopes to allow its floor traders access to the Arca electronic trading platform, which would give them the ability to trade Nasdaq-listed stocks as well as equity options.
