SEC considers centralised cross-exchange display

The US Securities and Exchange Commission (SEC) is considering linking up various stock exchanges to provide a central display of stock quotes.

Although no technical model has yet been agreed on, the SEC has announced a public consultation period that will last until 24 March.

The initiative was suggested by the American Stock Exchange, the Chicago Board Options Exchange, the Pacific Exchange and the Philadelphia Stock Exchange. So far, three implementation models have been proposed.

Sarah Skinner, Internet analyst at Durlacher, said she wasn't surprised at the move, but added the innovation might face resistance from larger exchanges such as Nasdaq.

Skinner told Silicon.com: "There has been a growing need for an easy-to-use cross exchange, following the arrival of more retail investors online. Easdaq is only the start. I expect individual exchanges will start vying for position and ownership, as there is so much money involved, and they can expect to face resistance from bigger players. But I'm sure there will eventually be some degree of consolidation."
